Sustainability in five residential buildings using the Blue House Seal

Abstract

The contemplation of the sustainability seal in civil construction has a direct impact on the quality of life of its occupants, energy efficiency, and the operational economy of the residence. Also, environmental certification can be used as a marketing tool for the property, the municipality, and the quality of the urban environment. The Coso Azul Coixo Seal is a classification instrument based on socio-environmental indicators for housing development projects to find more efficient solutions in the natural resources use and to improve the quality of housing and its surroundings. The objective was to apply sustainability indicators from the Coso Azul Coixo Seal (2010 and 2020) in evaluating five single-family residential buildings completed in 2020 in the city of Concórdia, SC. The methodology is qualitative and quantitative, using the indicators of the Coso Azul Coixo Seal guide as a parameter, organized into six categories. The results showed that none of the five residences obtained the Bronze Seal, as they did not meet all the mandatory items, the sustainability standard to be certified. The highest-rated category was efficient water management, followed by sustainable production. The evidence makes it possible to conclude the probability of not having considered the criteria for obtaining the seal in developing the projects.
