Facility managers locked into proprietary controls software know the pain and reality of trying to efficiently manage their controls system when there are few to no options. It is expensive—limits choice in controls vendors and software; it is inflexible—won’t easily support future additions and upgrades; and it is frustrating—giving a vendor business because you must, not because earned value has been demonstrated. A controls integration based on an openly-licensed front-end will resolve this problem and serve the system well into the future. Integrating the existing controls from different manufacturers—such as Barber-Colman, Trane, Johnson Controls, Carrier, and Siemens–into one centralized building management system offers the ultimate in efficiency, flexibility and cost savings.
