KBH Baustoffwerke Gebhart und Söhne GmbH und Co. KG, whose head office is in Lachen in the Allgaeu, Germany, has realised that a rethink is necessary in dealing with fossil energy sources. In order to keep stocks of concrete paving stones dry and to enable direct further processing, KBH has developed an innovative concept for stock-keeping. The new field of business KBH Solar has developed out of the idea of combining shelters with photovoltaic plants.
