Energy audits for Manhattan office towers, co-ops and institutions.
From pre-war office buildings on district steam to post-war co-ops and glass towers, we audit Manhattan buildings for LL87 compliance, LL97 planning and lower operating costs.

What we see in Manhattan buildings.
Manhattan has the densest concentration of large buildings covered by Local Laws 87 and 97. Many older office and residential buildings are heated by Con Edison district steam, which has its own emissions coefficient under LL97 and its own set of efficiency measures, from steam trap programs to pressure reducing station tune-ups.
Common findings in our Manhattan audits include overheating in steam-heated buildings, outdated BAS sequences in office towers, constant-volume air handlers that could run on variable speed, and lighting systems that predate LL88. Multi-tenant buildings benefit most from sub-metering and tenant engagement.
Rules that apply in Manhattan
Most Manhattan buildings over 25,000 sq ft fall under LL84 benchmarking and LL97 emissions limits; those over 50,000 sq ft also file LL87 audits.

FAQ
Manhattan energy audits.
Do you audit steam-heated buildings?
Yes. Steam distribution, traps, vents and controls are a core part of our Manhattan audits, along with the LL97 implications of district steam.
Can one audit cover LL87 and LL97?
Yes. An ASHRAE Level II audit with retro-commissioning satisfies LL87 and provides the measures and data needed for an LL97 compliance plan.
