In Europe, residential and service buildings are responsible for more than 40% of primary energy consumption and this ratio is expected to rise. European authorities have undertaken the challange to control domestic energy consumption of buildings to reduce greenhouse gas emissions and the studies on efficient energy use have been accelerated since 1992. Most important outcome of these studies is the European Union Directive on the Energy Performance of Buildings. The Directive underlines the structure of methods which determine the energy performance of buildings for member states. Turkey is revising its legislations on building energy performance as foreseen in Directive on the Energy Performance of buildings through the European Union accession process. “Directive on Energy Performance of Buildings” were introduced in July 2008, urges to develop national building energy simulation methodologies on evaluation of building energy performance. KEP-SDM is one of the simplified methodologies developed based on the regulation.

The methodologies are reliable as long as they are validated. The aim of this study is to assess the accuracy of “KEP-SDM” by “BESTEST”. Climatic zone approach and software-based weather data were implemented into KEP-SDM and the results were compared with eachother. It was concluded that sensitivity of the weather data affects the accuracy of building energy simulation methodologies quite significantly.
