NFRC Certified Approved Calculation Entities (ACEs)

An ACE is an individual who has attended an NFRC Calculation Training Workshop, completed and passed all necessary examinations, and has obtained a Certificate of Approval which qualifies him or her to carry out performance calculations of fenestration products for certification using the Component Modeling Approach (CMA).
