LL84, LL87, LL88:
The Energy Compliance
Bundle

LL84, LL87, and LL88 are the three components of NYC's Greener, Greater Buildings Plan from 2009. Together they require energy benchmarking, periodic audits, and lighting and sub-metering upgrades. Fifteen years on, benchmarking scores exist, reports sit on shelves, and citywide energy intensity has barely moved. The laws still cost boards hundreds of millions a year.

The mandate.

LL84/2009 (benchmarking): Every "covered" building (originally >50,000 sf, expanded in 2016 to >25,000 sf) must benchmark energy and water use annually using EPA's Portfolio Manager. Scores post publicly. Penalty: $500/quarter for non-filing.

LL87/2009 (audits & retro-commissioning): Every covered building must undergo an ASHRAE Level II energy audit and retro-commissioning every 10 years, performed by a certified Energy Auditor and Retro-Commissioning Agent. Filed as the Energy Efficiency Report (EER).

LL88/2009 (lighting & sub-metering): Lighting in non-residential spaces must meet current code. Tenant commercial spaces over 10,000 sf must be sub-metered with monthly tenant statements. Deadline fully effective 2025.

Statutory cite: NYC Admin. Code §§28-309 (LL84), 28-308 (LL87), 28-310 (LL88).

What it actually costs.

Who extracts the money.

• Benchmarking consultants (35% of LL84 spend): Pull utility data, enter into Portfolio Manager, submit. The task takes 2-4 hours per building but is billed $1,500-$4,000.
• Certified Energy Auditors (60% of LL87 spend): ASHRAE-certified professionals. Fees $25-$80K per building, regardless of building complexity.
• Retro-Commissioning Agents (30% of LL87 spend): A separate certification. Same firm often staffs both roles.
• Lighting contractors (LL88): LED retrofit crews — margins 20-35%.
• Sub-meter vendors (LL88): Equipment + installation. Vendors specified by MEP engineers who collect reps' commissions.
• Expediters: $500-$2,500 per filing to navigate DOB NOW submission portals.
• DOB penalties: $500/quarter for late LL84, up to $3,000 per annual violation for LL87, $500/quarter for LL88 non-compliance.

The safety benefit — real or theater?

These are not safety laws. They are information-and-improvement laws. The theory: public benchmarking creates peer pressure; audits reveal efficiency opportunities; lighting and metering drive behavior change.

In practice, fifteen years of benchmarking data shows citywide residential energy intensity has declined roughly 8% since 2010 — slower than the national average and slower than buildings that did no NYC-specific compliance at all. LL87 audit reports are, in most cases, produced, filed, and shelved. Urban Green Council's own review found weak correlation between audit findings and subsequent implementation. LL88 lighting upgrades are a genuine payback project (2-5 year ROI), but most buildings would have done them anyway as ballasts failed.

In our view, LL84 benchmarking is cheap and useful. LL87 is mostly compliance theater — $150-$400 million a year for reports that rarely drive action. LL88 is a mixed bag.

Conflicts of interest no one talks about.

• The auditor is often the designer. The same firm performing the LL87 audit is frequently retained to design LL97-driven retrofits. They have an incentive to identify many opportunities.
• No competitive bid norm. Managing agents rotate three or four preferred auditors across their portfolio. Boards rarely see a true competitive bid.
• Cert bodies as paid gatekeepers. ASHRAE and AEE certifications gate market entry. Fees, CEUs, and renewals create a closed labor market.
• Sub-meter vendor lock-in (LL88). Proprietary reading systems bind the building to the original vendor for ongoing monthly reports.

How to check your building's status.

• NYC Open Data LL84 file: Search "Energy and Water Data Disclosure" — enter BBL to see your building's annual benchmarks.
• DOB BIS and DOB NOW > Sustainability: Look for EER (LL87) filing status.
• Ask your managing agent for the most recent Energy Efficiency Report. You are entitled to see it.
• Red flag: building has paid LL87 audit fees in the last 10 years but the report is "in draft" or unavailable.

What to do before you buy.

• Pull the building's LL84 Energy Star score; below 50 is below-median performance
• Ask for the LL87 EER and its implementation log
• Ask whether LL88 lighting + sub-metering was completed by the 2025 deadline
• If the building is commercial-heavy, ask about sub-meter vendor contracts and monthly statement fees
• Cross-reference LL87 findings against upcoming LL97 retrofit plans — they should align

The bottom line.

The 2009 energy laws were a sensible first step in a world before LL97. With LL97 now in effect, the LL87 audit in particular is largely redundant — it is a separate consulting engagement producing a document the LL97 pathway study will mostly ignore. In our view, LL87 should be repealed and folded into LL97 reporting.

LL84 should be automated through a direct utility-API to DOB — no consultant required. LL88 lighting is fine. LL88 sub-metering should be opened to any NIST-certified device so buildings are not vendor-locked.
