Energy saving is one of the opportunities in residential and commercial building sectors. Proper selection of window glasses reduces the energy consumption in the built environment. The objective of this work is to ascertain the best glazing and it's orientation to save the high air-conditioning costs in buildings of the Dhaka in Bangladesh. This article presents the experimental results of solar optical characteristics of four different glasses such as clear, tinted bronze, tinted green, and bronze reflective glasses. Burnt brick buildings were modeled with four different glasses and analyzed for air-conditioning cost-saving prospects. The results reveal that among the four window glazing processes; the bronze reflective glazing has 45.66% and 26.42% higher energy cost-saving potential compared to the tinted bronze and tinted green glazing, respectively. The bronze reflective glazing gives the highest air-conditioning demand and hence cost savings with the lowest payback periods (0.95 in SE) and adequate daylight factors. The four window glazing materials have also shown better daylight factors than the recommended values. The southeast orientation was observed to be the optimal orientation for the placing of glazing for maximum air-conditioning cost savings followed by the southwest and south. The results of this article can be used for the design of energy-efficient buildings. © 2020 Published by RERIC in International Energy Journal (IEJ).
