A Conferência

A conferência internacional Sustainable Building 2010 Brazil (SB10Brazil) é a última da série de conferências regionais em construção sustentável organizadas este ano como preparação para a SB Mundial, em 2011, a ser realizada em Helsinki, na Finlândia. Trata‐se da quinta edição mundial da conferência, que é a maior neste assunto na esfera científica. A organização, em nível mundial, é apoiada pelo CIB (International Council for Research and Innovation in Building and Construction), UNEP (United Nations Environment Programme) e iiSBE (International Initiative for a Sustainable Built Environment). No Brasil, é uma colaboração entre o CBCS e uma coalizão de universidades brasileiras líderes no tema: UNICAMP, UFES e UFSC, tendo como chairs Vanessa Gomes (UNICAMP, iiSBE, CIB), Vahan Agopyan (USP, CIB) e Marcelo Takaoka (CBCS, UNEP/SBCI).

A SB10Brazil será realizada conjuntamente com o Simpósio Brasileiro de Construção Sustentável – SBCS10, em sua terceira edição, nos dias 08 e 09 de novembro de 2010, no Amcham Business Center. No dia 10 de novembro, a sede do evento passará a ser o Sinduscon‐SP, onde a programação será concluída por três workshops simultâneos, seguidos de um seminário dedicado à análise do ciclo de vida e à discussão para sua implementação no Brasil no curto prazo.

Os organizadores da SB10Brazil encorajam os institutos de pesquisa, universidades e empresas a se reunirem em São Paulo, e se engajarem em colaboração internacional para o intercâmbio de informações, formação de redes de empresas e grupos de pesquisa e desenvolvimento de competências empresariais em sustentabilidade.

Os idiomas oficiais da conferência são o Português e o Espanhol, porém, devido ao interesse internacional pelo tema, foram aceitos também resumos e artigos em inglês. Versões atualizadas e ampliadas dos melhores trabalhos da SB10Brazil, além de artigos selecionados de convidados nacionais e internacionais, serão publicadas em um número especial da Revista Ambiente Construído, publicada pela ANTAC, em 2011.

Uma publicação pós‐evento, editada por Vanessa Gomes, Vahan Agopyan, Maristela G. da Silva, Roberto Lamberts, Doris Kowaltowski e Marina Ilha, está sendo produzida e será em breve publicada, e incluirá textos de keynote speakers e autores convidados, além de um extrato dos melhores artigos submetidos à conferência, de uma análise do encaminhamento da pesquisa neste tema no país em relação à tendência internacional, do relato das sessões técnicas e da agenda traçada a partir do seminário dedicado à análise do ciclo de vida.

Instrumentos de mudança

A SB10Brazil marca o décimo aniversário do CIB 2000 ‐ From theory to practice, uma das primeiras grandes tentativas de estimular e facilitar a aplicação dos conceitos de construção sustentável no Brasil e América Latina. Ao longo desta última década, os esforços enfocaram o nivelamento de conhecimento, o desenvolvimento de uma visão de futuro mais sustentável para o país e a exploração de aspectos de gestão e inovação para construção sustentável.

A SB10Brazil assumiu o desafio de auxiliar a instrumentar esta mudança. Com a coordenação cientifica de Marina Ilha (UNICAMP), a SB10Brazil convidou ao envio de contribuições e estudos de casos para estimular a implementação e a demonstração de avanços em, entre outros temas e sub‐temas:

1) Projeto e construção avançados;

2) Habitação e assentamentos de interesse social mais sustentáveis e financeiramente acessíveis;

3) Reformas e manutenções;

4) Modelos urbanos e infra‐estrutura;

5) Políticas e legislações;

6) Processo integrado de entrega de empreendimentos e modelos de contratação atualizados;

7) Metodologias e ferramentas de avaliação da sustentabilidade;

8) Gestão sustentável de facilidades;

9) Modelos de negócios para construção;

10) Educação e treinamento.

Bem vindos à Conferência SB10Brazil!

Atualmente, abundam números sobre os impactos ambientais, econômicos e sociais relacionados ao ambiente construído e em um de seus componentes mais visíveis, as edificações. Edifícios em países desenvolvidos respondem por cerca de 30 a 40% do uso total de energia, com proporções semelhantes de emissão de gases de efeito estufa e outros poluentes. Países em desenvolvimento apresentam tendências próximas ou cada vez mais semelhantes.

Vanessa Gomes Chair SB10Brazil

Parcela importante do consumo de materiais e geração de resíduos, consumo de água e geração de efluentes e substâncias contaminantes, emprego e exposição dos ocupantes do espaço edificado a substâncias tóxicas são outros temas recorrentes, sempre com números igualmente importantes.

Esta é a parte conhecida do problema. No entanto, problema ainda maior está no que não se conhece. Ainda inexistem no Brasil bases de dados abrangentes e capazes de caracterizar o desempenho típico de componentes do ambiente construído, seja na etapa de projeto, construção ou uso e operação. Considerações pós‐vida útil parecem assunto ainda mais distante. Isto impede análises informadas e comparações, seja internamente ou com dados internacionais; a construção de um conjunto de resultados robusto, acessível, e que tenha significado no contexto de análise; e a definição de metas realmente modificadoras. A máxima “só se pode gerenciar o que se conhece” aplica‐se em sua acepção mais completa. Basta analisar o histórico das nações mais avançadas em projeto e construção sustentável para perceber que suas trajetórias incluem forte investimento financeiro, direcionamento de esforços de pesquisa e parceria com o setor produtivo exatamente na consolidação e publicação destas informações fundamentais. Saltar etapas aqui significa não somente retardar, como também por em risco o avanço consolidado em direção a um setor de construção e um ambiente construído mais sustentáveis.

Há pelo menos uma década se adia a discussão e implementação coordenada de análise de ciclo de vida no setor de construção do país. Enquanto isso, vem‐se adotando caminhos inócuos para seleção de materiais, componentes e sistemas construtivos, que dão a falsa impressão que se está avançando, mas na verdade desviam a atenção, sem que a real base do problema seja atacada e uma solução efetivamente apontada.

Declarações ambientais de produtos, alvo de normas internacionais, vêm sendo desenvolvidas em parceria com a indústria de diversos países. Este é o primeiro passo para se estabelecer uma relação de confiança com o setor produtivo e com o desempenho ambiental dos produtos lançados no mercado de construção, indo além do patamar mínimo de discussão da qualidade dos produtos.

Normas relacionadas a edifícios, sistemas de avaliação e códigos estão experimentando uma mudança fundamental na forma como abordam projeto sustentável, distanciando‐se da metodologia prescritiva para uma abordagem que enfatiza desempenho quantificável. Estes instrumentos estão atribuindo maior importância à análise do ciclo de vida (ACV ou LCA, do acrônimo original em inglês), com foco em verdadeiras medidas ambientais, e no fortalecimento da ligação entre projeto e desempenho real da edificação no longo prazo.


Sustainable Building 2010 Brazil | Instrumenting Change ix

No nível de produtos de construção, uma mudança semelhante está acontecendo na medida em que as etiquetagens estão se afastando dos selos ISO tipo I e tipo II, em direção aos ISO tipo III, as chamadas declarações ambientais de produtos (EPDs). No entanto, os sistemas, normas e códigos ainda refletem uma mescla de elementos objetivos e subjetivos – de processo, medidas prescritivas e desempenho – que torna difícil a evolução de forma completa para normas de construção sustentável.

