Abstract:

Approximately 70% to 80% of the energy consumption used in buildings is for heating, cooling and producing hot water. One of the main measures that can be taken for energy savings in buildings is heat isolation. In this study, a comparative study was presented taking into account different insulation materials and CO2 emissions in the determination of the most economical combination of optimum insulation thicknesses in different types of fuels for energy savings in the winter and cooling of buildings in the summer. For this purpose, the degree-hour method and life cost analysis were used. The calculations are made for four different insulation materials and two different fuels. The optimal isolation thickness that makes the cost at the minimum of the study is 0.012-0 for heating in the winter months for the Sea Sea. 031 m for cooling in summer and 0.009-0.022 m for cooling in summer. CO2 emissions decrease logarithmicly with increased isolation thickness. Polyurethane is more suitable for specific conditions, with a difference of 22-24% in energy savings as a isolation material, with a difference of 10%-34% in CO2 emissions. In terms of energy savings, coal is about 9-11% more economical than natural gas. In terms of environmental impact, natural gas can be preferred with a reduction of CO2 emissions of 37-40% according to heating with coal. The lowest values for CO2 emissions in the Denizli province are obtained in the building, covered with polyurethane insulation material, used as a source of heating natural gas.
