Article 4 requires Member States to adopt a methodology for calculating the energy performance of buildings in accordance with Annex I (numerical indicator of primary energy use expressed in kWh/(m2.year), plus indicators for net useful energy demand and operational GHG emissions in kg CO2eq/(m2.year)). Article 5 sets minimum energy performance requirements (national thresholds) for buildings or building units. Article 6 requires the calculation of cost-optimal levels of minimum energy performance requirements every 5 years (in accordance with the comparative methodology framework), and gap reporting where the national requirement differs by more than 15% from the cost-optimal level.
