Evaluation of The Energy Performance of Shading Devices based on Incremental Costs
Authors: Jian Yao, Chengwen Yan
Abstract:
Solar shading designs are important for reduction of building energy consumption and improvement of indoor thermal environment. This paper carried out a number of building simulations for evaluation of the energy performance of different shading devices based on incremental costs. The results show that movable shading devices lower incremental costs by up to 50% compared with fixed ones for the same building energy efficiency for residential buildings, and wing panel shadings are much more suitable in commercial buildings than baring screen ones and overhangs for commercial buildings.
Keywords: Solar shading, Incremental costs, Building energy consumption.
