A preocupação com o esgotamento dos recursos naturais e a conscientização sobre as questões ligadas à sustentabilidade provocaram o estudo em um setor que tem sido apontado como de grande importância para a transformação do meio ambiente: a construção civil. Com isso percebemos o surgimento de um conjunto de práticas e procedimentos visando as chamadas "construções sustentáveis", que introduziram uma nova realidade comercial no segmento da construção civil. Para avaliar se uma construção é ou não sustentável surgiram os eco-labellings, que através de sistema de pontuação ou conceitos permitem avaliar qualitativamente em que grau de sustentabilidade uma edificação encontra-se. Em especial, o mercado brasileiro vem, desde 2004, buscando a certificação ambiental LEED; sendo assim, a presente dissertação tem como objetivo identificar, após quase uma década desde a primeira submissão de projeto brasileiro ao USGBC, quais ainda são as dificuldades enfrentadas no processo de certificação LEED. O referencial teórico reforçou que o segmento da construção civil contribui de duas formas para a degradação do meio ambiente: no consumo de recursos naturais e energéticos, e na geração de grande quantidade de resíduos. Por esse motivo...

Publicado em "Vernacular heritage and earthen architecture : contributions for sustainable development", ISBN 978-1-138-00083-4; Vernacular architecture embodies a plurality of constraints from places where it belongs, in which the use of local materials and techniques is one of the main features. When compared with industrially-produced materials, vernacular materials have low environmental impacts, being an alternative for sustainable construction. The increasing use of new industrially-produced and standardized materials led to the homog-enization of the different used construction approaches, and spawned a universal architecture that in many cases is out of the environment context and is very dependent on energy and other resources. This paper ad-dresses the relation between Portuguese vernacular architecture and locally sourced materials, relating them with the territory lithology, agricultural crops and the climate. To assess the contribution of these materials for sustainability, a comparison with industrial materials at level of environmental indicators was established. This paper highlights the advantages of using local materials and techniques as a factor of local socio-economic development.

The use of local materials and techniques is one of the main features from vernacular architecture. When compared with industrially-produced materials, vernacular materials have low environmental impacts, being an alternative for sustainable building. However, industrialization have brought new standardized materials that led to the homogenization of the different building approaches and spawned a universal architecture often with no context concerns and with significant environmental impacts. As for sustainability, vernacular materials have potential to evolve and to be adapted to contemporary needs, helping to reduce the embodied energy and environmental impacts. Therefore, this paper addresses potential advantages of using local materials and techniques in the Portuguese context. Moreover, this paper establishes a comparison between vernacular and industrially-produced at level of environmental indicators (embodied energy and global warming potencial).

Sustainable building is a concept that began its development nearly two decades ago. With sustainable buildings, it is intended to establish building practices that allow minimizing the buildings impacts, build and manage buildings with an adequate balance between environment, society and economy. However, besides the importance of this concept, its broader implementation is not yet a reality. Several studies have been developed with the goal of understand the reason of these weak implementation. They have concluded that one of the main reasons is because the building stakeholders still consider sustainable practices more expensive, although several studies state the contrary. In order to potentiate the implementation of these practices, a work will be developed in order to perform a cost-benefit analysis of sustainable construction solutions. In order to perform this work, it was necessary, in an initial stage, to define the key indicators that should be considered in order to assess the main aspects of sustainable construction. This paper intends to present the analysis that was performed in order to select these indicators.

This research has the goal of determining, comparing and substantiating the actual outcome of using sustainable practices, from a financial and environmental comfort point of view. The selected context was of interest due to the challenge of quality sustainable construction at controlled costs, meant for inhabitants of the Portuguese cooperative housing, due to its economical implications and especially its social ones. Two case studies of cooperative housing developments built in Portugal are presented, the first with characteristics of traditional construction and the second including sustainable building features. With these examples, it is intended to demonstrate that it is possible to build below cost limits imposed by law in order to substantially reduce energy consumption costs for heating and cooling as well as for domestic water heating. So, calculations of energy savings in indoor heating and cooling, as well as for domestic water heating are presented in this article for two specific situations: first, for a standard comfort use of housing, as opposed to a situation of real consumption of housing developments as obtained by monitoring carried out for one year in the same dwellings studied for standard comfort. The causes that lead to a substantial decrease in energy consumption in the building of sustainable construction are also described...

