A general solution for the steady-state heat conduction problem under a basement located at some distance from a slab-on-grade floor is presented. A water table is assumed to exist at a finite depth from the soil surface. A semi-analytical solution is derived for the general case where both -- basement and slab -- are uniformly insulated. The soil temperature field, and the total heat loss for basement and slab-on-grade floor are obtained using the Interzone Temperature Profile Estimation (ITPE) technique. The temperature profiles resulting from different insulation configurations at various distances separating the basement foundation from the slab-on-grade floor are analyzed. The effect of varying the distance between the two buildings on the total ground heat loss of all surfaces (wall and floors) is discussed in detail.
