Abstract

The construction sector accounts for a large portion of the world's energy consumption; in Iran, it’s more than 40% of energy consumption. Office buildings have a relatively unfavorable energy consumption pattern due to impersonal ownership and lack of supervision and needs improvement. The aim of this research is to achieve the most optimal skin porosity geometry in terms of energy for a dynamic double-skin façade. Since this idea is intended to be used in Mashhad, which is one of the religious centers of Iran, so to create this feeling in users, the geometry used for its dynamic second skin porosity is inspired by Islamic patterns of tiles and decorations of the holy shrine of Imam Reza (AS). By analyzing the energy performance of 5 selected geometries with Ladybug and Honeybee plugins, the most optimal one will be determined. Daylight is one of the most influential parameters in the design of energy-efficient buildings. To make the most of this parameter, it is necessary to create facades with maximum transparency. But these facades face challenges such as overheating. Therefore, it’s important to control the amount of daylight entering. In this research, an optimal geometry for a dynamic double skin façade porosity intended to be used for office buildings in Mashhad is presented, although the energy analysis results of all 5 geometries are very close to each other. This means that the porosity geometry does not have much effect on the optimization of energy consumption.
