Performance assessment of passive heating and cooling techniques for underground shelter in equatorial climate

Underground shelter serves as a specialized building structure that can provide either heating or cooling to occupants during different climates depending on the requirements. In this study, the CFD model of the 3D underground shelter was simulated at different seasons of the year in Malaysia. Initi...
