About 400,000 apartments need help in Sweden due to bad energy efficiancy. About a gazillion other homes around the world do too, but not all coutries act upon such matters. Their aim is to upgrade appartment buildings from the 70’s so that they would meet the standards of a passive house. To do that they will thickly insulate them, install better and more energy-efficient windows and doors, equip them with more efficient appliances and lighting and install heat exchangers. All of the rooftops facing south will also receive solar panels to provide districts with warm water. Their aim is to cut the use of energy from 216 kWh/m2 to about 92 kWh/m2.
I bow to you, queen Sweden.
