Building Envelope Inspection -Home Energy Audit
The home energy auditor you choose should check all three parts of the building envelope:
- The integrity of the air barrier
- Adequacy of insulation levels
- Alignment of insulation with the air barrier
When insulation is installed without an air barrier, it won’t do its job. Most types of insulation do not stop air leakage, so one thing the energy auditor will do is look for proper alignment of the insulation and air barrier throughout the house. The energy auditor will also look for proper levels of insulation (wherever visible) and check for the existence of insulation behind walls. They’ll check the integrity of the air barrier in two ways: a visual inspection and a Thermal Image.
