class Floor(InnerWall):
"""Floor (InnerWall)
This class represents a floor and is a child of InnerWall()
Parameters
----------
parent : ThermalZone()
The parent class of this object, the ThermalZone the BE belongs to.
Allows for better control of hierarchical structures. If not None it
adds this Floor to ThermalZone.floors.
Default is None.
Attributes
----------
internal_id : float
Random id for the distinction between different elements.
name : str
Individual name
construction_data : str
Type of construction (e.g. "heavy" or "light"). Needed for
distinction between different constructions types in the same
building age period.
year_of_retrofit : int
Year of last retrofit
year_of_construction : int
Year of first construction
building_age_group : list
Determines the building age period that this building
element belongs to [begin, end], e.g. [1984, 1994]
area : float [m2]
Area of building element
tilt : float [degree]
Tilt against horizontal, default is 0.0
orientation : float [degree]
Azimuth direction of building element (0 : north, 90: east, 180: south,
270: west), default is -2, for horizontal floor
inner_convection : float [W/(m2*K)]
Constant heat transfer coefficient of convection inner side (facing
the zone), default is 1.7
inner_radiation : float [W/(m2*K)]
Constant heat transfer coefficient of radiation inner side (facing
the zone), default is 5.0
outer_convection : float [W/(m2*K)]
Constant heat transfer coefficient of convection outer side (facing
the ambient or adjacent zone). Currently for all InnerWalls and
GroundFloors this value is set to 0.0
outer_radiation : float [W/(m2*K)]
Constant heat transfer coefficient of radiation outer side (facing
the ambient or adjacent zone). Currently for all InnerWalls and
GroundFloors this value is set to 0.0
layer : list
List of all layers of a building element (to be filled with Layer
objects). Use element.layer = None to delete all layers of the building
element
Calculated Attributes
