Abstract
BamCore, LLC has submitted an application and supporting documentation requesting approval of an exceptional method compliance option for its Prime Wall system, referred to generically throughout this document as a dual-panel hollow (DPH) wall system. The unique DPH wall system consists of interior and exterior wood panels that are installed with minimal blocking before the installation of insulation. The application is consistent with the compliance option procedures in Section 10-109 of the Building Energy Efficiency Standards.
California Energy Commission (CEC) staff believes the intent of the application is warranted, and the content of the BamCore proposed changes to the compliance software and documentation is appropriate.
Staff has solicited stakeholder comments and received several public comments during the review period. All comments received supported the DPH system, so no public workshop was held.
This final staff report represents CEC staff’s review and recommendation for approval and finalization of the compliance tools and documentation needed to implement the dual-panel hollow wall exceptional method compliance option.
