Identify the applicable building and filing year
A business owning a covered New York City building can face an energy audit and retro-commissioning obligation that is distinct from annual benchmarking or an emissions report. Local Law 87 addresses identifying energy-saving measures and confirming how existing building energy systems operate. An annual utility-data submission should not be assumed to complete that different project.
The Department of Buildings describes coverage using building and tax-lot size records, including specified multiple-building and condominium arrangements. It links a current 2026 covered-building list and warns that the 2025 list may be outdated. Review the actual property identifiers and records before using an old acquisition spreadsheet as the coverage determination.
The ordinary ten-year assignment follows the last digit of the tax-block number and the filing year. Obtain a supported calendar for the property, including prior submissions and any approved relief. A change of owner or the installation of one efficient piece of equipment does not, by itself, establish that the building’s next Energy Efficiency Report is no longer due.
Separate the audit from the system correction work
The city describes an energy audit as analysis of building energy use to identify opportunities. Retro-commissioning concerns whether existing systems are installed, tested, operated, and maintained according to the applicable operational needs and design intentions. Ask the professional to define both scopes and the supporting records required for the report.
Provide equipment inventories, controls sequences, drawings, maintenance histories, utility information, occupancy schedules, and prior work. A theoretical savings calculation may not show whether a sensor works, a control setting matches actual occupancy, or a system has been functionally tested. The owner needs a dated project plan identifying investigation, required measures, documentation, and filing.
Coordinate access and testing with the operating business. Some observations may require equipment to run under relevant conditions, and corrective work can affect employees or production. Do not leave all fieldwork to the final filing week and assume the report can be completed from invoices. Have the responsible professional identify the actual lead time and any missing information early.
Compare costs and savings using the completed scope
Consider a hypothetical professional proposal of $12,000 for audit and report work, $8,000 for retro-commissioning investigation and testing, and $15,000 of separately identified measures. The modeled project cost is $35,000 before other work, fees, or operating disruption. If only the $12,000 report quote appears in the reserve, the budget omits $23,000 of the proposed scope.
Assume the supported forecast attributes $7,000 of annual energy-cost savings to the completed measures. A simple $35,000 divided by $7,000 calculation produces five years, before financing, maintenance, price changes, taxes, and time value. This is a sensitivity, not a guaranteed payback or a conclusion that every measure is required. Ask the professional to identify which estimates depend on actual operating changes.
Distinguish the compliance project from optional capital replacements evaluated through the audit. A report identifying a future boiler or controls opportunity does not independently establish that every replacement must be made immediately. Conversely, a decision to postpone an optional project should not be assumed to excuse required retro-commissioning measures or the actual report submission.
Use the correct deadline and retain submission evidence
The city’s February 2026 notice specifies a December 31, 2026 EER deadline for buildings required to comply in 2026. It expressly states that 2025 extensions do not apply to the 2026 filing year. A separate notice extended the 2025 filing-year deadline to March 31, 2026. Keep the obligation year distinct from the calendar date when a prior-year filing was accepted.
Review any extension, deferral, exception, or disputed coverage with the appropriate professional using current requirements. The city describes particular conditions and application procedures; an owner should not infer relief merely because a building recently underwent some renovation. Retain the actual approval or supported determination and the resulting calendar.
Keep coverage records, prior reports, professional scope, audit information, testing and measure documentation, current reporting tools, submission confirmation, and unresolved items together. This guide does not determine a building’s coverage or certify compliance. Its practical premises decision is to plan the audit, retro-commissioning, and EER as their own completed project, so a business’s energy reserve and filing calendar reflect the actual work rather than a different annual reporting task.
