Paper Abstract

An aerial infrared survey of a community was made using quantitative techniques designed to measure the roof surface temperature and the net heat flux from the roof structure. The aerial heat loss values were computed on over 1,000 structures from which a subset of 100 were selected for additional analysis using an on site visit. The aerial and structural data (i.e., insulation levels and inside air temperature) obtained from the on site visits are shown to correlate quite well with residual errors of less than 7 watts/m2 . These results indicate that meaningful measurement of different levels of heat loss can be quantitatively measured using wholely airborne aerial survey techniques. The technique described accounts for atmospheric and emissivity effects on the thermogram data as well as convective and radiational losses from the roof surface.
