ABSTRACT
One great thing collecting building data into an information technology (IT) application is that can do things with it without interfering with ongoing operations. The advantages to separately collecting data for business applications: The advantages of a separate building representation, collected into its own data warehouse are examples of how an IT system adds business value. In the end, the business value from an IT-based building system comes from the ability to make better decisions, increase productivity, improve customer service, and other business. When more people start using information to understand how the buildings and systems they work with daily actually function, good things happen. The business value is only achieved when they share what they know, communicating between building systems and with their owners. The control system representation of a building is different from an IT representation at both the technical and end-user level.
