Hospitality-EBOM-v4 EAc2: Existing building commissioning - implementation

  • Implement the results of your energy analysis

    Now that you’ve identified energy efficiency measures in the ASHRAE Level II audit or retro-commissioningThe process of verifying and documenting that a building and all of its systems and assemblies are planned, designed, installed, tested, operated, and maintained to meet the owner's project requirements. analysis from EAc1, it’s time to cash in with the implementation credit.

    The credit is really a no-brainer if your project is pursuing EAc1, as the cost outlay is typically small and the long-term returns on those expenditures tend to be very strong.

    To earn the credit you first need to establish criteria for determining “low-cost” measures. The cost threshold for “low-cost” is set at your team’s discretion. Then you’ll need to ensure that all low-cost and no-cost measures can be completed prior to the end of the performance period.

    And finally, make plans to ensure that the benefits of the implemented efficiency measures are fully realized by providing training for the building operations staff and by developing a tracking and verification program. The tracking program in particular should verify the effectiveness of key changes and/or installations, document the actual cost savings observed, and document the human benefits of the implemented measures.

    What’s New in LEED v4

    • The capital plan required for major retrofits and upgrades is now specified as a five-year plan.
    • A formal tracking and verification plan is now required for the implemented energy conservation measures.

    FAQs

    What constitutes a “low-cost” measure?

    There is no prescriptive guidance for establishing the threshold for a low-cost measure. It’s up to your team to decide based on the available budgets and constraints of the building operations. 

    What does the training for building personnel need to cover?

    The LEED Reference Guide outlines suggested topics for this training but it should generally cover how to operate and maintain new equipment, controls, and systems appropriately.

    Requirements

    Establishment

    Meet the requirements of EA Credit Existing Building Commissioning—Analysis.

    Performance

    Apply the requirements below to all direct energy-consuming or energy-producing systems, including lighting, process loads, HVAC&R, domestic water heating, and renewable energy.

    Implement no- or low-cost operational improvements and develop a five-year plan for equipment replacement and major modifications or upgrades based on the analysis phase.

    Confirm training of building operations staff so that they can efficiently operate all new or substantially altered building equipment or systems.

    Develop a formal tracking and verification program for all projects implemented as part of the existing building commissioning process. Include verification of effectiveness, documentation of the observed financial costs and benefits, and observed or estimated environmental and human health and comfort benefits.

    Update the operations and maintenance plan and the current facilities requirementsThe implementation of the owner's project requirements, developed to confirm the owner's current operational needs and requirements. to incorporate the newly implemented improvements.
