Snøhetta has completed the carbon-negative Powerhouse Telemark office in the city of Porsgrunn, Norway, which was designed to produce more energy than it will consume over its lifespan. The angular building is highly insulated and has a large photovoltaic canopy covering its roof and south-facing facade that will generate 256,000 kilowatts of energy each year.
According to Snøhetta, this will mean it creates enough surplus renewable energy to compensate for the carbon consumed by the office over a 60-year lifespan – including its construction, demolition and the embodied-carbon of building materials.
