There is great focus on safety in Project New National Museum One of the effect orientated goals of the project is:

‘The new building shall be such that the museum can keep its collections in a responsible museum way, where damages/deterioration due to constructional conditions shall be reduced to 0’. This has in turn led to a large focus on the inside climate and to ensuring that the art shall not be water damaged. This is also reflected in the pipe installations.

The building has a refrigeration centre on the 1st floor towards the north west, with direct access from vehicles. The heating and sprinkler central is located in the basement (plan 001). In the south, towards Rådhusplassen, there is a seawater intake in the basement, where the seawater pumps and seawater exchangers are. The building has a technical middle floor between the basement and the 1st floor, which connects these 3 centrals together, and which includes a large number of conduits, both for pipes, ventilation and electro. There are also 2 large ventilation rooms in the basement, 1 in the east and 1 in the west. In addition there are 6 minor ventilation rooms divided between 2 on the 3rd floor and 4 on the 5th floor.

Some of the pipe systems that are outdoors and in the bottom plate will be executed before K301 is contracted.

The extent of sanitary equipment in K301 is relatively small, apart from in the workshop areas, where, amongst other things, art is preserved. Some sanitary equipment is delivered by another contractor.

K301 shall deliver sprinkler installations for approx. 54 700 m2, divided between pre-action installations (approx. 29 000 m2), wet installations (approx. 17 800 m2) and some dry installations. In addition to sprinkling, gas-extinguishing installations shall be delivered for approx. 900 m2 by K3011, gas extinguishing installations and inert air installations for approx. 7 000 m2 by K3012 inert air installations. K3011 and K3012 have already been contracted.

K301 shall deliver pressurised air installations. Pressurised air shall be delivered to several workshops as well as the sprinkler installations.

The building has 2 refrigerating systems with free refrigeration with seawater and refrigerating machines. The building's total cooling requirement is approx. 3 000 kW. There is little local cooling in the building as the refrigerating requirement to a large degree is covered by air-cooling.

The condenser heating from the refrigerating machines shall be used in the building's heating plant, as well as for snow melting of outdoor areas. The seawater is used during the winter and work as a heating source for the refrigerating machines in heating modus and for dumping surplus heat from the condensers. District heating is used as peak load for the heating plant. As a back-up for the seawater, network water shall be used for dumping the condenser heating. The total heating requirement for the building is 2 250 kW, in addition to approx. 400 kW snow melting. Heat distribution mostly occurs with ventilation air, but there is also approx. 1 760 m2 heated flooring and approx. 430 radiators or convectors. Parts of open spaces and pavements shall have street heating.

K301 shall provide all the heating and cooling installations apart from refrigeration machines/heat pumps (K3021 Refrigeration Machines) and seawater intake/emission from a manhole outside the building (the seawater intake) and out into the sea.

The building has more than 40 balanced ventilation systems and the total volume of treated air is more than 600 000 m3/h. Most of the systems cover rooms that have special requirements for temperature and humidity, which are, therefore, equipped with both heating and cooling batteries and humidifiers. Systems for exhibition rooms have zone batteries in addition. K301 shall deliver connections to this equipment.
