The ERI Pre-Drywall Inspection is where load calculation assumptions are field-verified against actual construction before walls are closed. This step is mandatory for new homes seeking Verified Home™ certification.
The ERI Pre-Drywall Inspection verifies:
- Insulation type, depth, density, and installation quality in all thermal assemblies
- True R-values based on installation and assembly, not just labeled batts or nominal values
- Window and door U-factor and SHGC using verified manufacturer data
- Ductwork location, insulation level, and relationship to the thermal boundary
- Thermal boundary alignment at walls, rim joists, ceilings, and floors
- Ventilation strategy and key duct routing before concealment
These verified values are fed back into the Manual J load calculation and ERI model so the design matches the real house.
