The Complex Glazing Database (CGDB) is a database, developed by Lawrence Berkeley National Laboratory (LBNL), which stores thermal and optical performance information about materials used in window attachments as well as the geometry of window attachment products.
CGDB Materials Library
The CGDB Materials Library houses thermal and optical property data on materials used in window attachment products (other than storm windows and window panels). Storm windows and other attachment products using glazing materials must have those materials measured and submitted to the IGDB through the National Fenestration Rating Council. All other materials (e.g. fabrics, PVC, wood) are submitted to the CGDB Materials Library through AERC using the steps described below. The data are measured in accordance with AERC standards by test labs approved through the LBNL Inter-laboratory Comparison (ILC).
How to Submit Materials to the CGDB Materials Library
An approved test lab must conduct measurements for submission to the CGDB Materials Library. The material manufacturer determines who will submit data to AERC for listing in the Materials Library. In some cases, test labs may be responsible for submitting materials for listing. Please review all CGDB policies above prior to submission of any material listings to ensure you are following proper procedures.
#2. Identify products and type of listing. Material manufacturer determines whether to submit temporary or full material listings to the CGDB Materials Library based on requirements in AERC 1.1. Full listings require three manufactured lots to obtain 18 samples for tolerance testing. In the event that three manufactured lots are not available for a material, a temporary listing can be submitted based on testing of one manufactured lot. Temporary listings must be updated within 18 months to include testing of 18 samples across three manufactured lots.
#3. Test lab conducts measurements. Material manufacturer ships required samples to test lab or provides to ILC-approved in-house lab, which tests the materials according to AERC 1.1 procedures and sends results to the material manufacturer for review.
#4. Submit materials to AERC and pay listing fees. The material manufacturer’s designated submitter submits the necessary documentation to email@example.com. Documentation includes a homogeneity/ tolerance report, a test report with full measured data from the representative sample, a data submission spreadsheet, and a signed submitter affirmation. AERC reviews the submission for completeness and issues invoice to the material manufacturer based on AERC membership status and number of listings. Material manufacturer pays invoice to AERC (Credit Card, Wire, or Check).
#5. Technical and peer review. Upon payment of fees, the submission undergoes technical review by LBNL and then is included in the next peer review, in which relevant stakeholders review the performance information and submit questions to LBNL.
#6. Materials listed. Once the submission passes the technical and peer review, the material listing(s) are publicly released in the next version of the CGDB (see CGDB Release Schedule )
a. If submitted listings were temporary, material manufacturer must submit complete data within the time period identified in AERC 1.1.
#2. Submit Secondary Listing Agreement and Data Submission Spreadsheet and pay listing fees. The material manufacturer’s designated submitter submits the necessary documentation to firstname.lastname@example.org. AERC reviews the submission for completeness and issues invoice based on AERC membership status and number of listings. Manufacturer pays invoice to AERC (Credit Card, Wire, or Check).
#3. Materials listed. Once the submission passes the review, the material listing(s) are publicly released in the next version of the CGDB (see CGDB Release Schedule ).
CGDB Shading Layer Library
The CGDB Shading Layer Library houses simulation files that model the geometry of window attachment products along with the associated material. The material used in the shading layer must be listed in the latest version of the CGDB or IGDB. Upon certification of a window attachment product, ACEs should submit the shading layers to the CGDB Shading Layer Library.
How to Submit Materials to the CGDB Shading Layer Library
Participation and listing fees do not apply to the Shading Layer Library of the CGDB. No registration is necessary.
The submission requirements for a shading layer library vary depending on the attachment product type. See AERC 1 for definitions of each product type. Storm windows do not need to be submitted to the CGDB Shading Layer Library.
Submission information for the remaining Phase 1 product types will be added to this page in March 2018. Please contact email@example.com with any questions.
AERC CGDB Policies
Materials Policy. Only Phase 1 (cellular shades, blinds, solar screens, storm windows, roller shades, and pleated shades) residential attachment products whose materials have been tested in accordance with AERC program requirements and listed in the Complex Glazing Database (CGDB) or International Glazing Database (IGDB) may be simulated, rated, and submitted for AERC certification. Materials used for simulations must be tested in accordance with AERC 1.1, comply with all AERC policies and procedures, and carry the AERC mark (“@”) in the CGDB or must be listed in the IGDB if a glazing material. All materials listed in the IGDB are eligible for use in attachment products submitted for AERC certification.
Manufacturer Policy. Materials listed in the Complex Glazing Database (CGDB), if carrying the AERC mark, @, must be listed under the name of the original manufacturer of the product. No product in the CGDB may be re-branded under a company name different from that of the original manufacturer without the express permission of the original manufacturer. If a secondary company wishes to have a product they do not directly manufacture listed under their name, they must submit a letter signed by an authorized representative from the original manufacturer and the secondary company and clearly listing the original model numbers and the equivalent secondary model numbers that will appear in the CGDB. Any product found to be in violation of this policy may be subject to suspension or removal from the AERC Product Certification Program.
