ABSTRACT

The evaluation of time delay and dimensionless factor provides a measure of the developed indoor thermal conditions and from an energy point of view, the possibility of reducing the energy load demands. For this Investigations were carried out on the time delay and dimensional factors of a clay building. In the computations, the periodic boundary and the convection boundary conditions to
the outer surface of the wall were applied to the one dimensional transient heat conduction equation. A set of clay building was used in the analysis. The computations were repeated for the five different clay walls thickness and the
influence of the wall thickness on time delay and dimensionless factor were investigated. It was found that thickness of wall has a very pronounced exponential relation with the dimensionless factor and time delay.
