To contribute to carbon neutrality in 2050, French construction actors will have to transform the majority of the housing stock to achieve an average Energy Performance Certificate (EPC) level of “B”. Compensating for buildings that cannot achieve this, and to raise the overall ambition, ultra-efficient renovations make it possible to reach energy consumption levels close to zero (EPC “A”) wherever possible. The EnergieSprong approach, initiated in the Netherlands in 2012, assists the development of projects allowing for mass uptake of renovations that target an “E=0” performance goal: a house producing as much energy as it consumes after renovation. These projects use prefabricated solutions to make rapid renovations possible.
