Component Modeling Approach Program
CMA Video
Overview:
The NFRC's new Component
Modeling Approach (CMA) Product Certification Program
enables whole product energy performance ratings for commercial
(non-residential) projects. The concept behind component modeling
is performance data from the three primary components that make
up a fenestration product are used for obtaining an overall product
performance rating.
Three primary components
used are:
- Glazing: : Glazing optical spectral and
thermal data from the International Glazing Database (IGDB)
- Frame: Thermal performance data of frame
cross-sections
- Spacer: Keff of spacer component geometry
and materials
The Component
Modeling Approach Software Tool (CMAST) establishes a set
of performance libraries of approved components (frames, glass,
and spacer) which can be accessed for configuring fenestration
products for a project, and obtaining a U-factor, Solar Heat Gain
Coefficient (SHGC), and Visible Transmittance (VT) rating for
those products, which can then be reflected in a CMA Label Certificate
for code compliance. CMAST is web-based as well as client-based.
The completed CMA program
and software tool will be useful in several ways for a vast array
of stakeholders in the industry:
- Generating performance ratings for bidding projects
- Ascertaining credible and accurate performance data
- Obtaining third party certification of overall product performance
for code compliance
