Your building's energy, managed — and working for you.

See your building's real energy exposure — what you owe, what to fix, and a clear path to handle it. Computed straight from the statute and your own utility data, so you can plan ahead instead of react.

The situation

Two things are happening to your building at once.

Cities now put real dollar penalties on energy use — and even where they don't, commercial power prices are climbing faster than they have in years. Most owners and boards can't say what either one will actually cost them. You should know your real exposure before you owe a cent of it.

What BuildingFi does

Everything about your building's energy — handled, and improving.

Manage

Your filings and bills, in one place.

We pull from your city's filings and your utility data and keep your energy record straight. In a regulated city, we prepare the filing and keep you compliant — a licensed engineer seals and submits it. Anywhere else, we keep your bills and benchmarks organized and ready.

Optimize

Know what's worth fixing — and whether financing it beats the penalty.

Every upgrade ranked by dollars saved per dollar spent, modeled against your actual energy use and your city's caps. Where it pays, finance it through C-PACE with no upfront capital, repaid on your property tax bill — and we'll model whether that yearly payment comes in under the fine before you commit.

Stay compliant, avoid the penalty, hit the deadline.
See how you rank against similar buildings nearby — and what's worth upgrading as rates climb.
Why now

You can't control the rate. You can control how much you buy.

Commercial electricity is up double digits and still climbing — driven by AI data-center demand straining the grid. You can't change the price per kilowatt-hour. You can change how many you need. Every kilowatt-hour you don't buy is worth more this year than last.

How we compute your number

We compute your number straight from the statute.

A penalty is only as good as the math behind it. Penalties are figured from an emission factor — and most online estimates use the wrong one (ENERGY STAR's 0.000408) instead of the factor the law actually names (Table 320-3, 0.000288962). On a real 2.4M-sqft NYC office that is the difference between a common estimate and the real number. We compute on the statute and show you every line, so the figure you act on is the figure you can defend.

Common estimate — ENERGY STAR eGRID factor (0.000408 tCO₂e/kWh)
$9,094,861
130,918,000 kWh × 0.000408 = 53,415 tCO₂e
Over cap by 34,005 tCO₂e × $268 = $9,113,340
Not the statutory factor. Overstates exposure 1.41×.
Statute — NYC Admin Code §28-320.3.4, Table 320-3 (0.000288962)
$4,485,600
130,918,000 kWh × 0.000288962 = 37,831 tCO₂e
Over cap by 16,737 tCO₂e × $268 = $4,485,516

Five steps from unknown exposure to a compliant building with no upfront capital required.

01 · DATA

City filings

We pull from NYC DOF, DOB, and ENERGY STAR LL84 benchmarking data. Updated continuously.

02 · COMPUTE

Statutory math

Computed on the factor the law actually uses — Table 320-3 for NYC. Every line auditable and citable.

03 · PLAN

Ranked retrofit plan

Upgrades ranked by dollars saved per dollar spent, modeled against your actual energy use and caps.

04 · FUND

C-PACE financing

100% of retrofit cost financed. Fixed-rate to 30 years, repaid on the property tax bill, non-recourse.

05 · SEAL

PE / RA filing

A licensed engineer arrives already knowing your numbers, scopes the work, and files the compliance plan.

Financing

Pay the penalty forever, or finance the fix once.

The penalty recurs every year and rises when Phase 2 caps tighten in 2030. C-PACE converts the capital project into a tax assessment repaid from energy savings. We model both options against your actual building before you commit.

Option A · Status quo

Pay the penalty

$4.49M
per year · every year · no asset created
  • Penalty recurs annually with no asset created
  • Rises when cap tightens in 2030
  • Drags NOI and depresses value at sale or refi
  • Still requires a PE/RA compliance filing
Option B · C-PACE retrofit

Finance the fix

$0
upfront · illustrative: ~$6.9M financed over 25 years
  • 100% of project cost financed, no money down
  • Fixed-rate to 30 years, repaid on property tax bill
  • Non-recourse — no personal guarantee required
  • Transfers with the building on sale or refinance
  • Annual assessment modeled against your energy savings

Your building, working for you

Compliance is the start.

Once your systems are upgraded, BuildingFi connects to your building's sensors and helps you run them — optimizing energy use on your terms, and turning spare capacity into income through demand-response and grid programs. The liability you started with becomes an asset on your balance sheet.

Recommendations and automation you approve — decisions are never made over your head.
