Sustentabilidade na construção civil: proposta de diretrizes baseadas nos selos de certificação ambiental

Abstract

Sustainable development, despite being recurring theme in academic, scientific and political meetings, walks slowly in regard to the conditions of the planet Earth. Whereas the construction industry is responsible for a significant amount of pollutant emissions in the atmosphere and general damage to the environment, this dissertation concentrates on elements of sustainable construction, focusing on the requirements of environmental certifications in Brazil. The main objective of this work is to define guidelines for sustainable projects, based on the environmental assessment categories and criteria of the most used seals in Brazil: LEED, AQUA and Selo Casa Azul, considering the contribution to the four life support systems on Earth, which are: Atmosphere, Water, Soil and Living Beings. In addition, a brief analysis of market practices allows us to map the landscape of construction as sustainable. The method used is based on a literature review on sustainability and its evaluation systems in the environment built at the first moment. The development of the research is based on the foundations of Design Science Research as a way of generating knowledge. A qualitative analysis of the certifications is made to synthesize them in guidelines. As a result, the guidelines generated are contrasted with market practices, allowing us to quantify the level of sustainability in our built environment. This dissertation contributes to the improvement of the sustainable management of the built environment, as well as to the awareness of the urgent need of sustainability in it.
