SNØHETTA

Powerhouse Telemark in Porsgrunn, Norway, is a pioneering energy-positive office building that produces more energy than it consumes over its lifetime. The structure’s diamond-shaped form is optimised for capturing solar energy, with its façade covered in photovoltaic panels. The building features a natural ventilation system and highly efficient insulation to minimise energy consumption. Inside, workspaces are designed to maximise natural daylight, reducing the need for artificial lighting. This project showcases Snøhetta’s commitment to environmental responsibility by combining innovative architectural solutions with sustainable practices. As a landmark in energy-efficient design, it inspires future developments by demonstrating that sustainability and aesthetic appeal can coexist harmoniously.

Under, located in Lindesnes, Norway, is Europe’s first underwater restaurant and doubles as a marine research centre. Its monolithic concrete shell was designed to integrate into the marine environment, allowing sea life to thrive and creating an artificial reef over time. The building features large panoramic windows, offering diners a mesmerising view of marine life while also maximising natural light, reducing energy usage. Sustainable materials and passive design principles were prioritised throughout the construction process. Under’s dual purpose highlights Snøhetta’s dedication to sustainability and environmental awareness. By merging cutting-edge design with ecological innovation, Under fosters a deep connection between humans and the natural world, embodying Snøhetta’s vision of architecture in harmony with nature.

The Calgary Central Library in Canada embodies sustainable architecture and community-focused design. Its high-performance façade includes triple-glazed windows and a central atrium, reducing energy loss and maximising natural light. Low-emission materials and sustainable wood were used throughout, and its adaptable design ensures long-term relevance. Beyond environmental impact, the library fosters inclusivity and community engagement, reflecting Snøhetta’s belief in socially impactful spaces. As a cultural hub, it promotes accessibility and lifelong learning while setting a benchmark for energy-efficient public buildings. By seamlessly integrating sustainability with striking aesthetics, the library demonstrates how architecture can balance ecological responsibility with functionality and beauty

Vertikal Nydalen in Oslo, Norway, exemplifies sustainable innovation as the country’s first naturally climatized commercial building. It employs geothermal wells, photovoltaic panels, and natural ventilation to achieve energy neutrality, with no energy required for heating, cooling, or ventilation. Vertical greenery enhances urban biodiversity and reduces its carbon footprint. The building’s design optimises passive heating and cooling, combining advanced engineering with eco-friendly materials. Vertikal Nydalen creates vibrant spaces for work and leisure, fostering community engagement while redefining energy-efficient architecture. This project sets a new standard for sustainable design, proving that functionality and environmental responsibility can align seamlessly.

Powerhouse Kjørbo in Sandvika, Norway, transformed two existing office buildings into energy-positive structures, showcasing the potential for sustainable refurbishment. Solar panels generate more energy than the buildings consume, while improved insulation and efficient ventilation reduce energy use. Sustainable materials were prioritised, minimising environmental impact. This renovation avoids construction waste and reduces emissions compared to building anew. Powerhouse Kjørbo provides functional, comfortable office spaces while setting an example for revitalising outdated infrastructure sustainably. It remains a prototype for energy-positive retrofitting, inspiring architects and developers to consider ecological upgrades for existing structures, demonstrating that sustainability can drive architectural innovation.
