What approach should commissioning take regarding project costs and ROI?

• A. Ignore ROI and focus only on function.
• B. ROI is not relevant.
• C. Track Cx-specific costs, compare to anticipated savings from improved performance, and document ROI.
• D. Only track costs but not savings.

Answer: (C)

Measuring value means linking performance improvements to the project’s financial outcomes. The best approach is to track commissioning-specific costs, compare them to the anticipated savings from improved performance, and document the ROI. This means accounting for all activities tied to the commissioning process—design reviews, functional testing, systems optimization, training, and post-occupancy support—and then estimating the resulting benefits such as lower energy use, reduced peak demand, fewer operating issues, and potentially improved occupant productivity or comfort. By documenting ROI, you provide a clear picture of the payback and overall value the commissioning delivers, which helps owners justify the investment and informs future decision-making.

Simply ignoring ROI or treating it as irrelevant misses the economic justification for commissioning. Tracking only costs without showing savings doesn’t demonstrate value, and tracking only savings without costs leaves the investment side unknown.
