Abstract: Nine buildings at Ft. Devens were the object of a study employing heat flux sensors, thermocouples, a computer controlled data acquisition system and infrared thermography. The purpose was to measure the R-values of those buildings to determine their economic potential for improved insulation. The sample included four frame buildings, two masonry bulldings, and three frame buildings with brick facing. The technique for measuring R·values proved repeatable and accurate within 15%. Sampling a small representative sample sufficiently characterizes the entire stock of buildings. Measurement is more important for poorly insulated buildings, since the beginning R·value has a drastic impact on the budget for a cost-effective reinsulation project. At Ft. Devens, installing an external Styrofoam insulated system on concrete block barracks has a savings-to-investment ratio of about 1.4.
