New York City — Local Law 97

Model Local Law 97 Exposure and Rank Retrofits by ROI

For NYC owners, asset managers and sustainability leads: quantify your building's emissions exposure under Local Law 97, then rank retrofit measures by return — with an audit trail behind every number.

Local Law 97 sets carbon emissions limits for most NYC buildings over 25,000 square feet, administered by the NYC Department of Buildings. The financially rational response is not panic capex — it is modeling your exposure precisely, then sequencing measures by ROI and compliance impact. Refer to the official NYC sustainable buildings resources for current limits and filing requirements.

What the analysis covers

Emissions exposure model

Building emissions calculated from utility data and mapped against LL97 limits for your occupancy classes.

EUI baseline

Energy Use Intensity baseline and benchmark, consistent with your benchmarking submissions.

Measure ranking

Electrification, envelope, controls and plant measures ranked by capex, payback and emissions impact.

Capex & payback sequencing

A sequenced capital plan showing which compliance periods each package addresses.

NOI impact framing

How energy cost reduction and avoided penalties flow into net operating income, stated with assumptions visible.

Audit trail

Every figure carries provenance — inputs, method and standard — ready for scrutiny.

What you upload

  • Utility bills or benchmarking data (12–24 months ideal)
  • Basic building details — gross floor area, occupancy classes
  • Any energy audit, retro-commissioning or BMS evidence held

What you receive

  • LL97 emissions exposure model by compliance period
  • EUI baseline and benchmark position
  • Ranked retrofit plan with indicative capex and payback
  • Board-ready evidence pack with a full audit trail

Turnaround is rapid and depends on the completeness of the data you share.

Every figure in an Intelli-BuildAI report links back to its input evidence and the standard it was calculated against. Review a sample before you share any data.

Transparent methodology

Outputs are produced by deterministic, physics-based calculation engines referenced to published standards, with data provenance recorded per input. Where inputs are incomplete, results are clearly marked indicative pending validation — no figure is presented as verified until the underlying evidence supports it.

Frequently asked questions

Does this tell me my exact LL97 penalty?

It models your emissions against published LL97 limits so you can see indicative exposure by compliance period. Specific penalty amounts and filing requirements are governed by the NYC Department of Buildings — we link the official sources rather than restating them.

We already benchmark under LL84 — what does this add?

Benchmarking reports consumption. This converts that data into an exposure model and a ranked, costed retrofit sequence — the decision layer benchmarking does not provide.

Can it evaluate electrification measures?

Yes. Heat pump conversions, plant replacement, controls and envelope measures are modeled with physics-based calculations, including their emissions-coefficient implications.

Is the output usable with lenders and boards?

Yes — every figure links to its inputs and method, which is the format boards, lenders and consultants can interrogate rather than accept on faith.
