Technopolis Innova 2 in Jyväskylä, Finland is heated by energy piles

Technopolis Innova, an office building located in the centre of Jyväskylä, Finland, underwent an expansion in 2011 when a second building was constructed with a gross floor area of 10,000 square metres. The six-storey Technopolis Innova 2 building was constructed on the shore of Lake Jyväsjärvi in spring 2012.

2.3km of collection pipes and 38 energy piles

Innova 2 is the first site in Finland to use energy piles, which exploit geothermal energy and were developed in collaboration between Uponor and Ruukki. The steel energy piles are driven or drilled into the ground and they provide the building with both a steady foundation and a large amount of useable energy.

Challenging ground conditions put to good use

Nowadays, it is increasingly common that buildings need to be constructed on ground that provides poor support, so piles are required in any event. This was the case for Innova 2, as the ground in Lutakko, in the centre of Jyväskylä, is relatively soft and the groundwater is at a depth of only 1.5m.

The steel piles that are used for the foundations act as both a supporting structure and an energy solution. The energy piles exploit free geothermal energy from beneath the building. They are particularly suited for use in commercial and office buildings such as Innova 2 where there is a significant need for heating and cooling.

The heating system uses the energy that is stored in the earth, while the low temperature of the ground is used for cooling. In the summer, the cooling system outputs excess heat, which is directed back into the ground, ensuring that the temperature level of the ground remains sufficient for energy generation.

Good results from the pilot site

Ruukki supplied the site with a total of 181 piles, of which 38 were energy piles. The piles were approximately 30 metres in length and they were sunk into Uponor's PE-Xa U collection circuits using ground weights. The collection circuits were then connected to manifolds that were installed into the floor.

The pile and the manifold are connected by an insulated pipe, which minimises heat loss. The trunk lines from the manifolds are led into the heat distribution room via insulated pipes.

"Considering that this was the first site on which energy piles from Ruukki and Uponor were installed, everything went very well. The installation sequence was optimised. It was possible to install the heat collection pipes on top of the base slabs in the final phase. This facilitated circulation on the construction site," says Jyrki Kesti, Technology Director from Ruukki.

A lifecycle-efficient solution

Using energy piles improves the energy efficiency of the building and reduces the carbon footprint. Environmental efficiency has also been proven to increase occupancy rates. Innova 2 was 100% let before it was finished.

The amount of energy that Technopolis Innova 2 can obtain from energy piles has fulfilled expectations. In some respects, it has surpassed expectations.

"We have obtained very good results on this site. The output of the energy piles has been better than forecast," Kesti says.
The six-storey Technopolis Innova 2 building was constructed on the shore of the lake.

Day-care centre to be built with energy piles

As requested by the City of Vantaa, the Vaaralanpuisto day-care centre has been planned based on the "nearly 0 energy days" concept. Construction work for the day-care centre began in late summer 2016, and the project will be completed in July 2017. Project costs are estimated at EUR 5.4 million, and the day-care centre will accommodate about 130 children. Among the various energy production options available for the site, the City of Vantaa chose the energy pile and solar thermal collector system jointly developed by Uponor and Ruukki.

The New Deichmanske Library - Bjørvika, Oslo

Deichman is equipped with Thermally Active Building System - a system for storing the energy in the concrete ceiling. It is primarily a cooling system, but it can also be used as a heating system. When in cooling mode, no energy is used as the heat is drawn into the concrete, only when it is transferred from the concrete and into the water pipes that are cast in the decking. The need for installed power is reduced, and operating expenses are significantly reduced as opposed to in a air-based cooling system. The TABS is cast into the Prefab elements, which is a BubbleDeck construction with spans up to 10.5 meters.
