Abstract
The steady-state methods currently used to calculate floor heat loss are examined, and the errors which these produce in comparison with more accurate analytic solutions are illustrated. A simple model of flow is then proposed, which splits the flow into the three components. These are the steady-state flow and annual cyclic flow to the outside, for which analytic solutions are given, and the short term vertical flows within the floor resulting from internal temperature fluctuations. A worked example is presented for a typical case.Keywords
