Which tool is commonly used to measure temperature differences in a building’s envelope?

• A. Moisture meter
• B. Infrared camera
• C. Thermometer
• D. Barometer

Answer: (B)

The tool commonly used to measure temperature differences in a building’s envelope is an infrared camera. This device captures thermal images that visually represent temperature variations across different surfaces of the building. By identifying areas of heat loss or gain, an infrared camera aids professionals in detecting insulation deficiencies, air leaks, and other thermal performance issues. Its ability to produce immediate and clear visual data makes it invaluable for building analysts who are tasked with evaluating energy efficiency and ensuring occupant comfort. Other tools have different primary functions: a moisture meter specifically measures moisture levels in materials, which can relate to energy efficiency but does not directly measure temperature differences. A thermometer is used to measure air temperature but lacks the capability to assess temperature variations across surfaces comprehensively. A barometer measures atmospheric pressure, which is important for certain environmental assessments but not directly relevant to evaluating a building's thermal envelope.
