Résumé
Extremely high outdoor temperature is a prominent feature of a hot arid climate. Hence designing a building that avoids heat gain from the outdoors is extremely strenuous in such a climate. Though several passive approaches have been studied and applied to control the indoor climate in hot arid regions, Earth sheltering is one of the most innovative and least explored approaches. The research work aims to provide an architectural solution to issues of heat gain by improving resistance to a building`s heat gain. Earth Sheltered Buildings are capable to maintain indoor temperatures with minimum fluctuations below the ground. The methodology includes studying various examples done in this field so fari.e. literature review studies, then developing simulation tools, working on various design options and choosing the best possible example, and finally doing analysis to arrive at guidelines. The purpose of the entire study is to explore the possibilities for conservation of energy along with design options of Earth-sheltered buildings. Such buildings have significant advantages over other above-ground buildings that have been discussed in the report. Earth-sheltered buildings were initially and fore mostly developed for shelter, heat, and protection for the earliest human dwellers. The study is about various Architectural layouts of the Earth-sheltered residential buildings. Further, the best-concluded layout has been analyzed for energy savings and daylighting. A model for the same was prepared and examined by placing it on heliodon. This was done to study the sun path effect on the structure for validation. Finally, it was concluded that these non-conditioned buildings can be the best alternate for providing thermal insulation. Since the earth has a thermal mass & while going below 4meters temperature fluctuations become negligible, thus making the structure cool. Though the construction cost of such buildings is higher, there are long-run energy-saving benefits along with other advantages.
