modelWindow_ASHRAE140

Window with transmission correction factor, modelling of window panes

Extends from AixLib.ThermalZones.HighOrder.Components.WindowsDoors.BaseClasses.PartialWindow.

Information

Overview

The WindowSimple model represents a window described by the thermal transmission coefficient and the coefficient of solar energy transmission( with correction factors).

Concept

Phenomena being simulated:

  • Solar energy transmission through the glass
  • Heat transmission through the whole window

  • WschV 1995: 1,8 W/m2K
  • EnEV 2002: 1,7 W/m2K
  • EnEV 2009: 1,3 W/m2K
