GK Miljöhuset - Norway's most energy efficient office building!

GK Miljöhuset was inaugurated in 2012 and even though it wasn't any new tech solutions as such, it is still Norway's most energy efficient office with 67 kWh / m2 and year. The focus was bout doing everything right and the level of ambition was set very high. The construction workers and installers constructed a building they thought was fun and interesting to work with.

GK Miljöhuset was inaugurated in 2012 and even though it wasn't any new tech solutions as such, it is still Norway's most energy efficient office with 67 kWh / m2 and year. (In Norway, this is calculated in a different way than in e.g. Sweden). The focus was more about doing everything right and the level of ambition was pretty high. The construction workers and installers constructed a building they thought was fun and interesting to work with.

The office has the  "Energy Label A" standard and is Norway's first officebuilding built according to the Swedish passive house standards (minimized heat losses, optimised heat gain.) The property has an air-water heat pump, triple glass windows, exterior sunscreen, 40 cm insulation, airtight facade (0.23 l / s, m2) and our products for demand controlled ventilation and lighting. The lighting has no daylight compensation or LED. The property is owned by GK and it is built as a total technical contract where GK has been responsible for planning and implementation and tehy are very pleased with it.

With GK's own department for building automation, a system has been built in as "delivery standard". Everything is web-based and our interface LINDINSPECT is nicely linked to it for total control of the indoor climate.

About the ventilation:


The building has six units set to start when more than five units register presence. The units are divided on the facades. Pressure regulating dampers have been installed on each floor but apart from that, there are no dampers or silencers. This due to reach low SFP numbers. Cooling is produced by the heat pump and since there is no waterborne heating system in the building, the cost of piping has been kept to a minimum. The only additional heat they can get is from a 200 W heater integrated into the branch rods. The accuracy in flow measurement and balance is extremely crucial to avoid whistling doors etc.
