ID pointing at an air loop equipment object ID pointing to an air loop Minimum air temperature before shades are closed. Reflectance of solar radiation Alternative energy source Specifies the area of the space or building. This value should be equal to the area enclosed by the physical boundaries of the space, as defined by the intersection of the horizontal plane at the highest floor height and the volumetric model's vertical interior surface planes. Building area should be the sum of space areas whose PeopleNumber element values are greater than zero. Polygon azimuth. The direction of the outward normal for the polygon (surface or opening) defined in RectangularGeometry element. Azimuth is measured in degrees clockwise from North, where North = 0 degrees.

ID for the weather data used for a heating design day ID for the weather data used for a cooling design day Global Unique ID from Industry Foundation Class (IFC) file. This is the x, y, and z distances from the origin. This element must have three Coordinate elements when representing 3-d space, which represent x, y and z in order. This element must have two Coordinate elements when representing 2-d space. IfcCartesianPoint Cooling degree days. CDD is calculated as the number of degrees a mean daily temperature is above a value (specified as the Temperature element), for each day. For example, if the mean temperature in a region rises to 77 degrees for three days during a year, the rest of the time staying below 75, and the Temperature element is set at 75, then CDD = 6. Cooling degree day value This is an element from ifcXML that describes a collection of faces that make up a closed shell.

Ignore this element and all elements under it if you are not planning to use that method. Specifies the number 1 to 13 to use for a roof. See Table 29 page 26.34, 1989 ASHRAE Handbook, Fundamentals volume. Specifies the wall group code A to G to use for a wall. See Table 31, page 26.36, 1989 ASHRAE Handbook, Fundamentals volume. Specifies the effective roof color, which depends on the actual color and whether the location is industrial or rural. See page 26.34, 1989 ASHRAE Handbook, Fundamentals volume. Specifies whether or not a roof has a suspended ceiling under it. See table 29, page 26.34, 1989 ASHRAE Handbook, Fundamentals volume.

The coefficient of utilization is the ratio of luminous flux on a work plane to the luminous flux emitted by the lamps alone. Room cavity ratio is a measure of the room cavity proportions. Conductivity as a function of temperature A Construction is a combination of layers, such as a wall or a roof Reference to layers that comprise this construction. Multiple LayerId's order is important and specifies the layering of the layer's referenced materials. The first Surface/AdjacentSpaceId entered will determine how the referenced construction layers are ordered with the first construction layer being in contact with the outside or 2nd Surface/AdjacentSpaceId listed and the last layer in contact with the first Surface/AdjacentSpaceId listed. Use this attribute to reference objects in the DOE2 library The Control element should be used for describing how this equipment is controlled. This is the an x, y, or z length measurement from the origin. IfcLengthMeasure Denotes the time this file has been created, as well as the person and program used to create this file.
