An existing home becomes Verified™ through a two-stage performance process designed to reduce building loads, optimize HVAC system design, and validate measured real-world performance.
The Verified™ framework focuses on creating accountability between predicted building performance and measured operational performance through Permanent Load Reduction planning, implementation, commissioning, and field verification.
Stage 1: Permanent Load Reduction Plan Verified™
The process begins with a Permanent Load Reduction Plan Inspection.
This evaluation combines:
- LiDAR-based Manual J® load calculation analysis
- detailed ACCA Manual J® load calculations
- building performance assessment
- airflow diagnostics
- infiltration evaluation
- and HVAC system analysis
to identify thermal discrepancies and performance deficiencies throughout the home.
The goal is to develop a predicted Permanent Load Reduction plan that reduces unnecessary heating and cooling loads before equipment sizing decisions are finalized.
This process may identify opportunities involving:
- air sealing
- insulation improvements
- duct optimization
- airflow balancing
- ventilation strategy
- humidity control
- and building enclosure improvements
The HVAC system is then specified based on the reduced-load design conditions created through the Permanent Load Reduction plan — not oversized rule-of-thumb assumptions.
Once the design pathway is established, the home enters the next phase of the Verified™ process.
Stage 2: Permanent Load Reduction Verified™
After the improvement plan is implemented, the home undergoes the Permanent Load Reduction Verified™ Protocol.
This phase validates actual measured system and building performance through:
- commissioning
- blower door testing
- airflow verification
- static pressure diagnostics
- duct leakage testing
- operational testing
- and MeasureQuick® performance benchmarking
to confirm the home and HVAC system perform according to the predicted load reduction strategy.
The goal is not simply to install new equipment.
The goal is verified HVAC performance based on measured operational data and validated building performance.
A Verified™ home is a home where:
- the loads were identified
- the reduction strategy was implemented
- the HVAC system was designed around reduced loads
- and the final performance was tested and verified in the field.
Because comfort, efficiency, and performance should not be assumed.
They should be predicted, verified, and proven
