BPS Radar · for NYC MEP engineers and LL97 consultants

Find the buildings that need an engineer before they ask for bids.

Every month: the NYC buildings over their 2030 emissions limit where no engineer has filed heating or energy work, with the managing agent or owner where the city's records show one, and a dated reason to get in touch.

Why it exists

Three things that slow down LL97 business development

You can't tell which buildings already have an engineer.

White spaceBuildings with $50k to $1M a year of projected exposure and no heating or energy work filed with the city in the last 3 years.

Owners are waiting until 2029.

Why nowLL87 energy audit years, plus new deeds, mortgages and engineer filings in each monthly update, so you know which owners are about to make decisions.

It's hard to tell who actually decides.

Who to reachThe managing agent or owning company with a mailing address, and how many other over-limit buildings they run.

What's in every row

One row per building, ready to work from

Excel and CSV, sorted by projected exposure. Each column says where it comes from.

Projected 2030 exposureYearly figure from 2030 if energy use stays as last reported, plus the 2030–34 total.
Cut neededHow far emissions must fall to meet the 2030 limit.
Gas and oil shareHow much of the problem is on-site combustion, which points to heating work.
Filing statusWhether any heating or energy work was filed with the city in the last 3 years.
Managing agent or ownerCompany name and mailing address from city property and building records.
PortfolioOther over-limit buildings with the same managing agent or owner.
Why nowLL87 audit year, and from the first monthly update, recent deeds, mortgages and new filings.

The data

Official sources, the law's own method, checked against the city

Every number on the list can be traced to a public city record and checked by you.

Sources

Official city records

Building energy reports, building filings and property records published by the City of New York. The list is rebuilt every month as new records come out. Nothing scraped, nothing bought from data brokers.

Method

Calculated the way the law sets out

Each building's exposure follows the Local Law 97 rules: its emissions, its legal limit and the penalty set in the law. Every limit was checked against the rule itself.

Accuracy

Checked against the city

14 of 14

In a 28-building spot check, all 14 like-for-like buildings came within 10% of the city's own LL97 directory. Rows where the city is likely to show a different figure carry a note saying why.

Questions

Frequently asked

The data

Where does the data come from?

Official records published by the City of New York: annual building energy reports, the city's list of buildings covered by Local Law 97, building job filings and permits, and property and registration records. Nothing is scraped and nothing is bought from data brokers.

How accurate is it?

Every property-type limit was checked against the LL97 rule itself, and in a 28-building spot check against the city's own LL97 directory, all 14 like-for-like buildings came within 10%. Rows where the city's directory is likely to show a different figure, for example because it uses an older report, carry a note saying why.

How fresh is it?

The list is rebuilt every month from the latest city releases. Energy figures come from each building's most recent annual energy report, and every row shows which year that is.

Is the figure a fine?

No. It's a projection of gross exposure from 2030 if the building's energy use stays as last reported. It ignores renewable energy credits, deductions and adjustments, and 2030 emissions won't be reported until 2031.

Does "no filing" mean the building has no engineer?

Not necessarily. Most covered buildings have a registered design professional who signs the annual LL97 report, and design work can start before anything is filed. It means no heating or energy work has been filed with the city in the last 3 years.

The list

Which buildings are on it?

Privately owned buildings covered by Local Law 97 that are over their 2030 limit, with $50k to $1M a year of projected exposure. Hospitals, universities, city-run buildings and the largest towers are left out, so the list suits small and mid-sized firms.

How is this different from the city's free directory?

The city's directory shows one building at a time, once you know which building to look up. This list tells you which buildings to look at: the ones over their 2030 limit where nobody has filed heating or energy work, with who manages them and what changes each month.

How is it different from PropertyShark or Reonomy?

Those show owners, sales and phone numbers for any property. They don't show which buildings are over their LL97 limit, by how much, or whether anyone has filed heating or energy work there. You may want one alongside this list to find a phone number.

Where do the contacts come from?

Public city filings about who owns and manages each building. Contacts are company-level, with a mailing address. Some records also name a person in a business role, as they appear in the city filing. No email addresses or phone numbers. Anyone listed can ask to be removed. See the privacy notice.

Which boroughs can I get?

Manhattan, Brooklyn, the Bronx and Queens. Staten Island isn't offered: too few buildings qualify for a useful list.

Working together

How does the pilot work?

$500 for one borough. You get the full list within 3 business days as Excel and CSV, then 3 monthly updates showing sales, refinancings and new engineer filings at over-limit buildings, and buildings that joined or left the list. Invoice by Stripe, in USD.

What if the contacts aren't good enough?

If fewer than 65% of the buildings delivered come with a company name and mailing address, you get a full refund.

Can I share the list inside my firm?

Yes. Anyone at your firm can use it for your own business development. Please don't resell it or pass it to other firms.

Do you do engineering or compliance work?

No. Rohdea only supplies data. It doesn't offer engineering, compliance or retrofit services, so it never competes with you for the work.

Who is behind this?

BPS Radar is made by Rohdea Limited, a data company registered in England and Wales (company no. 17254728). It's run by Nelson Fung, a data engineer who works with public records. Calls are on US Eastern time. Rohdea is on LinkedIn.
