BALANÇO ENERGÉTICO NULO EM HABITAÇÃO DE INTERESSE SOCIAL: ESTUDO DE CASO NO SUL DO BRASIL

Abstract

In Brazil, the energy crisis that occurred in 2001 paved the way for the National Policy for Conservation and Rational Use of Energy. Currently, the production of electricity in buildings as a way to meet their own demand is already a reality. In this context, this article aims to investigate the energy consumption of a housing of social interest consolidated in the climatic context of southern Brazil (ZB2) as well as to evaluate the feasibility of producing photovoltaic electricity to supply the building's energy demand, contributing to the dissemination of buildings with zero energy balance (NZEB). The object of the research is a consolidated building in the Canaã housing complex, from the Minha Casa, Minha Vida program in the city of Passo Fundo / RS. As a method, energy consumption was estimated using the computational simulation method recommended by RTQ-R, the potential for local renewable energy generation through photovoltaic generation, and economic analysis using the tools VPL, TIR and Payback. The work shows that it is possible to implement NZEBs housing from an economic point of view to generate energy in a typology of social interest in southern Brazil.
