In addition to implementing ISO 15099 algorithms in WINDOW7 and THERM7, we have added additional capabilities to WINDOW7.
- See: ANSI Standards Store: ISO 15099:2003.
- "Thermal performance of windows, doors and shading devices - Detailed calculations.".
- The algorithms in WINDOW6 and THERM6 follow the procedures presented in ISO 15099:.
- WINDOW7 and THERM7 implement the ISO 15099 algorithms: Technical Documentation Algorithm Documentation When running them in later versions of THERM, make sure to regenerate boundary conditions, and when using them in later versions of WINDOW, make sure to recalculate all the results. There may be a few slight difference between the files and those shown in the manual (for example the spacer in the aluminum slider example).
- These sample files are from the NFRC THERM 5.2 / WINDOW 5.2 Simulation Manual.
- Sample DXF and THERM files ( Example THERM and DXF Files.zip) - some of these are referenced in the THERM 7 User Manual Drawing Tips excerpt above.
- Using the Updater Function to Download a New Version.
- Viewing R-values Instead of U-factors in THERM 7.
- Displaying Surface Condensation Potential in THERM 7.
- it is now a multi-threaded process which allows it to take advantage of multi-core processors.
