This sample scope of work is intended for use by properties seeking to improve building performance through retro-commissioning, also known as existing building commissioning. The scope of work provides a foundation to define retro-commissioning activities and roles and responsibilities at the property. It should be adapted as appropriate to capture client priorities and property-specific conditions. Sample templates to support the scope are also available for download in the box below.
Phase 1 consists of Tasks 1 and 2 and should be priced by prospective retro-commissioning providers at the outset of the project. Phase 2 consists of Tasks 3 and 4 and should be priced following delivery of the preliminary retro-commissioning report so that the specific scope items and implementation activities are aligned.
This scope of work is based on ASHRAE Guideline 0.2 Commissioning Process for Existing Systems and Assemblies and ASHRAE Standard 202 Commissioning Process for Buildings and Systems. The process described herein is intended for general use. While it can help a building meet Building Energy Performance Standards (BEPS) compliance by effectively reducing energy usage and improving ENERGY STAR score, it does not guarantee compliance with the BEPS Prescriptive Pathway retro-commissioning option.
The Hub has created a sample Existing Building Commissioning/Retro-Commissioning scope of work (SOW) to help you define retro-commissioning activities and roles and responsibilities at your property. In addition, we have created ancillary templates for you to download separately and use with your selected provider: sample Current Facilities Requirements (CFR) template and sample Retro-commissioning Plan template.
For most building types, retro-commissioning is either the first or second most cost-effective measure to reduce operational energy use—the energy that is used during the occupancy stage of a building’s life cycle. Read the companion retro-commissioning blog for a quick explainer on the importance of the practice and key steps.
