- an inner city office building on a heavy traffic street, in context with the sourrounding garden area
- the existing building completely optimized especially in terms of ernergy, climate, light, open work spaces and the relation of inside and outside
- complete new thermic sytem to minimize the energy usage and for a perfect micro clima, as well as air hygienic
The existing building of the European Patent Office is located in the immediate vicinity of Vienna’s largest historically grown garden network (botanical garden and the baroque garden of Belvedere Palace) and protected from the traffic noise of the busy Rennweg street by the building in front of it.
driendl*architects developed a completely optimized thermal and spatial concept for the existing building, in order to significantly reduce the previously high energy consumption and to place the building in the context of its surroundings.
The integration of openable glass surfaces enables passive use of solar energy. In addition to window ventilation, controlled draft-free ventilation is planned for optimal air hygiene.
The daylight supply of the open work rooms is achieved through sun protection with light control.
A four-story winter garden with shading in the form of adjustable slats complements the building in the south. This acts as an internal communication zone through all levels, and furthermore it is possible to use the sunlight on clear winter days.
Above of the new entrance a pergola covers the newly defined forecourt to ensure necessary hold for a laminar greening. The two flat roofs above the ground floor on the eastern side are intensively greened.
In addition to this optimization of the microclimate and energy consumption, the entire building is in direct contact with its immediate surroundings, for exemple the Botanical Garden Vienna.