Neste contexto, esta apresentação enfocará as dificuldades mais relevantes, assim como algumas proposições apontadas por conferencistas e autores convidados para sua resolução.

Wayne Trusty, do ATHENA Sustainable Materials Institute, Canadá, apresenta análise de ciclo de vida, seus principais conceitos e as tendências mundiais recentes em seu desenvolvimento e implementação prática para informar decisões no setor da construção. Julien Hans, da divisão ambiental do CSTB, França, discute a experiência francesa, que experimenta a evolução da consolidação de declarações ambientais de produtos em uma base de dados para um sistema de avaliação ambiental de edifícios. Christer Sjöström, do KTH, Suécia, apresenta a perspectiva da previsão de vida útil e a necessidade de sua consideração para a correta avaliação da contribuição ambiental dos materiais, sistemas e componentes no conjunto construído. Cássia Ugaya adiciona tempero nacional e contexto em desenvolvimento à discussão, ao apresentar a proposição da Iniciativa para análise do ciclo de vida do Programa Ambiental das Nações Unidas (UNEP LCA iniciative) para consideração de aspectos sociais em análise do ciclo de vida, originalmente restrita à dimensão ambiental.

O campo de projeto sustentável tem se apoiado em pelo menos duas grandes apostas: modelo de informação de edificações e processo integrado de entrega de empreendimentos. O chamado modelo de informação de edificações (BIM), por sua capacidade de agregar e articular dados, características e informações de todas as facetas e disciplinas envolvidas em projeto e construção, e já nos estágios mais iniciais de projeto, tem se apresentado como candidato mais promissor a conectar informações ambientais, como de análise de ciclo de vida, aos elementos tradicionalmente considerados na produção de edificações. Configura o paralelo, em termos de ferramental, à reorganização, em termos de composição e articulação de equipe, pressuposta pelo processo de projeto integrado. O conceito de entrega integrada de empreendimentos se apóia igualmente em ambos para o alcance de metas ambientais agressivas.

Martin Fischer, do Center for Integrated Facility Engineering (CIFE), da Stanford University, EUA, traz a sua visão e experiência na implementação prática de projeto e construção virtual (VDC), uso de modelos multidisciplinares de desempenho em projeto e construção, e aplicação de modelagem 4D para aumento de produtividade e melhoria do planejamento em projeto, melhoria do desempenho e aumento de sustentabilidade no ciclo de vida.

Edificações desempenham um papel central no cenário do aquecimento global, considerado o maior desafio já enfrentado pela humanidade. É sabido que edifícios estão entre os maiores consumidores de energia, em muitos países com matrizes energéticas predominantemente com fósseis.

No campo de projeto, a disponibilização de abordagens e tecnologias de última geração poderia sugerir obsolescência da fundamentação e ferramentas tradicionais para entendimento conceitual das implicações das decisões arquitetônicas e construtivas. Como a maior parte da energia consumida por edifícios é, em boa extensão, impactada pelo seu relacionamento com o sol, edifícios mais sustentáveis devem, necessariamente, ser solar‐responsivos, e não apenas cobertos por coletores solares. Adicionalmente, muitos princípios de projeto solar usualmente aceitos são incorretos.


Sustainable Building 2010 Brazil | Instrumenting Change x

Norbert Lechner, professor emérito da Alburn University, EUA, vem demonstrar que avanços e soluções arrojadas só podem ser construídos a partir do conhecimento sólido e do domínio de conceitos essenciais de projeto para baixo uso de energia, e que existem ferramentas poderosas de ensino e prática de projeto para desmistificar tais impressões, facilitar e aumentar a precisão da tomada de decisões de projeto.

A ênfase em redução do uso de energia em edificações vem produzindo uma das discussões mais efervescentes em nível internacional: edifícios neutros no uso de energia (net‐zero). O movimento para desenvolver e implementar os chamados Net Zero Energy Buildings (NZEB) vem ganhando força em diversos países por sua potencial contribuição para elementos multi‐relacionados, como aumento rápido do custo de energia, pressão para tratar de mudanças climáticas, migração de independência para auto‐suficiência de energia e a pressão ética pra reduzir o consumo de energia. Diferentes agências governamentais estão estabelecendo metas em horizontes de tempo curtos. Charles J. Kibert, da Rinker School of Civil Construction, University of Florida, traça uma visão geral destas iniciativas e exemplos de projetos que atingiram o objetivo proposto, e discute se de fato os chamados edifícios net‐zero efetivamente constituirão a próxima geração de edifícios de alto desempenho.

Muitos governos, instituições e grandes organizações estão se engajando em assuntos relacionados a causas e impactos das mudanças climáticas. A área de mitigação é objeto de amplo debate público e de estabelecimento de metas, porém com mínima ação imediata. Ações relacionadas à adaptação e à remediação começam a ser estabelecidas, já que atividade paralela no longo prazo tem se tornado mais aceitável em alguns países. No entanto, segundo o IPCC, há grande probabilidade de ocorrência de desastres naturais, nem sempre de forma gradual. Numa abordagem de intervenção em escala urbana possível imediatamente, Werner Sobek, professor e coordenador do Institute for Lightweight Structures and Conceptual Design (ILEK), da University of Stuttgart, Alemanha, propõe o emprego de estruturas leves para evitar a formação de ilhas de calor. Já Nils Larsson, diretor executivo da International Initiative for a Sustainable Built Environment (iiSBE), entende que uma das poucas opções realistas para ação significativa passa, necessariamente, pelo envolvimento de organizações públicas e privadas‐chaves, principalmente em países desenvolvidos, para desenvolver e manter seus próprios planos de contingenciamento para reduções rápidas e profundas de emissões de gases‐estufa (GEEs), antecipando‐se ao momento em que os impactos forcem os governos a impor medidas de emergência e assegurando que as medidas sejam efetivamente implementadas. Propõe, ainda, uma estratégia para planejamento contingencial para esta finalidade.

Sejam bem‐vindos à SB10Brazil. Espero que as discussões levantadas durante a conferência atinjam e superem as suas expectativas como participantes, assim como as nossas expectativas, como organizadores, de contribuir e avançar no entendimento e na base de conhecimento. Em três dias de compartilhamento de visões e perspectivas, esperamos construir coletivamente uma base de conhecimento capaz de impulsionar novos avanços e efetivamente nos distanciar do plano teórico, em direção a um ambiente construído mais sustentável e adaptado às novas demandas que se apresentam.

Obrigada por participar e até breve!

Summary

The steel industry stands out for its steel slag’s recycling practices, which provide alternatives for construction material’s components. However, some limitations arise regarding the evaluation of the products and co-products’ environmental load, since there must be a coherent division of the ecological baggage inherent to the making of those products and co-products. The Life Cycle Assessment methodology represents a holistic tool for distributing environmental impacts between a product and its co-products, allowing impact allocation based on different criteria. Aiming for a better understanding of the impact allocation criteria’s influence on the LCA’s results and, therefore, on a more conscious view of the steel making process and the recycling of its slags as prime matter for construction materials, this paper intends to perform a simplified LCA (streamlined LCA) of steel and its slags, carrying out a comparative evaluation of the different results obtained from the use of allocation impact criteria based on mass properties and economic value, and, more specifically, this paper aims to analyze the difference between results obtained by using data from generic inventories and data from the company that characterizes the case study. For result treatment and interpretation, the software SimaPro 7.1 was used and the environmental impact evaluation was performed through EcoIndicator 99. The obtained results highlighted the relevance of the impact allocation criteria discussion to assess the competitive edge of steel slags against its alternatives for producing construction materials, and confirmed the importance of using specific data from a given company, sector or country for constructing representative inventories and to stimulate the definition of environmental performance indicators and goals, to promote a more sustainable growth of national steel industry.

