Information

Model for the indoor emissive power that hits a window. The computation is according to TARCOG 2006.

Revisions

  • January 29, 2019, by Michael Wetter:
    Removed parameter T03 which is already inherited from the base class.
  • May 30, 2014, by Michael Wetter:
    Removed undesirable annotation Evaluate=true.
  • June 27, 2013, by Michael Wetter:
    Changed model because the outflowing radiosity has been changed to be a non-negative quantity. See track issue #158.
  • February 10, 2012, by Wangda Zuo:
    Fixed a bug in the temperature linearization.
  • November 3, 2010, by Michael Wetter:
    First implementation.
