Automation At ADAC; Integrated Approach, High Efficiency

Integrated automation solutions ensure high energy efficiency at the ADAC center.

The demands on automation systems for modern office buildings are correspondingly high. In the ideal situation, building automation should include all trades and systems. This type of integrated solution enables easy operation, flexibility in use of spaces, and high energy efficiency for the user as well as for technical personnel. When setting up the new association headquarters in Munich, ADAC selected building automation components and systems from WAGO for this very reason.

With more than 19 million members, ADAC is the largest automobile club in Europe, and the second largest in the world. ADAC currently has around 6800 employees, and more than one-third of them work in the new center in Munich. The building, located on Hansastraße, was purchased in 2012 by the workers in Munich, who were previously scattered across the city at various locations. The association headquarters, designed by the Berlin architectural firm Sauerbruch Hutton, consists of a skyscraper, which at 23 stories and 93 meters can be seen from afar, and a structural base with an additional five stories. The distinctive structure and the configuration of the exterior in the yellow shades long identified with ADAC add eye-catching qualities to the building.

Flexibility and Energy Efficiency

ADAC placed special emphasis on energy efficiency. Various solutions were ultimately integrated into one total concept in order to achieve the lowest possible energy consumption. Structurally, for example, a double glass facade was incorporated, with a shade installed between the inner and outer facades. This positively supports the lighting, heating, ventilation, and air conditioning systems. Another important aspect for conserving energy is the use of shallowground geothermal energy, which can cover one-fourth of the heating required at the ADAC building. During the summer months, the geothermal system supports building cooling. A thermal concrete core activation has been ideally combined with the this system.

Modern Automation Technology

In order to operate all building systems in an energy efficient way, modern automation and suitable building control technology were necessary, in addition to the corresponding generators, devices, and installations, such as blinds, lighting, and HVAC systems. AT ADAC, they selected the expertise and technology from Minden for their building automation. “We had already had good experiences with WAGO at our old location in Munich,” explains Markus Lamers, who is responsible for building automation in the building services department at ADAC. “Above all, we didn’t want a proprietary system, but an open one.” This helps to explain their selection of controllers and suitable modules from the WAGO-I/O-SYSTEM, which can be accommodated in a system housing, together with a mains adaptor, and which can be easily connected using pluggable connections. Each of these system distribution boxes takes control of the heating, ventilation, air conditioning, shading, and lighting systems along one of eight axes of ADAC’s office building in Munich.

In order to optimally adapt to the external environmental conditions, an additional controller is linked to the weather station installed on the building’s roof. This enables the transmission of current data, like outside temperature and direct sunlight, to the system distribution boxes and the connected primary systems. Due to the unusual shape of the building, the control of the shades as a function of solar position and direct sunlight is divided into eight regions. This allows the system distribution boxes from WAGO to ensure that no rooms get too hot in the summer. In the winter, in contrast, sunlight can be used to support the heating systems during clement weather.

Energy efficiency is also a component in the lighting of the ADAC building: in general, downlighting is installed that can be adjusted to the corresponding environmental conditions. Naturally, the level of direct sunlight and the time of day play important roles. An additional LED floor lamp is available at each workstation in the office areas, providing optimal illumination for ergonomic comfort. These lamps combine indirect ceiling illumination with lights that are focused directly on the desks. Presence detectors in the floor lamps ensure that the workstation illumination is only on if someone is actually at the desk. All lights are controlled from the control center and system distribution boxes via DALI buses. At 10 pm, the building control technology sends a shutoff command to all lights in the work areas. Should an employee forgot to turn off his or her light, then the building automation ensures that electricity is not squandered overnight.

Automation for Flexible Use of Spaces

An essential specification during planning, in addition to the high energy-efficiency requirements, was to ensure that the building spaces could be easily adapted to a variety of uses. In order to react quickly to changing needs, floor areas should be easy to rededicate. The electrical wiring is therefore standardized and also flexibly executed. “We equipped almost all of the switches for lights and blinds with the EnOcean wireless standard,” explains Lamers. This allows switches to be easily allocated to another use, without requiring work on the electrical system. EnOcean communication uses corresponding interfaces in the WAGO-I/O-SYSTEM.

The electrical wiring itself was designed to be highly flexible. The floor boxes that supply the workstations and floor lamps were equipped with the WINSTA® pluggable connection system for this reason. “A pluggable solution like WINSTA®,” Lamers continues, “makes it very asy to implement changes to the electrical wiring as they become necessary. At the same time, we saved a lot of time on the wiring and start up for the building automation by using WINSTA®.” In addition to power supply cables, WINSTA® also includes light control cables via DALI.

Over 40,000 Data Points are Connected to the Building Control Technology

ADAC employs an autonomous network within the building for its automation technology, which is completely separated from the IT infrastructure. All automation systems are connected to the control technology using Modbus/TCP on this total building automation (TBA) network. More than 900 WAGO controllers are in use: they are installed within office spaces for control tasks, and are among the components used in the building control center. Lamers explains, “The great advantage in using the WAGO-I/O-SYSTEM is that a suitable interface card for almost every automation task already exists.” In addition to DALI and EnOcean, M-Bus and KNX interfaces, as well as digital/analog inputs and outputs are deployed throughout the ADAC building. In total, more than 40,000 data points are connected to the building control technology.

Open System with High Reliability

In the meantime, the wiring and startup of the automation systems has been concluded, and everything works just the way ADAC wanted. The open system, which can be easily programmed, and the high standardization, achieved using system distribution boxes and WINSTA® electrical wiring, made substantial contributions to the project’s success. If any component should fail, the replacement of individual interface cards or even complete controllers is quite easy. “That hasn’t been necessary yet,” states Lamers; the quality of WAGO components and systems have demonstrated themselves once again.


  • WAGO system distribution boxes take on the control of technical systems, heating, air conditioning, ventilation, shading, and lighting.
  • The integrated automation solution using WAGO technology ensures high energy efficiency, flexibility, and user comfort.
  • Pluggable cabling using WINSTA® optimizes electrical wiring with regard to time, costs, and flexibility.