Keywords: indicators, assessment, sustainability, buildings, sustainable construction

Summary

Sustainability indicators for buildings are needed to measure its performance and impacts, to set targets, evaluate current practices and to improve the quality of construction. In Brazil, there are several efforts to define sustainability metrics for the built environment at different scales. However, they vary greatly and are defined by criteria and methodologies not necessarily replicable. This work aims to analyze methodological procedures to develop indicators at the building level in Brazil. First, despite the lack of standardized methodologies, a group of fundamental steps for developing indicators are identified and a final analysis will be carried out to verify this process adherence in building sustainability assessment methods available in Brazil (LEED and AQUA Process). The construction sector is strategic but also generates numerous impacts that must not be ignored. To move forward to the sustainability, the construction industry needs information about its performance, trends and pressure factors. An indicator is a parameter that provides information and communicate complex phenomenon in a simplified manner, including trends and progress along the time, but, an indicator in itself is not able to promote performance enhancement. The establishment of goals and benchmarks for indicators are equally needed to evaluate and assess the progresses in sustainability matters and calibrate analysis. In a global scale, indicators development faces technical and practical limitations and involves more than only listing indicators. Building environmental assessment establishment foresees the organization of indicators in logical structures in order to conduct comparisons between – and register the improvement in – individual buildings. Brazil needs a systematic and transparent advance in indicators development to overcome challenges, specially related to key-aspects that can change focus according to cultural realities and specific priorities.

Summary

Along with the implementation process the Technical Quality Regulation of the level of Energy Efficiency of commercial, service and institutional Buildings (RTQ-C) is in development by the Brazilian Ministry of mining and Energy, the Regulation for Residential Buildings (RTQ-R).The methodology presented this paper is an evolution of the concepts presented by SOUZA and PEREIRA (2008) in the definition of the range external temperatures and solar radiation that should be the target for the dimensioning of solar shading systems. As an incentive to the use these solar shading devices in buildings in order to diminish solar loads in transparent surfaces, a bonus methodology was developed to be applied in the RTQ-R.

Summary

The Brazilian construction sector has searched new technologies and solutions for theirs processes optimization and value added products increase. In this way, the Supply Chain has reacted in this new scenario with the sustainable and Lean techniques researches. The Lean concept applications were sufficiently worked in the construction sector. Not always, it contemplates the sustainable principles, because its total focus is the waste reduction. Then, this research observed some study cases, where the sustainable concepts implantation were implemented. And they have considered the Lean principles application in construction Supply Chain. It must be observed that, in this joint application, one philosophy does not exclude another. The sustainability and Lean concepts can be worked together. Based on many authors’ researches, this paper presents a little brief of concept applications in the diverse productive stages. After this presentation, it was suggested a discussion of main barriers to “Green and Lean” implementation in some specific points of the construction Supply Chain.

Summary

AQUA (Alta Qualidade Ambiental) is a Brazilian certification method adapted from the French version HQE. The purpose of this certification is verifying the building’s compromise with sustainability and energy efficiency according to local references of buildings’ performance. Energy efficiency may contribute to achieve a higher score through the AQUA method, and it is mainly ruled by PROCEL Edifica - a local energy efficiency rating system for buildings. A group of 4 high rise towers was designed aiming the AQUA Certification at Sao Paulo, Brazil. All projects involved followed a set of requirements to fit sustainability and energy efficiency demands. A representative tower of the group was chosen to be simulated to verifying its accomplishment with the requirements of the referenced standards. Special glazing systems, automatic control of lighting sets, elevators with energy recovery systems and automatic internal shading elements were simulated through TAS software in order to comparing energy demands to a reference model. The elevators with the energy recovery system saved 37% of energy for vertical displacement’s system. Artificial lighting control system reduced energy demands by 32%. Special glazing system together with the internal shading devices helped reducing overall energy demands by 30%. The overall heat transmittance coefficient was reduced from 3.2 W/m².K to 2.1 W/m².K.

Keywords: energy-efficiency, residential sector, regulation

Summary

In Brazil the residential sector accounts for about 22.0% or 94 TWh of the electricity consumption, what increases the concern about energy savings. Stimulated by this grown on consumption and by the National Program on Conservation and Electricity Rational Use (PROCEL), the Brazilian government adopted measures such as specific regulation and technical indicators to establish energy efficiency minimum levels in new buildings. The main objective of this paper is to present the Brazilian voluntary regulation and the actual proposal to classify the energy efficiency level of residential buildings. The technical requirements to classify the energy efficiency level of residential buildings and the regulation method, which is divided into three major components, are presented. For housing units (which consists on single-family houses and apartment units), the efficiency level is obtained through the evaluation of the envelope and the water heating system. Extra score can be added through initiatives that provide extra energy efficiency. For multifamily buildings the efficiency level is obtained through the weighted average of the classification of its units and in common area of multifamily buildings the evaluation is divided into areas of frequent and of eventual use, being classified the requirements which are applicable according to the building in evaluation. The efficiency levels vary from “A” (more efficient) until “E” (less efficient). Energy efficiency classification of residential buildings through the presented regulation proposal, presents as an efficient method of energy saving that will encourage the civil construction market to invest in more energy-efficient buildings, once there is a large potential of energy saving by the residential sector. The major benefits that can be provided by the regulation are: consumers can choose more efficient buildings, owners can use it as a market strategy to promote sales, energy cost reduction during building operation and decrease on natural resources consumption.

Usually the integration between different specialties occurs late in the process, when opportunities for changes are very limited. In opposition, the Integrated Design Process (IDP) proposes the multidisciplinary work of all actors involved since the beginning of the process. Among the first steps is the discussion and definition of a consensus between client and designers regarding goals, performance targets, means, roles and responsibilities. It was proposed for a research to investigate, from two Brazilian case studies, how IDP can contribute for better environmental performance of buildings. First a theoretical reference was established, from the main references studied, consisting of the fundamental elements that characterize IDPs. This was used to guide the following research phases. The case studies, building design processes with environmental performance requirements, were investigated through interviews and design documents analysis. At the analysis phase, both cases where positioned in relation to the theoretical reference. The objective of this paper is to present the main findings of this research.

Summary

Sustainability, in discussions since Eco-Rio/92, has become an important approach in urban and regional planning. It has also become a qualifier of the socioeconomic development, which reflects the use and occupancy of land. The goal of sustainable planning is to improve the quality of life for this and for future generations. Such presuppositions, legitimates planned proposals for sustainable tourism in the Babitonga APA region, in the northern portion of Santa Catarina State in Brazil. With these proposals, it is expected to enhance, to better preserve, this ecological heritage between land and waters of the surrounding municipalities, where the activities of echo-tourism may provide greater awareness for environmental questions and allow complementary jobs and incomes to the residents. Thus, to the planning, proposals for the increasing demand of services linked to the tourism fit, but that allows to reduce environmental impacts with more sustainable alternatives to the productive diversities.

