We're fascinated by new gadgets. Like Toad in Wind in the Willows , who was left delirious with envy when his wonderful newer horse cart was run off the road by an even newer and more wonderful horse-less car, we find new tools seductively attractive. Infrared thermography allows us, with true Buck Rogers finesse, to practically see through walls. While thermography is still primarily used for crew and auditor training, a second wave of use is finally starting to reach weatherization crews. The investment required for equipment is significant, but returns from a well-designed training program can be worth many times that in increased productivity and effectiveness.
Thermography is especially powerful when it's used on every single building in a program.
Energy auditors can work more quickly to locate and prioritize air leakage, and to provide a framing map for sidewall crews. With thermography, crew efficiency increases and job time decreases. One option is for state entities to purchase the cameras, and then loan or lease them out. However, careful attention should be given to the logistical details of sharing, or the savings can evaporate. Too often programs neglect this important first step with costly consequences.
