Abstract: (1143 Views)
Form, as the front line of exposure to the external environment, defines how the building contacts climatic elements, including solar radiation. Therefore, the different components of the form also affect the amounts of solar factors received by the building and cause a change in the energy performance of the building. Due to the presence of solar heat gain (SHG) and visual transmission (Tv) components in solar radiation and the simultaneous activity of office uses with the presence of daylight, not paying attention to these two components at the same time can lead to a departure from the conditions of thermal comfort and visual comfort. Therefore, to increase productivity in office applications, it is necessary to investigate the behavior of forms against solar radiation and remove unsuitable types. To achieve the optimal form for the mentioned applications in future cities, this research aims to evaluate the energy performance based on the fourth edition of topic 19th of the National Building Regulations by examining a frequently repeated form. This research was done with the descriptive-analytical research method. The required documentary data were extracted from valid databases and after modeling with DesignBuilder software, the outputs were described and analyzed. As a result, rectangle and square shapes have formed 69% of the form of these buildings with frequency of 38% and 31%, respectively. The proposed type A2 with a length-to-width ratio of 2 to 1 has the most optimal performance against solar heat and visible waves from the perspective of thermal comfort and optical visual comfort.
