Hochhaus Bugginger Straße 50, Passive house high-rise in Weingarten District, Freiburg im Breisgau, Germany
Hochhaus Bugginger Straße 50 is a 16-story residential tower with 139 apartments spread across around 7,000 square meters of living space. The building stands about 45 meters tall and defines the skyline of Freiburg's Weingarten neighborhood with its clean, modern form.
The tower was built in 1968 and underwent comprehensive renovation work between 2009 and 2010. This transformation made it the world's first certified passive house high-rise, setting new standards for energy-efficient building practices.
The residence serves as a gathering place for people living here, with shared spaces and guest apartments that help neighbors connect. These areas create opportunities for daily interaction and strengthen bonds within the community.
The building is best reached on foot or by public transport, as it sits in a well-connected residential area. Keep in mind this is an occupied residential building, so access to private spaces will be limited for visitors.
The facade received thick thermal insulation and the roof was fitted with even heavier insulation, while all windows were upgraded to triple-glazing. These technical changes are hard to spot from outside, yet they form the core of the building's energy system.
