Buildings.ThermalZones.Detailed.Constructions.Construction
Model for an opaque construction that has no window
Information
This model is used to compute heat transfer through opaque constructions inside the room model. The model uses the recordlayers
to access the material properties
of the opaque construction. The heat transfer is computed in the instance
opa
, which uses the model
Buildings.HeatTransfer.Conduction.MultiLayer.
Extends from Buildings.ThermalZones.Detailed.Constructions.BaseClasses.PartialConstruction (Partial model for exterior construction that has no window).

Modelica definition
Buildings.ThermalZones.Detailed.Constructions.ConstructionWithWindow
Model for an opaque construction that has one window embedded in the construction
Information
This model is used to compute heat transfer through constructions with windows inside the room model.
The model consists of the following two main submodels:

The instance
opa
, which uses the model Buildings.HeatTransfer.Conduction.MultiLayer to compute the heat transfer through the opaque part of the construction. This model uses the recordlayers
to access the material properties of the opaque construction. 
The instance
win
, which uses the model Buildings.HeatTransfer.Windows.Window to compute the heat transfer through the glazing system. This model uses the recordglaSys
to access the material properties of the glazing system.
The parameter A
is the area of the opaque construction plus the window.
The parameter AWin
is the area of the glazing system, including the frame.
The area of the opaque construction is assigned internally as AOpa=AAWin
.
Extends from Buildings.ThermalZones.Detailed.Constructions.BaseClasses.PartialConstruction (Partial model for exterior construction that has no window).
