Abstract

Reasonable shading can effectively improve the indoor lighting environment and reduce lighting energy consumption. This study aims to study the impact of horizontal and vertical shading devices on the lighting environment of building spaces with different functions. Through computer parameterization and simulation, the indoor lighting environment of offices, classrooms, and residential spaces equipped with two different shading devices are analyzed. Further,energy performance assessments of each room with shading were perfomed. The results show that the daylight performance of horizontal shading devices with a depth of 1.2m is better than that of vertical shading devices in offices, classrooms and living spaces, and the improved UDI is between 15.75% and 17.43%. Due to different lighting standards, shading is useful for residential spaces. The overall effect of adjusting daylight intensity is more uniform than that of the office and classroom. In addition, both forms of shading hadvery weak effects on reducing energy consumption.
