When should a moisture test be conducted during an energy audit?

Conducting a moisture test during an energy audit is essential for identifying potential moisture issues or evaluating the performance of the HVAC system within a building. This is necessary because moisture problems can lead to structural damage, mold growth, and decreased indoor air quality, all of which can compromise not only the building performance but also the health and safety of its occupants.

When assessing a building's performance, understanding the interactions between moisture, insulation, and HVAC systems is vital. A moisture test provides critical data about humidity levels, the presence of water leaks, and the overall health of the air within the building. Addressing moisture issues is a fundamental aspect of maintaining a comfortable living environment and ensuring the longevity of the building structure itself.

While conducting moisture tests before changes, after installing new appliances, or during a final inspection may provide some insights, these are not the optimal times for conducting moisture tests as part of an energy audit. Ideally, tests should be done as part of the assessment when the factors influencing moisture levels, such as ventilation, insulation, and existing HVAC performance, can be accurately evaluated and addressed. This approach not only helps in pinpointing current issues but also assists in making informed decisions about necessary improvements during the audit process.
