The answer to the previous question is A. Thermal imaging cameras give energy auditors a way to see if a home's "thermal envelope" is even and tight and there is minimal air leakage.

Answer and new question on next page.
Correction: This slide originally showed an incorrect thermal image. The proper image has been swapped in.
