THE EFFECT OF USING NANO-MATERIALS IN EXTERNAL OPENINGS ON ENERGY CONSUMPTION IN HOT DESERT CLIMATE

Abstract

Thermal insulation is one of the most significant solutions to reduce energy consumption in buildings. Therefore, using insulation materials with low heat transmission became an important issue. Recently, Nano-materials show great progress in the thermal insulation field in the hot desert climate. Several alternatives of Nano-materials in the glass windows were examined in this study. (Two layers from clear glass filled with the nanogel). It was found that it could save 11% of the total annual energy demand for cooling in comparison with the currently used glass in New Aswan buildings (Single glazing 3mm). This improvement percentage is considered twice the value of using double-glazing. This result is due to the low value of heat transmission for the nanogel in comparison with the air and argon. Moreover, the merged Nano-materials with argon and two layers of single glazing save about 26% of total annual energy in comparison with the current situation. Therefore, this study is considered an important attempt towards reducing energy consumption in the residential Building of New Aswan city.
