Approximately 84% of the life cycle energy use of a building is associated with operating the building rather than the materials and energy used for construction. Building owners also face pressure to improve safety, security, occupant comfort and health, and to make buildings responsive to a new smart electrical grid that increasingly relies on the use of intermittent renewable energy sources. Modern integrated building automation and control systems create an environment rich with sensor data and distributed control intelligence that can be applied to solve these problems through the application of machine learning, intelligent optimization techniques, automated fault detections and diagnostics, automated commissioning tools, and management of local generation and flexible loads in response to changing electric grid conditions.
