Building Results Data Fields (InfoWorks)

Building results are displayed in the Object Properties Window while viewing a replay of a simulation.

Time varying results are shown with the field name in an alternate colour on the grid. Non-time varying results have the field name in the normal black type.

Database Table Name: _IWR_BUILDING

Summary results (non-time varying)

Field Name	Description	Units	Database Field
Effective rainfall	This is the total depth of rainfall on impervious surfaces, minus evaporation.	Y	EFFRAIN
Rainfall profile	The rainfall profile applied to the building during the simulation. During most simulations this will be the profile entered in the Rainfall profile field. When using a Rainfall Event containing rain-gauge boundary data, this profile depends on which rain-gauge boundary contains the drainage node.		RAINPROF
Evaporation profile	The evaporation profile applied to the building during the simulation. This is the profile that is specified on the Evaporation profile field in the building's properties.		EVAPPROF
Exceedance volume	Applicable to a building that has its Limit drain to capacity box checked. The total volume, in excess of the Capacity limit, from the building that is either lost or directed either to the 2D element where its Drains to node is located or to its perimeter.	VO	V_EXCEEDANCE
Runoff	The maximum flow from the building roof.	Q	RUNOFF
Total outflow	The maximum total outflow (runoff and SUDS control net outflow) from the building	Q	QCATCH
Exceedance flow	Applicable to a building that has its Limit drain to capacity box checked. The maximum flow, in excess of the Capacity limit, from the building that is either lost or directed either to the 2D element where its Drains to node is located or to its perimeter.	Q	Q_EXCEEDANCE
Max enclosed volume	The maximum volume within the building experienced during the simulation	VO	MAXVOLUME2D
Max flow into building	The maximum flow into the building experienced during the simulation	Q	MAXFLOW2D
Max highest depth	The maximum highest depth value experienced during the simulation.	Y	MAXHIGHDEPTH2D
Max highest elevation	The maximum highest elevation value experienced during the simulation. A null value will be displayed if elements associated with the building are dry throughout the simulation.	Z	MAXHIGHELEVATION2D

Time-varying results

Field Name	Description	Units	Database Field
Total outflow	The total outflow (runoff and SUDS control net outflow) from the building	Q	QCATCH
Exceedance flow	Applicable to a building that has its Limit drain to capacity box checked. The flow, in excess of the Capacity limit, from the building that is either lost or directed either to the 2D element where its Drains to node is located or to its perimeter.	Q	Q_EXCEEDANCE
Enclosed volume	The Enclosed volume result is calculated as the sum of water depth x element area of all 2D mesh elements within the building boundary.	VO	VOLUME2D
Flow into building	For each 2D mesh element that the building polygon intersects: The component of the unit flow normal to the boundary is determined The unit flow component is multiplied by the length of the boundary segment intersecting the element The flow into the building is calculated by summing the flows across each boundary segment. Flow directed into the building is counted positive and flow directed out of the building is counted negative.	Q	FLOW2D
Highest depth	The maximum of the depth values, at a given timestep, of all the 2D mesh elements inside building boundary	Y	HIGHDEPTH2D
Highest elevation	The maximum of the elevation values, at a given timestep, of all the 2D mesh elements inside the building boundary. A null value will be displayed for timesteps at which the elements associated with the building are dry.	Z	HIGHELEVATION2D
