Energy News & Tech Tips. Project of the Quarter
Tech Tip: Site-Built Fenestration Fenestration is an industry term referring to any glass door or window. Site-built fenestration refers to any product where the glass and frame are manufactured separately, and assembled on the job site. Typical examples of site-built fenestration are floor-toceiling glass assemblies, large lobby or conference room view windows.

Events & Trainings The CMFNH team would like to invite you to our Multi-Family Residential New Construction Training series. For descriptions and registration information, please visit our training page or contact Ashley Beals at 916-962-7001 or beals@hm-g.com.
The majority of site-built fenestration is installed in high-rise residential (multi-family, four stories and more) and commercial buildings. In order to meet Title 24 requirements for a building permit, the contractor must submit the performance specifications of the fenestration product. Site-built fenestration presents a challenge because the final assembly cannot be certified in a controlled environment. The energy consultant must document the performance specifics of all glazing assemblies (U-value, SHGC, and VT) to meet performance approach requirements. These characteristics can be determined by consulting the CEC default values (Table 116-A, 116-B and Reference Appendix NA-6) or by utilizing the Component Modeling Approach (CMA). The energy budget is impacted significantly by how well the fenestration performs; thus, it is in the team’s best interest to use the most accurate performance values for compliance documentation. The CEC default value tables provide the lowest minimum compliant values, reference appendix NA-6 provides a slightly more complete calculation, and the CMA is an even more accurate method.

CMFNH Updates In our previous newsletter, we announced new additions to the program, including a revised incentive structure, updated training series, and new applications. CMFNH also has new certification requirements for energy consultants and verification requirements for high-rise projects, applicable to projects enrolled after January 1, 2010. Energy Consultants: Title 24 documentation submitted to the program must be authored by a 2008 CEPE (Certified Energy Plans Examiner). This certification is administered by the California Association of Building Energy Consultants (CABEC). Low-rise projects (three stories or fewer) must be signed by a Residential CEPE. High-rise projects (four stories or more) must be signed by a Non-Residential CEPE. For a full list of qualified consultants, consult the CEPE Roster. HERS raters: All CMFNH projects must be verified by a certified through CalCERTS or CHEERS as a California new construction HERS rater. CMFNH staff will no longer be verifying high-rise projects. Raters wishing to perform verification for highrise CMFNH projects must attend a CMFNH HERS Overview webinar. Developers looking to hire a CMFNH approved high-rise rater can contact Ashley Beals for a complete list of eligible raters.
LEED for Homes Mid-Rise Pilot The U.S. Green Building Council’s (USGBC’s) LEED for Homes program serves multi-family buildings three stories or lower. The USGBC also welcomes mid-rise projects into its pilot program.
