Piispantorni (Big Blue)


Artistic – even magical – atmospheres created in a multipurpose office environment with Helvar lighting control solutions

In Piispantorni, Hartwall’s former brewery building, on the border of Turku and Kaarina, 2,700 m² of new office space for companies with 1-80 people is being renovated. The ocean-themed Big Blue complex was designed by visual artist Mauri Kosonen and architect Heimo Paukkunen. In the dark, the works and the entire building create the effect of an undulating, “under water” experience. In Piispantorni, you work “under water”, in spectacular, inspiring and comfortable spaces.


Several companies have been instrumental in delivering this project. The lighting was designed by Turku Energia’s design manager, Antti Viertamo, and visual artist Kosonen. The Facade and interior lighting was carried out by Turku Energia Verkostotekniikka and Turku Laatusähkö Oy. The entire interior lighting of the building is controlled via Helvar’s Imagine router system, with Loisto Pro Oy responsible for programming the system. The main contractor for the renovation is Teräselementti Oy.
The lighting control needed to support the beautiful interior, the design and the architecture of the space. “Lighting is integral in this project for creating that unforgettable experience. Our Imagine system was an excellent choice for this project, offering flexibility, energy management, comfort and end-user control”, explains Ilkka Mäkelä, Global Service Sales Director, Helvar.
Big Blue is able to successfully reduce the amount of energy used through the installation of Imagine, benefiting from presence and absence detection as well as intelligent insight reports which highlight where energy could be best saved.
“When you enter the office space on the first floor, the light twinkling through the glass ceiling is the first thing that comes on when all the spotlights accentuating the wall panels are dimmed, and the lighting in the central corridor is only at 2 per cent power. Upon entering the space, this creates a memorable experience before the next sensor raises the lighting to normal levels. This was our first project implemented with Helvar routers, and I got a lot of help from Helvar in designing the system. I can definitely recommend this system to others”, explains Antti Viertamo, Design Manager, Turku Energia.
