Sustainable Like No Other: The toom Home Improvement Center in Nieder-Olm

Equipped with the WAGO I/O System 750, toom Baumarkt in Nieder-Olm, Rhineland-Palatinate was the first home improvement center in Germany to meet the “Silver” certification requirements of the German Sustainable Building Council (DGNB).

A paradise for both professionals and do-it-yourselfers: At toom, customers can find anything related to building and technology, as well as interior design and ambience. Toom’s garden centers also provide a seasonal assortment of plants for indoors, balconies and garden beds. For toom Baumarkt, a subsidiary of the REWE Group, being a responsible member of the community is a key part of their corporate philosophy. As part of their sustainability strategy, they are equipping new and existing buildings with WAGO’s automation technology. By 2015, the chain seeks to reduce the CO2 emissions for 360 German stores by 30 % per square meter of sales floor compared to 2006 emission levels.

With the opening of a new store in Nieder-Olm, Rhineland-Palatinate, toom took another step in the implementation of its sustainability campaign. This store, which was completed at the beginning of 2012, is the company’s first certified Green Building and was designed specifically to conserve energy and water during daily operations. Toom Baumarkt in Nieder-Olm was also the first home improvement center in Germany to meet the “Silver” certification requirements of Germany’s Sustainable Building Council (DGNB). “We made a conscious decision to get certified by the DGNB, because for us it represents the most sensible link between the environmental and economic aspects of quality,” explains Tobias Müller, who is in charge of energy management in toom’s properties.

Environmentally and Economically Sound

Müller was involved in ensuring that the REWE Group subsidiary can achieve its ambitious goal: Between 2006 and 2015, the CO2 emissions per square meter of sales floor should be reduced by 30 % – in all its stores, of which there are about 360. This can only succeed if heating energy and electricity are used efficiently. The REWE Group also promotes renewable energies, and all toom home improvement centers are powered exclusively with renewable electricity. The Green Building in Nieder-Olm, Rhineland-Palatinate already supports the active reduction of greenhouse gas emissions with additional environmentally friendly technologies for obtaining energy, as well as construction elements like daylight-harnessing architecture and efficient insulation.

The automation side of things also went through a significant technological change. “Up until then, we mostly had proprietary systems installed in our stores, which meant we were quite dependent on the manufacturers – and there were a lot of them. We’ve now addressed that issue by switching over to the CODESYS programming environment and the WAGO I/O-SYSTEM across the board,” says the engineer. The sales center in Nieder-Olm covers just under 9,000 square meters and includes a total of nine WAGO 750-880 ETHERNET Controllers installed in decentralized control cabinets. J&K Lausser Regeltechnik of Starnberg, Bavaria handled the implementation. Use of a uniform automation system for instrumentation, control and automation, as well as for the electrical systems, made the data communication much simpler. This eliminated the need for special interfaces, which are otherwise the norm.
