One of the most ambitious goals of the Katajanokan Laituri project is to build a carbon-neutral office building which uses energy solely from renewable sources and is completely CO₂-neutral, both in construction and operation.

Stora Enso the global renewables leader will be the main tenant of the new 23 000 m² premises.

The aim is to achieve this by planning the entire building as timber construction and relying exclusively on renewable energy sources. It is being built using 6 500 m³ of sustainable Sylva CLT Walls, Floors and Roofs and 2 000 m³ Sylva LVL Beams and Columns.

Even the window fixtures are sustainable! Sounds small in size (97 m³) but the wooden components are mighty in strength. The Effex™ and Glue-lam fixtures support 700 windows weighing 210 tonnes. That's as heavy as 50 hippos!

The windows will enable the maximum amount of natural daylight and further reduce energy consumption.

The building will store 5 865 tonnes of carbon dioxide. (To put that in perspective, diesel produces 1 tonne after driving 6 000 km).

In addition to Stora Enso and the hotel, other companies will also be able to rent space in the extensive complex. The property is being developed by the Finnish pension insurance company Varma, which has set itself the goal of having a climate-neutral investment portfolio by 2035. To this end, the company has sold its investments in coal and oil and is instead investing in emission-free electricity and climate-neutral heating.
