Introduction

The Deutsche Bank Twin Towers, also known as Deutsche Bank Headquarters (German: Zwillingstürme der Deutschen Bank or Hauptverwaltung Deutsche Bank AG), are two twin towers located in the Westend-Süd&action=edit&redlink=1 "Westend-Süd (Frankfurt am Main) (not yet redacted)" district of Frankfurt, Germany. Both towers have a height of 155 m and are the headquarters of Deutsche Bank, Germany's largest bank. The twin towers are sometimes nicknamed “debit and credit” (German: Soll und Haben), the two aspects of every financial transaction.

Location

The twin towers of Deutsche Bank are located on the border of the districts of Westend-Süd&action=edit&redlink=1 "Westend-Süd (Frankfurt am Main) (not yet drafted)"), Bahnhofsviertel "Bahnhofsviertel (Frankfurt am Main)") and Innenstadt&action=edit&redlink=1 "Innenstadt (Frankfurt am Main) (not yet redacted)"), close to a series of parks (Wallanlagen) and the Opernplatz. This area constitutes the financial district of Frankfurt, called Bankenviertel.

These towers are part of a group of skyscrapers located on Mainzer Landstraße, which extends from Opernplatz to Platz der Republik in the west. The towers have direct access to the underground Taunusanlage S-Bahn station. In front of the entrance there is a 66-ton monolith, called "Continuity", carved by the Swiss sculptor Max Bill.[6].

Architecture

The towers were built between 1979 and 1984, originally to house a Hyatt Hotel Group hotel. The buildings were already under construction when Hyatt canceled its project and Deutsche Bank decided to establish its headquarters there.

The complex is made up of three parts: a four-story base and the two towers. The buildings have a reinforced concrete structure with a glass façade.

In contrast to the nearby Trianon skyscraper "Trianon (Frankfurt am Main)"), built a few years later, the pedestal of the Deutsche Bank towers adapts to the urban environment. It is lower than the neighboring buildings, but has a larger surface area. They have an irregular plan with sections towards the east, southwest and northwest. Both have identical irregular trapezoidal floor plans that are symmetrical about a 45-degree angle.

Renewal

In 2006 Deutsche Bank decided that the towers would have to be renovated after 22 years due to changes in fire regulations. The renovation was carried out between 2007 and 2011. Not only were the fire protection systems improved, but all climate, plumbing and lighting systems were also replaced. This reduced the building's energy consumption and CO emissions by more than 50 percent. New glazing with opening windows further improved the energy balance. The goal was for the building to achieve the American LEED ecological certification with the highest category, platinum, and the German DGNB quality seal. The towers were the first skyscrapers to achieve this certification from the US Green Building Council. For the interior, the bank chose the Milanese architect Mario Bellini. During the renovation, around 2,500 employees moved to three other locations in Frankfurt, including the Investment Banking Center"), near the fair.

After a three-year renovation, the Deutsche Bank towers officially reopened on February 14, 2011 in a ceremony attended by figures from politics, business and society. Almost 26 years earlier, in February 1985, the building opened for the first time. Since then, the towers have become landmarks of Frankfurt and symbols of Germany as a financial center. Dr. Josef Ackermann, Chairman of the Board of Management of Deutsche Bank AG, explained: "These towers are not only landmarks of Frankfurt, they are also marks of a Deutsche Bank that is strong, socially conscious and globally oriented but has roots in Frankfurt and Germany. These towers represent, in the truest sense of the word, Deutsche Bank. We are truly at home here." Prof. Mario Bellini, designer and architect from Milan said that “the towers are symbols of a very solid company that has grown over many years, one built on solid foundations but at the same time remains very dynamic.”.

Deutsche Bank used the renovation of the towers to implement many innovative ideas, mainly in the field of ecology. The bank has reduced energy consumption by half, water consumption by more than 70 percent and CO emissions by almost 90 percent, making the towers one of the greenest skyscrapers in the world.

The towers received the highest certifications of LEED Platinum and DGNB Gold for their energy and resource use efficiency. Scot Horst (from the US Green Building Council) and Professor Manfred Hegger (from the German Sustainable Buildings Council) presented the two certificates to Hermann-Josef Lamberti who, as head of operations, was the member of the Deutsche Bank Board of Directors responsible for the renovation. Petra Roth, mayor of the city of Frankfurt, highlighted in her welcoming remarks the importance of green and sustainable buildings in urban development. "We are very pleased that the modernization of the Deutsche Bank towers has attracted global interest. Frankfurt deserves the reputation as a 'green city' in many ways. It is a goal we have been working towards for many years, and which we have further highlighted by applying for the European Green Capital Award 2014."
