Which of the following is NOT a typical component of an energy audit?

In the context of an energy audit, a cosmetic inspection of the exterior focuses on the aesthetics of a building rather than its energy efficiency. Energy audits are primarily concerned with evaluating the performance and efficiency of systems that directly impact energy consumption, such as heating and cooling systems, insulation levels, and air leaks.

Checking heating and cooling systems is crucial because these components significantly influence energy usage and comfort levels within a building. Inspecting insulation levels is essential because adequate insulation helps maintain energy efficiency by minimizing heat loss in the winter and heat gain in the summer. Measuring air leaks is vital, as drafts can lead to increased energy costs and reduced comfort.

In contrast, a cosmetic inspection does not pertain to the functional efficiency of the building. While it may identify issues that could eventually affect energy performance (like unpainted surfaces or peeling paint), it does not focus on the operational aspects necessary for a thorough energy audit. Thus, performing a cosmetic inspection of the exterior is not a typical component of an energy audit.
