Abstract
In this paper, presented at CRRELs First International Conference on Snow Engineering, the results of a one-dimensional steady state heat transfer model indicate that the temperature increase between eave and ridge of cavity air in a double roof is small. This has important implications for mitigating eave ice damming. Appropriate air cavity depths must b eused for long roofs and varoius outside temperatues. Preliminary experimental results tend to substantiate the analytical approach. Further refinements include an improved analytical model and enhanced experiemnts to increase precision of temperature measurements and measure the velocity profile in the air cavity.
