Globally, buildings are responsible for approximately 40-45 percent of the total world annual energy consumption. Most of this energy is used for the provision of lighting, heating, cooling and air conditioning. The severity of the climatic conditions in the period considered and the rapid development and increased affluence of recent last decades are among the contributing factors. In particular, much research is focused on thermal energy storage due to heat transfer between the building envelope and the surrounding environment, in order to predict the rate of heat transfer and to develop minimisation strategies. However, the design and construction of modern residential buildings, which are heavily reliant on electrical systems for control of the internal built environment, are causing greater concern. Also, most of the environmental pollution caused by fossil energy are used that feeling the need to make use of alternative energy and efforts to minimize the energy dissipation. As a result, local attention is focused on improving energy efficiency for residential buildings. Among the various components of the building envelope, windows require a careful design because much of the heat dissipation occurs there. Windows are responsible for a disproportionate amount of unwanted heat gain and heat loss between buildings and the environment. Solar heat gain plays a major role in determining the thermal performance of a building and increasing or decreasing solar gains can be of crucial importance in design problems. Energy efficient windows should minimize thermal losses as well as air leaks; this is achieved in practice by a combination of different technical solutions, such as multi-layer glazing, low thermal conductivity gas fills, painted glass surfaces, low-emission coatings, edge spacers, and frame materials. An optimal window design with a suitable glazing compound can considerably reduce the energy consumption of air conditioning systems in the residential buildings. In commercial, industrial and public buildings, an optimum window design has the potential to reduce the cost of illumination as well as that of heating, ventilation and air-conditioning (HVAC). Computer simulations are commonly used to provide an expanded scope of systematic study and enable consideration of wide ranges and combinations of parameters. In this study, by computer modeling of the thermal dissipation of impact of tilt angle on the triple vacuum glazing with a thickness of 42 mm, in which a layer of Argon gas used to compare the three main technical factors that have been examined. These three main factors are heat transfer coefficient, relative rate of heat absorption and solar heat gain coefficient. The model of triple vacuum glazing is based on a commercial product that is available on the consumer market in Tehran. The results show that using triple vacuum glazing reduction more than 70 percent in energy dissipation And 60 degree glass on average in the southern facade of the building to optimize solar gain of solar energy with no apparent increase in thermal dissipation in energy of building.}, keywords = {Energy Waste,Triple Vacuum Glazing,Glass Modeling,heat transfer,Coefficient}, url = {https://www.ijashss.com/article_84359.html}, eprint = {https://www.ijashss.com/article_84359_1e342d8d38e0dd2d2330f95ca9e98948.pdf} }
