The Key to Greater Efficiency

Integrative building concepts: Lanfer Automation unifies the varying systems of individual building technology sectors via the WAGO I/O System 750.

Smart buildings significantly reduce energy consumption. Thus, it is truly smart for all the technical components to be intelligently networked. Lanfer Automation GmbH, based in Borken, Germany accomplishes this using WAGO Controllers. The result is not just energy savings, it also opens up energy synergies.

Alfred Lanfer scans a QR code on a conference room’s door with his smartphone in order to prepare for the next meeting. With just one finger swipe on a tiny screen, the blinds lower, the lights dim and a projector and screen descend from the ceiling. “This is the presentation function that we were able to create with just one switch by using EnOcean technology,” explains the CEO of Lanfer Automation GmbH. This small, concerted display of technical finesse is just one piece of what the project developer, located in the Westphalian town of Borken, can do. The company completely renovated its headquarters in late 2013, in which the building was equipped with innovative automation technology – from cellar to ceiling – and targeted energy efficiency. It would be easy to view the entire office building as one big showroom. “Technologically, a lot more can be done today than is conventionally implemented,” explains Lanfer. And the company from Borken wants to demonstrate just what can be done. However, the building does not just reflect the visionary philosophy that led to the company’s founding in 1979; the project also reveals a groundbreaking change in the design and networking of technical systems.

Another finger gesture on the smartphone allows Lanfer to reset the conference room to its original configuration. “The demands placed on buildings and individual rooms naturally vary quite a bit,” he says. “The basic idea is to accommodate multiple demands under one roof. It can’t be too warm or too cold, the light has to be right; at the same time, everything must be as energy efficient as possible. The key to this is automation. Moreover, the individual intelligent components cannot be intelligent islands.

It is really smart and efficient when they are networked.” This type of integrative application has been a focus of sector experts for a long time, as the potential for additional energy savings is high. While energy efficiency is an important factor in real estate, according to Lanfer, these types of projects are uncommon. “Only a few design companies are currently pursuing integrative concepts in which the individual building systems are synchronized with each other.”

Whether it’s heaters, air-conditioning technology or illumination, Lanfer says each system presents good opportunities for adding intelligence to buildings and for using energy as efficiently as possible. However, since these individual building systems in their traditional forms do not have overlapping technology or combined installations, the end result is not always the optimal. “A typical example is when the heating and cooling systems work against each other. It is too warm, so the air-conditioning system automatically switches on; however, the heating does not switch off at the same time,” explains Lanfer. An integrated concept would prevent this. In this case, the advantages extend well beyond additional energy savings. Synergistic effects also came from the installations themselves; for example, bus technology alleviated the need for laying multiple cables. Lanfer Automation achieves additional savings by using the flexible WINSTA^® Pluggable Connection System from WAGO, which simplifies connections between systems and devices.
