Summary

The Center for Building Performance and Diagnostics (CBPD) has been developing a dynamic lifecycle building information model (DLC-BIM) focused on Total Building Performance to ensure best practices in sustainable and green architecture.

The DLC-BIM envisioned as part of the evolutionary process of innovation is to support multi-disciplinary and concurrent multi-domain building related design and operational decision making. The model structure is primarily based on the Industry Foundation Class (IFC) schema that will capture: (1) “static” building information generated during the design and construction process and shared among the design architects and engineers, particularly to support building performance predictions using various building simulation tools (e.g., energy, CFD, lighting, acoustics, etc.), benchmark evaluations (e.g., LEED), and advanced design optimization; (2) “dynamic” (operational) building information generated from large-scale occupancy detection and environmental sensing network for on-going commissioning, whole building performance monitoring, and advanced adaptive controls based on occupant behavioral studies.

Specific applications include Occupancy Behavior-based Predicted HVAC Control; Passive, Active and Hybrid HVAC and Controls; Dynamic 3-D Architectural Model and Sensor Information Visualization; Representing and Evaluating Performance Metrics; and Embodied Energy and Carbon Content in Primary Building Materials.
