On April 6,
Finland-based steelmaker
Ruukki announced that its energy piles utilizing ground-source energy have been chosen for the foundations of the new Technopolis Innova 2 office building under
construction in Jyväskylä,
Finland.
Ruukki is to deliver a total of 367 steel piles, almost five kilometers in length when laid end to end, for the foundations of Innova 2. One tenth, or 38, of the piles will also serve as energy piles.
Ruukki's steel piles will serve both as the building's foundations and as energy piles to collect free ground-source heat.
The building has been designed as energy class B and LEED certification will be applied for. NCC Rakennus Oy is the building contractor.
The steel piles are being made at
Ruukki's works in Pulkkila,
Finland, and deliveries for the project in Jyväskylä have already started. In addition to energy piles,
Ruukki will also deliver the steel frame and prefabricated wall elements, including installation, for the Innova 2 building. The building is 10,000 floor square meters and is scheduled for completion in spring 2012.
