Energy-intensive building

General information

A lighthouse project of ecological construction, centrally located in Bonn.With a construction that combines ecology and economy, the innovative project demonstrates that timber construction can be the answer to the question of how to reconcile sustainability and future viability in multi-storey housing construction.In addition to the maximum use of wood from the supporting structure to the façade to the interior, this building was completely insulated with cellulose. For the first time in a building of its kind and size. Even the fire walls were made of wood.Large rooms, sun, fresh air, bright rooms, high quality of stay with low primary energy use. Classic investor models were interpreted quite differently here: a partnership approach between investor and architect. All approaches were questioned and optimized for sustainability.The building achieves a plus energy standard (based on the passive house construction method). Through an innovative building automation, all energy services are controlled and thus the own electricity consumption is maximized.An unbelievable living comfort is achieved while at the same time minimizing primary and final energy costs.

Owner approach of sustainability

The post-war house on the inner city plot was dilapidated. The aim was to create a sustainable student accommodation, which benefits investors, users and the environment.

Architectural description

Wood as a building material should find maximum use. Large rooms, sun, fresh air, bright rooms, high quality of stay with low primary energy use. Classic investor models were interpreted quite differently here: a partnership approach between investor and architects. All approaches were scrutinized and optimized for sustainability.

Die Architekten haben den nachhaltigen Ansatz in vielen Details auf die Spitze getrieben Beispielsweise die Kellerdaemmung ebenfalls in Zellulose ausgefhrt....

If you had to do it again?

Would we go the way even more consistently and make even fewer compromises.

Building users opinion

The residents are consistently involved in the residential principle. You should learn sustainability! We are currently harvesting lettuce and vegetables from our own garden. The students have very quickly appreciated the difference in comfort. The high quality of living speaks around and the demand is very high!
