Automation Data as the Foundation for More Sustainable Buildings

Building Automation Drives Efficiency and Innovation

Are sustainability, the energy transition and climate protection essential components of your company’s philosophy? The Wilo Group, one of the world’s leading providers of premium pumps and pump systems, uses “green solutions for a better climate” to put this philosophy into action, and constantly proves it with its products. One ambitious construction project, the innovative Wilopark facility, is tackling these issues head-on and achieving these goals. Building automation plays a key role in this project.

The Wilo Group, global leader in pumps and pump systems for building technology, water resource management and industry, is combining its 150 years of tradition with a sustainable vision of the future: “We move water – intelligently, efficiently and in a climate-friendly way.” An impressive new concept is being implemented at the Wilopark construction site that spans 20 hectares in Dortmund: A modern innovation center. Consisting of a factory, management and production areas as well as a networking center for customer meetings, the facility is under construction here to more efficiently exploit synergies from different sectors. The goal is energy-efficient buildings, smart and lean production, energy generation from renewable sources and the implementation of digital processes to create added value for employees, customers and the environment. The implementation primarily requires sophisticated building automation: Hermes Systeme GmbH was selected to design and implement the ICA and automation technology, and WAGO system technology forms the foundation.

A Project Overview:

  • The requirements for building technology:
    Provide flexibility for individual areas and respond to future demands.

  • Future-oriented and sustainable:
    The project relies on digitally networked building technology.

  • Data means valuable (efficiency) knowledge in Wilopark:
    All data points must be individually and reliably controllable. 

  • Wilo and Hermes Systeme rely on WAGO’s modular I/O system to control the building automation.
    A total of 125 PFC200 Controllers are installed in Wilopark.

The Technical Building Equipment

The innovative Wilopark’s design presents a special challenge for building technology. The object was to configure the individual areas as flexibly as possible, thereby integrating the building equipment so that it can correctly react to all current and future demands. Particular emphasis was placed on area neutrality, flexibility and efficiency.

The enormous construction project is divided into multiple phases, with the majority slated for completion by company’s 150th anniversary in 2022.

Therefore, all lights, meters, presence sensors, volumetric flow controllers, pumps and shading systems in the new construction were integrated into the building management system (BMS). “In this project, we’re talking about a good 6,500 hardware data points and around 100,000 virtual data points,” reports Christian Nölker, Project Manager BMS at Hermes Systeme GmbH. The company has specialized in automation and industrial wiring projects for 30 years, and was entrusted with managing the HVAC work, boilers and air-conditioning controllers as well as lighting and blinds in the Wilopark project. Markus Kauling, who is responsible for Wilo’s supply technology and energy supply, explains the goals for the building automation, “We want to view everything at once, and have the necessary access to all operating and diagnostic data from the data points. They also must be controllable because every data point generates valuable information for us.”

Building Automation in a Key Role

Another important aspect of the building automation system lies in systematic maintenance management. The operating and diagnostic data generated from the data points can be output as error messages by the higher-level control system. Due to these networked error messages, the building technology can ensure consistently high quality for the workspaces and air conditioning and do it with much greater efficiency.

“In order to reliably and consistently provide all of the data, we rely on a completely integrated automation solution and object-oriented programming,” explains Nölker, the project leader from Hermes. “Our customers expect reliability, and we expect the same from the hardware we install. This is one of the main reasons that we decided on WAGO.” The entire control level at Wilopark is implemented using WAGO products. Hermes has integrated a total of 125 PFC200 Controllers from the WAGO I/O System. “The variety of supported protocols is the second aspect, which clearly and directly pointed toward controllers from WAGO,” adds Nölker. In this way, the hardware has overcome one of the greatest challenges in the pump manufacturer’s BMS: the sensors and actuators can be linked to the controller using a good dozen different interfaces, like Modbus TCP, Modbus RTU, or BACnet®, which provides a high degree of flexibility.

Wilo and Hermes Systeme rely on WAGO’s modular I/O System to control the building automation: a total of 125 PFC200 Controllers are installed at Wilopark. The flexible system provides ample space for future expansions.
