A Critical Analysis of the Energy Requirements of a Commercial Building Based on Various Types of Glass Insulations

Heat loss through the building envelope comprises air leaks cracks and largely windows, which is weakest link of thermal envelope. Therefore, it necessary to devise a systematic approach analyze rightful selection glass for buildings. The investigation energy-saving potential different glasses their comparisons initial capital cost find payback time in terms energy saving by using two types equipment. quantitative simulation study was completed on Hourly Analysis Program (HAP) annual consumption HVAC system seven chilled water results show that performance with tint had better efficiency saving, 3–7 months. A comparison all illustrated float contributes most total cooling load among glasses, were 5.04%, 5.7%, 7.6%, 8.9% N, S, E, W orientations, respectively. Moreover, lowest contribution given tinted double-glazed glass, 2%, 2.3%, 3.0%, 3.01%