As it has been observed along the years, the unsustainability of the built environment is due to the high resources consumption and low indoor air quality of the existing building stock. In order to support the sustainable refurbishment design of buildings, and to meet European goal to achieve nearly zero-energy consumption standards in buildings in 2020, it is urgent to define guidelines that can be implemented since the earlier stages of the design. This paper defines guidelines to optimize the sustainability of a residential building and presents the process of sustainable building refurbishment, applied to a case study. To achieve this goal, the definition and evaluation of a group of procedures to be implemented, and a cost-benefit analysis applied to a case study was performed.

Construction projects are complex endeavors that require the involvement of different professional disciplines in order to meet various project objectives that are often conflicting. The level of complexity and the multi-objective nature of construction projects lend themselves to collaborative design and construction such as integrated project delivery (IPD), in which relevant disciplines work together during project conception, design and construction. Traditionally, the main objectives of construction projects have been to build in the least amount of time with the lowest cost possible, thus the inherent and well-established relationship between cost and time has been the focus of many studies. The importance of being able to effectively model relationships among multiple objectives in building construction has been emphasized in a wide range of research. In general, the trade-off relationship between time and cost is well understood and there is ample research on the subject. However, despite sustainable building designs, relationships between time and environmental impact, as well as cost and environmental impact, have not been fully investigated. The objectives of this research were mainly to analyze and identify relationships of time...

To achieve the goal of sustainable development, the building energy system was evaluated from both the first and second law of thermodynamics point of view. The relationship between exergy destruction and sustainable development were discussed at first, followed by the description of the resource abundance model, the life cycle analysis model and the economic investment effectiveness model. By combining the forgoing models, a new sustainable index was proposed. Several green building case studies in U.S. and China were presented. The influences of building function, geographic location, climate pattern, the regional energy structure, and the technology improvement potential of renewable energy in the future were discussed. The building’s envelope, HVAC system, on-site renewable energy system life cycle analysis from energy, exergy, environmental and economic perspective were compared. It was found that climate pattern had a dramatic influence on the life cycle investment effectiveness of the building envelope. The building HVAC system energy performance was much better than its exergy performance. To further increase the exergy efficiency, renewable energy rather than fossil fuel should be used as the primary energy. A building life cycle cost and exergy consumption regression model was set up. The optimal building insulation level could be affected by either cost minimization or exergy consumption minimization approach. The exergy approach would cause better insulation than cost approach. The influence of energy price on the system selection strategy was discussed. Two photovoltaics (PV) systems – stand alone and grid tied system were compared by the life cycle assessment method. The superiority of the latter one was quite obvious. The analysis also showed that during its life span PV technology was less attractive economically because the electricity price in U.S. and China did not fully reflect the environmental burden associated with it. However if future energy price surges and PV system cost reductions were considered...

In many developed countries, sustainable building assessment (SBA) methods have emerged as accepted mechanisms to address the issues of sustainability in the construction industry, whereas in developing countries, this is still a relatively new concept. This paper outlines the importance of assessing the sustainability attributes of the built environment towards achieving sustainability in Malaysian building industry. The meaning of sustainable development is first discussed in order to understand its key components. Existing SBA methods, originating from developed countries, are then discussed with particular attention to outlining the problems of their direct adoption in developing countries. The paper concludes with the discussion of the rationale for proposing a SBA framework relevant and appropriate for the Malaysian context.; Zalina Shari, Veronica Soebarto and Terence Williamson

In Malaysia there is both top-down and bottom-up pressure to deliver a sustainable built environment. However, most new projects display few sustainability features, explaining the continuous presence of, and increasing problems related to, the environment in Malaysia. This paper presents nine categories of barriers and four categories of measures to overcome the barriers and to promote sustainable building practices, drawn from qualitative research undertaken with thirty Malaysian building stakeholders via in-depth, semi-structured interviews. The primary barriers that were identified by the stakeholders are: 1) a lack of expressed interest in the clients’ requirements; 2) a lack of political will, legislation and enforcement; 3) a lack of technical understanding among project team members; 4) a lack of consideration of sustainability measures by project team members; and 5) real and perceived costs. Whilst measures suggested by the stakeholders are related to the government and regulatory stakeholders, research and education sector, private sector, and clients of the construction industry. The paper concludes that regional characteristics need to be reflected in any sustainability assessment methodologies in order to encourage sustainable development locally.; http://frsb.upm.edu.my/alamcipta/index.php/alamcipta/article/view/32; Shari...

