Steel piles utilising ground-source heat

Office building Technopolis Innova 2, located in the centre of city of Jyväskylä, is extended with another 6-storey building, about 10,000 gross square metre.

  • The Technopolis Innova 2 office building is the first building in Finland to use energy piles utilising ground-source heat.  The energy piles were jointly developed by Ruukki and Uponor.
  • The steel piles used in foundation construction serve as both the foundation and as energy piles collecting free energy from the ground.
  • Energy piles are ideal for commercial buildings, where both heat and cooling are required.
  • The use of energy piles improves the energy efficiency of a building and reduces its carbon footprint.
  • Ruukki will also deliver the building’s steel frame and prefabricated wall elements including structural design and installation.
  • The building is designed to fulfill the requirements for Energy Class B. LEED certification will be pursued for the building.

”Energy efficiency was a particularly important aspect in construction of the building. Energy piles meet about 50% of the building’s energy requirement for heating and 40% of the energy requirement for cooling. The first experiences of the system have been very encouraging.”
