Using the Building Automation System to Commission Buildings
This article proposes a simple, logical process for commissioning hvac systems through building automation systems (bas'). Commissioning has been widely promoted as a valuable process to ensure that buildings' hvac systems perform as originally envisioned. This is particularly true for complex buildings where sophisticated hvac systems must maintain critical environments.
Commissioning offers the opportunity to integrate and fine-tune all of the building systems to get the most efficient operation for the entire facility. However, the commissioning process is only as good as the tools that are used in the process. The reliability of the meters, gauges, and sensors used to validate the hvac system directly determines the effectiveness of the commissioning process. With appropriate design, setup, and validation, the bas is a valuable tool in the overall building commissioning process. Significant improvements in building efficiencies can be achieved along with better control of the building environment and fewer complaints from the building occupants.
