Sustainable Construction Strategies – Case study in Architecture Project Conception Ayres, J. Universidade Federal de Minas Gerais ‐ UFMG (email: juayres@yahoo.com.br) Cesar, C.G. Centro Federal de Educação Tecnológica de Minas Gerais ‐CEFET‐MG (email: cristinagc@civil.cefetmg.br) Abstract This paper proposes a study of project strategies for sustainable construction. A case study was made about an architectural project under development, in order to implement already at project conception, sustainable practices and thus contribute in fact for architectural result and better environmental performance of the set. However, were found difficulties in reconciling issue aesthetics and technology, but in the end, project has achieved a good compliance level, considering aspects such as maintenance and building infrastructure. Keywords: sustainable construction, project strategies, sustainability 1
1. Methodology This paper proposes an architectural project that utilizes technology and building systems for low environmental impact; efficient use on energy, water and natural resources; and that fosters comfort to users. The methodology constitutes a case study because it investigates a contemporary phenomenon within a context that approximates to reality. This work is structured based on: literature review about sustainability and construction; presenting programs for energy efficiency in Brazil; studying technologies and building systems and their applicability; architectural project development; and final result analysis. 2. Sustainability and civil construction The sustainable development concept resulted from concerns’ evolution arising in the 70's with energy crisis. This term was defined in 1987 at Our Common Future Report of The Brundtland Commission as a development that meets present needs without compromising future generations’ ability to meet their own needs. Sustainable development does not exhaust resources for the future. This concept applied in civil construction gives rise to terms such as sustainable construction, ecoefficiency and sustainable architecture. Sustainable buildings must include efficient natural resources use at the same time it provides comfort to users. Some features are desired in such projects, like: energy efficiency; hygrothermal, light, visual and acoustic comfort; concerns about surrounding environment and existing buildings renovation; use flexibility; low environmental impact materials; energy consumption control systems; renewable energy; water reuse; and low maintenance. From the 1990's, many countries have developed mechanisms for assessing environmental buildings performance through a voluntary certification process, but emphasizing aspects which represent the most challenging environmental conditions. Nowadays, each European country, besides United States, Canada, Australia, Japan and Hong Kong, has a building assessment certification system. Most of them are based on performance indicators which assign a technical score according to service level requirements for building, climate and environment, focusing on building inside, its surrounding and its relation with the city. However, according to Silva (2003), the main international assessment systems focus exclusively on sustainability environmental dimension. In Brazil’s case it must go from environmental assessment to buildings sustainability assessment and also address social and economic aspects related to production, operation and change on built environment. However, concepts about building environmental performance are not disseminated throughout Brazilian society. Although some specific sectors are mobilized to this end, the demand for environmental certification properties is now relate to specific kind of consumers, especially high standard and commercial buildings. Despite Brazil presents several initiatives on regulations and laws about this subject, the country is at the beginning of pursuit for better building environmental performance. 2
