Building management systems have evolved from thermostats on the wall to sophisticated control systems run by advanced software. Today’s systems can precisely monitor and control mechanical systems and building functions from virtually anywhere in the world as well as collect and compute system performance data and trends.
But, much like all technological advancements, questions arise, such as what data are most useful, how should it be analyzed, and how can HVACR contractors best use that information. Also, in the age of cyberterrorism, contractors are tasked with ensuring building control systems and software are secure and safe from the threat of hackers.
Data: know the goal
When it comes to data, it’s important to understand the type and amount of data that can be gathered by building management software. It’s equally important that contractors comprehend the strategies customers are trying to employ at any given site. If the goal is to monitor simple operational expenses, the system may collect data from the energy meters. At a more complex site, a building operator might want to add lighting status and occupancy counts. Universities and other large campuses may be looking at centralizing or optimizing their overall operating plans and may want to include data, such as pump speeds, refrigerated water flow, operating loads, and other parameters.
