- Abstract
- Seasonal sub-surface ground temperature profiles and surface heat transfer were determined for the condition whereby one and more than one region of the earth's surface temperature were disturbed. The analysis was conducted by numerical integration using a closed form solution based on the Green's function. Monthly profiles of earth temperature isotherms under a house of 20' x 20' (6.1m x 6.1m) floor area and under a ground of six houses near a wooded area are presented. The heat losses calculated from this approach for square slabs of various sizes were compared with those derived from the recent analytical solution of Delsante et al. resulting in good agreement.