Keywords: energy, public housing, Brazil, simulation, optimization

Summary

This research examines how public housing design has been developed to attend the low income population in Sao Paulo, Brazil and how changes in the existing design affect the quality of the dwellings and energy consumption. The hypothesis of this research is that energy efficient architecture concepts applied to the current design practices of public housing in Sao Paulo reduce energy consumption in the buildings significantly. In this study, computer simulation is used to evaluate current energy performance of public housing buildings as well as to simulate the incorporation of new energy saving features into the design and assess their performance. The findings show that energy consumption can be reduced by as much as 54 percent in doing so. This, highlights the many opportunities for architects to influence the quality of the design being produced for the less fortunate population in the public housing sector in Sao Paulo, which positively impact comfort conditions within the buildings and most important, reduce energy consumption.

Summary

Concerns regarding anticipated water supply scenarios have come to the international forefront, while urban centers impermeability and climate change are resulting in more frequent and stronger storm events. Green roof technology has gained attention in the technical community due to its potential multifold contribution in mitigation of urban flooding damage, provision of alternative water source, increase in urban biodiversity and energy savings associated to thermal performance role in both indoor and outdoor environments. An ongoing research project at University of Campinas aims at assessing both thermal comfort and rainwater retention contribution of a set of green roof test cells. From a representative sample of the green roofs systems available in the Brazilian market, nine test cells were assembled as follows: four extensive green roofs cells, substrate thickness of 0.10 m (with a 2%-slope); two modular extensive green roofs cells with configurations, substrate thickness of 0.09m (with a 2%-slope); two semi-intensive cells, with substrate thickness of 0.25 m (with a 2%-slope); and one reference cell (ceramic tile roof inclined at 25%). Each test cell received a tipping bucket that registers runoff. Sequentially, a set of five rainwater collectors, a “Y” filter and a 310-liter water box for collected rainwater storage were assembled. This paper describes the experimental approach and arrangement proposed to support such evaluations. Unfolding of this research includes validation of test cells format to carry out rainwater studies and comparative analysis to an integral, full-scale, green roof. It is expected to determine the contribution of the studied green roofs to rainwater retention and pre-treatment for the region of Campinas, as well as to provide a standardized methodological approach for replication of such studies in other regions.

Summary

The Hong Kong Housing Authority (HKHA) provides affordable quality public rental housing for the low income families, which account for about 30% of the population of Hong Kong. Our housing estates are typically high-rise high density living habitats plus associated retail, carparking, community, welfare and education facilities. In order to realize the concept of sustainable development, HKHA has developed the “Integrated Procurement Approach” to integrate innovative ideas in design and production, research, wider use of mechanized building process for developing a “Green Estate”. This can achieve a holistic and environment-friendly design, in keeping with “lean construction” concept, eliminating waste and abortive work in the delivery process towards further advancements in improving productivity and built quality. With the dichotomy of innovation and conservatism, HKHA develops a brand new “Three-envelope System” for the integrated procurement mode. The “Innovations Envelope” itself is innovative, as it breaks new ground in selecting innovative proposals with itemized value-for-money consideration in life-cycle costs. It is a ground breaking procurement approach in the international arena. This “Integrated Contract” is a hybrid of design-and-build and traditional contract. It demands earlier and better integration of design and construction expertise from employers, designers, builders and manufacturers with synergistic results. This paper presents how this procurement mode has been successfully developed and executed with fruitful results in obtaining innovations from tenderers.

Summary

In recent years, the Hong Kong Housing Authority has been developing a new design strategy: adopting modular flat design for mass customization in public rental housing in Hong Kong. The Modular Flat Design (2008 Version) has been optimized to strike a better balance amongst various factors including valuable land resources, buildability and cost effectiveness and user-friendliness including responses to the findings from Residents Survey. This is a product of cumulative experiences over years. By applying modular flats to the building design in affordable social housing developments, Hong Kong Housing Authority can assure quality and cost-effectiveness while at the same time achieving consistency in standards to a certain extent. The HA plans, builds, manages and maintains different types of public housing, including rental housing estates, interim housing estates, and transit centres.

Summary

The stock of public housing estates in Hong Kong grew at a fast rate during the last 2 decades, from 566,000 flats in 1988 to 674,000 flats in 2008. The Hong Kong Housing Authority (HKHA) has shaped and re-shaped her maintenance and management strategies in this stretch of time as both her buildings and population age with time. The transformation is centred on sustainability of the estates as communities in the built environment. The focus is on people. Maintenance strategy moved from the traditional responsive mode to proactive approaches. Along the time-line are the CARE (Condition, Appraisal, Repair and Examination), Home-CARE and Total Maintenance Schemes. Estate renewal moved from the Comprehensive Redevelopment Programme to the new Long Term Housing Strategy, Comprehensive Structural Investigation Programme, Estate Improvement Programme and addition of lifts and other provisions to improve accessibility within the estates and inside the buildings. Latest technologies are introduced to reduce energy consumption and to enhance security and enjoyment of the tenants, such as lift modernization, free Wi-Fi provisions and digital CCTV surveillance systems. Provision of estate management services moved from conventional transactional mode to participative mode, with a strong educational emphasis. The Estate Management Advisory Committees, the Housing Channel, Marking Scheme for Estate Management Enforcement, and more recently the pilot projects of Housing Advisory and Service Team are rolled out as solid steps along this direction. The concept of providing shelters for the needy gradually evolved to the building of the home and a supportive community, with a package of schemes for fostering harmonious families in the estates. This paper maps the transformation, with particular reference to fostering harmonious communities, caring for people of different ages and abilities, community participation, life-cycle care of the built environment, estate rejuvenation, and contributions to a more ecologically friendly environment.

Summary

The Hong Kong Housing Authority (HA) develops and implements a public housing programme which seeks to achieve the Hong Kong Government's policy objective of meeting the housing needs of people who cannot afford private rental housing. Approximately 30% of the Hong Kong population is now living in public rental housing units. The HA plans, builds, manages and maintains different types of public housing, including rental housing estates, interim housing estates, and transit centres. In addition, the HA owns and operates some flatted factories and ancillary commercial and other non-domestic facilities. In the context of public housing development, the missions of the HA are to provide affordable quality housing and other housing related services to meet the needs of the customers in a proactive and caring manner; and to ensure cost-effective and rational use of public resources in service delivery and allocation of housing assistance in an open and equitable manner. The four core values of the Authority, viz. Caring, Customer-focused, Creative, Committed (the 4 C’s) are manifested in the continuous pursuit of improvement of the design and provision of building services installations at public housing estates to achieve enhanced cost-effectiveness, usability, reliability, maintainability, environmental friendliness and social responsibilities. This paper will focus on some of the measures that realize quality living in affordable social housing through sustainable building services design such as green lighting design; use of energy efficient building services equipment, application of renewable energy, hygienic refuse handling, hybrid ventilation as well as measures for enhancing quality of water supply and water conservation.

