EXECUTIVE SUMMARY
Optimize before replacing.
SimEffi Score™68/100Optimization Opportunity
Annual Utility Spend$91,600
Near-Term Investment$64,500
Indicative Annual Savings$20,335
The building shows a stronger near-term case for controls, commissioning and operational optimization than for envelope replacement or major electrification. Aging rooftop HVAC should be coordinated with the planned capital cycle rather than justified on energy savings alone.

LIMITATIONS & NEXT STEPS
What still requires validation
- Site verification of equipment, controls and operating schedules
- Contractor or engineering validation for major HVAC, electrical and envelope projects
- Formal incentive eligibility confirmation before project commitment
- Measurement of post-project savings against a normalized baseline
