A heat loss survey was performed on five typical Air Force Base buildings with an infrared camera system two with wood frames and wood clapboards, one with wood frame and aluminum siding, and two of cinder block construction with brick veneer. A walk-through inspection was also performed on three of these buildings chosen by project monitors for retrofitting. This report presents thermograms typical of the heat loss problems in each of the five buildings along with a complete explanation of each thermogram. The purpose of the report is to serve as a basis upon which Air Force civil engineers can plan a future retrofit program for the buildings surveyed and write a set of specifications incorporating thermography. Typical thermograms show heat loss from large, single-pane, steel-frame, projected windows, which in one building account for 50 of the total wall area. Infiltration losses through framing spaces for all windows are evident. Heat patterns from precast concrete floor slabs and radiators under the windows showed up clearly. Ribs in uninsulated door panels were clearly seen as well as leakage around the doors. Heat loss through the roof of a one-story duplex was easily recorded from the ground using the infrared camera system. Thermographic comparisons between windows with storm sashes and a picture window insulating glass were made. Heat was found escaping from slab foundation vents and gable vents. Author
