| Summary: | Orientation and the building facade glazing percentage are two parameters necessary to be considered during the early stages of architectural design in order to determine the location of the building on site and control the balance between the transparent and opaque parts of its envelope. The aim of this research is to specify the optimum values of orientation and glazing percentage of building facade and finding the effect of deviating the variables from the optimum values on the total building energy consumption. The cases of this research are the schools constructed based on the current standards and specifications of Iran’s Organization for Renovating and Developing Schools in humid temperate climate. Due to interrelation between these two parameters, their impacts are studied concurrently. Research questions are: 1-What is the optimum orientation angle and facade glazing percentage of school buildings in designated climate, in terms of the lowest energy consumption? 2-What is the sensitivity factor of these variables in different situations on total energy consumption of the building? 3-What is the differences of changes due to deviation from the optimum values, for each parameter? In this research the Latin Hyper-cube method is used for sampling the input values; and Designbuilder program with Energy Plus simulation engine is used for modeling and analysis. According to the results of this study south-facing buildings have the optimum orientation with whatever glazing percentage. However, the optimum glazing percentage depends on the building orientation and would differ from 40 to 55 percent. This study shows that increasing the glazing percentage of school buildings up until 40 percent for east–oriented buildings has the most significant sensitive effect on building energy consumption, whereas increasing it more than this value didn’t show a considerable effect. |