Summary

Transformations of building stock are essential for the development of sustainable urban areas. Mainly in those cities, such as São Paulo, where there are structural paradoxes that should be overcome. First, the quantity of high-rise buildings completely empty is astonishing, mainly in a ciy where almost 30% of the population is still underhoused. Second, the urban vertical form so widespread throughout the city is not associated with increasing demographic densities, on the contrary the districts with concentration of high-rise buildings have lost population. The formulation of an urban policy grounded in the compaction of the city and the use of the built heritage seems to be an adequate idea. The main purpose of this research is two-folds. First, it is focused on the analysis of the São Paulo previous experience on building recycling. The formulation of a set of architectural indicators enabling the process of selection of building is presented, describing the main features of the policy. Second, it is focused on researching refurbishment international technologies, under the support/infill method proposed by Habraken and the SAR 1965. The main objective of this paper is to demonstrate that the formulation of a high-rise buildings refurbishment housing policy is an unique opportunity to mobilize underused resources, restructuring the building industry as well as compacting the city through the intensification of urban land-use in central areas.

Summary

This paper presents an integrated analysis for tank volume calculation in rainwater harvesting systems based on three important variables. These variables are water demand, system efficiency and repayment time. Several simulations were carried out in different scenarios considering typical values of both catchment area (for low- and medium-income households) and water demand, with fixed water and tank costs. Results showed that the integrated analysis of demand, efficiency and repayment time may assist designers to determine a more adequate reservoir volume.

Summary

The search for sustainability in the civil construction industry (CCI) involves reducing the generation of construction and demolition waste (CDW) during the various stages of design, construction, renovation and retrofitting of a building. This measure is necessary because high rates of construction material waste are still noticed in construction sites. Therefore, this study providing data for a broader research project (dissertation) that is under development assesses construction professionals’ (civil engineers,building technicians, foreman) perception of the implementation of the National Council for the Environment (CONAMA) resolution no. 307 for managing RCD in construction sites in Vitória (Espírito Santo, Brazil). The methodology comprised literature review, photographic documentation, field research, semi-structured interviews with the staff of the construction site, transcription of interviews, and qualitative analyses of the results. The field research was carried out with nine construction companies in the city of Vitória between September 2009 and October 2009. The forms employed were made up of 35 questions, subdivided into seven themes: 1) CDW Management, 2) CDW, 3) legislation, 4) Recycled Aggregates, 5) Market, 6) Company name and 7) Identification of the respondent. Another instrument used in data collection (an observation protocol or visit record) enabled recording several observations during the field research, which were subsequently used for comparative analysis of construction companies and sites. It was found that most construction companies managed CDW ineffectively, not complying with the CONAMA Resolution 307.

Summary

One of the most striking characteristics of the contemporary urbanization process is the sprawl of the urban area over the territory, shaping spread urban nucleus disaggregated from the main urban area. The pattern of urban dispersion, as it is called, has led vegetation to be fragmented around urban areas, with negative consequences to the quality of life and urban environmental balance. The aim of this paper is to evaluate the vegetation loss taken place in the urban fringes of the metropolitan area of São Paulo from the 1980s to the present, using remote sensor techniques. The digital processing of landsat satellite sensor images will allow not only quantifying the vegetation loss in the fringes occurred in the period studied but also distinguish between the percentage of deforestation in the contiguous areas to the main urban area and in the spread urban nucleus.

Summary

Water and wastewater systems in urban areas as lifelines have direct impacts on the sustainability of our communities. Consequently, failures in water and wastewater systems in seismic prone areas affect the sustainability of urban regions. Water and wastewater system failure not only can cause direct and immediate impacts on our communities but also it is able to affect the sustainability of urban areas for a long period, due to long term damage to the wastewater reticulation network. This paper concentrates on earthquake effects on the wastewater system. Earthquake effects on the water pipeline reticulation network will also be discussed and compared to the wastewater network. Wastewater systems in three earthquake prone cities around New Zealand have been selected and earthquake effects on each part the system were assessed. This paper showed the wastewater system can be affected severely in earthquake and buried pipelines are the most vulnerable parts in water and wastewater facilities in developed urban regions.

Keywords: urban comfort, thermal simulation, urban design.

Summary

Recent researches in urban environmental comfort consider the influence of various parameters which are affected by local building codes and legislation. Such codes, when applied to heavy populated urban centers can result in decreased life quality and undesirable social and environmental problems. In this case, the consequences go from building environmental inefficiencies such as bad ventilation or inadequate use of natural lighting to consequences like increased energy consumption or health problems. In this context, this study aims to analyze the spatial configuration of the city of Juiz de Fora , Brazil , and to assess the possible impacts of a new building code proposed to the town. Methodologically, local microclimate conditions are considered and computational tools such as SketchUp (GOOGLE, 2009), CityZoom (GRAZZIOTIN, 2009) and ENVI-met® (BRUSE, 2008) are used to simulate natural lighting, ventilation and urban design resulting from different possible urban configurations. This approach allows verifying the resulting environmental comfort of the city center residents. The simulated data demonstrate that changes in typical urban parameters like street dimensions or building heights result in significant changes related to the thermal comfort of the site, which should be considered in a sustainable urban design process.

Keywords: GHG emissions; building construction, Brazil

Summary

Energy use in buildings is one of the key issues to be approached so as to face the challenge of the climate change. The construction sector accounts for approximately one third of the world emissions of greenhouse gas (GHG) related to energy, being around 80% of such third attributed to the use and maintenance phase of buildings, and the remaining 20% attributed to the construction phase. However, in order to establish rules and achieve the desired reduction of GHG emissions, it is fundamental that mitigation programs be adequate to the local setting. Based on a broad literature review, this paper assesses the calculation methods for quantifying GHG emissions and their applications in the construction sector. A social housing case study is used to illustrate such discussion in the Brazilian context. The emission sources encompassed were manufacture and transportation of building materials, energy consumed by equipment use, resources processing, disposal of construction waste, and during building operation. Given the system limits for this study, the preliminary calculation of GHG emissions showed similar results for both construction and operation phases, distinguishing the particular Brazilian context from the average international discussion. The case study also indicates the relevant aspects for measurement and proposes actions to mitigate emissions, which are: setting-up specific emission factors to regional processes, research to quantify GHG emission from various emission sources during the construction process, use and maintenance of the building to compare data, and parameters for assessment to support the selection of building materials.

Summary

The renovation of existing buildings is a theme of particular importance due to the opportunity it offers in the search of a more sustainable architecture. This paper presents the results obtained with a building renovation at the Federal University of Juiz de Fora, Brazil, in which issues of environmental comfort and energy efficiency had been focused. The main challenge was the use of climatic resources for obtaining environmental comfort with low energy consumption. To achieve this purpose, computer simulations were carried out to predict the potential performances of the building and to aid design alternative formulations. Moreover, to check the real performance of the proposed solution, temperature measurements were performed before and after its completion. The measured data were compared with that provided by the simulations leading to analyses that could verify the real performance of the ready construction, and, at the same time, validate the applied methods. This article presents the proposed design, the adopted methods, the results of the applied simulations in the sketch phase studies and finally the comparison between the expected results and those obtained after the building renovation work.

Summary

Awareness of the need to manage the water consumption in buildings, using water submetering system, has increased the demand of this system both in new buildings such as those in operation. This fact brings with it the need for training professionals of building systems. One of the reasons is because this technology requires changes related to project procedures of water supply systems, particularly in the choice of model of establishment of design flow rate. Thus, the aim of this paper is to present the guidelines of the professional training program ProAcqua. The results obtained to date has shown that professional training is improving the quality of projects, implementation and management of water use in multifamily buildings, and also in improving the quality of other technologies related to water submetering system.

