Commercial energy audits · NY & NJ
We audit commercial, multifamily, industrial and public buildings following ASHRAE Standard 211. Each audit gives you a clear picture of where energy is used and a costed plan to cut it.
Audit levels
Each ASHRAE level builds on the one before it. A Level I screens a building in days. A Level III gives a lender or ESCO numbers they can finance against.
A screening audit that benchmarks your building and identifies no-cost and low-cost opportunities.
Our most requested audit. Every major system is surveyed and each measure gets a savings and cost estimate.
Detailed engineering for capital-intensive measures, built to support financing and performance contracts.
| Level I | Level II | Level III | |
|---|---|---|---|
| Utility bill analysis | ✓ | ✓ | ✓ |
| EUI benchmarking | ✓ | ✓ | ✓ |
| Site survey | Visual walk-through | Every major system | Every system, with data loggers |
| Thermal imaging | Optional | ✓ | ✓ |
| End-use breakdown | Estimated | Calculated | Metered & modeled |
| Savings accuracy | Order of magnitude | ±20–30% | ±10–15% |
| Cost estimates | Rough | Engineering estimate | Contractor quotes |
| Energy modeling | — | Where needed | Calibrated model |
| Meets LL87 | No | Yes, with RCx | Yes, with RCx |
| Supports financing | No | Partially | Yes |
Site energy by end use. Your audit replaces these with your building's numbers.

Analysis
An end-use breakdown is the backbone of a good audit. It shows which systems deserve your capital and stops you spending on measures that look good but save little.
What we examine
Our engineers inspect the building from the roof to the boiler room. These are the systems covered in a Level II audit.
Insulation, windows, air leakage, roof and slab-edge heat loss with infrared imaging.
Steam and hot-water boilers, burners, combustion efficiency, steam traps, distribution.
Chillers, cooling towers, rooftop units, split systems and heat pumps.
AHUs, fans, outdoor air rates, economizers, exhaust and energy recovery.
Schedules, setpoints, sequences of operation, sensor calibration and trend review.
Fixture inventory, LED retrofit options, occupancy and daylight controls.
Water heaters, recirculation, low-flow fixtures, heat pump water heaters.
Motor efficiency, variable frequency drives, pump and fan sizing.
Leak surveys, compressor controls, process heat and industrial loads.
Server rooms, kitchen equipment, vending and after-hours loads.
Demand charges, rate class, supply contracts and billing errors.
Solar PV feasibility, heat pump conversion and electrification readiness.
Process
A Level II audit for a 100,000 sq ft building takes about six weeks from kickoff to presentation.
Deliverables
The report opens with a two-page executive summary for decision makers. The technical sections give your facility team and contractors everything they need to implement.

An ASHRAE energy audit follows ANSI/ASHRAE/ACCA Standard 211, which defines three levels of commercial building energy audits. Level I is a walk-through screening, Level II is a detailed energy survey and analysis, and Level III is an investment-grade audit with detailed engineering for capital projects.
Local Law 87 requires an energy audit that meets ASHRAE Level II, plus retro-commissioning of base building systems. Both are filed together as an Energy Efficiency Report with the NYC Department of Buildings.
A Level I audit typically takes two to three weeks from data collection to report. A Level II audit for a mid-size building usually takes four to eight weeks. A Level III audit with data logging and energy modeling can take two to four months.
At least 12 months, ideally 24 to 36 months, of utility bills for every fuel, building drawings if available, equipment lists, BAS access or trend data, and a contact who can walk our engineers through the mechanical spaces.
Cost depends on building size, complexity and audit level. We quote a fixed fee after reviewing your building details and utility data. Many New York and New Jersey utility programs cover part of the audit cost.
Yes. Our Level II and Level III reports include the savings calculations and documentation that Con Edison, NYSERDA, PSE&G and NJ Clean Energy programs ask for, and we can prepare the applications.
