Abstract: Methods, systems, and articles of manufacture consistent with the present invention provide a digital design environment in which model information is delivered to a plurality of analysis programs that simultaneously provide real-time feedback to the user and to each other. An administrator/orchestrator program obtains a building information model and outputs a copy of at least a part of the building information model to at least two of the analysis programs. The administrator/orchestrator program receives an analysis result, which is based on an analysis of the copy of the at least part of the building information model, from each of the at least two analysis programs. The at least two analysis programs perform a respective analysis simultaneously to each other. At least two of the received analysis results are simultaneously displayed, such that effects in the received analysis results are simultaneously displayed in real-time responsive to changes in the building model.
