Commercial buildings built prior to the current period of soaring energy costs have typically been underinsulated and increasingly expensive to operate. Current methods for installing retrofit insulation in these buildings may have limitations due to severe climates or high interior humidity conditions. These factors can lead to condensation at the roof deck. The ability to predict when problems will occur depends largely on the understanding of the heat and mass transfer mechanisms and the coupling between them.

Experimental and analytical models have been developed to permit the evaluation of retrofit roof insulation systems in terms of their potential for condensation. This method is now being used to evaluate various commercial roof insulation systems. Some preliminary results demonstrating the transient predictions and measured values available from this procedure are displayed. Good agreement between the experimental and analytical models is shown. Refinements and improvements in the procedure are suggested.
