In 2019, buildings greenhouse gas (GHG) emissions accounted for 21 % of global emissions, therefore regions such as Europe have strong policies to decrease such emissions. The literature shows different examples simulating energy refurbishment of buildings or districts where an important GHG reduction can be achieved, but there is a clear gap on real measurements of exemplary buildings. This paper shows an assessment of more than 100 energy-efficient buildings in Austria, showing that this GHG emissions reduction is really possible. The paper evaluates residential and non-residential buildings, where the energy consumption was 50 % below the consumption of typical multi-apartment buildings. Moreover, the emissions in such buildings were well below the Paris agreement targets. • Assessment of more than 100 energy-efficient buildings in Austria. • GHG emissions reduction is possible in real buildings in Europe. • Residential and non-residential buildings. • Energy consumption was 50 % below the consumption of typical multi-apartment buildings. • Emissions in such buildings were well below the Paris agreement targets.
