Heat Transfer Modeling Software
A Windows-based program used for modeling and calculating heat flow through framing systems.
THERM 7.4.4 will expire as an NFRC approved software program on June 30, 2021 for new certifications, and re-certifications; THERM 7.7.10 may be used begining March 13, 2020. THERM 7.4.4 may continue to be used by the laboratories to revise an existing product line until its expiration, except for product options that require use of the CGDB. THERM 6.3 may be used indefinitely for frame/spacer components in the CMA Program.
A Windows-based program that calculates the overall thermal transmission of window systems.
WINDOW 7.4.14 will expire as an NFRC approved software program on September 14, 2020 for new certifications, and re-certifications; WINDOW 7.7.10 may be used begining March 13, 2020. WINDOW 7.4.14 may continue to be used by the laboratories to revise an existing product line until its expiration, except for product options that require use of the CGBD. WINDOW 6.3 may be used indefinitely for glazing components in the CMA Program.
The Window 7 thermochromic glass layer utility.exe (download link below) can be used to merge a set of laminate entries in a W7 library into a single, dynamic, (thermochromic) glass layer for use with an Environmentally Controlled Dynamic Glazing(ECDG) product. The use of this tool is detailed in Section 8.20 of the THERM 7 / WINDOW 7 NFRC Simulation Manual.
When installing the software, please download both files. Initially use the “W7 thermochromic glass layer utility.EXE” file in the “Pleotint.ZIP” file. If you have any difficultly, use the “SETUP.EXE” file in the “Pleotint LBNL Window utilities Setup.ZIP” file.
A Windows-based program for rating non-residential fenestration products, consisting of both a web application and client application.
This software is only authorized for use with the CMA Product Certification Program. The annual cost for the CMAST is $1000. Users will be charged a prorated amount based on the timing of their registration. The prorated invoice will be forwarded approximately 30 days after download and registration. Thereafter, annual $1000 invoices will be issued in January. Users may terminate their participation by notifying staff email@example.com
COMFEN is a tool designed to support the systematic evaluation of alternative fenestration systems for project-specific commercial building applications. COMFEN provides a simplified user interface that focuses attention on key variables in fenestration design. Under the hood is Energy Plus, a sophisticated analysis engine that dynamically simulates the effects of these key fenestration variables on energy consumption, peak energy demand, and thermal and visual comfort. The results from the Energy Plus simulations are presented in graphical and tabular format within the simplified user interface for comparative fenestration design cases to help users move toward optimal fenestration design choices for their project.
