Trondheim, Norway

City Syd is a suburban shopping centre, built on the outskirts of Trondheim. Opened in 1987 and covering an area of 28,500 m2, it was redeveloped in 2000 and it is now 38,000 m2, with 1,000 outdoor parking spaces. Its primary group of customers comes from the city of Trondheim, but it has a large catchment area and attracts customers from all over central Norway. City Syd was the largest shopping centre in the region until 2009, and remains one of the largest in central Norway.

City Syd joined the project CommONEnergy to test innovative technologies and solutions, implemented between 2013 and 2016 to be effective in 2017. The focus there is put on natural ventilation, iBEMS, as well as natural and artificial lighting:

  • Redesign of the lighting system, including the use of a rectangular lighting system for advanced daylighting, artificial lights and meters in the shopping centre gallery and the Jens Hoff shop, and a dome and light-tubes in the Jens Hoff shop. The goal is to reduce installed power for the whole lighting system
  • Natural ventilation with automatic shading and monitoring systems (Air Handling Unit, AHU, in the common area).
  • A modern energy management and monitoring system (iBEMS) allows an optimal control of all technologies, taking appropriate decisions to reduce energy consumptions.

Latest news from the works (November 2016) are available.
