An application for energy performance evalution and usability of the energy performance calculation methodology in buildings (Bep-Tr)

An important part of consumed energy is used by buildings. For this reason, European States published "The Energy Performance of Buildings Directive" in 2002. With the same purpose, Regulation on Energy Performance of Buildings was made and Bep-Tr software was developed in our country in 2008. The purpose of thesis that contains five main subjects, the results that are concluded from the thesis and studies on this field are explained in introduction part with literature research. In the second chapter, two studies are done to support the thesis study. In the first study, the heating and cooling energy loads of the sample building in five climatic regions according to different insulation thicknesses are analyzed with The Energy Performance Calculation Methodology in Buildings (Bep-Tr). In the second study, personal interviews are done with engineers and architects who specialized in Energy Identification Certificate and working for Trabzon province on the subjects of the usability of Bep-Tr program and application of Energy Identification Certificate. Statistical evaluations of the data that are obtained from the studies are done in the third chapter. In the fourth chapter, the results of the studies are specified. In the fifth chapter, suggestions about the usability of Bep-Tr program and application of Energy Identification Certificate are offered with regard to the data based on analysis study that is done with Bep-Tr program and interviews with the people specialized on Energy Identification Certificate. Key Words: Energy Efficiency, The Energy Performance Calculation Methodology in Buildings(Bep-Tr), Usability of Bep-Tr, Energy Identification Certificate
