This directive provides for the generalization of "passive" or energy-producing buildings on the 2020 horizon, with an obligation for public buildings to implement this policy from 2018. This text stipulates that in a quarter of a century, at least 25% of new buildings are neutral or positive on the energy balance of their consumption.
