A base case was created in Rhino; using Grasshopper and Firefly, a simple digital model responded to lighting-levels detected by a photoresistor on an Arduino board. The case study was duplicated using Revit Architecture, a popular BIM software, and Dynamo, a visual programming environment, in an innovative application. Another case study followed a similar procedure by implementing the Revit API directly instead of using Dynamo. Then the process was reversed to demonstrate that not only could data could be sent from sensors to change the 3D model, but changes to parameters of a 3D model could effect a physical model through the use of actuators. It is intended that these virtual/physical prototypes could be used as the basis for testing intelligent façade systems before constructing full size mock-ups.Keywords: Environmental sensors; BIM; building information model; visual scripting; Dynamo; intelligent facades.

A building information model (BIM) contains data that can be accessed and exported for other uses during the lifetime of the building especially for facilities management (FM) and operations. Working under the guidance of well-designed BIM guidelines to insure completeness and compatibility with FM software, architects and contractors can deliver an information rich data model that is valuable to the client. Large owners such as universities often provide these detailed guidelines and deliverable requirements to their building teams. Investigation of the University of Southern California (USC) Facilities Management Service's (FMS) website showed a detailed plan including standards, file names, parameter lists, and other requirements of BIM data, which were specifically designated for facilities management use, as deliverables on new construction projects. Three critical details were also unearthed in the reading of these documents: Revit was the default BIM software; COBie was adapted to help meet facilities management goals; and EcoDomus provided a display of the collected data viewed through Navisworks. Published accounts about the Cinema Arts Complex developed with and under these guidelines reported positive results. Further examination with new projects underway reveal the rapidly changing relational database landscape evident in the new USC "Project Record Revit Requirement Execution Plan (PRxP)".
