Abstract
One of the most important considerations to be considered in the design of energy efficient buildings is the thickness of the insulation to be applied to the building. In this study the existing building stock in Turkey has been investigated depending on parameters such as the height and the area. A model building has been created covering all of these buildings. Fuel emission reduction of combustion system was calculated in the case of insulation applied to this model building. Heat loss of the existing building stock and exhaust emissions and the contribution to the country's economy with the model building methodology are also determined. The results show that the optimum insulation thicknesses vary between 3.21 and 7.12 cm, the energy savings vary between 9.23 US$/m2 and43.95 US$/m2, and the payback periods vary between 1 and 8.8 years depending on the regions. As a result of the study when the optimum insulation thickness is applied in the model building, the total energy savings for the country are calculated to be 41.7 billion US$. And also total CO2 emissions for the country are calculated to be 57.2 billion kg CO2 per year after insulation.
Highlights
Regulations regarding the thermal insulation of buildings utilize the calculation method stated in the TS 825 (Turkish standard) compulsory
The results show that the optimum insulation thicknesses vary between 1.06 and 7.64 cm, energy savings vary between 19 US$/m2 and 47 US$/m2, and payback periods vary between 1.8 and 3.7 years, depending on the city and the type of fuel
Ucar and Balo [14] examined the energy savings and payback periods in the four climatic regions of Turkey for four different insulation materials applied to the external walls in the cases of five different fuel sources
Summary
Regulations regarding the thermal insulation of buildings utilize the calculation method stated in the TS 825 (Turkish standard) compulsory. In a subsequent study in 2009 [13], the optimum insulation thicknesses of the external walls, energy savings, and payback periods over a lifetime of ten years were calculated using the P1P2 method for five different fuels, four different insulation materials, and various cities in Turkey. The results show that the optimum insulation thicknesses vary between 1.06 and 7.64 cm, energy savings vary between 19 US$/m2 and 47 US$/m2, and payback periods vary between 1.8 and 3.7 years, depending on the city and the type of fuel. Ucar and Balo [14] examined the energy savings and payback periods in the four climatic regions of Turkey for four different insulation materials applied to the external walls in the cases of five different fuel sources. Calculations of the optimum insulation thickness were made for natural gas
