Due to replace two existing laws on building insulation and heating systems when it enters into force later this year, the ordinance will mandate higher planning and construction standards for new buildings.
Every new building is to be issued with an energy consumption certificate.
For existing buildings, there will be new obligations to replace inefficient appliances and take other energy efficiency measures. The government is expecting 2m older heating boilers to be replaced with more efficient models, plus an increase in roof insulation and window renewal.
