Minimum-energy train depot by YAJ submitted for invited design competition
Four architecture practices have been selected to present their designs for the invited competition ‘Train depot of the future’; YAJ Arkitekter; SandellSandberg; MalmströmEdstoröm; and ThorbjörnssonEdgren. The following is the entry from YAJ Arkitekter.
Working with Incoord Energy Consultants, YAJ Arkitekter has proposed a train depot largely inspired by the natural environment, which ‘has an entirely positive connotation in our culture’ says Ylva Lindstedt of YAJ. The colours employed in the buildings are deliberately quiet, darkly pigmented with a hint of aubergine, while all surfaces are highly polished for maximum depth of colour and lustre.
YAJ architect Jonas Nyberg explains: “The envelopes of the buildings in dark terrazzo-concrete are wrapped by what we call ‘green tracks’ in a graphic pattern inspired by the parallel and diverging rails of a railway yard. The ‘green tracks’ serve as racks for both solar panels (on the roofs), and for evergreen climbers (on the façades).
“The ‘green tracks’ consist of bundles of metal lamellas mounted at a distance from the building envelopes. Circular, domed windows/skylights ventilate and let daylight into the interior rooms. At night, these constellations of circular openings resemble a starry sky. The gables of the buildings are glazed - as per tradition in the grand buildings of the railways.”
Much attention has been paid to the environmental impact of the train depot, ensuring that the buildings are nearly zero-energy. The solid concrete structures serve as thermal mass, buffering heat and cold and reducing the energy demands of the complex. Also included is sensor-driven natural ventilation through motorised skylights, pre-climatised fresh air supply, and waterborne floor and wall heating via solar panels in combination with geothermal heating.
