Codes & standards
Earlier this year, the National Fenes- tration Rating Council, Greenbelt, Md., launched its Component
Modeling Approach program for rating
and certifying nonresidential fenestration
products. It is a new approach, based on
pre-approved frame, glazing and spacer
components.
;e CMA Product Certification
Program is based on the existing NFRC
100/200 standards, and it is a more ef-
ficient method for making those calcula-
tions for nonresidential fenestration. As
such, CMA can be used in any state or
CMA arrives

town that requires ASHRAE 90.1-1999,
or later versions, because that standard
requires NFRC 100/200. Architects
can write specs immediately referencing
the CMA method for NFRC 100/200
calculations for curtain walls and glazed
walls. California and Washington
(specifically, Seattle) are already using
CMA, and CMA label certificates have
been issued for projects in Utah. ;e first
CMA label certificate went to Monett,

for the Life Sciences Research
