Two types of glass curtain buildings were constructed on the roof of the NTUST E2 building. Both buildings had glass installed on the east, south, west, north and top sides. One building used tempered glass; the other used Heat Insulation Solar Glass (HISG). We calculated each glass' solar heat gain coefficient (SHGC), shading coefficient (SC) and thermal transmittance (U-value) by measuring the transmittance and the reflectance. We also used simulation analysis to check the results of thermal comfort, energy consumption and power generation. Tests were done both with and without air conditioning. The results showed that without air conditioning, the HISG curtain wall building provided much greater thermal comfort than the tempered glass curtain building. Tested with air conditioning, because of HISG's great heat insulation and heat preservation ability, the HISG curtain wall building saved 46.8% of energy when the cooling system was in use, and saved 44.2% of energy when the heating system was in use. Since the HISG curtain wall building could generate electricity, the results also showed that the power generated could not only supply the energy needed for both cooling and heating but also have a surplus of 368.6kWh in a year. Furthermore, the simulation analysis indicated that a HISG curtain wall building may have the potential to save up to 80% of the energy used for the cooling system, higher than what was exhibited by our model HISG curtain wall building.
