Abstract
In today’s world, improving the energy efficiency level constitutes a focal point in Turkey’s energy policies, just as in other countries, in order to achieve a fast and cost effective solution to globalising energy and environmental problems and to create a sustainable, resource efficient economy which encompasses transformation and growth. In this context for Turkey, while the importance of studies on energy efficiency to ensure energy supply security is increasing, housing constructions which lead to a very high level of energy consumption are also growing. Therefore in this study strategies which are effective in improving energy performance of residential buildings with the goal of achieving optimum benefit for country resources and decision makers are developed for the different climate regions and the energy, economic and environmental performance of residential buildings related to these strategies are evaluated by means of the comparative approach. Thus, it is possible to obtain data from design and retrofit of buildings, which may provide a basis for relevant laws and regulations on optimising energy, economic and environmental performance of buildings and support for preparing technical information required to improve energy and cost efficiency levels of both existing and new residential buildings.
