A system and method for realizing a building system is disclosed. In an embodiment, a holistic approach to a complex building system involves using high-productivity high-performance computing resources, such as cloud services, to manage a complex building system from building inception through to building operation. Because high-productivity high-performance computing resources are used, modeling, optimization, simulation, and verification can be performed from a single platform on a scale which heretofore has not been applied to complex building systems. Additionally, the holistic approach to complex building systems involves using a centralized database to manage all of the information related to a building system.
