Measures can obtain approval for Proven status if the section 3.2.3 UES quality criteria for Proven measures are satisfied. Sunset criteria will be assigned by the RTF along with a plan for data collection and analysis that allows the UES estimate to be reviewed and updated in a timely fashion.

If the sunset criteria are met, and the new or revised UES estimates have not been approved, the RTF will deactivate the measure. This means that the UES estimates are no longer approved by the RTF. The RTF may decide to deactivate a measure before the sunset criteria is satisfied based on unanticipated factors, such as the adoption of new energy codes or the release of study results with findings that invalidate the UES values or the procedures for estimating those values.
