LEED Certificate for our Office Building

Since 2010 the Werner & Mertz office building has been a prominent landmark in Rheinallee in Mainz. The headquarters, crowned by striking wind turbine rotors on the roof, meets the highest international standards for sustainable and environmentally friendly construction. In recognition of this achievement, Werner & Mertz was awarded the LEED Platinum, the most demanding sustainability certification for buildings, in 2012. The office building is Germany's only industrial headquarters in the highest LEED award class. LEED (Leadership in Environmental & Energy Design) is a classification system for top-quality ecological buildings.

Werner & Mertz headquarters:
highest international award for ecological building.

The building's unique energy concept is particularly impressive. By means of wind power, photovoltaic cells and geothermal groundwater usage, the new building creates 20 percent more energy than required for its current operation. Furthermore, solar panels on the building's roof power two electric Smarts in the company's fleet.

The company's own well water supplies the heating/cooling system. From there the water flows into the new deionization plant on our production site and then into production for a resource-friendly second use.

The LEED certification system was developed in the USA by the non-profit organization U.S. Green Building Council (USGBC). The five environmental categories in a building’s rating are sustainable site, water efficiency, energy and atmosphere, materials and resources and indoor environmental quality, along with a sixth category called "innovation in design". The assessment is based on a fixed point system with platinum the highest of four quality levels.
