How Norway Popularized an Ultra-Sustainable Heating Method
When Karen Byskov Lindberg bought a house in Oslo in 2018, she set about a refurbishment that would drastically transform her energy consumption.
After removing the house’s old oil boiler system, she installed improved wall insulation, new window fittings, an air recovery system and, importantly, a heat pump. As a result, she says the structure’s average energy use has dropped from 35,000 kilowatt hours (kWh) per year to just 8,500 kWh – less than a quarter of what it was before.
“The energy use is extremely low,” says Lindberg, who is a 43-year-old university professor in the Norwegian capital. “It’s economically beneficial but also it reduces CO2 emissions.”
