One of the biggest problems of the globalizing world is undoubtedly increased energy consumption. Global greenhouse gas (GHG) emission also increases yearly all over the world. For this reason, energy efficiency is a crucial issue in ters of energy savings and environmental impacts. In Turkey, the energy consumption is considerably used for heating and cooling in buildings. It is aimed to minimize the energy consumption for heating and cooling systems by heating insulation applied to different parts of the building such as outer wall, inner wall, roof, floor etc. In this study, for two different insualation materials, optimum insulation thickness of externall wall was determined deal with energy consumption and environmental impacts, especially CO2 emmissions according to the cooling and heating requirements of NKU Rectorate building located in Tekirdağ province. Different scenarios were created by using exterior insulation materials named extruded polystrene (XPS) and expanded polystrene (EPS) with different thickness and simulations were conducted to obtain real data. The aim of the study was to analyze the use of EPS material instead of XPS insulation material by using DesignBuilder and EnergyPlus simulation programs. In the second scenario, a simulation was made by increasing the EPS thickness of 7 cm and the energy amounts were almost equalized. In terms of CO2 emission amounts, the use of EPS resulted in a decrease of 7.2 kg in the first scenario and 25 kg in the second scenario. As a result, it was seen that, XPS usage was 3.5% more efficient in terms of energy efficiency compared to EPS.
