It might surprise some to learn that building management systems (BMS) are not a 21st-century invention. The initial rudimentary BMS originated nearly 150 years ago with the development of the first thermostats used to manage boiler room temperatures. Building management has evolved extensively over the decades, from compressed air apparatus to electric to the now ubiquitous digital controls.
Now 60% of all large (more than 50K square feet) U.S. commercial buildings use some form of a BMS to automate lighting, heating, ventilation, air conditioning, security, and more. When facilities managers decide to move from manual operating and data compilation processes, the temptation can be to start cautiously by adding single-point solutions. Devices that automate one process, such as the HVAC system, can provide useful data and operational ease in that area. However, a comprehensive BMS can offer longer-term efficiencies through economies of scale and seamless communication between all critical systems.
There are other, sometimes less obvious, attributes to consider when identifying the right BMS for your building versus one-off applications. Selecting a new BMS or upgrading an obsolete one provides an opportunity to build in other resources that are just as valuable, such as robust cybersecurity, having a team of experts connected to the platform, support for analog equipment, and responsive customer service.
Adding an Extra Layer of Security Protects Smart Buildings
As physical structures become increasingly integrated with technology, cyberattacks are also rising and can cause expensive damage that negatively affects a brand’s reputation. Countless digital devices within a built space constantly share information, including administrative systems that share access with vendors and contractors, HVAC and smart lighting systems, and even elevators, key cards, and security cameras. A full inventory and assessment of all operational technology (OT) will provide a baseline of connected equipment that can be monitored for security. Firewalls, multi-factor authentication, and segmented networks that block unauthorized gateways should be fully integrated within a BMS.
Building Controls Include Hardware and Software, so Seamless Communication Matters
A true BMS manages not only hardware but also software, which is crucial to creating a real-time view of a building’s status. Sensor arrays, actuators, and controllers are the first line in monitoring and collecting data. Powerful operational control happens when there is a seamless bridge between the hardware that compiles data and the software that determines what next steps to take based on that data.
Full Customer Service Provides a Crucial Step to Faster ROI
Most BMS solutions have a lifespan of about a decade. Selecting the right one for your particular scenario can mean the difference in millions of dollars in better energy management and human resources. A systems integrator dedicated to assisting a facility team at launch can help bring higher efficiencies and a quicker ROI. And, a company’s mission will likely evolve over the life of a BMS, along with the regulatory climate. Choosing a BMS that can adapt to advancing technologies and new guidelines can further extend the life of your system.
The ideal integrated BMS will monitor and respond to real-time building conditions through a 360-degree lens. This means keeping the internal environment within a desired range for occupant comfort, analyzing system performance, automation for responsive lighting, and averting expensive device malfunctions, all while managing energy and maintenance expenditures.
While point solutions can provide targeted applications as a building becomes digitized, over time, this piecemeal approach can hinder innovation, efficiency, and growth. Facilities managers who leverage tools like artificial intelligence, the Internet of Things, machine learning, and cloud computing are finding unprecedented levels of control and cost savings that only a BMS can bring to the table. As buildings shift into a more autonomous digital realm, a comprehensive BMS can provide today’s facility teams with the comprehensive tools needed to create more responsive, safer, and comfortable structures.
