Paper Abstract

We have developed a method for measuring R-values for large areas of building envelopes with thermography and contact sensors. The technique entails locating thermal extremes on a building surface with thermography. Contact sensors determine the R-values at these locations. A thermographic map provides the basis from which to interpolate R-values for all other locations within the area surveyed. This paper explains the interpolation technique we employed and demonstrates some of the difficulties of the method. Further experience will define the limitations of the technique more fully.
