This is a two-dimensional polygon, with the origin at the point specified with RectangularGeometry/CartesianPoint. Please specify the program that generated the results using the id of the ProgramInfo element. Please specify how the values were obtained. Use the startTime attribute to define the start of the first Value element. This specifies the duration of time between each Value element. This is required if more than one Value element exists in a this Results element.

Ignore this element and all elements under it if you are not planning to use that method. Specifies which Conduction Time Series to use for the roof. See Table 21, page 29.30, 2001 ASHRAE Handbook, Fundamentals volume. Only used if the construction is a roof and you are using the RTS calculation method. Specifies which Conduction Time Series to use for the wall. See Table 20, page 29.28, 2001 ASHRAE Handbook, Fundamentals volume. Only used if the construction is a wall and you are using the RTS calculation method. Resistance of material The ShadeControl element is a bit complex, as shading control is handled differently in different simulation engines. Each child of ShadeControl represents a criteria to help determine if the shades will be open or closed. The resulting shade action should be a union of these. Example: You have included a ShadeSchedule, which is a 1 on weekdays and a 0 on weekends, and a SolarOnOpening. The shade will be drawn when the solar radiation on this opening is greater than SolarOnOpening and it is a weekday. Please specify the program that added this element. Use this element to define schedules for a shade. List of year schedules that make up an entire calendar year. Please specify the program that added this element. Value for one block of time. Divides a day evenly into number of ScheduleValue elements defined in DaySchedule. Example: If 12 ScheduleValue elements are defined, each will represent two hours Value of the outside drybulb temperature for when defining HVAC system lower supply reset temperature Value of the outside drybulb temperature for when defining HVAC system upper supply reset temperature Value of the upper supply air setpoint temperature for reset of cooling air or heating air temperature Value of the lower supply air setpoint temperature for reset of cooling air or heating air temperature Secondary supply air maximum flow rate Distance from outside surface of window to outside surface of wall Shading Coefficient: The ratio of total solar transmittance for the specified glazing system to the total solar transmittance for the standard reference glazing (1/8" clear). All data are global, with the assumption that positive Z is up, and if CADModelAzimuth is undefined or zero, positive X is East and positive Y is North. If CADModelAzimuth is defined it is the angle of positive Y to North, positive X is the vectorial product of Y and Z. If geometry is to be precise, use Longitude Latitude, and Elevation in the Location element to define the origin. Otherwise the origin is an arbitrary point. ShellGeometry is used to define a union of closed shells, where there is no intersection of any two of the given shells. Simulation parameters refer to simulation engine settings that are used during simulation run-time. These parameters are instructions for a simulation engine to take into account features such as simulation timestep (entered as a number of minutes which should be evenly divisible into 60, see timestep attribute), convergence limits (see ConvergenceLimits), and the version of the simulation engine (version attribute). This element intends to maintain a record of the settings used to run a simulation, which may be important if gbxml stores simulation results, as a user may wish to know what settings and version of the simulation engine were used for analysis. When element is a child of WindowType: The center of glass solar heat gain coefficient. When element is a child of Opening: The overall solar heat gain coefficient for the window assembly. Amount of solar radiation striking the opening before a shade is closed. A space represents a volume enclosed by surfaces. Planar polygon that represents the perimeter of space and whose area is equal to the floor area of the space. Planar polygons that represent the interior surfaces bounding the space and whose volume is equal to the volume of the space. spaceType represents how a space is used.

Global Unique ID from Industry Foundation Class (IFC) file. This element establishes the logical relation of a given part of the space ShellGeometry such that its PlanarGeometry is part of an interior surface bounding the space. Global Unique ID from Industry Foundation Class (IFC) file. If this attribute is set to true, the boundary is important in heat flow calculation. Connects the space boundary to a surface representing a building element (or representing the open air). If surface referenced by SpaceBoundary is adjacent to two spaces, then this references the corresponding SpaceBoundary of the opposite space.

The number of degrees from up that the outside of the surface is tilted in relation to the bottom-left corner. Time or period that results represent.
