In Munich, a newly erected office building, called the NuOffice, has been awarded an internationally recognised green design certification in platinum, called the Leadership in Energy and Environmental Design (LEED) certificate. The NuOffice, located in Domagkstrasse 10 in Munich, obtained 94 points. This is well above the level of 80 points necessary for platinum status. It is also world wide the highest evaluation ever attributed in the category investment buildings (core and shell).
The ambitious project has been supported by the European funded research project DIRECTION. Scientists from the Fraunhofer Institute for Building Physics (IBP) in Germany have been involved, too.
Thick insulated exterior walls and triple glazed windows provide a good thermal insulation. 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. “ Compared to older office buildings he expects an energy saving of up to 90%.
