Hamnhuset proves the benefit of building with energy-efficiency in mind from the very outset. It is the result of advanced engineering design and the power of architectural creativity. Above all, though, it is a triumph of will – the will to challenge the conventional, the urge to face up to new problems with newer solutions.

Hamnhuset has been built to Passivhaus standard with exceptionally low energy consumption. The building has no radiators and is self-sufficient from April to November. The energy heart of the building is a ventilation heat recovery system which extracts heat from the exhaust air and transfers it to the incoming air. Good insulation and airtight walls lead to lower heat losses. District heating is utilised sparingly for heating incoming air when required and for heating water when the sun isn’t shining. Optimally positioned windows with low-E glass keep solar gain in check and the roof is clad with solar panels.

The investment costs are rapidly counterbalanced by the lower energy costs. Everyone is a winner: the client, the property owner, the residents and, perhaps most especially, the environment.

As regards architectural expression the client was looking for a contrast to the modern architecture in the old harbour and shipyard area. The design is a return to the 1950s in terms of room relationships, simplicity and purity. The energy objective has also had an influence on the way in which we have planned the façade, floor plan and system solutions.
