The ERI pre-drywall inspection verifies that the home is being constructed according to the intended building performance, energy modeling, and HVAC design strategy before the walls are closed and critical components become inaccessible.
Within the Whole Home Performance Verified™ pathway, the pre-drywall inspection is a key checkpoint in the Installed Per Design™ process.
The goal is to confirm that the home’s predicted performance pathway still aligns with how the home is actually being built in the field.
During the ERI pre-drywall inspection, the home is evaluated for:
- insulation installation quality
- air sealing details
- framing conditions
- HVAC duct layout
- ventilation pathways
- airflow planning
- thermal boundary continuity
- moisture management details
- and overall installation consistency with the ERI energy model and HVAC design
This inspection helps identify performance deficiencies before drywall installation makes corrections significantly more difficult and expensive.
The pre-drywall inspection may also verify:
- duct sealing integrity
- mechanical penetrations
- pressure boundary alignment
- insulation depth and coverage
- ventilation system rough-in
- and building enclosure continuity
to help ensure the home can achieve the predicted operational and energy performance targets established during the Design Verified™ phase.
Within the Verified™ framework, the ERI pre-drywall inspection is not simply a code inspection.
It is part of a broader building performance verification process designed to create accountability between:
- the energy model
- the HVAC design
- the installation process
- and the final measured performance of the home.
The purpose is to reduce the gap between predicted and actual performance before the home reaches final commissioning and operational verification.
Because once drywall is installed, many performance deficiencies become harder to identify, harder to correct, and more expensive to fix.
The ERI pre-drywall inspection helps ensure the home is still on the pathway toward verified HVAC and building performance
