Exemplary new building

Since 2010 the Werner & Mertz headquarters has been the striking landmark in the Rheinallee in Mainz. The building, crowned by striking wind turbine rotors on the roof, meets the highest international standards for sustainable and environmentally friendly construction. In 2012 Werner & Mertz received the "LEED Platinum", the most demanding sustainability certification for buildings. This makes the new structure Germany's only headquarters of an industrial company in this highest award category.

LEED stands for Leadership in Energy & Environmental Design and classifies high quality ecological buildings. The LEED certification system was developed in the USA by the non-profit organisation USGBC (US Green Building Council).


Above all the energy concept is impressive: using wind power, a photovoltaic system and the exploitation of geothermal groundwater the new building generates 20 per cent more energy than it needs for ongoing operation. Solar power from the roof of the administrative building is used to charge two electric Smarts as company cars.

The heating and cooling system is supplied with our own well water, which is then desalinated and used a second time in production, thus conserving resources. Even before its official inauguration the new head office received the prestigious Rhineland-Palatinate Environmental Award in June 2010. The building is a highly visible sign that Werner & Mertz itself consistently practises sustainability.
