Is a heat pump worth it
for your building?

Redo your building's HVAC — enter your address and energy costs for a commercial-scale analysis with equipment options, per-square-foot metrics, O&M comparison, MACRS depreciation benefits, and every available incentive.

Energy Costs — your annual spend
$

Total annual electric bill. Check your utility account for 12-month history.

$

$0 if all-electric. For gas, check your gas utility's 12-month summary.

I don't have energy bills We'll estimate your energy costs from DOE CBECS building energy benchmarks for your building type and climate zone.
4
Tax & Organization Details

Tax-exempt orgs can receive ITC via direct pay (elective pay) instead of tax credits.

%

Federal 21% + state corporate tax. Used for MACRS/Section 179 depreciation benefit.

Financing
Include financing in analysis? Model a commercial loan — shows monthly payments vs. energy savings and adjusted payback
These inputs aren't required — reasonable defaults are used when left blank. They improve estimate accuracy for commercial buildings.
A
Building Envelope

Affects heating/cooling load estimates. Most pre-2000 commercial buildings are "average" or "poor".

B
Solar & On-site Generation
No solar
Existing solar
Planning solar

Commercial solar can offset a significant portion of heat pump operating costs, dramatically improving payback.

C
Electricity Rate
Commercial rates differ from residential. The default rate uses EIA residential state averages. For commercial buildings, enter your actual blended $/kWh rate from your utility bill for best accuracy. Commercial rates are typically 10–30% lower than residential.
$/kWh

Find your effective rate on your bill: total $ ÷ total kWh. Commercial rates are typically $0.08–$0.18/kWh depending on region.

Fuel & Electricity Escalation

E
Electrical Service
Electrical service upgrade may be required. Converting to a commercial heat pump system may require upgrading your electrical service to handle the additional load. For buildings with older 200A single-phase service, a 3-phase 480V upgrade typically costs $5,000–$15,000. Newer buildings with adequate 3-phase service may need no upgrade.
No — adequate service
Yes — add ~$10,000

Assumptions & Methodology ▼
How This Is Calculated

• Heat pump heating efficiency calculated using manufacturer COP ratings, adjusted for your local climate using piecewise temperature band model. Annual heating energy derived from your energy bills or DOE CBECS EUI benchmarks.

• Install costs are regionally adjusted using BLS May 2024 HVAC labor wage data for your state. Commercial systems benefit from economies of scale at larger sizes. Get 2–3 quotes from certified commercial contractors for accuracy.

• O&M costs based on ASHRAE/BOMA industry benchmarks for commercial HVAC maintenance contracts by system type and size.

• Grid carbon intensity uses EPA eGRID 2023 state-level output emission rates. Fuel combustion CO₂ values use EIA/DOE emission factors per fuel type.
