Abstract
In this study, the optimum insulation thickness of the external walls of the housing and it’s energy saving and environmental impact in the provinces—Ardahan, Aydin, Eskisehir and Samsun—located in four different climate regions of Turkey was calculated for the expanded polystyrene and polyurethane insulation materials. Natural gas and coal were selected as fuels. Ardahan in the coldest climate region and Aydin in the hottest climate region, for the coal and optimum thickness of expanded polystyrene and polyurethane insulation materials, the reduction of CO2 and SO2 emissions. In the study, the relations between annual energy cost saving and insulation thickness are given. The value of energy cost saving increases up to optimum insulation thickness and beyond this level, the energy cost saving is decreased. For coal and optimum thickness of expanded polystyrene and polyurethane insulation materials, the energy cost savings was higher for the cold climate regions when it was compared with the hot climate regions.
Highlights
Energy, because of the world’s population and standard of living with constant increase, has become an important resource and power

Summary
Because of the world’s population and standard of living with constant increase, has become an important resource and power. Due to the limited amount of fossil fuels, increase of the energy price, environmental problems and global warming, it is important to use energy efficiently [2] [3] [4]. Turkey can be considered a natural bridge between West and East or Europe and Asia [5] According to the data of Ministry of Energy and Natural Resources (MENR), total energy consumption in Turkey in 2013 was 120.3 Million Tons of Oil Equivalent (MTOE). Primary energy demand in Turkey is met by natural gas (31.3%), oil (28.2%), hard coal (14.7%) and lignite (11%). Turkey imports nearly 98% of the natural gas and 93% of the oil it consumes and coal import of Turkey increases steadily [6]
