The designs of heating and cooling systems are typically based on heat transfer under steady-state conditions. In desert regions, however, there are large changes during a 24-hour period and the steady-state approach becomes inapplicable. An analysis of transient heat transfer through insulated walls is presented for three different cases. The results indicate that cooling loads for buildings are smaller for insulation placed on the outdoor façade than for insulation placed on the indoor façade.
