Results and Discussion
To discuss this issue, first the space should be specified as a whole, in terms of volume dimensions and design details. Subsequently, based on the Ilam municipality database, the majority of residential houses were divided into five groups which are presented in Tables 1 and 2 entailing exact or close specifications. Accordingly, the examined samples encompass eight types of residential houses with prevalent volumes and details in the city; they were all the same in terms of total area and air volume, yet different in edge ratios. It should be noted that all eight samples examined were in the same geographical direction.
Initially, it was attempted to examine the thermal and lighting performance of the building in one space regarding the different dimensions presented in Figure 1. The quantitative features of the total area of window opening related to each sample listed in Tables 1 and 2 were analyzed with respect to indices including the amount of consumption at the peak hot and cold periods, the number of comfort days and air conditioning.
