Abstract: The building’s main function is to provide thermal comfort to users. However, it started to be harder to maintain high thermal comfort without using the mechanical equipment, which consumes large amount of energy. The earth-sheltered buildings started to be spread all-over the world to solve this contrariness, by reaching high thermal comfort with minimal use of energy consumption. The most energy saving potential benefit of the earth sheltering is to gain low fluctuation and steady state of the internal temperature. Besides, flattening the peak temperatures of daytime and nighttime. That is the most desired benefit especially at the hot-arid climates, where fluctuations are very high. However, little number of deep researches and applications were found about earth sheltering in hot-arid climates. This research chose Egypt as a case study to measure the basements’ thermal performance using real measurements of three different structure types, and simulation programs to analyze thermal comfort. It found that basements are more stable than conventional buildings, and can provide thermal comfort with low temperatures fluctuations, if high humidity could be controlled with innovative designs. Finally, the research presents general guidelines for application, as an approach for the complete stand-alone earth-sheltered buildings’ simulation and application at Egypt.
