Migros Westside Berne – unique in the World.
With the latest energy-saving technology, controlled by Saia®PCD3


On 8th October 2008 the largest shopping and lifestyle centre in Switzerland, at the gateway to Berne, opened its doors to the public. This architectural masterpiece by the star architect Daniel Liebeskind does not just impress with its timeless design, but is also a unique concept for shopping, entertainment, wellness, and community living on a scale very rare in Switzerland.

During the planning of Westside, aspects considered were not only economic, but also ecological. The planners of Migros Westside took on responsibility for the environment and built the project according to the “minergie” standard. This means that 20 percent of energy need is covered by renewable sources. Only 15 percent of Westside’s annual heating requirement is met with fuel oil, 35 percent with heat recovery, and around 50 percent with a modern wood-chip heating system.

For implementation of Westside’s technology, products from Saia-Burgess Controls Ltd were chosen as the control components. This was because of the great flexibility of their hardware and software, and the ideal interaction between three Swiss system integrators. In order to meet strict deadlines, the lead contractor in the fields of electrical engineering, measurement, control and automation, Burkhalter Technics AG, decided to appoint two additional companies to share the assembly, project planning, electrical design and execution.

The dimensions of such a mega project demand, in every regard, extraordinary hardware performance and seamless integration. Thanks to outstanding cooperation between the three Saia-Burgess Controls system integrators, this multi-layered project was completed on time, ready for the clients to move in and start operations.

Teamwork around Saia®PCD
System integration was achieved by a strong team: “use it”. This was a collaboration project between three of the top Saia® integrators in Switzerland: MST, Burkhalter, and Renergy.
Control, display and visualization components from Saia-Burgess Controls cover the entire spectrum offered. Using Saia®PCD3 for basic control in the measurement, control and automation fields, all main and substations for heating, ventilation and air-conditioning are connected together via ethernet. The different user zones are monitored and controlled by a total of five independent Visi.Plus management systems with an overall data-point volume of 12 000 DP. Connection between individual project zones is ensured by fast, optical fibre router connections.
On-site operation is via 10” CE Web-Panels, available to the operator in each of the larger air-conditioning control centres.
The 144 rooms of the Holiday Inn (incl. seminar rooms) are equipped with fan-coil circulating air conditioners. Each room has a PCD7.L601 controller and a PCD7.L643 digital room control unit with display to provide the desired level of comfort.
Integrated into a network of PCD systems with TCP/IP communication via ethernet and optical fibres, all operating states are permanently on-call from Web-Panels using a comprehensive SCADA system.
