DRAFTCommercial Thermal Modernization Standard
September 2026 · Model program design
A delivery standard for cooling, water heating, refrigeration, thermal storage, solar, batteries, and controls in businesses and essential-service facilities. It begins with service requirements and load data, then pays for verified efficiency, resilience, and maintenance outcomes.
Policy rationale
Grocers, clinics, food businesses, schools, farms, and small manufacturers do not experience energy as an abstract commodity. Cooling, refrigeration, hot water, communications, and safe indoor conditions are operating requirements. HGIA already recognizes several relevant commercial measure categories, including HVAC, water heating, thermal storage, refrigeration, motors, building-envelope work, and solar.
PMF proposes an essential-service-first delivery model. Each site starts with a critical-load inventory, interval data where available, equipment condition, tariff, site constraints, and maintenance capacity. The project then defines its service level, energy objective, resilience design, permitted controls, and financial terms. A generic claim that a battery or heat pump preserves operations is not accepted without a critical-load circuit and duration analysis.
The capital stack should use existing on-bill and C-PACER pathways where appropriate, plus confirmed incentives and performance contracts. Grid-services revenue may improve the economics, but it should not be booked as guaranteed operating income until a tariff and contract support it. Public or ratepayer funds should require commissioning, maintenance, and portfolio reporting.
Evidence and implementation
Implementation dossier: commercial thermal modernization
Commercial modernization should buy safe useful thermal service, lower operating cost, and maintainable resilience—not a generic equipment bundle or a nameplate claim.

Begin with the service the facility must protect
Evidence & PMF analysisTechnical guidance · source context
Federal building guidance treats grid-interactive efficiency as a co-optimization of building service and grid value. For Hawaiʻi facilities, start with food temperatures, humidity, clinical conditions, hot water, process heat, communications, and comfort—not a generic equipment claim. A heat pump’s coefficient of performance is not a site-specific savings or resilience guarantee.

PMF recommendation
PMF recommendation: inventory critical circuits, load profiles, temperature and humidity bands, cold-chain or process limits, operating hours, tariff, equipment condition, and maintenance capacity before selection. Group projects by application—such as hospitality hot water, grocery refrigeration, clinics, farms, or process heat—rather than force one retrofit recipe.
Procure integrated, maintainable services with local capacity
PMF recommendationA public solicitation should describe delivered service, peak profile, resilience duration, space and electrical constraints, maintenance, commissioning, training, and data. It should allow HVAC, water heating, refrigeration controls, heat recovery, thermal storage, solar, batteries, envelope work, and electrical upgrades to compete as one coordinated design. Keep eligibility technology-neutral.
Bidders should provide an island-based workforce plan: licensed trades, apprenticeships, local parts, emergency maintenance, safety, warranty administration, and owner training. Evaluation should reward local maintenance capacity, not only low first cost. The selected provider should own integration faults across thermal, electrical, controls, and storage systems.
Finance the installed service on conservative cash flow
Evidence & PMF analysisPublished terms · source context
HGIA’s commercial GEM$ pathway covers eligible nonprofits, small businesses, multifamily rental projects and commercial tenants, subject to rate-schedule, contractor, measure and savings requirements. Tenants need owner approval. This is distinct from household eligibility and does not guarantee the economics of every commercial retrofit.

HI C-PACER offers a separate property-assessment structure for qualifying nonresidential and larger multifamily properties. It can finance permanently affixed improvements including heat pumps and storage. The assessment is senior to mortgages but junior to property taxes; existing mortgage-lender consent is required. It is financing, not a rebate or a blanket route for portable equipment.

PMF recommendation
PMF recommends separating facility ownership, lender security, warranties, service contracts, and provider-owned batteries or controls. Base underwriting should exclude uncontracted grid revenue and stress-test any enforceable receipts for counterparty failure. Providers should bear commissioning and correction risk within their scope; performance fees stop while agreed service is outside its band. Support should cover audits and corrective work as well as installation.
Do not dispatch comfort, humidity, or food safety below safe limits
PMF recommendationBefore a thermal asset joins grid services, document service bands, sensors, calibration, manual override, recovery time, rebound, warranty limits, and escalation contacts. A control may pre-cool, pre-heat water, shift defrost, or use thermal storage only while preserving approved temperature, humidity, food-safety, health, and process requirements.
M&V should record useful service alongside electricity: thermal energy where feasible, temperature and humidity excursions, food incidents, alarms, complaints, peak relief, and recovery. It must audit performance without exposing proprietary operations. A safety or quality excursion pauses automated dispatch pending documented correction.
The same useful heat can require less electricity
A physical illustration holding delivered heat constant while coefficient of performance (COP) changes. It is not measured equipment performance at a Hawaiʻi site.
| COP | Useful delivered heat | Electricity required |
|---|---|---|
| 1 | 6 kWh thermal | 6 kWh |
| 2 | 6 kWh thermal | 3 kWh |
| 3 | 6 kWh thermal | 2 kWh |
| 4 | 6 kWh thermal | 1.5 kWh |
Electricity = useful delivered heat ÷ COP. The initial 6 kWh thermal comparison requires 6, 3, 2 and 1.5 kWh at COP 1, 2, 3 and 4. Actual COP varies with temperatures, controls and installation. Heating efficiency relative to resistance is not an equivalent savings claim against an existing efficient air conditioner.

Build a portfolio through application-specific gates
PMF recommendationPMF recommends short pilots by application class, then independent comparison of installed cost, service quality, bill effect, maintenance, workforce response, grid value, and safety. A successful hospitality hot-water pilot does not automatically authorize food cold-chain or process-heat deployment; each needs its own commissioning threshold.
Expand only on demonstrated useful service, not tonnage sold. A public scorecard should show verified savings, affordability, promised outage performance, event availability, local jobs, warranty calls, and complaints. Stop designs that erode service quality or shift unrecoverable risk to customers.
