You wouldn't believe the minimum requirements for building insulation in this country (Norway)! With any normal grade insulation mats, you need 12 in thick mats (I am yet talking about high quality insulation). Of course you must also have a sealed wind shield so that no hot air leaks out of the house. Windows have 3-layer glass (with insulating gases between the glass layers) to fulfill the requirements.

Take my living room as an example, covering half of my first floor. It has one long outer wall of about 8 meters, two shorter walls of 4 m. They are 2,5 m tall, making 40 square meter of wall surface. The maximum permitted loss is 0.18 W/sq.m per degree temperature difference, i.e. 7.2 Watt/degree. With -30°C outdoors and I want 20°C indoors, a heater delivering 360 W should be enough to keep my living room warm.

Windows are allowed more loss, up to 0.8 W/sq.m per degree. The two 1.2 m square windows, roughly 3 square meters total, are allowed 2.4 W/degree, or 120 W heat loss when it is -30°C outside. So, I may have to raise the pwer of the heater to 500 Watt. Or maybe not - a human in ordinary social activity emits in the order of 100 W, so inviting a few friends in should be enough.

The basement floor to the ground is only allowed 0.1 W/sq.m per degree. The ground two meters below the surface doesn't go much below freezing (the ground usually freezes about one meter deep in cold winters). So a 100 sq.m basement heated to 20°C (20 degrees above the ground temperature) should have a maximum heat loss through the floor of 200 W.

These are not extreme cases, it is the minimum requirement for new buildings. We will of course save a lot on the heating bill, but it most definitely does help keeping down the cost of putting up a new house!

In my opinion, the authorities have gone too far in their eagerness to save energy.
