Solar energy, which is inexhaustible and clean, has been widely used in passive or positive manners. A well-constructed passive solar house can improve the indoor environment and save energy of mechanical systems. Design of glazing system plays a vital role in passive solar buildings. This paper analyses influence of glazing systems on indoor environments of a passive teaching building in Lhasa, southwest on the Tibetan Plateau, China, for the purpose of optimizing retrofitting its windows. In this project no HVAC system is used, so indoor temperature is the main factor for evaluating the performance of different glazing systems. Four glazing systems were compared by computing uncomfortable hours and net heat addition of windows, using DesignBuilder. Economy is compared as well. Results show that single lowe clear 3mm (e=0.2) glazing leads to the most comfortable indoor environment in this project. Net heat of windows and comfortable rate are suggested to assess the overall performance of glazing systems. Generally speaking, we can’t use SHGC or U-Value to determine the best glass system only in the actual situation. Careful simulation is necessary to obtain the comprehensive performance of windows in a passive solar building.
