The following are updates and reminders regarding the 2019 RBES and CBES update process. All of the links below can be found on the Department of Public Service’s Building Energy Standards Update Page.
First, revised versions of the proposed 2019 RBES have been posted on the PSD website at the following links:
This revised document reflects changes to the stretch provisions in Section R407. Upon posting the original redlined document on September 22, the code update team completed additional modeling and identified that the stretch code posted on September 22 did not achieve the target improvement over the 2019 base code nor did it match the approach discussed during the stakeholder meetings. The revised stretch code document for your review, dated October 2, is the correct stretch code to review prior to the Stakeholder meeting on October 11. It outlines modified stretch packages and reduced points requirements compared to the first posted version. Note that the only significant changes were to Section R407. All other changes were for accuracy, clarity and consistency.
Second, revised versions of the proposed 2019 CBES have been posted on the PSD website at the following links:
The update to this document reflects changes to HVAC control serving guestrooms in hotels/motels and the exterior piping insulation, which were discussed in Stakeholder and Advisory Committee meetings but were inadvertently excluded from the redline circulated. Note that the only significant changes were to Sections C403.8.4 and C403.7.6
If you have already reviewed the versions of the proposed 2019 RBES and CBES that were posted on September 22, please replace them with the versions at the links above.
Additionally, the proposed 2019 CBES Stretch guidelines are available [here].
Interested parties are encouraged to review and comment on these guidelines, which will potentially be used for commercial projects that require an Act 250 permit.
