A percepção de corretores de imóveis, construtores e leigos sobre os empreendimentos habitacionais certificados ambientalmente

Abstract

Brazilian cities grew without proper planning when the country ceased to be rural to become mostly urban. From 45% of urban population in 1950, it reached 80% in 2010 according to IBGE (Instituto Brasileiro de Geografia e Estatística). Cities need to grow but should be planned to do so, so that people can live with dignity, health and welfare. The aim of environmental certification of buildings is to make them self-sufficient, with water and energy being captured at the site of the building, treating grey water, taking advantage of rainwater, solar energy and also of favorable winds in natural ventilation, with minimal energy consumption, both in lighting and in heating and cooling the air. The objective of this research is to investigate whether or not housing projects environmentally certified have facilitated commercialization in the city of Curitiba. The perception of builders, brokers and the people that want to buy buildings. The research is qualitative. It describes the methods of LEED certifications, AQUA and PROCEL, and carries out a questionnaire with ten real state, ten building companies and thirty random people of the city. State agents do not give their brokers training on certifications, who believe that real state would be more expensive if they had sustainable technologies. The builders and developers that already construct with environmental certifications do it for high-standard projects and most commercial buildings, where commercialization is facilitated because the increase in the cost of the work is more acceptable in higher-value real state. From the 30 people interviewed, 60% had already heard of environmental certifications. They knew that adopting these technologies can reduce maintenance and operation costs of buildings.
