Wausau Window and Wall Systems is among the first manufacturers to earn Approved Calculation Entity certification through the National Fenestration Ratings Council (NFRC). Accordingly, Wausau says it is now in a position to provide offer its customers reassurance to customers who want to fully understand new energy code requirements.
NFRC labels are currently mandated only in California and Washington, but nationwide adoption is likely.
According to Jessica Ferris, CMA’s Program Manager, ACE-certified users analyze performance data for non-residential fenestration energy ratings. By accessing NFRC's Component Modeling Approach software tool, CMAST, they are able to review libraries of approved frames, glass and spacer components.
These libraries help users configure fenestration products for a project, and allow them to obtain a U-factor, solar heat gain coefficient and visible transmittance rating for those products. Performance values are then compared to the energy requirements of local codes, such as California's Title 24, to determine compliance.
