Innovation Greenhouse Bonn

The architecture features a sandwich facade made of recycled concrete (RC concrete). Containing approximately 30 percent recycled aggregates, this concrete significantly reduces the consumption of primary raw materials during production. The facade consists of 107 elements covering a total area of 1,475 square meters. These components were prefabricated in a weather-protected factory environment and installed on-site using a mobile crane, which substantially optimized the construction schedule on the tightly confined plot.

From an urban planning perspective, the building presents itself as a striking triangular structure with six main floors and a technical level, shielding the neighboring district from the noise of the railway tracks. Inside, the building encompasses around 2,900 square meters of flexibly structured "New Work" office spaces, which are primarily utilized by technology companies. Untreated exposed concrete walls emphasize the authentic materiality and the resource-conserving character of the architecture. On the ground floor, a 400-square-meter "marketplace" featuring a gastronomy area complements the commercial space and serves as a central meeting hub. In the central atrium, a spiral steel staircase connects the floors, while a green plant wall spanning all levels enhances the indoor climate.

The building meets the Efficiency House 40 standard. Photovoltaic modules on the roof and a building-integrated solar facade generate electricity for ongoing operations. Additionally, a power-to-gas system uses electrolysis to convert locally generated solar power into hydrogen for storage. The property was also consistently developed in accordance with the sustainability criteria of the German Sustainable Building Council (DGNB). Furthermore, the building receives the Quality Label for Sustainable Buildings (QNG). This certification evaluates not only the energy consumption during operation but also the entire life cycle of the property, including the manufacturing and future recycling of the materials used.

A specific detail of the building envelope provides a fitting conclusion: the photovoltaic films integrated into the solar facade simultaneously serve as bird protection alongside generating electricity.
