Heat loss from a solid floor: a new formula.

Author(s) : DAVIES M. G.

Type of article: Article

Summary

It is pointed out that Macey's formula, used in the CIBSE Guide to calculate the heat loss from a solid uninsulated ground floor slab, is unsymmetrical in its handling of the floor length and breadth L and B, and further that it implies the existence of a volume of perfectly insulating material embedded in the base of the wall (thickness W). Both flaws are avoided in a simple expression for heat loss which involves the floor dimensions grouped as LB/W(L + B). The expression provides an excellent approximation to an exact expression for heat loss due to Delsante, Stokes and Walsh.
