Determination of Optimum Insulation Thickness for Different Climatic Zones of Turkey

Abstract

Turkey has dynamic economic development and rapid population growth. It also has macro-economic and especially, monetary instability. The net effect of these factors is that Turkey’s energy demand has grown rapidly almost every year and is expected to continue growing. Since 1990, energy consumption has increased at an annual average rate of 4.3%. The energy consumption is distributed among four main sectors which are industrial, building (residential), transportation and agriculture. Approximately 33% of total energy consumption in Turkey is used by residential sector. This situation makes it more important to insulate buildings in our country where fuel prices are too high. Turkey is divided into four climatic zones depending on average temperature degree days of heating. In this study, the four different cities of Turkey, Izmir, Istanbul, Ankara and Erzurum are selected to determine the optimum insulation thickness of the external wall of buildings. Optimum insulation thickness for six different energy sources (Soma coal, natural gas, coal, LPG, fuel-oil, diesel fuel) and two different insulants (extruded polystyrene, rock wool) is calculated and compared to each other. In addition, by using life cycle cost analysis method. Pay back period is calculated for each zone.

Calculate optimum insulation thickness to all over Indian city and compare it with the degree day method

“…The optimum insulation thickness varies between 5.3-12.4 cm depending on the type of fuel used. Kurekci et al (2009) and Nuri (2016) divided Turkey's climate zone into four parts depending on the average temperature DD and applied insulation material and evaluated that about 33% of energy is consumed in the residential sector. The calculation of optimum thickness value is based on using six different energy fuel, i.e., soma coal, natural gas, coal, LPG, fuel oil, diesel and, two insulation material (extruded polystyrene, rock wool).…”

Determination of Optimum Insulation Thickness for Different Insulation Applications Considering Condensation

“…Questions arise at this point regarding the extent of increment in insulation thickness and variation of such an increment according to environmental conditions. There are a number of studies in the literature on the optimization of the insulation thickness to be applied on the outer walls [1][2][3][4][5][6][7][8]. The degree-day method was used in those studies for the heat loss calculations.…”
