Buildings in hot countries experience significant amount of heat gain through windows and this affects the thermal comfort of buildings' occupants. The proposed glazing is specially designed to reduce the electricity consumption for lighting and cooling. The optical properties of the glazing have been optimized by using rigorous coupled-wave analysis method. The glazing consists of ITO and four periodic pairs of Si/SiO2, deposited on a glass sheet. The fabrication of the glazing and the testing has been performed at the laboratories of the Faculty of Science, University of Witwatersrand, South Africa. Magnetron sputtering technique has been used for the fabrication. The optimum thicknesses of ITO, Si and SiO2, obtained from the simulation and the experimental work, are 0.1 μm, 0.15 and o.4 μm, respectively. The glazing transmits 70-80% of the visible light and reflects almost all the infrared radiation.
