Energy Renovation of an Old University Building
Main Article Content
Abstract
Old buildings consume a lot of energy and no longer comply with thermalregulations, which creates interior discomfort. Our work consists ofhighlighting the effect of the rehabilitation of the building on energy savings and thermal comfort. The case study is an old building converted into offices.We made a dynamic thermal simulation under TRNSYS 17 to analyze thethermal and energetic behavior of the building. The results obtained afterinsulating the opaque walls and replacing the openings are very conclusive.Surface losses decreased by 72%, the heating power decreased by 67%, andthe air conditioning power decreased by 50%.
