27 January 1981 Measuring Building R-Values For Large Areas
Author Affiliations +
We are developing a method for measuring the R-values of large area of building envelopas. This is a summary of progress to date. We locate temperature extremes on the building surface with an infrared videocamera, determine the R-values at those locations with contact thermal sensors, and interpolate R-values for all other locations from the thermograms.
