WEATHERIZATION ENERGY AUDITOR SINGLE FAMILY Interpreting Infrared 1 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
Learning Objectives INTERPRETING INFRARED By attending this session, participants will be able to: Explain the strengths and limitations of infrared (IR) thermography. Interpret IR images as they relate to weatherization opportunities. Demonstrate how to assess the quality of installed weatherization measures using IR images. Use IR imaging in conjunction with blower door to track infiltration and direct air sealing activities. 2 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov

Summary INTERPRETING INFRARED IR imaging sees surface temperature only. Interpreting IR requires putting images in context. IR imaging cannot see through anything. Images are easiest to interpret when there is a large temperature difference, and they always require a trained technician for accurate interpretation. In conjunction with the blower door, IR imaging is a powerful tool for diagnosing infiltration and targeting air sealing activities. 13 | WEATHERIZATION ASSISTANCE PROGRAM STANDARDIZED CURRICULUM December 2012 eere.energy.gov
