Describe what an infrared camera does in the context of building performance.

An infrared camera plays a crucial role in assessing building performance by detecting temperature differences in building envelopes. This technology is essential for identifying areas where heat loss or gain occurs, allowing for a detailed analysis of the building's thermal efficiency.

By visualizing temperature variations, the infrared camera can reveal issues such as insufficient insulation, air leaks, and thermal bridging. These problems can lead to increased energy consumption and reduced comfort levels within the building. Identifying these discrepancies enables professionals to target specific areas for improvement, enhancing the overall energy efficiency of the structure.

While measuring air quality, enhancing decorative elements, and calculating energy savings from insulation are important aspects of building performance assessments, they do not directly pertain to the primary function of an infrared camera. Its primary utility lies in thermal imaging, making it an invaluable tool for diagnosing energy performance issues in buildings.
