The more advanced the BEMS, the better the future of energy management in buildings.
FREMONT, CA: When managing a building, whether it’s a school, hospital, manufacturing facility, retail store, office building, or any other physical space, it is safe to assume that it is not as energy-efficient it could be. Commercial buildings have been found to waste, on average, 30 o=percent of the energy they consume; unless they have taken steps to address this loss, the efficiency rate likely is not far off. Today, there are several ways to use energy management tools from the start that afford improved control over energy use, a building energy management system (BEMS). Read on to know more.
[vendor_logo_first]Several existing buildings continue to depend solely on BMS as a technique for energy management. However, while BMS is still an effective method to manage building environments, it has limited capacities and cannot offer much value beyond simple scheduling and automation. If the commercial building only has a BMS, consider combining it with an Internet of Things (IoT) solution for a more advanced energy management strategy.

Although BEMS is similar to BMS, BEMS is a slightly more sophisticated energy management system for buildings. BEMS offers monitoring and information specifically focused on systems involving energy use and demand to help managers create savings. A BEMS can receive the external signal from the utility and send control instructions to building systems in response. BEMS may direct lights to dim in specific areas to mitigate the overall load, increase the temperature, and shift from utility generation to a battery storage system. BEMS can also monitor, aggregate, and process data at a basic level to inform logic-based responses. BEMS are useful and are used in a reactionary manner to address problems after the fact.
With the right data—collected, correlated, and analyzed by the IoT—it’s possible to design the optimal energy management approach for cost savings. This IoT-based strategy is more effective for energy management than BMS and BEMS because the energy consumption of a commercial building is changing based on several dynamic conditions. There is no static model of energy use. Better energy management relies on having the right data at the right time, enabling building managers to be flexible in their approach to energy reduction.
