Results of a thermographic study of roof surface temperature and heat loss are presented. The major finding is that a technique is demonstrated for obtaining quantitative temperature and heat transfer measurements from a thermogram using a thermally controlled reference surface within the area surveyed. The presence of the reference surface is shown to permit calculation of heat transfer rate with a quantifiable level of uncertainty. The present work also demonstrates that the representation of grey tone imagery in digital and graphical formats can be useful for both qualitative and quantitative purposes in energy conservation.
