Abstract:

In this study, energy saving and energy cost saving based on the life cycle analysis were examined considering the last two versions of TS 825, depending on the earth-air heat exchanger used for heating and cooling the buildings. In addition, the amounts of emissions (pollutants) emitted to the atmosphere as a result of the use of electricity as an energy source during electricity generation from power plants were investigated. For the amount of electrical energy used, the heat transfer coefficients of the building envelope covering the external wall, ceilings, floors, and windows, which are recommended in our country's insulation standard TS 825, were used. Energy-saving amounts were determined by using the building envelope heat transfer coefficients in the 2013 version and the 2008 version of TS 825. The degree-day method was used in the energy consumption calculations related to the building envelope elements. The heating degree days and cooling degree days used in the energy consumption calculations of the buildings during the heating and cooling periods were calculated depending on the outdoor dry bulb temperature, the wet bulb temperature found with the relative humidity, the solar radiation value and the solar air temperature found. As pollutants, substances affecting global warming (CO2, N2O, CH4), ozone depleting substance (CFC-11), inorganic pollutant (SO2), air polluting particulate matter (PM) were examined. By using the 2013 version of TS 825 instead of 2008, savings of up to 4.9 % are achieved for all degree-day approaches, considering all four climate zones connected to external walls and flooring. There is a savings of up to 6.0 % due to flooring. According to the energy consumption and emission values related to the window, the savings have been determined as 25 % for all climate zones.
