Assessment of the impact of windows and building orientation on the energy intensity of container houses using BIM

Abstract

With the rapid development of the container industry, the use of container houses has become extensive. This paper uses the method of orthogonal experiment to study the change of the energy consumption of the container by changing the size, height, direction of the container window and the direction of the container building. The building used a container house in Xiangfang District, Harbin City, Heilongjiang Province, China as a case. 71 scenes were created, 3D modeling was performed using Revit and imported into Green Building Studio for Energy Use Intensity (EUI) calculation. This research is divided into three processes. The first process is to study the impact of window-to-wall ratio. Through the first process, a rule is obtained, and the height of the window has the greatest impact on energy consumption when the window-to-wall ratio is 0.2. Therefore, in the second process, the window-to-wall ratio of the windows is fixed to 0.2. When the height of the windows of different orientations changes, the energy consumption of the container house changes. In the third process, based on the results of the first two research processes. the orientation of the container house is changed, namely the north-south orientation and the east-west orientation, and the energy use intensity calculation is performed again. The results show that the window-to-wall ratio has the greatest impact on the energy use intensity of the container house. The larger the window-to-wall ratio, the greater the energy consumption. The height and orientation of the windows have an impact on the energy use intensity but not much.
