Award-winning architecture

The Itämerentorni building was completed in 2000 to serve as the head office of Sitra, the Finnish Innovation Fund. The architecture of Itämerentorni has won both domestic and international awards. Designed by architect Pekka Helin, the building’s face combines weatherproof, recyclable steel with glass. When it was completed in 2000, Kiinteistö Oy Itämerentorni won the Steel Structure of the Year award granted by professionals in the field.

Environmentally friendly and energy-efficient

Through the years, the energy and water consumption and co2 footprint of Itämerentorni has been reduced by as much as tens of percent. As a result of the increased efficiency of recycling, waste has been reduced and electricity is produced through renewable energy sources. The building is connected to district heating and a cooling system that utilises cold water from the bottom of the sea. The building and property management have received the international BREAAM environment certificate with a rating of “Very Good”.


A solar power plant has been installed on the roof of the property (low section). It covers approximately 5% of the property’s annual electricity consumption. In 2020 and 2021, wind power is produced in the TuuliMuuko wind farm in Lappeenranta that is owned by Exilion. The company is one of the few Finnish investment companies investing in renewable energy and wind power.

Domestically owned

Itämerentorni is owned by the domestic real estate investor Exilion. Founded in 2005 Exilion manages a property portfolio amounting to over EUR 750 million through three limited partnerships. Exilion owns office and hotel premises in the capital region as well as Hansakortteli, the largest shopping centre in Finland Proper, in Turku.

Facility management

“I have worked here since the construction phase, so I am familiar with each square metre of the building. I take care of the building and technical building systems. My job is to make sure that all maintenance and repair work is completed. Minor issues I address myself. For example, light bulbs are replaced and the air conditioning is adjusted without delay. Ensuring the high indoor environmental quality is the most perceptible part of my job. I answer any questions related to the property. The customer cannot know who is responsible for each area, so we cooperate closely with the providers of our reception and conference services.”
