Optimum insulation thickness payback times, energy saving analysis for İzmir based on two different wall types and three fuel types Analysis the amount of carbon dioxide and sulfur dioxide for the heating period outdoor wall unit area Heating period per capita carbon dioxide and sulfur dioxide analysis
Theory and Methods:This study comprises three stages as the first stage 2 different fuels, 3 different insulation materials, 2 different externally insulated wall are investigated for effects on optimum insulation thickness (OIT) in cases of different components of external walls, total cost, energy savings and repayment duration according to the lifetime cost analysis method. In the second stage comparisons are exposed for carbon dioxide and sulfur dioxide amounts released per unit area (m 2 ) in the heating period according to wall, fuel and insulation material type without insulation. The effect of OIT on the environment and energy for İzmir is determined for the first time in the literature. The third stage of the study presents two different approaches of carbon dioxideand sulfur dioxide amounts per capita in the heating period for coal and natural gas emissions.
Purpose:This study is performed for İzmir, which indicates that if coal is used as fuel in insulated and uninsulated buildings then the amount of CO2 and SO2 emissions increases per unit area during the heating period, whereas the amount of CO2 decreases by using natural gas as fuel. On the other hand, the amount of CO2 and SO2 per capita for coal and for natural gas are presented in detail as a new contribution to the existing literature.
Results and Conclusion:In cases of natural gas usage as fuel in a building with an externally insulated exterior wall, the amount of CO2 emission will decrease by 57% for XPS, 58% for EPS and 56% from the unit area during the heating period for Stone wool compared to the uninsulated wall, while the heating period for the sandwich outer wall will reduce CO2 emission from the unit area. It has been demonstrated that the amount of CO2 will decrease by 57% for XPS and EPS, and 56% for Stone wool. The heating period in an uninsulated building is the heating period of 1839 kg per capita for natural gas. If the building is insulated with XPS according to OYK, the amount of CO2 per capita will decrease by 76%in the heating period. If coal is used as fuel then the heating period in an uninsulated building is determined as 3484 kg per capita CO2 per capita, and in case of insulation with XPS according to OYK, 838 kg / capita heating period. In addition, it has been revealed that the amount of SO2 per capita in the heating period for the externally insulated exterior wall for coal will decrease by 73% compared to the uninsulated wall, while this rate will be 69% for the sandwich walls. With these approaches introduced to the literature, the heating period CO2 SO2 amounts in any province of the world can be easily calculated with the parameters in Equations 22 and 23.
