Investigating the Influence of Iwan Features on the cooling performance of summer room in Residential structure of Yazd Housing.

In this research, the effect of the effective parameters in the iwan on the cooling performance of summer rooms in the residential structures of Yazd city was evaluated. The aim of the current research is to provide an optimal model for increasing sustainable development for contemporary housing in a hot and dry climate. Therefore, in the beginning, in order to investigate the effect of the effective parameters on the iwan, field studies and typology of the house plans of Yazd were studied, and in the next step, the base models were simulated in the Ecotect software and for data analysis, the EnergyPlus software was used. Then, the criteria and sub-criteria of the optimal iwan model were ranked after determining the weight of parameters affecting iwan and prioritizing them using the analytical hierarchy process (AHP) in Super Decisions. The results showed that the main criteria were ranked in the following order: changing the height of iwan, the effect of the main zone, determining the optimal weight of length, height, and depth parameters on iwan, and determining the optimal dimensions of iwan in (summer rooms). The positive effect of the iwan itself shows the advantage of using this idea in sustainable housing designs and suitable for hot and dry climate
