Certificação ambiental de habitações: comparação entre LEED for Homes, Processo Aqua e Selo Casa Azul

Visando incentivar mudancas no setor da construcao civil para adequacao as agendas de sustentabilidade, foram desenvolvidos, em varios paises, sistemas de certificacao ambiental de edificacoes. Voltadas principalmente para questoes relativas ao consumo de recursos naturais e impactos ao meio ambiente; essas ferramentas tambem sao denominadas selos verdes para edificios. Com o intuito de identificar a certificacao de melhor desempenho a ser utilizada para edificacoes residenciais no Brasil, usou-se uma analise comparativa. Foram selecionados tres sistemas de certificacao, por se tratarem dos mais usuais no pais, sendo eles o LEED for Homes, o Processo AQUA e o Selo Casa Azul. Para a investigacao utilizou-se da ferramenta Analise Hierarquica (Analytic Hierarchic Process, AHP), que permite a avaliacao de multiplos criterios, com dados que podem ser tanto qualitativos como quantitativos. Este estudo demonstrou que o selo desenvolvido para a realidade brasileira, Selo Casa Azul, tem melhor desempenho para avaliar as edificacoes habitacionais do pais.

A disciplina de sustentabilidade no ambiente construído: estudo de caso na UFPR

Education plays a key role in the awareness of professionals to build a more sustainable future and gives opportunity to discuss theoretical proposals and practices related to the theme.Investment in training of undergraduate and graduate students is a direct and efficient way to achieve this goal.This paper aims to describe the methodology of teaching the discipline of Sustainability in Built Environment,tothe post Graduate Civil Construction Engineering program of Federal University of Parana.The approach occurred under a collaborative perspective and directed toward the resolution of problems at local, regional and global levels, promoting a new way of thinking about teaching and learning.Thus, the discipline has been structured opportunity to the literature review and analysis of available materials to supply the demand for more sustainable technologies and materials.Based on different researches, addressed the topic of LCA (life cycle analysis) and AELC (analysis of the energy life cycle) in buildings.Closing the discipline was made through the development of an architectural design, applying the basics covered. The development of architectural design materialized knowledge acquired mainly in environmental impact analysis relating to the materials specified index of CO2 emissions throughout the life cycle of the material, from production to the operational phase of the building.
