“…Parameters such as interest rate, inflation rate, wall resistance, cost of fuel, insulation material, and thermal conductivity are different from each other in the calculations, so that results show variation when making comparison. Bektas Ekici et al [19] used different wall components thicker than those used in this study. Ozel [18] made the model calculations for both heating season model building created by the data taken from the State Institute of Statistics (Prime Ministry, Republic of Turkey).…”

“…Ozel [18] analyzed a system with a 20-year life and showed that the optimum insulation thickness value varies between 5.4 and 19.2 cm, the energy savings vary between 86.26 and 146.05 US$/m 2 , and the payback period varies between 3.56 and 8.85 years. Bektas Ekici et al [19] calculated the optimum insulation thickness, energy loss, and payback periods for four cities selected from different climatic regions according to the TS 825 (Antalya in the 1st region, Istanbul in the 2nd region, Elazıg in the 3rd region, and Kayseri in the 4th region). The optimum insulation thickness varied between 0.2 cm and 18.6 cm, energy savings varied between 0.038 US$/m 2 and 250.415 US$/m 2 , and the payback period varied between 0.714 and 9.104 years.…”

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$/m 2 and 43.95 US$/m 2 , 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 CO 2 emissions for the country are calculated to be 57.2 billion kg CO 2 per year after insulation.

Bektas et al [2] investigated the effects of the wall type and degree-day values on the optimum insulation thicknesses for different insulation materials. The calculation was carried out for four different cities in different climate zones in Turkey.…”

“…[32] β is the angle between horizontal plane and inclined surface, which is 90 o for a vertical wall. cosθ = sinδ.sin(φ-β) + cosδ.cos(φ-β).cosω (12) cosθ z = sinδ.sin φ +cosδ.cosφ.cosω (13) The hourly reflected radiation (I r,t ) is given in Equation 14. It is assumed that the reflection is considered as isotropic and the reflectance of beam and diffuse radiation are identical.…”

Betül BEKTAŞ EKİCİTS 825 Thermal Insulation Requirements in Buildings, the obligatory standard, is still in effect, and is used to calculate the heating energy requirements of buildings in Turkey. The total solar heat gain through windows is calculated using the solar radiation table given in Appendix-C of TS 825. Although Turkey is divided into four different degree day regions according to this standard, Appendix-C offers the same solar radiation data for all regions. This study aimed to investigate the appropriateness of the Appendix-C table for the different degree day regions. The hourly solar radiation on the vertical surfaces of a building envelope was calculated for 16 selected cities. Long-term sunshine duration data for each location were obtained from the Turkish State Meteorological Service. It is demonstrated that the solar radiation table given in Appendix-C of TS 825 is not appropriate for the four degree day regions. The calculated solar radiation values of the cities are considerably different from the table values, with the ratios varying between 3.03% and 69.15% for horizontal surfaces, 0.171% and 53.29% for south, 0.25% and 22.15% for north and 0.60% and 40.42% for east and west oriented surfaces.
