Aalborg Forsyning (Utility) has taken an important step in the green transition with the establishment of a new discharge pumping station and a heat pump building at the Renseanlæg Øst (Wastewater Treatment Plant). The solution increases wastewater handling capacity while utilising heat from treated wastewater for district heating, contributing to a fossil-free future and energy-efficient heating for 1,300 homes.

The assignment comprised the design of a discharge pumping station with increased capacity and a separate building for installing heat pumps for district heating. The overall architectural concept focuses on creating a cohesive, unified expression that harmonises with the existing industrial surroundings while presenting the buildings as attractive and functional workplaces.

The buildings maintain a consistent and industrial architectural identity, with façades clad in glossy sinusoidal aluminium panels. This material choice is used throughout the site's technical facilities, creating a strong visual coherence. The façades are articulated with frames and openings that reflect the buildings' functionality, and daylight plays a central role in creating bright, inviting working environments.

Integrated into the surroundings

The exterior expression is complemented by a carefully considered lighting strategy, in which the buildings are illuminated artistically in the evening, highlighting their technical function and creating a dialogue between the buildings, the context, and the user. Climate-conscious material choices have also been made, including the use of recycled aluminium and green roofs with grass that help integrate the buildings into the landscape.

The project demonstrates how technical facilities can be integrated with high-quality architecture that supports functionality while adding value to both staff and the surroundings.
