The towers received the highest possible certifications of LEED Platinum and DGNB Gold for their resource and energy efficiency. Scot Horst (U.S. Green Building Council) and Professor Manfred Hegger (German Sustainable Building Council) presented the two certificates to Hermann-Josef Lamberti who, as Chief Operating Officer, was the Deutsche Bank Management Board member responsible for the renovation. Petra Roth, Mayor of the City of Frankfurt am Main, emphasized in her welcoming remarks the importance of green and sustainable buildings in urban development. “We are delighted that the modernization of the Deutsche Bank towers has attracted interest worldwide. Frankfurt deserves its reputation as a 'green city' in many ways. This is a goal that we have been working towards for many years, and one that we have further highlighted by applying for the 2014 European Green Capital Award.”
