Benchmarking, audit and retro-commissioning, and emissions compliance are different assignments—but they work better when their data and capital decisions stay connected.
Local Law 84: keep the annual data record clean
Benchmarking organizes annual energy and water information in ENERGY STAR Portfolio Manager and supports the applicable city submission. The work depends on complete accounts, accurate meter relationships, correct property-use details, and a review of gaps, estimates, or unusual values.
A credible benchmarking record has value beyond the filing. It gives ownership a consistent baseline for year-over-year comparison, portfolio triage, audits, emissions planning, and verification of completed improvements.
Local Law 87: investigate the building and its operation
Local Law 87 work generally combines an energy audit with retro-commissioning for applicable buildings and cycles. The assignment looks beyond annual totals to building systems, controls, operation, maintenance, observed deficiencies, and potential energy conservation measures.
The most useful result distinguishes operational corrections, maintenance needs, and capital projects. It also states the documentation and corrective-action path clearly enough for the owner, property team, and required professionals to carry it through.
Local Law 97: manage emissions as a building strategy
Local Law 97 brings building data, emissions limits, filing requirements, operations, equipment, capital plans, and available compliance pathways into one recurring ownership decision. A building-specific analysis matters because utility mix, use, systems, occupancy, constraints, and planned work differ even among similar properties.
The plan should connect current compliance work with realistic reduction measures and timing. Operational changes, controls, maintenance, equipment replacement, envelope work, electrification, and other measures may each play a role, but they have to be evaluated as part of the actual asset plan.
Use one source of truth across the three
Ownership benefits when the annual utility record, equipment inventory, audit findings, retro-commissioning corrections, emissions calculations, and capital projects are maintained as connected information. That reduces duplicate collection and makes it easier to see when one compliance task changes another.
Applicability, cycles, filing instructions, definitions, and other requirements can change. Each engagement should confirm the current requirements with authoritative sources and the appropriate legal and technical professionals for the property.
