Mr. Seán Armstrong:

The figure is just to give the Deputy the full context and indicate the work done in the period from 2013 to the end of 2021. The more advanced standard was introduced in 2021 and that is a B2 BER rating. The target is for 40% of dwellings to achieve that more advanced standard. Of those 136,000, because they are new dwellings built to advanced building regulations since 2008, 36,000 are already at a B2 level. We have a further 36,000 that we want to bring to a B2 level by 2030. We have 75,000 units where we have done shallow retrofits. That is how we describe it and it typically comprises attic insulation or cavity wall insulation. All dwellings will see some level of retrofit. The newer dwellings and the 40% that will have been retrofitted will be at the B2 level or better in 2030.