Keywords: Sustainable Buildings; LEED Certification; Building Projects; Brazil

Summary

The quest for higher sustainability standards in the Civil Construction Industry is still incipient. This research aims to study the application of the LEEDTM certification to Brazilian buildings, understanding the restrictions for its use in a reality different from the original American reference, and disseminate the analyzed results of two national case studies to put the debate in perspective. Obtained results confirmed that (1) obtaining a LEEDTM certificate is not an easy task and in Brazil it means jumping from complete lack of reference to follow North American standards; and (2) even in developed civil construction centers in Brazil, the market is not yet prepared for international green certification. There are huge obstacles to be overcome but certification opens discussion on matters never approached before in Brazil. Though limited, introduction of building certification in the Brazilian market opens discussion on subjects never treated before. Certifications, voluntary schemes and other market pull instruments play a fundamental role in market transformation for sustainability, but depend on a previous foundation regarding P&D and knowledge and technology transfer. The quest for certification in itself should be avoided. Otherwise, it may put at risk the valuable contribution building certification can bring to market transformation.

Summary

The use of solar energy for water heating constitutes an important action for sustainable construction. The high initial cost of solar heating systems, however, does not encourage its use in social housing. In order to facilitate the use of this technology in social housing, low-cost solar heaters (ASBC) have been developed, which consist, in general, of simplified technologies, with the use of recyclable materials and that provide, however, a minor overheating to the water to be consumed. This study evaluates the impact of ownership of ASBC in seven social housing units located in the Núcleo Vila Brandina I, in Campinas, São Paulo, in which the solar heaters were manufactured and installed by the community involved, which participated in workshops to raise awareness of the rational use of water and energy. Among the results obtained, there is a reduction of energy consumption and a temporary increase in water consumption.

Summary

AQUA (Alta Qualidade Ambiental) is a Brazilian certification method adapted from the French version HQE. The purpose of this certification is verifying the building’s compromise with sustainability and energy efficiency according to local references of buildings’ performance. Energy efficiency may contribute to achieve a higher score through the AQUA method, and it is mainly ruled by PROCEL Edifica - a local energy efficiency rating system for buildings. A group of 4 high rise towers was designed aiming the AQUA Certification at Sao Paulo, Brazil. All projects involved followed a set of requirements to fit sustainability and energy efficiency demands. A representative tower of the group was chosen to be simulated to verifying its accomplishment with the requirements of the referenced standards. Special glazing systems, automatic control of lighting sets, elevators with energy recovery systems and automatic internal shading elements were simulated through TAS software in order to comparing energy demands to a reference model. The elevators with the energy recovery system saved 37% of energy for vertical displacement’s system. Artificial lighting control system reduced energy demands by 32%. Special glazing system together with the internal shading devices helped reducing overall energy demands by 30%. The overall heat transmittance coefficient was reduced from 3.2 W/m².K to 2.1 W/m².K.

Summary Water scarcity has become a major global problem which is to highlight the need for studies of new methods and techniques of water conservation. Among the technologies of possible water conservation in buildings, rainwater can be an alternative. The aim of this study is to evaluate the flow of rainwater collected from roofs made of three different types of materials: metals, asbestos cement and clay, located at the School of Civil Engineering, Federal University of Goias. After checking the volume of discharge correlated with evaluation of the quality of rainwater collected in each type of roof, and directly from the atmosphere, the cases were evaluated based on criteria established by the NBR 15.527 (ABNT, 2007). Both noted that the process of removing rainwater is essential to achieve the water quality in these systems, and the elimination of rain based on time was not enough to get rain water with quality guaranteed. Among the treatments, tile, metal proved to produce better quality water after discarding the first 150 L collected (corresponding to a 2 mm of rain in areas of contribution studied). However, this same volume, as suggested by NBR 15.527, were not sufficient to ensure that rainwater collected can be used without risk to users and water plumbing, which requires at least a simplified water treatment. Thus, this research also evaluates the effectiveness of a rainwater treatment system captured on the building with asbestos cement roof. The experimental system for the treatment of rainwater consists of two modules for membrane filtration of 25 microns followed by an UV disinfection unit and the other followed by a chlorine disinfection unit. The results of physical-chemical and bacteriological tests show that both methods are effective for obtaining water with a higher quality.

Summary

The accelerating depletion of non renewable resources requires a clear response from many different actors in order to reduce energy demand. As architectural projects require a significant proportion of total energy demand for thermal comfort, lighting and building operation, there is an urgent need to promote renewable energy sources and reduce total energy demand, in new buildings and the re-conditioning of existing building, in order to reduce dependence on fossil fuels. The study of thermal performance and natural lighting in buildings requires an evaluation of the external climatic conditions in order to achieve improvements in indoor environmental conditions, a reduction of energy dependence and external environmental impacts, especially though reduced use of artificial conditioning. Using physical and virtual simulations, this paper evaluates thermal and lighting performance and assesses the contribution of the bioclimatic design resources with guidelines and strategies to improve the behavior of the similar spaces exposed to different orientations, with a case study of modifications of an isolated building in the City of Buenos Aires. The study presents the methodology used to analyze and compare conditions in identical modules with different orientations, and the resulting modifications in the same modules, to improve an existing building with problems of comfort and energy demand. The results provide comparative information on the contribution of design to achieve this aim. The design and integration of a new renewable energy installations in the same facades is also evaluated to quantify the energy generated, compared with the energy saved using bioclimatic design resources, as well as the reduction in environmental impacts. This study demonstrates that creative architectural responses can optimize the use of natural resources, to reduce energy demand through a combination of the use of renewable energy systems and reduction in energy demand for artificial conditioning.

Summary

Waldorf education is based on the research into child development conducted by Austrian educator and philosopher Rudolf Steiner. Central to the philosophical beliefs of Rudolf Steiner is that each person consists of a body, soul and spirit. His overall body of work is called "Anthroposophy" or "wisdom of the human being”. Waldorf schools are examples of architectonic constructions which take into account a relation between built environment and human learning. Nature is one of the key elements bridging and maintaining such a relationship. Everything in the children’s environment is made of natural materials (wood, wool, and silk, for example) so that the children are surrounded by many beautiful textures and forms. One of the main goals of Waldorf School is to protect as much of the natural environment as possible. This paper has focused in two master’s theses to evaluate how built environments influence the Waldorf pedagogic approach as a participatory element of the learning process. Qualitative analyses within a typical Waldorf building were pursued to establish the main aspects concerning learning and learning-building correlation. As a result, we have achieved insights into types of renewable systems and natural materials which greatly improve the children responsibilities with respect to preservation and ethical principles.

