What is the AERC?
AERC is an independent, public interest organization whose
mission is to provide consumers with credible, relevant, and
comparable information about window attachments and their
performance.• AERC members include
• Public Interest Groups• National Labs• Commercial Labs• Product Manufacturers• Fabric Manufacturers• Utilities

Why is AERC Necessary?
• Window attachments can save energy• However, many consumers are unaware of their
energy‐saving capability
• Consumers have no way to compare the energy performance of attachments
• Utility program managers also benefit from standardized rating system and energy performance information

Why Do Manufacturers Participate?
• Third‐party certification validates claims• AERC label differentiates window attachments• Generates standardized product performance ratings– Enables direct product comparisons
• Access to utility pilots and incentives

LBNL develop technical modeling in WINDOW and THERM
Technical Committee reviews analysis and software updates
Technical Committee develops rating standards
Certification Committee develops Certification standards
Reviewed and approved by AERC members and Board
Certification begins
‐ Consensus based approach to standards development‐ Rely on industry and national lab technical knowledge
‐ AERC is public interest organization so standards must reflect that

Product Simulation
• Simulator uses product information to develop models using WINDOW and THERM and produce Energy Performance ratings through AERCalc– Involves specifying product geometry based on literature or drawings supplied to the Simulator
• Grouping products reduces simulation time and cost

Manufacturer Review
• Simulator provides manufacturer with results of simulations – U‐factor, SHGC, VT, EPH, EPC
• Manufacturer reviews, confirms results, and instructs simulator to submit products for listing in the AERC CPD–Work with simulator to provide any additional information (e.g. marketing description)

• Goal: basic program in place by end of 2019• Initial stages of development
– Fabrics and material properties already established– Identifying window attachment energy‐related information needs in the commercial space
• Building relationships with and gaining input from commercial stakeholders:
Architects Interior designers
Building owners
Building managers
Specifiers Contractors Commercial attachment

Energy Performance
EP value Signifies: The window attachment installed over baseline window
<0 Use more energy on an annual basis than if it had no attachment at all
0 No net impact on the energy performance of the home on an annual basis
>0 and 100 Improves the net annual energy performance of the home
100 Performance is equivalent to a net zero energy window
>100 Net annual energy producer compared to a net zero energy window
