Análise de práticas sustentáveis e viabilidade econômica para obtenção de certificação ambiental Selo Casa Azul + Caixa de um empreendimento de habitação de interesse social na cidade de Caruaru, Pernambuco

Abstract

Advances in the field of civil construction have caused several environmental impacts, due to the absence of sustainable development policies. This article presents an evaluation of sustainable practices based on the criteria of the checklist, updated in April 2022, of the Casa Azul + Caixa Seal environmental certification, proposals for improvements and their economic feasibility, applied to the project of the Minha Casa Minha Vida Program, the Parque Caminho das Orquídeas condominium, located in Caruaru, Pernambuco. The costs of the improvements were calculated according to the table of the National System of Prices and Indices for Civil Construction and through local research.  The work reached the Topázio gradation, which was old Prata gradation, due to changes in the Casa Azul + Caixa Seal checklist in 2022. To achieve the Sapphire gradation, previously named Gold, it would be necessary to reach 5 more points at a cost of R$ 20,126.00, less than 1% of the total cost of the work. The Diamond Category could be obtained with 25 points, at a cost of R$ 1,268,369.38, that is, 6% of the total cost of the work. The results show that it is economically feasible to adhere to sustainable solutions in social housing, and it is important to encourage the parties involved in the process (public authorities, financing agencies, construction companies and society).
