High Performance Building Envelope (HPBE) CXS

The High Performance Building Envelope Center of Expertise in Sustainability (HPBE-CXS) serves to enhance the knowledge base of the science, theory and application of air barriers and enhanced building envelopes throughout USACE. The HPBE-CXS is available to support stakeholders through all phases of design and construction of building envelopes and air barriers and to help remediate envelope and air barrier failures. The team is actively engaged in providing training USACE-wide through webinars and Proponent-Sponsored Engineer Corps Training (PROSPECT) classes and is available to help resolve air barrier and building envelope design and installation issues as they arise.
