Building automation systems (BAS) can trend important variables associated with the operation of the building systems. This type of trending can support ongoing commissioning efforts but will not be adequate as a stand-alone strategy to satisfy the intent and rigor of the ongoing commissioning activities required for this credit. 

Track energy conservation measures over time to determine the actual payback, and compare to the initial projections.

If you implement the commissioning plan in-house, you may still want to work with a third-party firm to develop the plan. This is a good way of reducing costs while getting the benefit of outside expertise.

Consider additional training for building engineers to bring more of the ongoing commissioning work in-house. This will reduce costs, and also contribute to the training requirement as part of EAc2.2. 

The ongoing commissioning process requires repeated systems testing and evaluation over a two-year cycle. This process requires an increased level of expertise and experience, is generally contracted through a third party, and can be costly.

Make a list of all building equipment relevant to the commissioning process. Note how frequently each item should be tested and include procedures for responding to deviations from the expected performance parameters.

Establish procedures for responding to deviations from the expected or preferred performance parameters.

Establish the planning, system testing, and performance verification tasks required to complete the commissioning cycle.

Develop an ongoing commissioning program. This program should include a detailed schedule and budget broken out by phase for the completion of the overall commissioning cycle, and should emphasize integration of the commissioning activities into the building’s standard procedures. The ongoing commissioning process cannot exceed 24 months in duration.
