National museum in new light

By on January 1, 2019

“The National Museum in new light – A complex renovation is finished”, so DN chose to call this trip, which began in June 2014 and lasted for a full four years.

One of the biggest challenges in this long project was to be able to maintain the 150-year-old cultural heritage while developing the building for modern requirements and needs. One starting point was to meet the needs of the business in terms of climate, security, accessibility etc.

In order for the building to work for a modern museum activity with varying activities and varying exhibitions, 13 climate zones are defined in the exhibition halls. For each climate zone, there are four different climate scenarios, this because the climate (temperature and relative humidity) must be flexible, i.e. The museum will be able to regulate the climate individually for each climate zone and adapt it to the requirements of the current exhibition. The entire control unit is built on 12 appliance cabinets that serve 23 air handling units, a heating sub-unit, a cooling sub-unit and a lot of other technology to make the whole system work according to set requirements.

When they should make room for these cabinets and air handling units, the next challenge arose, where would this be placed? The solution was to build new technology rooms, buried in the rock under the museum’s two light yards. This proved to be more difficult than planned, as the blasting on some parts risked causing both cracks and high vibrations, which led to the fact that the rock masses had to be cut. 5,300 cubic meters of stone and an elevated floor later, the technical rooms stood ready.

– It has been an exciting and challenging project where we have really got the use of Nordomatics broad expertise. We have also had a very good collaboration with our client Skanska, the developer Statens Fastighetsverk, projectors and subcontractors. This collaboration has ensured that the project has become exceptionally good and appreciated. Although the museum is now opened, the work on climate and energy optimizations continues where Nordomatic is largely involved, this group that we are part of is called KIG (Climate, the adjustment group). I am very proud to be a part of this team that has performed the steering contract on one of Stockholm’s or perhaps Sweden’s coolest buildings, says project manager Conny Johansson, Nordomatic
