Insight

A revolutionary mixed-use building in Oslo is setting new standards in sustainable architecture by eliminating traditional HVAC systems in favor of a zero-energy ventilation system.

Designed by Snøhetta and part of the Norwegian research program FutureBuilt, this building aims to achieve a triple-zero goal: no energy purchased for heating, ventilation, or cooling. This is realized through innovative design choices such as natural ventilation, geothermal energy, and structural adaptations that optimize airflow.

The building, located on a former parking lot by the river, is strategically designed to block wind while maximizing sunlight and natural air flow. Its unique angled façade and tapered shape enhance the building’s ventilation efficiency.

Sensors inside and outside monitor environmental conditions to regulate air flow, eliminating the need for traditional forced-air systems. This not only reduces energy loss but also cuts the building’s emissions by half compared to conventional structures.

The offices in the building use a radiant heating system, which directly warms people and surfaces without heating the air, providing a more even temperature throughout.

This system has proven effective even in cold weather, with fewer than 7% of occupants reporting discomfort. The benefits extend beyond energy savings to include more spacious office environments and a stronger connection to the outdoors, with natural sounds and temperatures contributing to the ambiance.

Despite its many advantages, the building faces regulatory challenges due to its unconventional systems. However, these regulations are being challenged to adapt to more innovative, sustainable building techniques that could set a precedent for future constructions.
