Component Modeling Approach Program

For the past 20 years, the National Fenestration Rating Council (NFRC) has provided a fair, accurate, and credible rating and labeling system for windows, doors, and skylights used in residential construction. Now NFRC is providing the non-residential market with a powerful and exciting online program known as the Component Modeling Approach (CMA).

What is CMA?
CMA is a groundbreaking concept in the non-residential fenestration industry. It offers performance information on fenestration components through an online database. This is essentially a library that houses data on a wide variety of fenestration components and is available all of the time from anywhere in the world.

CMA shows how changing one component affects overall energy efficiency and provides information on which components can be combined. Ultimately, the information obtained from CMA can be used to determine a whole product energy performance rating for a fenestration system.

This rating information is incorporated into a CMA Label Certificate for product validation. The label certificate lists the performance for all fenestration systems for a given building project.

Furthermore, any products certified for a particular project can be used in subsequent projects without recertification. Finally, components and certified products are maintained indefinitely in CMA.

How is CMA Organized?
CMA is organized into three primary components:




Optical/spectral data from the International Glazing Database

Thermal performance data of frame cross-sections

Thermal performance of spacer component materials

Why did NFRC create CMA?
NFRC developed CMA to:

What’s in it for me?
Architects and builders:

Building officials, state government employees, and other involved in code development and enforcement:

Government- and utility-run energy-efficiency programs:

Utah Valley Convention Center Finds Right Tool for the Job in NFRC’s CMA Program

“CMA was integral in streamlining the selection, certification, and code compliance processes for the fenestration on this project. It’s the kind of tool you can rely on to get things done easier than ever before.” --Todd Reynolds

Todd Reynolds wanted to simplify the process for achieving building energy code compliance and providing third-party certification for the glazed curtain wall surrounding the Utah Convention Center. He found just what he was looking for in the National Fenestration Rating Council’s (NFRC) Component Modeling Approach (CMA) Program. Click here for the full story
