Retro-Commissioning

Retro-Commissioning

Every ten years, affected building owners must perform retrocommissioning, a process that improves the efficiency of existing building operations by “tuning up” and calibrating existing functional systems to run as efficiently as possible through low- or no-cost improvements.

Owners must implement the cost-effective measures (any measure with a payback period of two years or less with rebates) identified through retrocommissioning within two years of the study.

The scope of the requirements depends on the size of the building as shown below.

Building Size RCx Scope
Buildings < 50,000 SF Owners can participate in the   Xcel Energy Building Tune-Up Program   or meet the scope docx outlined in the City Manager Rules
Buildings ≥ 50,000 SF Owners can participate in the   Xcel Energy RCx Study Program   or meet the scope docx outlined in the City Manager Rules
  • Building owners must use a   Qualified Service Provider   to complete the retrocommissioning study.
  • Review the RCx Checklist pdf to prepare for compliance.
  • Submit the final RCx report and a copy of the Xcel Recommissioning/Building Tune-up Rebate Application through the online Submission Form.
  • Submit proof of measure installation through the online submission form Coming Soon.

Report Templates

If completing the RCx study through Xcel Energy's Building Tune-up or RCx Study Programs, the program report AND a copy of the Xcel Recommissioning/Building Tune-up Rebate Application will suffice for compliance.

If completing the RCx study through a third-party service provider, a report outline docx is available for reference. 

Cost-Saving Opportunities

Retrocommissioning Study

Cost saving opportunities may be available through participation in Xcel Energy's programs. 

There may also be opportunities to realize cost savings through implementing services concurrently (e.g. completing the energy assessment and retrocommissioning study at the same time). Work with your service provider to determine if there are opportunities to capture economies of scale.

Measure Implementation

Prescriptive and custom rebates may be available through  Xcel Energy and  Boulder County PACE to reduce the costs of measure upgrades.
