| Abstract: | In this paper, a comparative field measurement was done in two test rooms. After that, the influence of exterior shading device on indoor thermal performance is evaluated from different aspects namely operative temperature, radiant temperature asymmetry and PMV-PPD. Using Gennusa＇s model of mean radiant temperature, radiant temperature asymmetry drops from 25℃ to 5℃ and PMV drops from 2 to -0.2 after blind was on, which proves that exterior shading device has a significant effect on indoor thermal environment. |
