The new building features modern, open architecture

Industry Solution Center Bad Pyrmont

Building 4 comprises 18,000 square meters and features modern architecture with a lot of glass and a large atrium that spans all floors.

The building’s open character is also reflected in its infrastructure, the room automation, and the flexibly designed working areas.

Efficient energy management and optimized supply processes

Efficient energy management and an optimum supply process have been achieved through the intelligent networking of power generation, energy consumption, and energy storage in combination with the heating and cooling circuit. The four office and production buildings at the site are supplied with energy via a ring concept, in which all generators, loads, and storage systems are interconnected.

Two combined heat and power plants cover around 60% of the auxiliary power consumption. The waste heat generated by these plants is used to heat and cool the buildings. The active load management uses a stored control strategy to ensure that peak loads are not exceeded. For this reason, the new Building 4 does not need its own separate supply.

Nearly all ventilation systems are equipped with heat recovery. With an output of 160 KWp, the photovoltaic system on the roof is also actively integrated into the electrical power supply system. The aim is to use this renewable energy for the charging stations for electric cars, among other things.

Connecting the building services management system with active energy management

When it came time to realize the building technology, the Facility Management team decided to use components and systems from Phoenix Contact’s own product range. It is based on the Emalytics building management system, which connects the building services management system to the active energy management system. The higher-level system receives the field level data from 27 ILC 2050 BI controllers. The Niagara framework-based controller acts as a smart device that standardizes all the data from the trades and transfers it to the Emalytics building services management system.

Both the classic sensor and actuator technology and the new, intelligent IP-based field devices can be quickly and easily integrated into the system. Based on the recorded information, Emalytics facilitates the predictive maintenance of the installed devices. For example, unusual data can alert the operator to future faults. Emalytics analyzes the characteristic values of the spark plugs of the motors installed in the combined heat and power plant and, if necessary, recommends preventive replacement. This significantly increases the runtime of the combined heat and power plants.

Location-independent control and monitoring of properties

Furthermore, the ILC 2050 BI supports all established building technology standards such as BACnet IP, BACnet MS/TP, M-Bus, KNX/TP, SNMP, and oBIX. Corresponding modules in the Inline I/O portfolio can be used to connect common bus systems such as DALI, Modbus/TCP, and Modbus/RTU. The protocol-independent integration of the field devices into the ILC 2050 BI controller greatly simplifies the engineering and cabling work involved.

The building management system makes it possible to easily control and monitor the various premises from any location. Moreover, existing buildings can be easily integrated into the new system. This provides numerous benefits for the operator, who can now compare locations or set up a communication platform for all premises. It is possible to improve the supply processes for all buildings based on the existing data, which results in more efficient management of the premises.


Rotermund Ingenieurgesellschaft mbH & Co. KG specializes in optimizing building operations, calculating lifecycle costs, and benchmarking the usage costs of buildings. The company carried out a competitive analysis for Phoenix Contact on the basis of a benchmark from a wide range of building types with a gross floor area of 85,000 square meters. The results demonstrated that the Bad Pyrmont site is at the lower end of the cost group. This was achieved through innovative concepts in the area of building infrastructure and technical and commercial building management, as well as efficient supply and disposal cost design.
