Located in a development zone of the Port of Aarhus, the six-story building will now serve as a landmark for the city and become known for its use of solar power. The wide South-facing facade is clad in natural stone and incorporates a 170 m2 solar wall and a 200 m2 slatted wall of solar panels that also provide shade. The 170 m2 solar wall acts as a vertical sculptural element in the corner of the building and the energy from this system is used to pre-heat the ventilation air intake in winter and to cool the offices in summer. Windows for the offices are recessed and protected from the sun with shade panels that are covered in photovoltaics, which provide electricity for the offices.
The municipality’s new office building is twice as airtight as required by the Danish building regulations and features, and features energy-friendly materials and elements with ultra-low thermal conductivity, like vacuum-insulated windows. “Normally you would try to hide the energy-efficient elements of the building, but we have decided to make a virtue of necessity and use them as sculptural elements in the facade, so that the building stands out as a distinctive image of energy architecture,” states architect and partner Mads Møller, C. F. Møller Architects.
