The greenest and most sustainable office in the world

The recently completed NuOffice in Munich, Germany, has been awarded the internationally recognised Leadership in Energy and Environmental Design (LEED) certificate at Platinum level. This makes it possibly the most sustainable office in the world to date.

LEED is a certification programme that provides third-party verification of green construction, addressing the entire lifecycle of a building. See www.usgbc.org/leed for more details.

Thick insulated exterior walls and triple-glazed windows provide a good thermal insulation. Scientists from the Fraunhofer Institute for Building Physics (IBP) in Germany have been involved, too. Their aim was to optimise energy reduction as well as to adopt renewable energy resources. To do so, they used radiant heating and cooling systems, switchable glazing and innovative insulating material.

“At the end of the year we expect a primary energy consumption of about 30 kilowatt-hours per square meter and year,” says Michael Krause, group manager Systems Engineering at the department for Energy Systems at IBP.

“Conventional new office buildings which don’t have any ambitions concerning energy savings range between 100 and 150 kilowatt-hours per square meter and year.” Compared to older office buildings he expects an energy saving of up to 90%.
