[docs]class GroundFloor(OuterWall): """GroundFloor class This class holds information of a GroundFloor and is a child of OuterWall() 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 GroundFloor to ThermalZone.ground_floors. Default is None. Attributes ---------- internal_id : float Random id for the distinction between different elements. name : str Individual name construction_type : 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), orientation -2.0 inner_convection : float [W/(m2*K)] Constant heat transfer coefficient of convection inner side (facing the zone), default 1.7 inner_radiation : float [W/(m2*K)] Constant heat transfer coefficient of radiation inner side (facing the zone), default 5.0 outer_convection : float [W/(m2*K)] Constant heat transfer coefficient of convection outer side (facing the ambient or adjacent zone), default 0.0 outer_radiation : float [W/(m2*K)] Constant heat transfer coefficient of radiation outer side (facing the ambient or adjacent zone), default 0.0 layer : list List of all layers of a building element (to be filled with Layer objects).
