If a building is less than 10 years old, is it automatically exempt from both the energy audit and the retro-commissioning?

For new buildings (NBs) with a First Temporary Certificate of Occupancy that is less than ten years old at the time the building is due to comply with Local Law 87/09, owners do not need to submit an EER or a Request for Deferral.

For existing buildings that are undergoing Type 1 Alterations (Alt-1), owners must submit a Request for Deferral and proof of compliance with the NYC Energy Code (NYCECC) that was in effect at the time of application approval of the alteration. Proof of compliance must include all lesser and included permits affecting base building systems. EER1 form (Application to Defer Filing) must be submitted with substantial documentation such as completed EN1 Energy Cost Budget Worksheet, EN sheets from the plans, and input/output results of ComCheck or energy modeling, as applicable.

For buildings that are undergoing Type 2 (Alt-2) and Type 3 (Alt-3) alterations, which are causing difficulty with compliance during the year in which they are due, owners should submit an extension request. Extension requests are due by October 1st. The due date for the property would then be extended by one year. Up to two extensions may be granted.

Is it acceptable to continue using the previous Excel based Energy Audit Data Collection Tool?

For reporting year 2018, use of the newer web-based U.S. Department of Energy’s Asset Score Audit Template  was optional. The Department continued to accept the previous Excel-based Energy Audit Data Collection Tool for reporting year 2018.

Beginning with reporting year 2019, use of the newer web-based U.S. Department of Energy’s Asset Score Audit Template is required and the Department is no longer accepting the previous Excel-based Energy Audit Data Collection Tool.

The Retro-commissioning Data Collection Tool continues to be Excel-based until otherwise notified.

How are the Current Facility Requirements (CFR) established for a facility undergoing retro-commissioning?

It shall be the responsibility of the retro-commissioning agent to develop, document, and define the Current Facility Requirements (CFR) for the facility. The Retro-commissioning agent must consider the following to develop, document, and define the CFR:

  • Age of the facility
  • Interviews conducted with owners, facility manager(s), maintenance staff and occupants
  • Available design or as-built drawings
  • Lease terms with regard to energy usage
  • Changes in occupancy and space use

The CFR document should include acceptable seasonal operational setpoints, adequate operating (occupied and non-occupied) schedules, satisfied load conditions under which the equipment operates, indoor environmental quality requirements and the desired equipment efficiencies of the base building systems and sub-systems.

The established CFR should be substantiated by references that may include: ASHRAE fundamentals, heating, ventilation, and air conditioning (HVAC) systems and equipment, and applications handbooks, ANSI references, Illuminating Engineering Society (IES) lighting handbooks, New York City Housing Maintenance Code (HMC), New York City Building Code (BC) and/or manufacturer’s guidelines. The CFR cannot be based on the needs of operation that may have resulted due to deficiently-performing equipment or historic operations.
