Arquitetura Passiva em João Pessoa: anteprojeto de residência unifamiliar no conceito Passive House___

Abstract

Electricity consumption, driven by economic development and population growth, has significant effects on the global economy. The architecture and building industry increasingly demands electricity, which in turn leads to higher carbon emissions. This paper proposes a preliminary design for a single-family residence in João Pessoa, Paraíba, based on the Passive House concept. Developed in Germany, this construction standard aims to achieve maximum energy efficiency and thermal comfort while minimizing energy consumption. The research begins with a theoretical review of energy efficiency, thermal comfort, and the five fundamental principles of the Passive House standard. It contextualizes the relevance of these principles in hot and humid climates like that of João Pessoa and introduces the energy balance simulation method associated with the Passive House Planning Package (PHPP) tool. The results indicate that implementing passive architecture principles is feasible with appropriate adaptations to the local climate, thereby contributing to the ongoing discourse on energy efficiency in Brazilian residential architecture
