If you want to build a new house in Sweden you need to present an energy calculation for the house so that you meet the fairly strict requirements. Of the top of my head, a normal family house (150m2, 1-1/2 stories) is allowed to consume between 5000-6500 kWh per year (low number in southern Sweden, same as Denmark. High number northern Sweden above the polar circle). This generally means >220mm insulation in walls and roof and >300mm insulation in the foundation. In northern Sweden you need a geothermal pump to hit those numbers.
