Nationalmuseum

Project Description

The National Museum is Sweden's largest art and design museum. It is also a government agency tasked with promoting the arts. The collections include paintings, sculptures, miniatures, arts and crafts, designs, drawings, graphic sheets and portrait photographs. In total, the collections consist of approximately 700,000 objects from the 16th century to the present day.

Our input

Bengt Dahlgren AB has had the prestigious opportunity of designing new ventilation, air conditioning, sprinkler, control and monitoring systems. We also ensure that the energy and environmental targets are met.
Since 2013, the National Museum has been closed for the extensive renovation. In the demanding environment of a museum, where everything must be planned based on the perspective of preserving the art, the assignment has been unusual and challenging.

Bengt Dahlgren has developed a unique solution where the air conditioning and sprinkling of the premises takes place via the ceiling roses in the vaults 12 meters above the floor. This means that a unique supply air device has been designed to supply humidified air to the premises so that the high climate requirements can be maintained. The sprinkler head is also located in the center of the ceiling rose. Everywhere, behind windows, walls and floors, ventilation pipes, sprinkler devices and climate solutions that manage temperature, humidity and fire safety are hidden.

Technically, it cannot be compared to how it looked before. The entire National Museum is now divided into different climate zones, which makes it possible to have an exhibition that maintains a certain climate in one hall and another exhibition that requires a completely different climate in the next.

Key Features

An obvious starting point during the renovation has been to meet the needs of the business in terms of climate, safety, accessibility, fire safety and logistics. Requirements that are absolutely necessary to conduct museum operations today and to remain the building that Friedrich August Stüler designed, which was built in the 1860s, to be Sweden's foremost art museum. This is also where the great complexity of the project lies.
