Window Size in Relation to Thermal Environment |
Abstract |
Windows are important parts of the building envelope and have to fulfill several functions. Besides the primary function-to let in the daylight and allow visual contact and ventilation-they protect against heat and cold.Windows are composed of high thermal-conductive materials and almost openable. Therfor the heat gain and loss through windows is great and we shall consider energy conservation and thermal environment in design of windows.This paper deals with the proper size of window in relation to energy conservation and indoor thermal environment.In Seoul and Busan, the heat flow through window is analyzed. In conclusion, south facing windows perform as net heat gain element if the heat loss of infiltration can be neglected and thermal performance is good.For comfortable thermal environment with relation to MRT, there is proper ratio of window to wall area and the values are presented. |