Summary

Sustainable development of buildings and other construction works brings about the required performance and functionality with minimum adverse environmental impact, while encouraging improvements in economic and social (and cultural) aspects at local, regional and global levels. Assessment methods provide a common and verifiable set of criteria and targets to enable measurement, demonstration and evaluation of performance of buildings, which can contribute to the formulation of procurement and/or improvement strategies and prioritization. The AQUA Process, High Environmental Quality, part of the principle that for a building to be certified, it must achieve the desired level of environmental performance, and must also follow the correct management process, in planning, organization, conduct and control. This article documents the history of the technical references for building environmental certification AQUA Process, which are an adaptation to Brazil of the French standard NF Démarche HQE®. At the same time, it presents an analysis of the structure of issues used to evaluate a project. The method used for this propose, was interviews with some of the AQUA Process creators, and the analysis of the international standards for building environmental assessment, such as: some from ISO and CEN standards, and reports of SBAlliance’s and UNEP’s. The analysis of this standards were done trying to identify as much the French and Brazilian standards agree with them and some relevant changes to be made. The results are the AQUA Process and the NF Démarche HQE®’s history, and a critical evaluation of their assessment structure.

Summary

This article describes the adoption the “double marginal” model as a valid urban highway construction solution in Brazilian cities, using both river banks and its floodplains. Although the model had already been widely spread out by nineteenth-century urban sanitation, and not only in Brazil, should not be ruled out that was the case in São Paulo, with its two along-river highways icons (Marginal Tiete and Marginal Pinheiros), which busted its use by other municipalities. Even after the model had been identified as failed, and after the administration of Mayor Quadros, in 1986, had commissioned the controversial redevelopment plan for the Tiete River proposed by Oscar Niemeyer, there are many following examples of this type of along-river roads that were built in other Brazilian cities (Pinho, 1999). Part of the discussion is based on cultural aspects of land management and urban planning, typical of Brazilian urbanization patterns and its relationship with rivers, dating back from the colonial period. Noting that there are, especially in other countries, implementation of highways along the rivers that do not confine them completely, opting for the use of only one bank, this article seeks to understand the reasons for the adoption of the double marginal morphology as default. It adds to the discussion the spread of the concepts of green structures in urban design (Benedict and McMahon, 2002). Faced with these new concepts, the work calls into question not only the incongruity of the design matrix of the double marginal avenues of Sao Paulo, but its generalization. It criticizes the model as a false advantageous and easy solution for Brazilian cities, which bypasses the search for more sustainable solutions and urban design approaches that are symbiotic with their rivers and respective floodplains.

Summary

One ton of wood means 1.4 tons of carbon dioxide absorbed by trees. When mature trees are cut down from forests a great portion of their wood is employed as building material. Using sustainably harvested wood as a construction material is a simple and cost-effective way to help fight climate change. Carbon dioxide remains stored in wood until wood products decay or burnings release it back to the atmosphere. Substituting a cubic metre of wood for other construction materials (concrete, blocks or bricks) results in the significant average of 0.75 to 1 ton CO2 savings. Conscious using and standard techniques for building-with-wood are worth adopting to reduce greenhouse gases emissions. Moreover, wood is a warm and comforting material that provides a tangible connection to nature and the outdoors. For many architects and builders, wood offers an added aesthetic appeal that no other material can provide. This paper aims at (i) giving theoretical background on the creative use of wood as building material; and (ii) analyze deployable wooden structures, a class of problems which involves interdisciplinary aspects from architecture to design and production engineering. Results have exploited current technological resources and came up with the wealth of applications of wood into building construction.

Summary

This paper presents the methodology and associated results of a survey aimed at evaluating indicators of sustainable management for high-rise construction sites. The survey was conducted across 45 sites belonging to 35 civil construction companies currently operating in the Recife Metropolitan Area (RMR). The main objective of this paper is to discuss a methodology for assessing the engagement of worksite management with environmentally sustainable practices, aiming to uncover the engineers’ degree of familiarity with technologies that are able to promote more sustainable construction methods and to analyze how the integration between the constructive and managerial processes interfere in the adoption of socially and environmentally responsible construction methods as adapted to Brazil’s regional realities. The current lack of knowledge surrounding the influence that adopting socio-environmentally responsible actions has (which, in many cases are relatively simple to perform) in improving the productivity of employees on sites and overall organizational performance via impacts on financial profits provides justification for such a study to be conducted. The choice of indicators variables used for this assessment is based on a literature review of evaluation systems and managerial processes that influence sustainability, along with scientific papers available on the subject. Following the analysis, these indicators variables are categorized into the following groups: materials, water / sewage, energy, labor, safety and quality of life at work, management of the building site, waste, machinery and equipment, construction site sustainable aspects and the building site’s relationship with its surroundings. Based on the opinion of the engineers studied, it is concluded that waste management is the activity most significant for sustainable management and effective solutions to waste generation is considered the greatest difficulty on building sites. The survey also highlights the influence of the Ministry of Labor Regulations in the management of building sites.

Summary

For a conceivable time an assessment of buildings in terms of their sustainable construction will be based only on international consistent methods. Coming from today’s standard it is shown what kind of international basement is needed to develop future building certifications and what steps are necessary to implement the required systematization. The ambition is a unitary certification system, which could be adapted worldwide by a harmonized method, independent from regional specifications. After developing an integral catalogue of criteria and structuring the upcoming system, the generally applicable types of methods are to be estimated. Aside from adapting the values to regional circumstances the needed enhancements of the system are seen as a part of a global strategy to keep those basic conditions which are vital for mankind. Presenting these ideas will simultaneously show the orientation of the German Green Building certificates, developed by the German Government and DGNB and explain the fundamental approach to the beginnings of its international orientation.

Summary

Tools to assist those involved in the task of designing allies are needed to fit the project to the environment. This paper presents the initial results of a group of tests for the development of experiments and materials for display in the wind tunnel. The experiments developed enable the understanding of the wind patterns in architectural and urban spaces, and to identify areas more or less ventilated, which also indicates the possible formation of heat islands. They allow designers to recognize their ability to interfere in the dynamics of wind, often through simple changes, which may result in substantial gains in environmental comfort. Architectural and urban models and models of equipment have been developed for use in the experiments. The tests were carried out in the wind tunnel of the School of Architectural and Urbanism of the Federal University of Rio de Janeiro - FAU/UFRJ, using three techniques of visualization, wool-yarn, ribbons and windblown sand.

Summary

In Latin America, the phenomenon of urbanization is well known, since it is already deeply stressed both large cities and in the medium-sized urban centers and even in small towns. It is assumed that this process is opposed to the actions envisaged in the plans and programs designed to promote sustainable urban development and, consequently, require water utilities water resources increasingly affecting many ecosystems that support them. In this study, in particular, are noted indicators showing values and effects of this inconvenience. The purpose of this study was to construct a system of indicators and criteria on the basis of the principles of Sustainable Development (SD) to model water resource management as an inevitable element to supply potable water, sewerage and sanitation services (PWSSS) in the city of Culiacan, was made in view of the importance of water resources represented as essential input for the activities of an urban society which is said to be a progressive and modern one. Here they are presented twenty-four indicators organized into three categories based on the vision of economic, social and environmental sustainability. Finally, we established a set of conclusions on the theoretical and methodological discourse to construct the valuation model of urban water. With this approach, no doubt the institution in charge would move towards a sustainable management of water resources in the city of Culiacan.

