Top 10: Building Energy Management Systems (BEMS)
Building energy management systems (BEMS) monitor and control a building’s energy use.
The solution is a key component of a smart building technology as it acts as the building’s brains.
BEMS can be responsible for functions including managing HVAC and lighting based on real-time data — ultimately contributing to increased efficiency and sustainability in a smart building environment.
Here, we run through 10 of the industry’s leading BEMS systems and how they are streamlining smart building efficiency.
