Building automation systems form a centralized and computerized structure to manage and control a facility’s HVAC, lighting, plumbing, water supply, and security systems. Being able to control and adjust these systems on a central program interface allows for continuous optimization. However, where BMS/BAS suffer is the lack of real-time sub-metered data. Let’s further explore the need for real-time data in modern building automation systems.
The Problem with Constant Change
With a BMS or a BAS, a building’s mechanical and electrical functions are monitored by meters and sensors. Software connects these functions into one control system, so adjustments can be made in an instant to produce savings and improve efficiency. While programmed requirements dictate changes in the various building systems, we know that constant modifications and adjustments are inevitable. Building automation systems do an excellent job of detecting data anomalies and preventing major system defects before they occur. However, its software does not have robust enough data analytic capabilities. Furthermore, it does not capture enough real-time data points to recommend practical actions sooner.
Energy management systems are different from building automation systems, but many use these terms interchangeably. EMS collects and analyzes data from energy usage, finds areas for improvement, and continues to meter data to recommend the most efficient course of action. Advanced data analytics capabilities sift through previously logged data and real-time data to monitor building performance and detect performance issues. Integrating EMS real-time data metering with BAS allows building staff to identify and implement optimization tactics more timely.
Benefits from Better BAS
Being able to capture and assess real-time data from building assets, like the HVAC system, improves overall building and energy-efficiency. Having your BAS monitor temperatures, total energy consumption, flow rate, and indoor air quality from the HVAC system alone presents operators with a plethora of valuable information that affects the critical workings of a facility. A better BAS reports other building functions like time-of-day data usage, to implement plans for automated rerouting or to reduce energy into things like lighting during non-essential hours.
Real-time sub-metering data also lets businesses better predict utility prices. Additionally, building automation systems and energy management systems must be capable of network expansion as businesses want to add and monitor more metrics in their facilities. The more expansive the data-capturing abilities are, the better. The information from one facility, or nearby facilities, can give insight to area-wide energy-efficient practices, which a company may use to regulate their other buildings.
Lastly, an improved BAS with real-time data processing capabilities should have all this information readily available to the user on a cloud-based user interface. The software presents the data in an easy-to-understand or visual manner on tablets or other mobile devices. Operators who make sense of the information can recommend actionable and data-based improvements to building functions.
