9class InnerWall(Wall):
10 """InnerWall class
12 This class holds information for an inner wall and is a child of Wall()
14 Parameters
15 ----------
17 parent : ThermalZone()
18 The parent class of this object, the ThermalZone the BE belongs to.
19 Allows for better control of hierarchical structures. If not None it
20 adds this InnerWall to ThermalZone.inner_walls.
21 Default is None.
23 Attributes
24 ----------
26 internal_id : float
27 Random id for the distinction between different elements.
28 name : str
29 Individual name
30 construction_data : str
31 Type of construction (e.g. "heavy" or "light"). Needed for
32 distinction between different constructions types in the same
33 building age period.
34 year_of_retrofit : int
35 Year of last retrofit
36 year_of_construction : int
37 Year of first construction
38 building_age_group : list
39 Determines the building age period that this building
40 element belongs to [begin, end], e.g. [1984, 1994]
41 area : float [m2]
42 Area of building element
43 tilt : float [degree]
44 Tilt against horizontal, default is 90.0
45 orientation : float [degree]
46 Azimuth direction of building element (0 : north, 90: east, 180: south,
47 270: west)
48 inner_convection : float [W/(m2*K)]
49 Constant heat transfer coefficient of convection inner side (facing
50 the zone), default 1.7
51 inner_radiation : float [W/(m2*K)]
52 Constant heat transfer coefficient of radiation inner side (facing
53 the zone), default 5.0
54 outer_convection : float [W/(m2*K)]
55 Constant heat transfer coefficient of convection outer side (facing
56 the ambient or adjacent zone). Currently for all InnerWalls and
57 GroundFloors this value is set to 0.0
58 outer_radiation : float [W/(m2*K)]
59 Constant heat transfer coefficient of radiation outer side (facing
60 the ambient or adjacent zone). Currently for all InnerWalls and
61 GroundFloors this value is set to 0.0
62 layer : list
63 List of all layers of a building element (to be filled with Layer
64 objects). Use element.layer = None to delete all layers of the building
65 element
66 other_side : ThermalZone()
67 the thermal zone on the other side of the building element (only for
68 interzonal elements)
69 interzonal_type_material : str
70 one of (None (default), 'inner', 'outer_ordered', 'outer_reversed')
71 describes as which kind of element the element is treated when loading
72 type elements. Caution: Make sure that the complimentary element of
73 the other zone is also changed accordingly if this is adapted manually
74 None: treatment based on project.method_interzonal_export_enrichment
75 'inner': InterzonalWall treated as InnerWall,
76 InterzonalFloor treated as Floor,
77 InterzonalCeiling treated as Ceiling
78 'outer_ordered': InterzonalWall treated as Wall,
79 InterzonalFloor treated as GroundFloor,
80 InterzonalCeiling treated as Rooftop
81 'outer_reversed': InterzonalWall treated as Wall,
82 InterzonalFloor treated as Rooftop,
83 InterzonalCeiling treated as GroundFloor, but with
84 reversed layers, resulting in the reversed
85 sequence of layers as for the complimentary
86 element declared as 'outer_ordered'
87 interzonal_type_export : str
88 one of (None (default), 'inner', 'outer_ordered', 'outer_reversed')
89 describes as which kind of element the element is treated when exporting
90 to Modelica. Caution: Make sure that the complimentary element of
91 the other zone is also changed accordingly if this is adapted manually
92 'inner': element will be lumped with InnerWall. No heat flow to the
93 zone on the other side will be modelled.
94 'outer_ordered': element will be lumped with OuterWall (OneElement
95 to FourElement export) or treated as border to an
96 adjacent zone (FiveElement export). Borders to the
97 same adjacent zone will be lumped.
98 'outer_reversed': like 'outer_ordered', but the lumping follows
99 VDI 6007-1 in reversed order, resulting in the
100 reversed order of resistances and capacitors as
101 for the complimentary element declared as
102 'outer_ordered'
104 Calculated Attributes
