A thermogram of a house shows high amounts of thermal energy around the windows but not around the roof. Which conclusion is best supported by the thermogram?
Correct Answer:
The windows are not energy efficient, but the roof is.
Explanation:
Thermography shows surface temperatures: hot areas on the image indicate where heat is entering or escaping. When you see a lot of thermal energy around the windows but not at the roof, it points to the windows being weak points for heat transfer. That means the windows are not energy efficient, letting inside heat escape, while the roof is better insulated and not contributing to heat loss. So the best-supported conclusion is that the windows are not energy efficient, but the roof is.
