عنوان مقاله [English]
One of the building elements having an essential impact on energy conservation is the external envelope of various facades. The building’s external envelope consists of three parts: transparent, semi-transparent, and opaque. The main objective of this study is to design a parametric model to determine the optimal dimensions of the window to reduce energy consumption and maximize the use of daylighting in residential buildings of cold climate (Ilam). In this regard, first, the basic simulation model concerning the typology of residential buildings in Ilam was determined , and using weather statistics of Ilam’s weather station, the weather file for simulation was validated. Then the modeling and simulation based on energy consumption parameters were performed and the optimization process was carried out using Rhino software, Honeybee & Ladybug plugins, and finally, the optimal window dimensions for various cases and south and north facades were introduced. The results show that the optimal window to wall ratio on the south façade without any shading devices is 24 % and with Code No. 19 suggested shadings it is 19%, while the value for the north façade is 4%.
