8class Ceiling(InnerWall):
9 """Ceiling (InnerWall)
11 This class represents a ceiling and is a child of InnerWall()
13 Parameters
14 ----------
16 parent : ThermalZone()
17 The parent class of this object, the ThermalZone the BE belongs to.
18 Allows for better control of hierarchical structures. If not None it
19 adds this Ceiling to ThermalZone.ceilings.
20 Default is None.
22 Attributes
23 ----------
25 internal_id : float
26 Random id for the distinction between different elements.
27 name : str
28 Individual name
29 construction_data : str
30 Type of construction (e.g. "heavy" or "light"). Needed for
31 distinction between different constructions types in the same
32 building age period.
33 year_of_retrofit : int
34 Year of last retrofit
35 year_of_construction : int
36 Year of first construction
37 building_age_group : list
38 Determines the building age period that this building
39 element belongs to [begin, end], e.g. [1984, 1994]
40 area : float [m2]
41 Area of building element
42 tilt : float [degree]
43 Tilt against horizontal, default is 0.0
44 orientation : float [degree]
45 Azimuth direction of building element (0 : north, 90: east, 180: south,
46 270: west), default is -1, for horizontal ceiling
47 inner_convection : float [W/(m2*K)]
48 Constant heat transfer coefficient of convection inner side (facing
49 the zone), default is 1.7
50 inner_radiation : float [W/(m2*K)]
51 Constant heat transfer coefficient of radiation inner side (facing
52 the zone), default is 5.0
53 outer_convection : float [W/(m2*K)]
54 Constant heat transfer coefficient of convection outer side (facing
55 the ambient or adjacent zone). Currently for all InnerWalls and
56 GroundFloors this value is set to 0.0
57 outer_radiation : float [W/(m2*K)]
58 Constant heat transfer coefficient of radiation outer side (facing
59 the ambient or adjacent zone). Currently for all InnerWalls and
60 GroundFloors this value is set to 0.0
61 layer : list
62 List of all layers of a building element (to be filled with Layer
63 objects). Use element.layer = None to delete all layers of the building
64 element
65 other_side : ThermalZone()
66 the thermal zone on the other side of the building element (only for
67 interzonal elements)
68 interzonal_type_material : str
69 one of (None (default), 'inner', 'outer_ordered', 'outer_reversed')
70 describes as which kind of element the element is treated when loading
71 type elements. Caution: Make sure that the complimentary element of
72 the other zone is also changed accordingly if this is adapted manually
73 None: treatment based on project.method_interzonal_export_enrichment
74 'inner': InterzonalWall treated as InnerWall,
75 InterzonalFloor treated as Floor,
76 InterzonalCeiling treated as Ceiling
77 'outer_ordered': InterzonalWall treated as Wall,
78 InterzonalFloor treated as GroundFloor,
79 InterzonalCeiling treated as Rooftop
80 'outer_reversed': InterzonalWall treated as Wall,
81 InterzonalFloor treated as Rooftop,
82 InterzonalCeiling treated as GroundFloor, but with
83 reversed layers, resulting in the reversed
84 sequence of layers as for the complimentary
85 element declared as 'outer_ordered'
86 interzonal_type_export : str
87 one of (None (default), 'inner', 'outer_ordered', 'outer_reversed')
88 describes as which kind of element the element is treated when exporting
89 to Modelica. Caution: Make sure that the complimentary element of
90 the other zone is also changed accordingly if this is adapted manually
91 'inner': element will be lumped with InnerWall. No heat flow to the
92 zone on the other side will be modelled.
93 'outer_ordered': element will be lumped with OuterWall (OneElement
94 to FourElement export) or treated as border to an
95 adjacent zone (FiveElement export). Borders to the
96 same adjacent zone will be lumped.
97 'outer_reversed': like 'outer_ordered', but the lumping follows
98 VDI 6007-1 in reversed order, resulting in the
99 reversed order of resistances and capacitors as
100 for the complimentary element declared as
101 'outer_ordered'
103 Calculated Attributes
