Impact of Southern Window-to-Floor Area Ratios on the Thermal Performance of the Settlement in the Hot and Dry Climate (Case Study: Kashan City)

A major party of generated energy is now used for heating and cooling buildings. Hence, it is beneficial to apply solutions that reduce the thermal load of buildings. However, solutions for energy consumption reduction always face barriers. Optimizing window proportions in energy consumption saving is highly influential in this case. The window is one of the main components that receives solar radiation energy but also serves as a thermal bridge transmitting energy from interior to exterior space. This s tudy inves tigates the climate conditions of Kashan. It determines materials as cons tant variables to examine the impact of southern window-to-floor area ratios on the thermal performance of settlements in hot and dry climates to achieve higher efficiency of this element using simulation of different models through EnergyPlus software. This s tudy then examines the cooling and heating load created in interior space considering variable elements of ratios, window elongation, and window-to-floor ratio, using single and double-glazed glass and its analysis considering meteorological data of this city using EnergyPLus software. Finally, the mos t optimum southern window-to-floor ratio was determined. This s tudy aims to achieve efficiency and the highes t impact of the southern side's window of a building on the thermal performance of the building by simulating various models through EnergyPlus software. This s tudy has used the descriptive-analytical method, then analyzed the obtained results, and las tly outlined the priority of application among models as follows:۱.۳۸ ratio, ۱ ratio, and ۱.۹۵ ratio. In contras t, the mos t optimum window ratio is a ۱۵% window-to-floor ratio with ۱.۳۸ proportions and eas tern and wes tern elongation using double-glazed glass.
