Local Law 84
May 1 benchmarking, without the all-nighter.
Local Law 84 requires NYC buildings over 25,000 sq ft to benchmark energy and water consumption every year through EPA's Portfolio Manager. The deadline is May 1. The penalty for missing it is $500 per quarter — stacking until you file. LLDesk tracks the deadline, audits your submission for the most common rejection reasons, and funnels the data straight into your LL97 model.

Common rejection reasons
Four reasons your benchmarking gets bounced.
Most LL84 rejections aren't exotic. They're the same four issues, year after year. We surface them before you submit.
Missing 12 months of utility data.
Portfolio Manager rejects submissions where any meter has fewer than 12 consecutive months of consumption. Vacancy, sub-meter changes, and utility account transfers are the usual culprits. LLDesk flags meter gaps before submission, not after.
Wrong gross floor area.
Benchmarking GFA must match what's been certified. PLUTO and DOF records often disagree, and a 5% mismatch is enough to bounce the filing. We pull both and surface the discrepancy.
Mis-mapped property use.
Multifamily-housing vs. residential-care vs. mixed-use changes the energy-use intensity calc and downstream LL97 exposure. A miscategorized use type quietly poisons every report after it.
Unreported parking or common-area meters.
Garage, lobby, and common-area electric is part of whole-building consumption under LL84. Owners forget. The DOB does not.
What LLDesk does for LL84
Benchmarking, with a real workflow.
May 1 deadline tracking.
Every benchmarking-eligible BIN you add to LLDesk shows up in your dashboard with a May 1 due-by countdown. Reminders fire 60, 30, 7, and 1 day out so the deadline never sneaks up.
Portfolio Manager handoff, simplified.
We track which buildings have an EPA Portfolio Manager Property ID linked, when their data sharing was last refreshed, and whether the city's compliance report shows green. Less Excel, more confidence.
Penalty math, not vibes.
LL84 violations stack at $500 per quarter — and the city happily issues four in a single year for one missed filing. LLDesk shows you the running exposure as the deadline approaches.
Feeds straight into LL97.
Your benchmarking data becomes the input for LL97 emissions modeling. Clean LL84 = honest LL97 numbers. Sloppy LL84 = a Period 2 surprise you didn't budget for.
