In modern buildings, it is evident that exterior glazing is highly desirable to enhance the visual environment and provide daylight. This study investigates the energy performance of polycarbonate glazing as a potential substitute for conventional glass. A detailed energy analysis is conducted using a design-builder simulation tool to simulate the performance of multiwall polycarbonate sheet and normal glass for a model residential building. The result shows that the polycarbonate sheet outperforms normal glass. The wall systems’ total annual cooling energy consumption for 16 mm triple 5-wall x-structure polycarbonate and the 3 mm regular single clear glass was 25,834 kWh and 39,565.18 kWh, respectively, resulting in 35% energy savings. Similarly, the skylights’ cooling energy consumption for the same polycarbonate types was 35,776.47 kWh and 63,340.74 kWh, respectively, resulting in 44% energy savings. The impact of aluminum and uPVC framings was insignificant. Therefore, polycarbonate sheets are an excellent alternative to glass.
