Wrth ystyried yr achos dros y Mesur, gofynnodd Pwyllgor Deddfwriaethol y Cynulliad i Lywodraeth Cymru archwilio’r costau a’r manteision manwl cyn llunio rheoliadau o dan y Mesur. Mae’r Sefydliad Ymchwil Adeiladu (BRE) wedi cynnal dadansoddiad ar ran Llywodraeth Cymru o gost a budd y cynnig i gyflwyno systemau chwistrellu mewn eiddo preswyl newydd. Ceir crynodeb o’r gwaith hwn yn Atodiad A ac rwy’n cyhoeddi’r adroddiad hwn ar wefan Llywodraeth Cymru ac yn rhoi copi ohono yn Llyfrgell yr Aelodau heddiw.
In considering the case for the Measure, the Assembly’s Legislative Committee asked that the Welsh Government examine the detailed costs and benefits before making regulations under the Measure. A cost benefit analysis of the proposal to introduce sprinkler systems in new residential premises has been undertaken for the Welsh Government by the Building Research Establishment (BRE).  The summary of this work is at appendix A and I am today publishing this report on the WG website as well as placing a copy in the Members’ Library.
