Buildings are responsible for 40% of energy
consumption and 36% of CO2
emissions in the EU

By improving the energy efficiency of buildings, we could reduce total EU energy consumption by 5% to 6% and lower CO2 emissions by about 5%

While new buildings generally need less than three to five litres of heating
oil per square meter per year, older buildings consume about 25 litres on average. Some buildings even require up to 60 litres..

We will need to reduce energy demand improving energy efficiency
