Success Story Loxone Campus, Austria

Smart buildings require intelligent automation solutions that seamlessly integrate field devices. For this reason, Belimo has been working together with manufacturers of building automation solutions for many decades and supporting customers in the efficient implementation of their projects, including Loxone.

The cooperation with Loxone in the area of bus integration initially started with Modbus: Belimo created a Modbus library for the Belimo field devices. Loxone customers can use the corresponding templates unchanged or adapt them to specific projects. Later on, Loxone decided to implement the MP-Bus system, which supports the widest range of Belimo devices, allowing comprehensive flexibility in every project.

With Belimo Tree & Air, Loxone has created a gateway for both Loxone Tree and Loxone Air. Belimo supported Loxone throughout the entire implementation. The MP integration solution has also been implemented in the Loxone Campus and can therefore be put through its paces and optimised on an ongoing basis.

The MP-Bus® from Belimo was specially developed as a master/slave system for HVAC actuators. It allows up to eight different final control elements to be grouped together and connected to any higher-level system. 16 devices can be connected if only actuators of the latest design (e.g. ..-MPL) are used. Gateways and DDC controllers with an integrated MP interface serve as MP clients. There are no restrictions with respect to network topology. E.g. star, ring, line or mixed shapes are permissible.
 

The MP-Bus® uses a single installation cable, combining supply and communication in just three wires. It is very resistant to external interferences and requires no bus terminals.

Loxone expert Johannes Bartnitzke and Andreas Marty, Head of Product Management EMEA at Belimo, will tell you all about the Belimo MP-Bus technology and its simple and rapid integration into Loxone home and building automation.
 

The Loxone Campus combines numerous fields of application in a single building complex. Intelligent building automation can be experienced first-hand in various scenarios.

The offices on the Loxone Campus cover 3,000 m² and provide space for a total of 300 employees. Open-plan spaces with fixed workstations are complemented by bookable meeting rooms, soundproof phone booths, a lounge area and terraces for relaxation.

Pressure-independent characterised control valves from Belimo enable comfortable and energy-efficient heating and cooling of the offices using underfloor heating and cooling.
 

The design hotel on the Loxone Campus has 80 rooms and two suites. In addition, a 500 m² wellness area was built, which features an outdoor pool, two saunas, a gym and sunbathing areas.

Heating and cooling of the rooms takes place as required with ceiling induction devices. For these electronically pressure-independent 6-way control valves from Belimo were used, which ensure energy-efficient and reliable operation. The required energy is supplied as required, depending on occupancy and air quality.
 

The in-house restaurant is used all day by external guests, seminar participants and Loxone employees and can seat up to 600 people. If required, the restaurant can be connected to the adjoining auditorium using openable doors.

The air is fed into the restaurant and extracted in the kitchen. Pressure sensors from Belimo ensure that odours from the kitchen cannot overflow into the dining area or auditorium.
 

The auditorium of the Loxone Campus can be used for larger events, offering space for up to 600 people. The spacious hall can be used for concerts, events or lectures. In addition to featuring activities, it can also be used as part of the general catering facilities.

The auditorium is supplied by its own ventilation system, which feeds air underneath the grandstand. When the auditorium is connected to the restaurant, pressure sensors from Belimo enable optimum interaction between the ventilation systems in the two rooms.
