Requalificação de edifícios: anteprojeto arquitetônico do centro de convivência Djalma Marinho da UFRN com enfoque na eficiência energética da envoltória

Abstract

This study addresses building requalification focusing on the envelope’s energy efficiency. The work proposes a requalification for Centro de Convivência Djalma Marinho’s building, located in UFRN’s main campus in Natal/RN. From a Post-Occupancy Evaluation of the built environment, an analysis about the existing building’s thermal comfort conditions was performed, and a new architectural brief was proposed. By applying passive bioclimatic strategies, as recommended for Brazilian Bioclimatic Zone 08, the design intention is reducing heat transfer from the external environment to the internal environment, improving thermal comfort for users and reducing energy consumption. The presented actions aim an enhancement of the building envelope’s energy and thermal performances, to obtain the Etiqueta Nacional de Eficiência Energética da Edificação (PROCEL), and offer the academic community a space with better environmental quality. Rationalizing materials and resources resulted in an executable design, which according to WebPrescritivo, obtained a label corresponding to class “A” for building envelope. This architectural design for requalification emphasized thermal properties of materials and the employed building systems.
