Post Tower Wins CTBUH 10-Year Award

Post Tower, a 163-meter office tower in Bonn, Germany, has received the 10 Year Award from the Council on Tall Buildings and Urban Habitat (CTBUH).

The 10 Year Award recognizes proven value and performance in a tall building, across one or more of a wide range of criteria, over a period of 10 years since its completion. This award gives an opportunity to reflect back on buildings that have been completed and operational for at least a decade, and acknowledge those projects which have performed successfully, long after the ribbon-cutting ceremonies have passed.

Completed in 2002, the Post Tower blazed new trails by using technically integrated design to deliver high performance. Its two elliptical volumes, with an atrium between, work together with site and wind orientation, a double-skin, operable façade, and stack ventilation to remove much of the need for mechanical ventilation commonly found in large buildings. This not only allows the building to consume only 75 kilowatt-hours per square meter per year, which is 79 percent less energy than a typical office building of its size; it also makes for pleasant interior sky garden spaces and a more efficient floor plate.

“The Post Tower was an early touchstone for sustainable tower design and has provided a very useful model through its attention to performance,” said Awards Jury Chair Jeanne Gang, founding principal, Studio Gang Architects. “The jury was impressed with the continued monitoring and proof of concept.”

“The Post Tower undoubtedly changes the way we look at sustainable building for the high rise typology,” said Awards juror David Gianotten, managing director, Office for Metropolitan Architecture (OMA). “The design single-handedly changed the way we look at façade and office design to date. It has become an exemplar sustainable icon in contemporary architecture.”

The other 10 Year Finalists considered for this Award were:

• Taipei 101, Taiwan, China

• Torre Agbar, Barcelona, Spain

• Uptown Munchen, Munich, Germany

• Highlight Towers, Munich, Germany

• Time Warner Center, New York City, United States

• Bloomberg Tower, New York City, United States

• Tower Palace Three, Seoul, South Korea

All award winners, including the 2014 Best Tall Building Winners and Finalists, will be recognized at the CTBUH 13th Annual Awards Symposium, which will take place at the Illinois Institute of Technology, Chicago, on November 6. The symposium will be followed by the Awards Ceremony and Dinner in the iconic Crown Hall, designed by Mies van der Rohe.

The CTBUH Awards are an independent review of new projects, judged by a panel of industry experts. Projects are recognized for making an extraordinary contribution to the advancement of tall buildings and the urban environment, and for achieving sustainability at the broadest level.

Winners and finalists are featured in the annual CTBUH Awards Book, which is published in conjunction with a major global publisher and distributed internationally each year.

The Building Team, led by local firms Caldwell Associates Architects and Greenhut Construction, had to tackle several difficult problems to make the historic building meet current Defense Department standards having to do with anti-terrorism, force protection, blast-proofing, and progressive collapse.
