Commerzbank Tower
The architect and his client worked together to make the Commerzbank tower innovatively environmentally- and climate-friendly. Natural ventilation and environmentally-friendly air conditioning create a long-term contribution to climate protection. The tower has been supplied entirely with "green" electricity since the beginning of 2008 and - like all Commerzbank buildings - is cleaned exclusively with biodegradable cleaning products. In 2009 the city of Frankfurt awarded the Commerzbank tower the "Green Building Frankfurt" award.
