Improvement of energy efficiency of buildings in urban areas

Abstract

Although there are a large number of buildings with high energy consumption in Serbia, there is a possibility to reduce it by investing in renovation of such buildings. Windows and doors, which are part of thermal envelope of building, play a very important role in the overall energy efficiency of the building. In this paper, some aspects of reducing energy consumption of buildings in urban area are presented through renovation project and experimental measurements. The results of increased energy efficiency of one public building, obtained by changing doors and windows only, are given. Experimental measurements by thermovision camera in several residential buildings are shown in this paper. These measurements indicate importance of installing adequate windows as part of thermal envelope of buildings. In addition, corresponding data, from overall state of energy efficiency of buildings in Serbia, is presented.
