Comparison of shallow basement thermal performance for different regions of Morocco using a three-dimensional heat transfer analysis

A three-dimensional numerical model was built to estimate the heat transfer between the soil and a shallow basement in four different climates (cold, temperate, semi-arid and arid climates) for, respectively, conditioned and unconditioned cases. The governing heat transfer equation in soil and basem...
