Abstract |
This study conducted experimental research on glass, a vulnerable component in building envelope systems, to evaluate its thermal performance. In this study, thermal and energy performance were measured using an on-site chamber. The evaluation is subject to the various types of low-e multi-layer glazing and double glazing with internal blind. Each glass specification testified under cooling and heating period to derive the performance indicators which include solar radiation transmittance, glass surface temperature, solar and energy reduction. The experiment of the low- e multi-layer glass combination showed that triple low-e double glazing is more effective in energy saving than single low-e double glazing during cooling and heating period. Triple low-e glazing consumes less energy for 33.7% during cooling period and 17.4% during heating period. Similarly, the experiments conducted on the internal blind group. The implementation of internal blind demonstrate superior performance than low-e double glazing system. Internal blind consumes less energy for 48.8% during cooling period and 16.1% during heating period. |
