Day light analysis of earth sheltered buildings for thermal comfort

Abstract

Earth is the cheapest and as well as commonly available material with enormous potential within it. The studies have been conducted for working out the energy usage of the earth-sheltered building as compare to a conventional above-ground building for thermal comfort with the help of energy simulation tools. The effect of soil cover and the thermal insulation of building envelop thickness, for the hot and dry climatic region will primarily be simulated. These models have been translated into computer software for excellence and efficiency in building design. During summer because of the more thermal inertia of soil, adjoining earth-sheltered building heat dissipation to the earth is much more which helps the air temperature to cool down naturally inside a building. The paper attempts to analyze the day lighting inside the building at different levels due to the presence of the windows on the wall. Demonstrate the lighting levels in the living spaces through computer simulations. The simulation is to be carried out at a particular sky condition on September 21 at 12. Also to do the analyze of glare in the case if the daylight is more than the required.
