The Swedish biomass-fuelled CHP plant, Värtaverket, is shortlisted for a World Architecture Festival Award in the category “Production, Energy and Recycling”. The project is designed by Gottlieb Paludan Architects and Swedish architects Urban Design.

Värtaverket is among the largest biomass-fuelled CHP plants in the world and reduces Stockholm’s CO₂ emissions by 126,000 tonnes a year. The new plant is fuelled by by-products from the forestry industry and generates 750 GWh of power and 1,700 GWh of heating annually, corresponding to the heating consumption of around 190,000 flats.

The plant façade is wrapped in curved brick components, which may be regarded as a subtle nod to the fine, old industrial buildings in the area and add a warm, red glow and tactile finish to the technical facility.The brick components take the form of vertical slats which cover the exterior of the plant and allow for adjustable and flexible positioning of the necessary openings in the underlying building envelope.

The winners of this year’s WAF Awards will be announced at the World Architecture Festival in Berlin in November.
