Buildings.Rooms.Constructions.Construction
Model for an opaque construction that has no window
layers 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.Rooms.Constructions.BaseClasses.PartialConstruction (Partial model for exterior construction that has no window).

Buildings.Rooms.Constructions.ConstructionWithWindow
Model for an opaque construction that has one window embedded in the construction
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:
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 record layers to access the material properties
of the opaque construction.
win, which uses the model
Buildings.HeatTransfer.Windows.Window to compute
the heat transfer through the glazing system.
This model uses the record glaSys 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=A-AWin.
