Ar ôl y cyfnod yr ymdrinnir ag ef yn yr adroddiad, mae Llywodraeth Cymru wedi cyflwyno newidiadau i Ran L o’r Rheoliadau Adeiladu. Ymhlith y newidiadau hynny mae targed o welliant o 8% mewn effeithlonrwydd ynni cartrefi newydd, a gwelliant o 20% ar gyfer adeiladau annomestig (o’i gymharu â safonau 2010). Cafwyd newidiadau hefyd i’r modd yr ymdrinnir ag adeiladau sydd eisoes yn bod. Ar ôl i ‘Welliannau Canlyniadol’ gael eu cyflwyno, bydd gofyn i berchentywyr gymryd camau lliniaru syml ond costeffeithiol wrth iddynt estyn eu cartrefi neu addasu rhannau ohonynt.
Following the period covered by the report, the Welsh Government has introduced changes to Building Regulations Part L. These changes include a target of 8% improvement in the energy efficiency of new homes and a 20% improvement for non-domestic buildings (compared to 2010 standards). There have also been changes to the way that existing buildings are treated. The introduction of ‘Consequential Improvements’ will require homeowners to undertake simple but cost effective mitigation measures whenever they undertake extensions or integrated conversions.
