The new building for the Minden Campus of Bielefeld Technical College is a pioneering project for two reasons: It integrates cutting-edge energy and automation technology, and is also a prime example of cross-discipline, integrated construction. Due to close collaboration, the designers and building trades reached a precise target in quality and costs.

Old works of art require a stable room climate. To optimally maintain them, the correct temperature and humidity must be fastidiously observed. This applies in particular when temporary exhibits are displayed with loaned pieces, because no one will provide art works if they are not assured that they will be returned in the original state. Therefore, in the course of substantial modernization work at the Oldenburg Augusteum, an indoor air system including individual room monitoring was installed, controlled using the WAGO-I/O-SYSTEM 750. This automated solution guarantees optimal conditions and additionally helps with energy savings. Narrow spatial relationships and monument protection requirements provided challenges for the planners.

The Hotel Meliá Castilla is considered one of the most beautiful hotels in Madrid. It combines classical style and modern amenities into an ambiance of quiet and relaxation, in the center of the Spanish capitol city. In order that the hotel, with its favorable location, remains successful in the future, the international Meliá Group constantly works to connect service and comfort with efficiency and sustainability. Recently, the Spanish system integrator ALTARE Energía completed a modernization program for the heating system, together with WAGO.

Heat pumps for heating or cooling buildings usually draw their energy from geothermal probes or earth collectors. The building technology company leitec® took a different path: an ice energy store provides the necessary energy. WAGO technology controls the interplay between the system and the entire building automation.

The term ‘sustainability’ is often used excessively; however, the Kreissparkasse [district savings bank] in Göppingen has impressively revitalized it over the course of their construction project. The environment, employees, and customers all profit from the results of the new construction plus renovation, which combine energy efficiency with comfort. The German Sustainable Building Council (DGNB) awarded the new construction with a gold medal for systematic execution of a green building design. The renovated building, constructed in 1974, received silver. In addition to design and architecture, the intelligent climate-control technology, using state of the art WAGO controllers, is a key component in the dapper building complex. One novelty is the comprehensive academic support for the optimized, energy-efficient construction.

With the advent of spectacular live concert events, sports arenas in large cities and metropolitan areas have developed into multifunctional buildings that can do much more than house soccer or track and field competitions. The VELTINS Arena in Gelsenkirchen is typical: official Bundesliga stadium, stage for concerts and operas, and site of biathlon competitions. The versatility places correspondingly high demands on the building automation, both functionally and in terms of availability. Therefore, the stadium in Gelsenkirchen was modernized, replacing the 15-year-old centralized building control system with a composite network using WAGO controllers. The architecture can act as a precedent for lean and powerful Industry 4.0 solutions.

In heating, ventilation and air-conditioning applications, it is common for individual units to be switched on or off independently of the control program. A typical example is a pump that must be temporarily switched off for maintenance. WAGO offers the 2852 Series Manual Control Units for this purpose. The devices are installed in the control cabinet door, which allows them to be operated without opening the cabinet door. Controller connection is established via Modbus RTU.

A building’s technological systems form an important foundation for the energy-efficient operation of real estate. Planning and execution must be correspondingly accurate and professionally implemented, particularly for heating, ventilation, and air-conditioning systems. In this context, WAGO offers not only suitable products and solutions for automation technology, but also supports the systems engineering process with application instructions and macros.

The building services provider, Wisag, replaced an old, proprietary building automation system in the Steag control center with a modern one that is not tied to a specific manufacturer. The new system uses I/O controllers from WAGO as key elements. It integrates multiple, previously decentralized technical islands and substantially facilitates building management.

Already a matter of fact in the private domain: apps have become an indispensable and practical tool in our everyday lives. Now, WAGO demonstrates with its WebVisu app the benefits that this application software brings to mobile devices and building automation — automated systems can now be conveniently operated and monitored from mobile devices.

The Bielefeld University of Applied Sciences and NRW, a property management and construction company (BLB NRW), charted a new path in the construction of the University of Applied Sciences building on the Minden Campus of Bielefeld Technical College in Bielefeld, Germany. It integrates cutting-edge energy and automation technology and is a prime example of crossdiscipline, integrated construction.

The variety of building systems with their different communication standards is a growing challenge in building automation. The current trend provides a protocol for all levels. The BACnet transmission standard, which is well-established at the building automation level, also provides seamless integration from the control level to the field level.
