Determination of the Effect of Different Window Parameters Windows on Energy Consumption in Buildings by Design of Experiment

ABSTRACT The increasing dependence on energy around the world necessitates the effective use of energy in every field for a sustainable world. Especially in the last 20 years, solutions for the energy efficiency have been developed in many sectors. In the field of architecture, laws and regulations have been developed, as the building sector has a great potential for energy consumption in both manufacturing and use phases. This study was conducted by analyzing the case study in TS 825 within the framework of TS 825 rules that must be followed in line with the "Regulation on Energy Performance in Buildings" published in Turkey. According to regulation, building elements should be within certain limit thermal conductivity values according to the climate zones. Case study’s wall, floor and roof elements were modeled according to U-values required in the 1st degree climate zone. In order to investigate the effect of different parameters of windows on total energy consumption, scenario combinations were created using the statistical design of experiments method. Finally, it was found that the ratio of windows to facades and thermal conductivity values affect the total energy consumption at the highest rate in a building in Izmir.
