Paper Title
Investigation of Glaze Characteristics on Building Energy Performance in The State of Kuwait

Abstract
Energy consumption evaluation was performed on a public housing building located in Kuwait to highlight the effect of glaze coating on the overall energy efficiency. DesignBuilder simulation software was used to construct and model the building and estimate its electricity consumption when applying different glazing conditions. Solar heat gain coefficient, light transmission, and solar transmission values of the tested glazes were obtained experimentally before and after modifying the glass surface properties. Single layer nanocoating, multi-layer nanocoating, nanoceramic film, and 30% tented film were used on a double-glaze glass for the modification purpose. The initial building designed that had the double-glaze glass showed an annual consumption of about 62.2 MWh, while the added multi-layer nanocoating case demonstrated a consumed of 56.3 MWh. Comparing the two cases, the overall energy saving showed to be roughly 9.5%. The present study confirms that using nanocoating can be beneficial toward reducing building overall energy consumption.
