A CPACE lender requires an 'independent engineer review' of a proposed efficiency project. What is the primary purpose of this review?
Answer: To verify that projected energy savings are technically sound and support loan repayment
Independent engineer reviews validate that savings projections are credible and sufficient to cover CPACE assessment payments, protecting lenders and property owners.
Which ASHRAE energy audit level provides the most detailed analysis typically required for large CPACE projects?
Answer: Level 3 — Detailed Analysis of Capital-Intensive Modifications
ASHRAE Level 3 audits include detailed engineering calculations, equipment monitoring, and financial analysis sufficient to support capital-intensive CPACE project decisions.
A property owner finances a CPACE efficiency upgrade that reduces annual energy costs by $80,000. The annual CPACE assessment is $60,000. What is the annual net cash flow benefit?
Answer: $20,000
Net annual cash flow = energy savings minus assessment payment: $80,000 − $60,000 = $20,000 positive cash flow.
In CPACE efficiency projects, 'measurement and verification' (M&V) follows which industry-standard protocol?
Answer: International Performance Measurement and Verification Protocol (IPMVP)
The IPMVP provides standardized options for measuring and verifying energy and water savings after efficiency improvements are installed.
A CPACE project upgrades a commercial building's rooftop HVAC units to high-efficiency models. The key efficiency metric for these units is:
Answer: Energy Efficiency Ratio (EER) or Integrated EER (IEER)
EER and IEER measure cooling output (BTU) per watt of electricity consumed and are the standard efficiency ratings for commercial rooftop cooling equipment.
Which CPACE-eligible water efficiency measure also reduces energy consumption by lowering hot water demand?
Answer: Low-flow pre-rinse spray valves in commercial kitchens
Low-flow pre-rinse spray valves reduce hot water use in kitchens, cutting both water heating energy and water consumption simultaneously.
A CPACE project installs a building automation system (BAS). Which capability directly contributes to energy efficiency?
Answer: Automated demand-controlled ventilation based on CO2 sensors
Demand-controlled ventilation (DCV) reduces fan energy and conditioning loads by adjusting fresh air delivery based on actual occupancy measured by CO2 sensors.
