Abstract
Based on an experimental study, this paper discusses the savings obtained by various kinds of single-layer and double-layer glass panels on the cooling power consumption in the air-conditioning of buildings. Heat transfer coefficients are measured in order to evaluate the savings obtained. Results show that double-layer glass panels offer significantly larger savings compared to single-layer glass panels, and the flow of the air layer within the double-layer glass panels is not significantly helpful to improve the energy-saving effects. It is also found that the Low-E glass material has the greatest reduction effects.
