Free LL97 penalty calculator
Estimate your exposure in ten seconds — modeled from 12,700+ real LL97-covered NYC buildings. Then get your building's exact numbers by email, free.
Modeled from the distribution of 12,700+ real NYC buildings in our dataset. This is what a typical building of this size and type faces — your building's actual number depends on its fuel mix, systems and filings.
Your address + email. Your building's real figures, not the typical ones. No drip campaign.
Not just the number. A number on its own frightens a board into tabling the discussion for another quarter — so the report is written to be acted on, and forwarded:
Your exact figures. Current emissions, your cap for each compliance period, the projected annual penalty, and cumulative exposure through 2030 — pulled for your specific building, not the typical one.
Which lever is actually available to you. If you're steam-heated, we'll say plainly that RECs won't move your number yet — and what will.
Whether you're inside the credit window. Equipment installed before 2027 earns double Beneficial Electrification Credit. For some buildings that's the difference between a manageable plan and an expensive one.
Your filing position. Clear, late, or facing the August 29 extension deadline.
Estimates are modeled from public City benchmarking disclosure. A filed compliance report requires verified building data and a qualified filer — a separate engagement we'll explain if you want it.
Size and building type — see what a typical building like yours faces. Free, anonymous, in your browser.
Your address and email. That's the whole ask.
Your specific figures, in your inbox — written to be forwarded straight to the rest of your board.
No drip campaign, no sales sequence. If the report is all you needed, that's a fine outcome.
We model whole portfolios against 2026, 2027 and 2030 in one pass — and tell you which buildings actually carry the risk.
