False readings may occur, for instance, because of surface deposits or past chemical treatments. Appendix L: Transcript of Interview with Research Fellow at Cardiff University (RF) Place and date of interview: Cardiff University on 18 Nov 2019 Subject- report on: Homes of Today for Tomorrow Stage 1 & Stage 2: Questions. Questions were asked by Anthony Gwynne (AG) and answered by the Research Fellow (RF) Question 1. AG- How may pre 1919 homes equates to 23%? Answer: RF - Total Welsh housing stock is 1.4m, 23% was built before 1919 which equates to 322,000. Cadw confirmed there are 30, 000 listed building in Wales (cadw.gov.wales). Question 2 . AG- Does the discussions on building fabric for example wall upgrades etc consider the use or vapour or non-vapour permeable materials on pre 1919 solid wall buildings. Answer : RF - No. AG made the point that this is concerning as it states in the executive summary that ‘ there should be no distinction between performance standards for retrofit and newbuild’. I explained that Non-vapour permeable materials can trap moisture and cause deterioration of the building fabric. Question 3 . AG- Does net zero carbon emissions by 2050 apply to new and existing buildings? I raise this as an email mail I received from Building Control Technical manager for Wales (2019) states the review is of new dwellings only? Answer : RF - It applies to both new and existing dwellings. Question 4 . AG- How are the Welsh Government are going to achieve net zero carbon emissions by 2050? Answer : RF This is included in the stage 2 document, and an important aspect is exploring the impact of cleaner energy supply (Paragraph 4.3). This is demonstrated in Appendix A as the impact on carbon emissions and costed actions on 14 different dwelling types using scenario 1 and 2 to achieve 40-60% clean energy supply (scenario 3 was not considered possible and not included).
