Existing building commissioning

Program description

Existing Building Commissioning (EBCx) is a comprehensive approach to identifying and implementing the ideal strategy to maximize your building’s performance through the resolution of any operational and maintenance opportunities. The Existing Building Commissioning (EBCx) Program provides you with the expertise and training necessary to maximize the potential within your building through low/no-cost energy efficiency opportunities.

What you get

If you qualify for PSE's EBCx program, you will receive the following:

  • Initial assessment of your site's energy usage and opportunities prior to full program commitment.
  • A comprehensive on-site review of your facility's systems once committed.
  • Recommendations for low/no-cost operational and maintenance (O&M) improvements.
  • Identified capital projects including energy efficiency upgrades.
  • Training to identify, track, and maintain energy savings for (O&M) staff.
  • Comprehensive facility guide documenting how to operate your building efficiently and to maintain realized energy savings.

Building commissioning (Cx) incentives

Assessment Incentive*

After the building assessment has been completed, and the report has been delivered to PSE, you will receive the assessment Incentive using the rates listed for your specific customer type.

PSE all (Electric or Electric/Gas)
Electric Natural gas$5,000

PSE Electric service only (Other Gas)

PSE Gas service only (Other Electric)
Natural gas$2,000

PSE Gas service only (SCL Electric)
Natural gas$1,000

Maximum: Up to 100% of the Cx provider’s assessment costs.

*If the initial assessment finds that your building will not benefit from building Cx or further program participation, you will still be compensated for your assessment fee up to the value above.

Implementation Incentive

Once the Cx process has been implemented with all required training and documentation provided, you will receive the implementation incentive. This incentive is provided for the successful completion of the Cx process and is not tied to how well the building has performed at this point in the process.

PSE all (Electric or Electric/Gas)
Electric Natural gas$0.35/sq. ft.

PSE Electric service only (Other Gas)
Electric$0.25/sq. ft.

PSE Gas service only (Other Electric)
Natural gas$0.15/sq. ft.

PSE Gas service only (SCL Electric)
Natural gas$0.10/sq. ft.

Maximum: Up to 75% of the Cx provider’s fee

First-Year Performance Incentive

Once the building maintains efficient operation one year after receiving the Implementation incentive, earn an additional incentive if you have reached the 6 percent savings target. The incentives can cover 100 percent of the total project cost, including both commissioning and improvement investments.

Electric incentive
PSE Electric service
Electric$0.05/kWh saved

Natural gas incentive
PSE Gas service
Natural gas$0.80/therm saved

Maximum: Up to 100% of combined total of: Remainder of Cx provider's fee, cost of operational improvement(s), and/or energy efficiency upgrade(s).

How you qualify

With the wide variety of energy efficiency programs available to you from PSE, it is important to pick the one most suited for your building and your specific needs. Considering the unique characteristics of all buildings and the benefits of the EBCx we have identified and listed below the most helpful used to identify your building’s potential.

  • Building is at least 75% occupied.
  • Building is managed by automated controls.
  • Energy use is higher than expected and/or trending upwards.
  • Maintenance has been deferred to some extent.
  • Building O&M staff desires efficiency training.

How you apply

Existing Building Commissioning program flow

Preapproval Submit a PSE application along with a building checklist, included in the program document, for PSE to review and approve prior to commissioning.

Assessment — An initial in-person, lite review of your building’s energy using systems is conducted to ensure there are opportunities for improving your building.

Implement — Once your building is flagged during the assessment phase as a candidate for the program, the commissioning process is implemented.

Performance — After the implementation of the cost-effective opportunities, the building energy use is observed for 10-months for the final incentive.

Cx Professionals

All of PSE’s commissioning programs require a minimum level of experience in addition to a high-level understanding of building energy using systems. Successful providers also have strong interpersonal skills, as well as the ability to investigate, implement, and verify energy efficiency opportunities.

PSE maintains an updated list of prequalified Cx professionals that are qualified to participate in all of PSE’s commissioning programs for those wishing to find a qualified professional to commission their facility. If you have a person you wish to use that is not preapproved, you can submit the Cx professional application to receive preapproval.
