UNICAMP -Faculdade de Engenharia Civil, Arquitetura e Urbanismo.The concern with life on the planet and with quality of life has emerged as a major focus of government, media and academic communities. However, in the Civil Construction Industry, this movement is still incipient. This research has a general objective to contribute for the understanding of the application of the North-American environmental building certification Leadership in Energy and Environmental Design -LEED and of the concept of life cycle costing to sustainable buildings in Brazil. Therefore, two specific goals were envisioned: (1) study the application of the LEED certification to Brazilian buildings, understanding the restrictions for its use in a reality different from the original American reference; and (2) get the perception and understanding related to sustainable buildings and the costs during the building life cycle, using a relevant sample of the Brazilian construction market. After a detailed literature review, implementation of the certification system in the Brazilian context was analyzed on an item by item basis, and compared with the evidences obtained from the American results. Finally, two national case studies were analyzed to put the debate in perspective. Obtained results confirmed that (1) the perception that such buildings in Brazil have higher initial costs is correct, however, such perception is based on intuition rather than on specific knowledge or historical evidence; (2) obtaining a LEED certificate is not an easy task and in Brazil it means, most of the time, jumping from complete lack of reference to follow North American standards; and (3) 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 until green buildings are developed at the same time and cost efficiency of a conventional one. Even within these limitations, certification brings a new way of looking at civil construction impacts and opens discussion on matters never approached before in Brazil. 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.

Sustainability Best Practices in Small Construction Companies: Analysis Construction Companies from Ceará, Brazil

“…In the business field, this concept has been translated from the tripod of sustainability, encompassing environmental, social and economic perspectives (Elkington, 1999). Its operationalization has been sought in several economic sectors, in the face of the growing demand of society for sustainable products and services (Pardini, 2009), which is also perceived in the construction sector.…”

A ausência de Selos de Sustentabilidade em Condomínios residências e a busca pelos Objetivos de Desenvolvimento Sustentável (ODS) em Belém/PA e Região Metropolitana de Belém (RMB)

“…No que se refere à presença desses selos na região, após as buscas em diretórios das certificações, foi constatado a ausência dessas certificações ambientais na capital paraense e demais cidades que compõe Região Metropolitana de Belém. Tal ausência revela o quanto a região não tem se preocupado e preparado nesse sentido, ao menos não no que se refere à edifícios habitacionais, porque há edificações que possuem o selo LEED, contudo, sua finalidade é comercial Pardini (2009). afirmou que muitas empresas não tinham conhecimentos sobre as construções verdes (construções com selos) o que é confirmado na região o que é confirmado após a aplicação do questionário, conforme apresentado na figura 3, e muito menos os clientes sabem os benefícios que possuem essas construções, fazendo com que não sejam esperadas boas demandas no mercado, contudo, se for explicado de maneira clara a eles esses benefícios, essa demanda pode aumentar.…”
