Análise de projetos de habitações de interesse social com ênfase na avaliação econômica e ambiental

Abstract

Given the importance of developing tools that assist designers in decision-making, the purpose of this work is to present an environmental and economic assessment, focused on identifying the most sustainable alternative in single-family housing projects of social interest. This assessment will be carried out in two construction typologies: Housing Project A (PHA) which involves a 49.09 m² house with a single floor, built in reinforced concrete, and Housing Project B (PHB) which deals with a house of 44.78 m² with a single floor, built in structural masonry. After defining the projects, an assessment of the life cycle itself was conducted, with the aim of evaluating the environmental impacts caused by them, and an economic assessment to define a cost estimate. The evaluation results indicate that, in the environmental dimension, the PHA demonstrates more significant environmental impacts. Regarding the economic dimension, the PHB is economically more attractive. This study contributes to the advancement of sustainability in the construction of social housing projects. The proposed assessment serves as a basis for the inclusion of environmental and economic dimensions in the design and sizing of projects, allowing the generation of scenarios for sustainable decision-making.
