No results have been reported in the published literature on the influence of neighboring buildings on foundation heat transfer. In this Note, a simplified model of two adjacent slab-on-grade floors is developed in order to understand and estimate the effect of the presence of a building on the heat loss from a foundation of another building. In particular, the solution presented in this communication represents the first analytical solution to steady-state heat conduction problem under two adjacent slab-on-grade floors with horizontal and uniform insulation. The proposed model can handle any size for the slabs and any distance that separates the two slabs. A water table effects is also considered in this model. The soil temperature field is obtained and analyzed using the Interzone Temperature Profile Estimation (ITPE) technique (Krarti, 1989; Krarti, Claridge, and Kreider, 1988). A discussion is presented on the effect of the distance separating the neighboring slabs on soil temperature distribution and on the total slab heat loss.
