Gammel Hellerup High School Multi-Use Hall
The new multi-use hall at Gammel Hellerup High School in the north of Copenhagen, Denmark, was built 5 metres below the surface of the schoolyard, between existing school buildings.
The 1,460 m2 hall is used for sporting events, as well social and cultural celebrations. Only the curved roof is visible from outside, and offering pupils a unique spot to socialize and play.
The subterranean multi-use hall was built with a focus on sustainability. It uses geothermal heat, which in the summer can be "reversed" and used to cool the air in the hall. In addition, a solar power plant was built on 125 m², and covers about 80% of the facility's total electricity consumption. Energy consumption was further reduced by a number of skylights installed in the roof to take full advantage of daylight.
HeidelbergCement Denmark supplied 1,800 m³ of mainly high-strength concrete for the project.
