Building Management Systems (BMS) have the capability to quietly collect vast amounts of information every second and, with dashboards in place and trends stored, these systems often appear to be operating exactly as they are supposed to. So why does building performance still drift in the wrong direction? Often the issue isn’t a lack of data, it’s a lack of ownership and focus.
The reality is that despite all this available data, very little of it is actually used to drive meaningful decisions. A BMS can only create value when the data is accurate, the outputs are easy to understand and someone is clearly responsible for acting on the insights.
Remove any one of these elements, and the system’s impact quickly fades. What remains is a familiar pattern across many buildings, systems that were once carefully installed and commissioned gradually become “install and forget.”
Over time, as sensors and alarms are ignored and dashboards become cluttered with information that no one has time to interpret, you find yourself left with a system that still collects data but no longer supports improved decision making.
Faced with underperformance, the instinct is often to add more sensors, more analytics tools or more layers of technology. But doing so rarely solves the problem and can actually make things worse by adding additional layers of complexity.
At global, it’s often the case that the biggest improvements we see in building performance don’t come from expanding systems but from simplifying them. With this in mind, the first step is improved clarity. Instead of overwhelming users with hundreds of data points, it can be beneficial to focus on a handful of key metrics that can make a significant difference to day to day operations.
The next step is to take proper ownership. Data without accountability is meaningless and with no individual or team in place to review outputs and act when required, there is an increased risk that important decisions won’t be taken or will be delayed for so long that there are financial consequences further down the line.
Finally, there is often a need to sharpen the focus. Not every trend needs analysis and the overall goal isn’t to monitor absolutely everything but to prioritise what will have the greatest impact.
Smart buildings have never been defined by how much data they generate, more so by how effectively that data is used. In many cases, the most important step isn’t investing in shiny new technology, it’s making better use of what already exists, and taking the decision to tap into that unused data ensures you are getting full value from your BMS.
