Resumo
The building sector is responsible for 51% of the electricity consumed in Brazil, and about 10% of the total greenhouse gas emissions. These numbers continue to grow, despite significant efforts made by the government to promote the adoption of building energy efficiency (BEE) technologies, which have not been widely adopted due to barriers. A systematic literature review revealed 27 barriers, classified into six categories, as being responsible for hindering the adoption of energy-efficient technologies. This article aims to verify whether such barriers make sense in the Brazilian context. In order to accomplish this goal, a survey among one thousand Brazilian professionals was carried out. The results are analysed by two multivariate techniques, cluster and factor analysis, validating these barriers as well as the proposed taxonomy for Brazil. The results also show that the two most important categories of barriers are Governmental/Political/Regulatory and Financial/Economic, showing that Brazilian society has high expectations that the government will be more active in this matter. In addition, the survey respondents gave insights into important points concerning technology, education, etc. that should be verified in a timely manner. These findings can assist government agencies, researchers, and experts to develop guidelines/strategies to overcome such barriers.
