Economic, Environmental And Energy Loss Investigation Of Multi Glazed Windows

Abstract

Design and selection of windows has a significant impact on the building energy loss. The proper windows not only determine the energy waste, but also has a strong effect on the initial cost, CO₂emission, and embodied energy. In this research the effect of multi glazing window glass and cities average monthly temperature, on the energy waste, initial cost, payback period, CO₂ emission, and embodied energy was investigated. The use of triple glazed window, significantly decreased the energy waste and related cost. It was observed that in the first installation, the capital payback period in the range of 0.7 to 2.6 years, therefore in the first installation economically it is strongly recommended to use a double or triple glazing window.
