Passive solar structures commonly utilize earth bermed walls to enhance energy conservation in spite of the lack of well-validated guidelines capable of quantifying their expected thermal performance. In an effort to provide some added insight on the thermal response of earth bermed structures, a transient two-dimensional model sufficiently general to accommodate numerous earth sheltering configurations under variable boundary and soil conditions has been developed. This allows accelerated investigation of systems which, due to their thermal properties, are transient in nature with extremely long time constants. The present model considers time dependent soil properties, different types of below-grade structure configurations, and various types, thicknesses and locations of insulation. Heat loss and gain through the exterior building envelope versus location and time of year are given as functions of construction materials, insulation and soil geometry.