Environmental sustainability in regards to infrastructure and the built environment is a significant consideration for the Department of National Defence (DND). As the 2nd largest landowner in Canada, the DND is making great efforts to operate in a sustainable manner through the creation and implementation of sustainable building policies. Meeting the green/sustainable buildings requirements of the recent Federal Sustainable Development Strategy, and the 2006 DND Sustainable Development Strategy to achieve accreditation within generic green building systems, has proven to be extremely challenging given the mandate and the nature of Canadian Forces (CF) operations, both domestically and overseas. This line of research was conducted in order to identify the unique requirements and the sustainability factors/criteria that are applicable to the CF / DND and to investigate how to best align these requirements within the context of sustainable development strategies. Input data was obtained through an analysis of literature and relevant documents, as well as a series of interviews with individuals at all levels within the Federal Government. The result of this research undertaking was, in part, the creation of a Sustainable Development for DND based on a thorough...

Traditionally, societies use to design their built environment in a way that was in line with the climate and the geographical location that they evolved in, thereby supporting sustainable lifestyles (i.e. thick walls with small windows in cold climates). With the industrial revolution and the heavy use and reliance on cheap fossil fuels, it can be argued that the built environment has become more focused on aesthetics and cost savings rather than on true sustainability. This, in turn, has led to energy intensive practices associated with the construction of homes, buildings, cities and megalopolises. Environmental concerns with regards to the future have pushed people, entities and industries to search for ways to decrease human’s energy dependency and/or to supply the demand in ways that are deemed sustainable. Efforts to address this concern with respect to the built environment were translated into ‘green buildings’, sustainable building technologies and high performance buildings that can be rated and/or licensed by selected certifying bodies with varying metrics of building construction and performance. The growing number of such systems has brought real concerns: Do certified sustainable buildings really achieve the level of sustainability (i.e. performance) they were intended to? For the purpose of this study...

Para se obter uma construção sustentável é necessária atenção especial à fase de concepção de projetos, uma vez que esta dará as diretrizes para a execução, operação e manutenção da edificação. Os projetistas desempenham papel fundamental na concepção dos princípios de sustentabilidade dos edifícios e, o projeto deve ser orientado desde o início a esse objetivo, ajudando a modificar toda a cadeia produtiva do ambiente construído. No Brasil, em geral, há uma inércia para a elaboração de projetos sustentáveis, e apesar de existirem profissionais engajados em movimentos ambientalistas, é muito incipiente. Assim, torna-se urgente a incorporação das novas demandas ambientais ao processo de projeto. Dessa forma, nesta pesquisa se propõe investigar a respeito da concepção de projetos habitacionais sustentáveis. A temática central dessa proposta está voltada para a realização de um estudo sobre as dificuldades enfrentadas no processo de projeto de edifícios habitacionais certificados, especificamente com relação à Categoria 1 do Referencial Técnico da Certificação AQUA, objeto de estudo deste trabalho. Neste contexto, busca-se compreender a percepção dos profissionais quanto à aplicação dos requisitos de sustentabilidade no projeto de edifícios habitacionais...

The Ocean Science Teaching Center (OSTC) at the Duke University Marine Laboratory (DUML) in Beaufort, NC will demonstrate the feasibility of sustainable architecture in-coastal North Carolina. In the early 1990s, Dr. Joe Ramus proposed building an additional lecture hall to alleviate the stress that increased enrollment and technical demands had placed on DUML's teaching spaces. Designed according to the most recent version of the US Green Building Council's LEED rating system, this gold labeled Leadership in Energy and Environmental Design new commercial construction will serve as a benchmark for future sustainable construction at the Marine Lab. The US Green Building Council forms a national consensus for sustainable building, design, and maintenance standards. The LEED rating systems create frameworks for measuring progress, assessing building performance, and tracking building goals. The LEED rating system for new commercial constructions and major renovations is broken down into six sections: sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor environmental air quality, and innovation in design. While constructing LEED certified buildings requires more time and money, each new construction makes the process less expensive and less time consuming. The Ocean Science Teaching Center will serve as an example of sustainable architecture on the North Carolina coast...
