摘要
Double low-E glasses are effective and well-established choices for residential buildings in temperate climatic regions of Sydney,Australia,and Tehran,Iran.The current study’s measurements and field experiments have shown that using a double low-E windowpane can improve window total transmitted radiation energy(TSRE)and daylight glare factor.Nevertheless,spatial daylight autonomy(sDA)and daylight illuminance are the short-comings of using double-low-E glasses.These implications demonstrated that using double low-E glazing is a double-edged sword.Despite its efficiency in improving energy consumption,it cannot satisfy daylight comfort requirements.Therefore,this research intends to find the most suitable solution to exploit double-low-E glasses’benefits and avoid their drawbacks.Subsequently,the genetic algorithm has been used to find the optimum win-dow size through a multi-objective simulation by Climate Studio.The findings suggest that the optimum WWR of 10.35%-10.99%in Tehran brings the daylight comfort metrics above the threshold while the energy consump-tion metrics are kept at a minimum.Similarly,for Sydney,these measures are 20%-24%room length for the horizontal dimension of a window and 33%-40%room height for the vertical penetration dimension.In this way,using a double low-E window pane is justifiable for both examined regions.
