The recast of the EPBD imposes that all EU member states impose near-zero energy targets for new buildings. In practice, it will require that the building airtightness level has to be assessed. one can imagine several ways to assess the airtightness, e.g. the measurement of each building, the measurement of a reference building, standard building details, .... Many people expect that indeed each building have to be measured, whereby in addition a good airtightness level has to be reached. What is your opinion?
