Your LL97 penalty isn't a 2030 problem. It's an annual invoice that already started.

Compliance advisory for co-op and condo boards — the benchmarking, the filing, the incentive money, and the plan your shareholders will actually approve.

Boards weren't built to run carbon compliance.

a.

The report sits unread

A board commissions a one-off energy audit. A PDF arrives. It gets filed in a shared drive and the discussion is tabled another quarter. The number was never the hard part.

b.

The big firms priced you out

Consultancies built for institutional portfolios assume a capital planning team and a sustainability budget. Their deliverables land on a board table and paralyze the room instead of moving it.

c.

So the penalty just runs

Meanwhile $268 a ton accrues every single year. A building 200 tons over its cap bleeds $53,600 annually — money that could have funded the retrofit that ends the problem.

02

RECs are a real lever in your compliance plan — we source them and structure them, not just explain them.

Renewable Energy Certificates offset Scope 2 emissions — the electricity you pull off the grid — under NYISO Zone J and NYSERDA's Tier 4 program. We run REC work two ways: sourcing certificates directly from the open market when the timing and price make sense, and structuring a bespoke arrangement when your building's mix calls for it.

They're one part of a larger plan, not a standalone fix. If your building burns gas or oil for heat and hot water, that's Scope 1 — RECs don't offset it directly, so we sequence sourcing and structuring alongside the retrofit and filing work rather than selling it in isolation. That's the difference between a certificate broker and an advisor who's managing your whole compliance picture.

We'll tell you plainly what a REC purchase covers for your building, then run the sourcing or structuring ourselves. Read the full breakdown in the Journal →

"RECs, retrofit timing, and the electrification credit are three moving parts of the same plan — we run all three together, not as separate vendors." Why REC sourcing & structuring is a core part of the practice

July 2026. What's passed, and what's still open.

  • May 1, 2026
    Annual LL97 report was due

    For a large wave of co-ops and condos, the first mandatory filing.

  • June 30, 2026
    Grace period & extension window closed

    Buildings could file a BEAM Portal extension for a $60 fee.

  • Aug 29, 2026
    Final deadline for extension holdersOpen now

    If you filed the extension, this is your hard stop. If you never filed at all, your exposure is accruing today.

  • Dec 31, 2026
    Double electrification credit closes

    Qualifying equipment installed before 2027 earns double Beneficial Electrification Credit — applicable against penalties through 2036.

  • 2030
    Caps tighten sharply

    Retrofits take 18–36 months to design and install. 2030 is decided by what you start now.

The credit almost nobody is claiming

The Beneficial Electrification Credit lets you apply a negative emissions coefficient to electricity used by qualifying equipment. Install before 2027 and the coefficient doubles.

For a board weighing whether to replace a dying boiler this year or next, that single date is worth more than most of the advice you'll be given.

Find out what your building actually owes.

Try the free penalty calculator — see what a typical building of your size and type faces, modeled from 12,700+ real NYC buildings.

Then ask for your building's exact numbers: your current emissions, your cap, the projected annual penalty, cumulative exposure through 2030 — and whether you still qualify for the double electrification credit. Written to be forwarded straight to the rest of your board.

Estimates are modeled from City benchmarking disclosure data — built to show the shape and scale of your exposure, not a filed compliance report.

Three services, one point of contact across every reporting cycle.

I.

LL97 Compliance Reports

GHG benchmarking and emissions calculation, prepared for filing and written in language a board can vote on. We handle the submission, not just the math.

What's included →

II.

Retrofit Consultation

Sequencing electrification and envelope work against the incentive calendar — NYSERDA, C-PACE, the electrification credit — so you spend in the right order. We vet contractors and read the quotes with you.

What's included →

III.

REC Sourcing & Structuring

We source certificates directly from the Zone J and NYSERDA Tier 4 market, and structure bespoke REC arrangements when a standard purchase isn't the right fit — run alongside your retrofit and filing work, not separately.

What's included →

Manage more than one building?

We model your whole portfolio against 2026, 2027 and 2030 in one pass and tell you which buildings carry the risk.

The things boards actually ask us.

NYC Accelerator is free. Why would we pay you?

You should use NYC Accelerator — genuinely. What it gives you is education, general guidance, and a referral. What it doesn't do is file on your behalf, sit in your board meeting and answer the treasurer's questions, read a contractor's $400,000 heat pump quote and tell you which line items are padded, source or structure your REC arrangement, or stay accountable to you across four reporting cycles. We do the execution the free program hands back to you.

Can't we just wait? The real limits aren't until 2030.

Two things break that math. First, the penalty is annual and it's running now — five years of $50,000 is $250,000 you could have put into the building. Second, retrofits take 18–36 months to design, approve and install, and the double electrification credit closes at the end of this year. Waiting doesn't defer the cost, it removes your cheapest options.

Board approval can take months. How do you work with that?

That's the normal case, not the exception. We write deliverables to be voted on — a clear recommendation, the cost, the penalty avoided, the funding path, and the documented reasoning that gives you a defensible record if a shareholder challenges the decision later. We'll present to your board directly, and to the shareholders if that's what it takes.

How do we know you won't oversell us?

We run REC sourcing and structuring as one part of a bigger plan — our fee depends on the whole plan working, not on pushing a single certificate purchase the way a broker does. We'll tell you plainly what a REC arrangement covers for your specific building before we run it. We'd rather be the advisor you can check than the one you can't.

We already missed the May 1 filing. Is it too late?

No — this is the most common call we get right now. If you took the BEAM extension you have until August 29. If you filed nothing, you're accruing exposure — but late and correct beats absent. Book a call and bring your address.

Bring us an address.
We'll tell you your exposure.

Thirty minutes, no cost, no engineering jargon. Worst case, you leave knowing your number.
