Schneider Electric Norway leveraged the experience they gained on a previous project to win an energy performance contracting project for the public buildings, schools, and nursing homes within the Orkdal municipality. A primary requirement was to deliver a uniform Building Management System for all the public buildings in the municipality.
Much of the project involved delivering BACnet technology through SmartStruxure to greenfield buildings. Two of the municipality’s buildings contained legacy JCI Metasys® systems and were included in this project phase. The project scope involved heating zone control- and ventilation systems at Orkdal nursery, and heating and zone control at Rianmyra Kinderkarten. A project requirement was to bring these two buildings into the single seat uniform user interface implemented for the entire municipality. This streamlined operations, training, and support of all buildings which, in turn, gave them energy savings. BACnet standards and the S4 technology made this possible.
Enterprise Level Automation was provided by a Schneider Electric StruxureWare Enterprise Server. Building level automation was provided by Schneider Electric StruxureWare Automation Servers at each location. The savings are measured in an Energy Operation system from Schneider Electric that was included as part of the technology upgrades delivered to the municipality.
During the building assessment and planning process the Schneider Electric team determined that the existing Metasys® field controllers (DX-9100s and FX07s) were still performing well and probably could for the foreseeable future. The selection of the S4 Router allowed the integration team to extend the useful life of, and enhance the services provided by, the existing devices.
The building operator wanted to completely replace the Metasys® user interface, and did not require a transition period of coexistence with the legacy Metasys® head end system. In addition, the small amount of time required to perform the integration would not adversely affect the comfort of building occupants. Therefore, the decision was made to not utilize the unique ability of the S4 Open: BACnet-N2 Router to enable the coexistence of the legacy Metasys® head end and the SmartStruxure Automation Servers on this project.
Instead, one of the integration tasks was to move all scheduling, global variable support, and other services and functions of the Metasys® NCM supervisory controller to the Schneider Electric Automation Server in each building. Because most of the legacy Metasys® N2 controllers were application specific devices they continued working with last known good values of global variables minimizing the impact on building occupants during this transition.
The Configure Wizard built into the S4 Open Management Console (the user interface for the S4 Open: BACnet-N2 Router) led the Schneider Electric team through the integration process, accurately discovered the N2 devices, and assigned the appropriate S4 device templates that provided BACnet point mapping for application specific controllers. When the Configure Wizard completed its task, the discovered N2 devices were automatically published as BACnet devices under a virtual BACnet network. The DX-9100 systems are a special case. Each is custom programmed and has a unique point map. The Schneider Electric team used the S4 Open Metasys® Configuration File Conversion Utility to generate custom Device Templates exactly matching the point assignments for each DX-9100. The integration team then assigned the custom Device Template to the device object in the BACnet-N2 Router for each DX-9100.
The legacy Metasys® field devices will continue to serve these buildings well into the future. This is a testament to the design and manufacturing quality that JCI put into these devices. But all electronic devices have a finite lifetime no matter how good they were on day one. So a short term plan is included to replace these devices if any fail prior to a major building renovation being scheduled.

Number of Buildings: 2 Total Area: 53,270 sq ft.

Special Features:
Outcomes were measured through interviews with the client after the integration of these two buildings was completed and the user interface was provided via Schneider Electric’s SmartStruxure. The building operators observed that they can operate their installations in an easier way than with the legacy system and, as a result, use less time for inspection. The goal of a single, uniform building management system for all buildings in the municipality has been achieved, creating less energy costs.
