   Sammanfattning : The building sector is the biggest energy user in the European Union (EU) and therefore, has an important role to play in meeting the energy and climate goals ofEU. In Sweden, more than 80% of the two million detached houses are more than 35 years of age. Energy efficiency renovation of those old houses can reduce primaryenergy use by 65% to 90%. LÄS MER
