Desempenho termoenergético de edificações no IFPE Campus Recife

Abstract

This research constitutes an investigation into sustainable buildings, with particular emphasis on the principles of energy efficiency, a topic aligned with SDG 11 - “Sustainable Cities and Communities” and with the context of climate change. In this regard, the main objective was to determine the level of thermo-energy performance of the buildings at “IFPE Campus Recife”, focusing on the “Centro de Pesquisa” and “Bloco F”, respectively the newest and the oldest constructions within the institution. The methodological approach combined the techniques of computational simulation, using the softwares EnergyPlusTM and SketchUp, with the Euclid extension, for the modeling and parameterization of each building; and infrared thermography, based on imaging performed with the Flir B335 camera. The buildings were compared under different aspects: albedo/reflectance levels of the envelope, calculated at 65.54% for “Centro de Pesquisa” and 36.23% for “Bloco F”; thermal distribution on the facades, in which “Centro de Pesquisa” presented slightly lower temperatures overall; and energy consumption for air conditioning, with an average annual rate of 88.95 KWh/m2 for “Centro de Pesquisa” and 93.25 KWh/m2 for “Bloco F”. It was possible to conclude that the thermo-energy performance of a building is the outcome of a combination of factors, beginning with its architectural conception during the preliminary studies and design development phases, including specific elements such as the orientation of the facades and the appropriate selection of construction materials, and extending to the color of surfaces, particularly in the building envelope. “Centro de Pesquisa” achieved superior results compared to “Bloco F”, basically in all the aspects analyzed
