EU sets stricter rules for energy performance of buildings

The EU Council reached agreement Tuesday to ensure all new buildings will be zero-emission buildings by 2030 and existing buildings transformed into zero-emission buildings by 2050. The revision of the Energy Performance of Buildings Directive also stipulates that existing buildings should be transformed into zero-emission buildings by 2050.

As regards new buildings, the revision of the Energy Performance of Buildings Directive stipulates that from 2028 new buildings owned by public bodies would be zero-emission buildings, while from 2030 all new buildings would be zero-emission buildings. Exceptions will be possible for some buildings, including historical buildings, places of worship and buildings used for defense purposes.

For existing buildings, member states agreed to introduce minimum energy performance standards that would correspond to the maximum amount of primary energy that buildings can use per m2 annually. The purpose is to trigger renovations and lead to a gradual phase-out of the worst-performing buildings and a continuous improvement of the national building stock.

For existing non-residential buildings, member states agreed to set maximum energy performance thresholds, based on primary energy use. A first threshold would draw a line below the primary energy use of 15% of the worst-performing non-residential buildings in a member state. A second threshold would be set below 25%. Member states agreed to bring all non-residential buildings below the 15% threshold by 2030 and below the 25% threshold by 2034. The thresholds would be set based on the energy use of the national building stock on 1 January 2020 and may be differentiated between different building categories. For existing residential buildings, member states agreed to set minimum energy performance standards based on a national trajectory in line with the progressive renovation of their building stock into a zero-emission building stock by 2050, as outlined in their national building renovation plans.

The national trajectory would correspond to the decrease of the average primary energy use in the whole residential building stock over the period from 2025 to 2050 with two control points to keep stock of member states’ achievements. These would ensure that the average primary energy use of the whole residential building stock is at least equivalent to:

– by 2033, the D energy performance class level
– by 2040, a nationally determined value derived from a gradual decrease of the average primary energy use from 2033 to 2050 in line with the transformation of the residential building stock into a zero-emission building stock.

Member states agreed to add a new category “A0” to the energy performance certificates that would correspond to zero-emission buildings. Furthermore, member states will be able to add a new category “A+” corresponding to buildings, which in addition to being zero-emission buildings contribute on-site renewable energy to the energy grid. The energy performance certification for buildings, previously set by the directive, ranks buildings on a scale from A (best performing) to G (worst performing) based on their energy performance.
