an analysis of lighting controls indicating that 67% of light commercial buildings are controlled manually while 33% are operated with various other types of lighting controls. Lighting controls in commercial buildings can save an average of 20% of lighting energy. • Building Information & Energy Management Systems. Various studies indicate that the penetration of Energy Information Systems (EIS) and Energy Management Systems (EMS) are low compared to potential applications, and new ways to combine and extract value from these systems are also emerging. Additionally, the past five years has seen the growth of many new companies and applications involving energy information. Favorable trends in information systems, controls technologies, and associated costs suggest that market penetration of these technologies could be much higher. A technical analysis supporting AB80256 forecasts the potential to leverage the combined use of these EIS and EMS technologies (referred to in that study as `Building Information&Energy Management Systems', or BIEMS) As noted in that study, benefits at the core of the BIEMS concept include: o Energy visualization. Energy visualization represents the most minimalistic version of BIEMS. It uses basic utility, sub-meter, and other collected data to provide a basic visualization of energy consumption, sometimes in real time depending on data availability and frequency. o Energy analytics. Energy analytics go beyond energy dashboards and utilizes energy- related data to analyze building-level energy consumption characteristics. These analytics engines can perform a wide variety of functions such as uncovering opportunities to improve efficiency while supporting benchmarking efforts. o Operations and Facility Management. Operations and facility management services help automate and track maintenance and repair action items, including the automation of a building's maintenance schedule while reconciling operational changes in equipment/control set points. Some platforms also assist in managing capital expenditures related to equipment and asset management or helping customers evaluate any available energy supply options, including analysis of demand response opportunities. o Continuous Commissioning and Self-Healing Buildings. Continuous commissioning is a specialized application that several BIEMS vendors currently offer. This is closely related to operations management and typically requires the application of fault detection and diagnostics-based algorithms that track individual controls and equipment performance on an ongoing basis against ideal parameters to detect anomalies in system performance while reporting on any variance in performance. Building level energy savings estimates for comprehensive controls range from 10% for small building to 5% for large buildings and current saturations are estimated to be 37% across all commercial building types, indicating that significant potential exist for programs that combine both EIS and EMS systems.
