A leading US insurance carrier commissioned EES to replace a building management system for an existing headquarters and core computer facility. The system was designed to run efficiently and minimize critical downtime. The system also needed to provide the operators with the tools to effectively manage energy use while maintaining cooling using mixed fuel chillers.
The facility is an existing 37 story office building covering one city block in New York City. The owner wanted a seamless solution that would utilize the integrated industrial hardware for controls of the major HVAC systems with DDC based controls for office space requirements. The owner required that the system replace the existing JCI Metasys and JC80 control systems installed in the facility. The facility consisted of the following:
We worked with the owner on a design-build basis to provide a turnkey solution. The first step was to reverse engineer the existing JCI BMS, as documentation was limited or un-obtainable. After gaining a full understanding of the intended functionality of the existing BMS system, we examined the mechanical operation of the space and engineered solutions to meet the critical operational requirements for the systems. We provided full documentation and commissioned the BMS system and the HMI. Where applicable, we re-utilized existing cabinets, instruments, wiring and interfaces to minimize cost and impact to the day-to-day operations. Characteristics of the new control system:
The facility was retro-fitted in an efficient manner thereby minimizing the lost time to client activities. With the replacement of the existing commercial controls with a fully commissioned and documented BMS, operational staff have become more efficient on maintaining the system. This contributed to their overall bottom line. During performance of the project, the client commissioned Engineered Energy Solutions to retrofit two additional critical facilities utilizing similar technologies and goals.
