modelVDI6007WithWindow
Equivalent air temperature as defined in VDI 6007 Part 1 with modifications
Extends from BaseClasses.PartialVDI6007 (Partial model for equivalent air temperature as defined in VDI 6007 Part 1).
Information
This model is a variant of the calculations defined in VDI 6007 Part 1. It adds a second equivalent air temperature for windows in case heat transfer through windows and exterior walls is handled separately in the Reduced Order Model. The sum of all weightfactors for windows should be one as well as the sum for all wall elements.
