Christensen & Co Architects recently completed the first phase of Lund’s City Hall, a building that when complete, will be the greenest City Hall in all of Sweden. Designed with a pleated W-shaped plan, the building’s curtain walls bring in natural light and offer views out towards the landscape. The City Hall is located at Lund’s historic city center and will host 269,000 square feet of office space, conference facilities, a public ground floor, and accessible green roof.
Equipped with solar panels and earth water cooling, Lund City Hall only uses a fraction of the energy normally consumed by typical government buildings. Its dynamic, W-shaped facade was key in reducing the building’s energy footprint, and each facade is carefully oriented to optimize passive technologies and solar heat gain. The north-facing facades are completely glazed to maximize natural lighting indoors, while the south-facing facades are covered with dynamic solar-control panels that respond to daylight conditions. The facades facing the city center are designed with classical features to match region’s historic character.
The accessible green roof also plays a big role in making Lund City Hall energy efficient. In addition to sequestering carbon, the green roof helps regulate internal temperatures, store rainwater, and provide natural habitat for local flora and fauna. The green roof also acts as an extension between the neighboring new park and the adjacent historic city center.
