Due to increasing importance of the concepts of energy efficiency and sustainability, retrofits for a large portion of existing buildings have become an immediate necessity. In this respect, different retrofit strategies are employed for increasing the efficiency of existing building envelopes, energy sources, electrical and mechanical systems. Among the existing building types for efficiency retrofit are the school buildings, which differ from the rest due to their special function - education. The activities taking place in the schools require well established environmental conditions for effectiveness. In Turkey, a large number of high school and elementary school buildings (a total of about 66000 units) have been constructed by repeating a prototype design project to decrease costs and increase speed. Due to the variance of climatic conditions across the country, these buildings have varying environmental performance. Therefore, retrofit of existing school buildings in Turkey has become a necessity and the retrofit strategies that will be produced for these buildings are very important for future generations. The aim of this study is to evaluate the effect of different energy retrofit measures on the sustainability of the schools in different climatic zones. In other words, it is aimed to emphasize that the energy retrofits to be implemented to prototype school projects does not have the same economic, environmental, and social sustainability impacts across different climatic regions. In this study, for the evaluation of four prototype school building in different climate regions and four different retrofit measures, 16 cases were generated. The impact of each case on environmental, economic and social sustainability was evaluated and the sustainability impacts of 16 different cases were calculated as the sum of these three values. As a result of all calculations, a three-dimensional matrix was created to demonstrate the impact of different retrofit types on sustainability in different climatic regions.
