Mr. Chris Hughes:

Regarding the harmonisation of the energy ratings scale, different member states have adopted different approaches. In Ireland, for example, we have ratings of A1, A2 and A3, etc., and this scales down to a G rating in buildings with poor energy efficiency. At the higher end of the scale, buildings will have close to zero energy use. There is close banding in respect of differentiation between buildings. An A1-rated energy-efficient building today will still be energy-efficient in the new classification regarding its low-energy use and use of renewable energy. The recasting, and subsequently having ratings on a scale of A to G, will simplify things for consumers. It will also mean it will be easy to compare building ratings in respect of the classifications used by the different member states.
