Approved Calculation Entities (ACEs)

An ACE is an individual who has attended an Approved Calculation Entity 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 and issue label certificates using the Component Modeling Approach Software Tool (CMAST).

For more information on becoming an ACE, please contact jpadgett[at]

What is an ACE Organization? It is a legal entity owned by the ACE, or that employs or contracts with the ACE to perform CMA calculations and issue certified CMA Label Certificates.
