Benchmarking Commissioning and Performance with a "Snapshot" of BMS Data


HVAC systems are the number one contributor to building operating expenses. Fortunately, these systems are regularly putting out data about how they are actually running, not just how they’re designed to; but if no one is paying attention to the data, then it’s worthless. While the use of BAS software and automated fault detection tools is increasing, building portfolio owners and facility managers remain hesitant and skeptical to undertake softwareenhanced retro-commissioning or ongoing monitoring based commissioning projects, because the outcomes are uncertain, timeframes for results are long, and there is no proof of ROI or results.

However, the solution that addresses these problems is simply to use actual BMS data to capture actual building operating conditions at over a short period of time. Perhaps counterintuitively, short analytics-based studies can reveal a lot about building conditions and improvement opportunities.

Short analytics surveys provide a snapshot in time of current building conditions and can be used as a starting point from which to improve. Facility teams have all the data they need to tackle large retro-commissioning projects with a sample baseline. A high-level and data-based snapshot of operational patterns for the building including scores for assets performance, occupant comfort, and energy efficiency, provides a clear estimate of how analytics can help meet a buildings’ target performance. It is a simple matter of knowing where you are before you begin, and importantly provides an incentive or motivation for retro-commissioning projects.
