About the Customer
The Four Seasons Hotel in Miami, Florida is a high end, mixed use, 70 story building that includes the Four Seasons Hotel, The Sports Club LA, and Class A Office Tower. The building has 221 luxury guest rooms and 84 condo hotel rooms. Floors 40 to 70 house its luxury residences.
Located in the heart of Miami , the Four Seasons Hotel, as one of the world renowned Four Seasons properties, is a luxury hotel that promises the customer an experience of exceptional comfort and service.
The customer wanted to update the older Johnson Controls System that was installed back when the building was constructed in 1992. Because the system no longer met with the building owners objectives they contracted with a third party firm to analyze the system, make recommendations as to what the new system should accomplish and to help with execution.
The building owner wanted each customer in the building to be comfortable. Whether an overnight guest in the hotel, luxury condo or living space resident, an office worker or a patron of the gym, everyone should be comfortable, with the building operating in an energy efficient and cost effective manner.
About the Project
South Florida Controls was awarded the contract for the new BCS. The initial approach was to do a full retrofit; however, due to the high replacement cost, and the operational impact to the Four Seasons business, the integration path was chosen and followed in the project.
The decision was made to partner with The S4 Group, Inc. The S4 Open: BACnet-N2 Router establishes a cost effective gateway from legacy Metasys® N2 to BACnet IP, quickly adding value and extending the life of legacy systems. The BACnet-N2 router was used as a gateway to the Delta Controls system which provided enhanced visualization, improved control sequences, and energy efficiency improvements. The BACnet-N2 Router acted as a BACnet server, the Delta Controls head end, ORCAview acted as a BACnet client, polling data from the S4 Open: BACnet-N2 Router.
Over the long term, the S4 Open Appliances facilitate the migration away from the legacy Metasys® N2 devices to a pure BACnet environment, without having to take the building out of service for a retrofit. The installation of the seven S4 Open:BACnet-N2 Routers allowed the project to salvage the N2 controllers and integrate the large (500+) number of VAV boxes, lighting controls, exhaust fans, and pressurization systems to Delta ORCAview. The critical central plant equipment was retrofitted to Delta Controls controllers to maximize their efficiency because of the heavy demand for cooling capacity year-round.
A large part of the plan called for the Johnson Controls NCMs to be kept online and functioning. The S4 Open: BACnet-N2 Router is the only technology that allows an integrator to meet this requirement. The Upstream N2 Interface of the BACnet-N2 Router enables the legacy NCMs and Metasys® Operator Workstation to co-exist with the new ORCAview head end. The integration of the legacy Metasys® N2 devices and the new Delta field devices was seamless to the owner and building operator. The end user was able to immediately pick up all his points on the front end and continue working on the system as though nothing ever happened. Since Delta Controls is 100% Native BACnet, the whole integration process went off “without a hitch”. The customer never experienced any downtime which was a major concern in a building with so many tenants, customers, hotel guests, & residents to attend to.
Project planning and preparation provided a major role in the success of the project. By using the Combus Quick Tester to validate the installation before starting the integration, the condition of the existing system was well understood. The customer was provided a list of what was working and what was offline; offline items were placed on the task list to be fixed as part of the project to ensure that required data was available for the new system. With a known and validated N2 bus and operational controllers and mechanical systems, the N2 devices and points were easy to discover and publish to BACnet using the S4 product.
During the integration process, the South Florida Controls team worked in an efficient manner to provide the building owner with the system design, technology, integration services, and training to create the outcomes they specified.
The project is now complete and the owner has verified the outcomes. Since the completion of the project, the building owners have experienced substantial increases in the comfort levels of their guests, residents, employees and tenants in spaces that were previously not properly controlled and either too cold, hot, or humid. Now the increased level of control and visualization has allowed them to track, monitor & adjust the building to optimize indoor air quality while increasing building efficiency.
The goal of having a fully functioning front end BMS has been achieved. The owner can now properly manage all the systems in the building and can see what is operational, non-operational, what needs to be fixed, looked at, etc
