Heating Energy Performance of Heated Glass According to Insulation Level of the Residential Building
Journal of the Korean Solar Energy Society
Heat losses through exterior windows and condensation on their surface can cause thermal discomfort inside a building. In addition, the use of low energy-efficient windows tends to increase thermal heat losses, and thus building energy consumption. In this study, we present the performance evaluation of heated glass in a residential building when the system is applied to a building and used as a heating system. In this study, a simulation-based analysis was conducted to evaluate the heating
... gy consumption based on the insulation standards with different areas and types of heating systems in a residential building. The results of this study reveal that the heated glass used a relatively higher heating energy consumption when compared to those of the other two heating systems, including floor radiant heating and air-source heat pump systems. Although the heated glass exhibited the highest energy consumption, it is expected that the system can be used as an alternative to other systems, such as a floor radiating heating system. This is mainly because the heated glass includes high benefits of indoor thermal comfort and prevents the window surface from forming condensation. In terms of combinations of heating systems, a case that includes radiant floor and heated glass heating systems can be considered as the best option based on the study analysis because the traditionally preferred heating method in Korea is based on a radiant floor heating system.
