Energy talk at VW

Grundfos showed auto maker how to lower life cycle costs

Volkswagen wants to save energy and carbon emissions -not only in the cars it produces, but in its factories, too.

The company's internal task force for energy and environment recently asked Grundfos to give a talk about life-cycle cost (LCC) analyses at a three-day workshop in Königslutter, Germany. Participants included all VW employees within environment and production from all VW European sites and Volkswagen brands (including Seat, Skoda and Audi).

Grundfos' Heinz Maier gave several examples in how to identify potential ways to save energy with pump audits and the Grundfos LCC Tool Box.

"After our discussion, the senior energy management at Volkswagen Wolfsburg agreed to further promote the necessity of pump audits and LCC analyses at European sites with Grundfos," Maier says.

VSD requirement
Saving energy is not new to Volkswagen, says Maier. "The internal Group Energy Task Force has been promoting such measures for years," he says. The task force works with production operators and companies in the VW supply chain to employ systems that optimise energy use.

"The central energy management is now going to a pass a resolution that only permits the use of frequency-controlled pump systems where there is variable production," Maier says. "Valves can no longer be used to control the flow rate in pumps." This requirement will be incorporated in the group works standard. Future tenders will also require variable-speed drives (VSDs) in worldwide bids.

VW also leverages its financial controlling system to exert pressure on its various sites to reduce costs in production by means of suitable energy-saving measures, Maier adds.
