CALCULATION OF BELOW-GRADE RESIDENTIAL HEAT LOSS LOW-RISE RESIDENTIAL BUILDING G.P. Mitalas, P.E. ASHRAE Fellow ABSTRACT A simple calculation makes it possible to determine the maximum rate of below-grade heat loss from a basement and the total heat loss over the heating season. The procedure accounts for the variation of below-grade heat loss

Conversely, if the concrete masonry units have compressive strengths of 2,800 psi (19.3 MPa), then the maximum f' m used in design would be 2,000 psi (13.8 MPa) if Type M or S mortar were used.
