Kestävän kehityksen ratkaisut:
Interconnectivity was the main principle for the design and applies for all its parts and works on all levels. The existing buildings, which were composed of different blocks, are respected and integrated into the new design: up to 83% of the existing constructions remain.

The facades of the existing buildings are maintained, including the windows, and a “skin” is attached to them, improving the insulation value, avoiding heat losses and reducing the energy demand.

Efficiency and effectiveness are guiding principles throughout the design. In intervention, material use, footprint, costs and burdening of the environment. In return, functionality, comfort, innovation, identity and a positive impact on society are achieved.

Circularity has been an integral part of the design in many ways: respecting the majority of the existing constructions, using waste wood for the facades, reusing the concrete from the parts which were demolished, reusing the steel construction for the extensions of the buildings, recycling the asphalt from the existing roofs, reusing the existing toilets and ceiling plates and converting the existing doors into new furniture, amongst other things.

The building complex provides more energy than needed. Thanks to the use of solar panels and underground water for thermal storage, it is also CO2 neutral.
