In Lund, a city in southern Sweden, the MAX IV Laboratory houses a synchrotron, a giant particle accelerator. Unfortunately, scientists there found the facility was buffeted by ground vibrations from a nearby highway. They discovered even the smallest vibrations could throw off their precise studies. Instead of finding a new site, the lab decided to use smart landscape design to create a solution. Working with Fojab Architects, landscape architects with Danish multidisciplinary design firm Snohetta created a 19-hectare park that absorbs vibrations while creating public space, a constructed meadow land, that also captures stormwater.
On their web site, Snohetta writes that ground vibrations are “commonly created by wavelengths between 10 to 40 meters in height and follow the surface of the ground.” If a landscape is flat, their models showed, vibrations could reach the laboratory. But experiments with different types of wave topography found that certain forms could actually absorb the vibrations.
Snohetta used the software program Grasshopper to model the effects of vibrations, defined at 10 to 40 meters at an amplitude of 4.5 meters, on their site. The primary lab building had to be a circle. But they decided to twist and raise it, creating a “dynamic shape based on the Möbius strip,” which is a surface with one side and one boundary. And then they went further, creating a sort of Möbius volume. Landscape wave forms radiate out in a pattern that breaks up incoming vibrations. According to Snohetta, “the more chaotic combinations of waves, the better.”
To build this intricate landscape, Snohetta uploaded the 3D model directly into to the GPS systems guiding the bulldozers who carved the shapes. For the firm, it was like “having a giant 3D printer producing the project on a 1:1 scale.”
On top of blocking the vibrations, the designers also brought a sustainable design approach — soil was cut on site and then filled in elsewhere to create the waves. They argue this will help ensure the site can return to agricultural use if the synchrotron is no longer used.
The waves also help channel stormwater into ponds designed to accommodate both 1-year and 100-year rain events.
And throughout the park, there are native meadow grasses, planted from seeds gathered at a nearby nature reserve. The lab will bring in sheep to help manage the grasses.
Even though the location looks fairly suburban, there is also ample bike parking for lab employees and visitors.
