The building energy consumption and heat loss/gain caused by building envelopes are closely related to each other. Accordingly, thermal performance for building envelope needs to be assessed in a precise and objective manner. As a quantitative indicator for thermal performance of transparent building envelopes, the Solar Heat Gain Coefficient (SHGC) or g-value is widely accepted. The SHGC is generally derived by spectrometric method and calorimetric method. From the authors’ previous research, the latter was found to be more appropriate for assessing complex fenestrations. With this in mind, the authors had conducted a series of calorimetric experiment using Artificial Solar Laboratory installed in Korea Institute of Construction Technology. Then the SHGCs of tested fenestration cases were calculated with the results from measurement and simulation. In this paper, the outcomes of measurement and simulation are compared. Additionally, factors that may cause differences between measurement and simulation are discussed. Furthermore, the means to diminish the difference and processes to enhance the reliability of the results are suggested. |
