Project report

The United World College is located in Dilijan, in the mountains of the Lesser Caucasus and has been in operation since October 2014. In 2016 more than 200 students from over 40 nations were accommodated and trained there. In the near future this number is to be increased to 650. The challenge for the architects was to integrate the building as far as possible into the surrounding environment. The former orchard in a fertile valley was to be re-established as soon as possible. Therefore, the project includes green roofs and facades consisting to a high degree of locally available raw materials. A build-up based on the drainage element Floradrain® FD 40-E was realized on the entire roof surfaces. Since Armenia’s soils contain material of volcanic origin, the substrate was mixed from local material. Strips of turf were peeled manually from nearby flat pastures and were laid along the edges of every roof to achieve protection from wind. On the inner surfaces seeds were brought out.

  • Bird`s eye view of vegetated areas on the roof
    In 2015 the planners have received the International Green Roof Leadership Award for green roofs and walls.
  • Green roof with skylights
    In order to preserve and increase biodiversity the roofs are mowed only twice a year.
  • Plants on a green roof
    The plants on the roof surfaces are supposed to grow as naturally as possible.
  • Vegetated facades and curved green roof areas on a large building
    Vegetated facades enhance the green appearance of the building.
