Powerhouse Telemark
Architects: Snøhetta
Year: 2020
Area: 8403 m²
Location: Dokkvegen 11, 3920 Porsgrunn, Norge

The energy sector and building industry account for over 40% of global industry’s heat-trapping emissions combined. As the world’s population and the severity of the climate crisis continue to grow, precipitating global disruptions such as the COVID-19 pandemic, architects are challenged to work across industries to build more responsibly.

As part of the Powerhouse series, Powerhouse Telemark sets a new standard for the construction of environmentally sustainable buildings by reducing its yearly net energy consumption by 70% compared to similar new-construction offices, and by producing more energy than it will consume over its entire lifespan. Through standardized interior solutions and co-working spaces, tenants can scale their office spaces as needed, granting much needed flexibility in a global context where remote working solutions continue to increase in demand.

In obtaining the BREEAM Excellent certification as proof of their bold sustainability ambitions, Powerhouses stand as beacons of sustainable design not only in their local communities, but also function as models for how the world can embrace sustainable architecture and design at large in the future.
Just like its ambitious sister projects Powerhouse Kjørbo, Powerhouse Montessori and Powerhouse Brattørkaia, Powerhouse Telemark aspires to be model for environmentally, socially and economically sustainable architecture, while also challenging our conception of what our offices might look like in the post COVID-19 era.

The skewed and slightly conical building features a clearly defined 45° tilting notch on the east-facing façade, giving it a clearly identifiable expression that stands out in the industrial context of the surrounding Herøya industry park.

The building’s striking 24° tilted roof gently slopes to surpass the extremities of the building’s volume, expanding the roof’s surface and ensuring a maximum amount of solar energy can be harvested both from the photovoltaic canopy and the building’s PV-cell clad south-facing façade.