Summary

In low income communities in developing communities globally, people who are struggling to survive are motivated to create innovative resource-efficient solutions. Unfortunately, these people do not usually have adequate resources to sustain a desired quality of life. Observations conducted by the authors, from the Pontifical Catholic University of Rio Grande do Sul (PUCRS) in Brazil, and from Ball State University (BSU) in the United States, show that an strategy that integrates planning, designing, construction, community participation, monitoring of the use of spaces, and generation of income might help these communities to afford and maintain their housing areas in good conditions. This paper speaks to these observations, especially those in the Vila Nossa Senhora de Fátima, in Porto Alegre, Brazil. These observations were conducted in classes led by the authors as part of two exchange consortia they coordinate at their home institutions: the U.S. Brazil Sustainability Consortium (USBSC) and the U.S.-Brazil Universities of the Future Consortium (USBUFC). The paper also compares these observations in Brazil to observations made in similar communities in Mexico, where one of the authors leads the U.S. side of a third allied consortium: the North American Sustainability, Housing and Community Consortium (NASHCC). This paper also speaks to the imperitive of investing in the education of potential social leaders, not only in these communities, but also in broader society. This investment is seen by the authors as essential in helping to build the new generation of leaders within the social housing areas that are needed to facilitate and sustain improvements in these communities and in resident quality of life.

Summary

This paper presents a summary of the advances achieved in the qualification, evaluation and certification of sustainable buildings in different fields of action in Argentina, demonstrating the increasing concern for the performance of the built environment in the framework of Sustainable Building, as well as the difficulties of achieving a consensus in a common framework. In the development of new national standards, two areas of advances are being developed; the preparation of new standards of ‘Sustainable Construction’, based on ISO standards, that define a conceptual framework for the development of certification, and the recently approved standard for the labeling of ‘Energy Efficiency of Building Envelopes’ promoted by the Secretary of State for Energy. The activities of Government Agencies and Non Governmental Organizations in this and other fields are presented. Another area of activity is the training and orientation of specialists and concerned professionals through workshops, courses for continuing professional education, academic courses and research. Despite the lack of national or local regulations to achieve efficient use of energy resources, especially in the building sector, there is an increasing demand generated by developers and investors aiming to achieve value added for projects offered in a competitive real estate market and companies implementing programmes of corporate responsibility in the field of environmental protection. This paper presents the development of new standards, professional training courses and demonstration projects that aim to certify the environmental sustainability. The results are evaluated and the conclusions propose different lines of future action based on local requirements and the experience of the different activities summarized in the paper.

Summary

Putting the principles of sustainability into practice within social and economic development requires intensive involvement and participation of the construction, real estate and finance industries. It is necessary that design, construction and refurbishment of buildings are aligned with targets in energy-efficiency, resource preservation, climate change and human health. On the one hand design strategies, design tools and construction techniques need further development, but the demand for sustainable buildings needs to increase also. For a long time market acceptance, market penetration and market transformation of sustainable buildings has been hampered by various obstacles and prejudices. This is now changing because of prove that sustainable buildings have economic advantages, because of social and environmental responsibility being increasingly accepted by all stakeholders, due to developments in law and standardisation as well as due to the example set by the public sector. The vicious circle of blame for low demand for sustainable buildings can therefore be broken. Positive change in the built environment can be brought about by various instruments (laws, standards, grant programmes, market stimulation programmes etc.) as wells as by creating connections between individual and institutional objectives with sustainable development objectives. For those investors interested in sustainable investments, sustainable real estate funds, green REITs can be offered as new investment alternatives. However, it is equally important to pay greater attention to the social and cultural importance of buildings. Topics such as the interdependence between buildings and life style choices and consumption patterns of building users, the role of buildings within a neighbourhood and urban development, the need to provide adequate accommodation and to create and preserve jobs can also contribute to greater demand for sustainable buildings.

Summary

Comparative analyses among different structural systems for selected building typologies, in which it is possible to choose the best alternatives from a life cycle-based environmental perspective have been presented in literature. Besides basic life cycle analysis - LCA - and some combined LCA models, indicators like Factor X, a goal for cutting down consumption of natural resources, and MIPS, material input per unit of service, were developed to assist such evaluations. This study aims to start the discussion on potential multidimensional indicators that combine functional, environmental and economic performance and to foresee research opportunities for eco-efficiency analysis of structural frames alternatives. For that purpose, the following approaches are considered: (1) LCA, isolated or associated to other models, and MIPS to determine the environmental load; and (2) Factor X to describe environmental load reduction goals of buildings structural systems. Though LCA associated to impact weighting methods and life cycle costing provides a broader analytical and comparative basis, the limited inventory data available poses restrictions to its generalized use. While this obstacle is not overcome, simplified LCA and MIPS appear to be appropriate alternatives. All these approaches suggest the importance of having indicators able to describe functional, environmental and economic performance. A preliminary set of potential indicators is proposed for discussion. As international databases cannot be directly applied in the Brazilian context without previous validation, a careful analysis of indicators and benchmarks for structural frames alternatives should be developed - based upon national data gathering and validation, as well as cross-national comparison supported by case studies.

Summary

This paper presents an investigation of the program for water conservation and its rational use in new buildings (also known as PURAE), in the city of Curitiba, state of Parana, southern Brazil. The program, launched under municipal bylaw Nº 10.785/2003 and the municipal decrees Nº 293/2006 and 212/2007, mandates that all new buildings in the city of Curitiba include rainwater harvesting systems for non-potable uses, as well as water-saving devices. For commercial and industrial buildings of over 5000 m2 of floor area, wastewater should be collected, treated and reused. In order to evaluate the effectiveness of PURAE, the history of its implementation since 2003 was researched, and interviews were conducted in 2008 and 2010 with the city hall employees responsible for delivering the permits for new constructions. The results indicated that the program is important to the city but improvement is needed in order to meet its goals. To optimize PURAE more discussion is needed between the private and public sectors, as well as with academia, in order to clarify the program’s objectives and to mitigate some of the technical difficulties the professionals are finding. With permanent monitoring and disclosure of its performance, the program will have a better chance of achieving its targets of motivating and implementing water conservation strategies in the city of Curitiba.

Summary

At the confluence of the Marne and the Seine, at the gates of Paris and the up-river territory of the Seine, Ivry Confluences is a site where much is at stake as it is the focus of a large-scale project as far-reaching as the metropolis itself. It involves as much as a fifth of the community territory that is currently hemmed in between the Seine and the railway lines of the Austerlitz train station. It is an area that needs to be developed, made denser and linked to the rest of the city of Paris. Up until the 19th century, Ivry-sur-Seine was a small agricultural community but soon took on the scale of an industrial city by multiplying its population thirteen times in 50 years (1806 - 1856). Immediate access to the Seine, coupled with the arrival of the railway suddenly made Ivry-sur-Seine a strategic sector for development where numerous industries sprang up.

Summary This document and all of the research and tests that were made are results of an academic exercise of the Énfasis I: Proyecto Tecnológico course, from the architecture falculty of Universidad Nacional de Colombia. In this case the subject that we studied was natural ventilation, the objetive of the exercise was to answer to the question: what is the relationship between the distance of two towers in tree different positions, and the resulting ventilated area of a wind that passes between the towers back into public space? Through tests in the wind tunnel were collected a series of data that allowed us to find a relationship between the spatial arrangement of the towers and the distance of the ventilated area, these items helped us to find conclusions that help to get good design strategies of urban spaces with similar conditions. Within the contents of the report includes different possibilities of spatial distribution of the two towers and an analysis of the wind shadow within certain time ranges in order to reach the proportions and relationship between the lengths of the ventilated area.
