Integrated Heat and Moisture Calculation Tool for Building Envelopes
Design more energy-efficient building envelopes with the ability to design moisture control to improve energy efficiency of building envelopes.
The existing THERM software already had a large, established user community of professionals, academics, and researchers using the tool for rating windows and buildings. The team continues to use web-based forums to disseminate information and request testing from users. The research team is currently testing and doing verification of THERM-M and made the software tool more user friendly and fixing bugs in the software based on user feedback. The draft final report is under review. The team continues to inform potential users at conferences and industry gatherings regarding the project results. The web page with the latest version of THERM-M, as well as documentation, including technical documentation is located on the LBNL Therm 8 / Window 8 web page.

This project's purpose is to enhance the existing software tool widely used by building designers for thermal envelope modeling. The existing modeling software is used in Title 24 and Energy Plus development. It is an official tool by National Fenestration Rating Council, Passive House Institute, and Window Attachment Energy Rating Council. The new software tool, integrates both thermal and moisture modeling to improve envelope design and analysis for new construction and retrofit applications.
