Abstract

Validation model was generated by WINDOW 7.6 software to simulate the temperature changes of laminated glass. This approach is used as a validation model to compare the real time temperature changes observed. The parameter in the test were clear laminated glass and coloured laminated glass with using singleand double-glazed technology to assess the impact of optic glass, including U-Value, SHGC, and additional layer application of laminated Glass (Double Glazing Technology) in building temperature changes for creating thermal comfort. The results showed that single glazed technology application on clear laminated glass adjust the room temperature between 30.2°C to 31.4°C. In comparison, single colour laminated glass technology application set the room temperature 27.7°C to 28.5°C. Interestingly, the double-glazed application reduced the indoor temperature between 27.1°C to 28.5°C. These results showed that buildings’ significant thermal performance could be accomplished by applying doubleglazed technology. Nevertheless, double glazed technology was not suggested to apply in all of the skin of tropical building design due to the high-cost issues.
