ART506 Dissertation 2019. Anthony Gwynne . 69 1.4 Net zero: The UK’s contribution to stopping global warming. Published by Committee on Climate Change. 2019. Committee on Climate Change recommends a new emissions target for the UK: net-zero greenhouse gases by 2050. This report led to (i) UK Government announcing net-zero greenhouse gases by 2050. (ii) Welsh Government announcing review of Approved Document L next year in line with announcements (Blick 2019) 1 . 5 Homes of Today for Tomorrow: Decarbonising Welsh Housing between 2020 and 2015. Stage 1: Scoping review. Stage 2: Exploring the potential of the Welsh housing stock to meet 2050 decarbonising targets . Published by Cardiff University. Green et al. 2019. Cardiff University investigated the decarbonisation of Welsh housing by 2050 with massive improvements to the existing housing stock. It identified: 14 different dwelling types including four dwelling types pre 1919; 84% of the housing stock has already been built; much of it is far from efficient. The report fails to identify special measures for the upgrading of solid wall houses built before 1919 using vapour permeable materials. The report proposes no distinction between performance standards for the retrofit of existing homes and new build homes. 2. Concept design 2.1 Energy performance of heritage buildings: predictions and performance . Published by BRE. 2011. The BRE investigated improving thermal performance in traditional buildings. BRE concluded that national guidelines are required, including: (i) how buildings are intended to function and (ii) which interventions are appropriate for a construction. 2.2 Responsible Retrofit of Traditional Buildings. Published by Sustainable Traditional Buildings Alliance (STBA). 2012. The STBA investigated concerns raised into the application of retrofit measures into the UK traditional building stock, including those incorporated into the Green Deal. The STBA key findings included: ‘ There is a lack of understanding of traditional building performance in industry and policy, and a lack of connection between good research, certification process, guidance and practice’. 2.3 BS 7913:2013. Guide to the conservation of historic buildings . Published by British Standards Institution (BSI). 2013 . BS 7913 is a standard of good practice for works to older, traditional buildings. The standard is intended for those who own, use, occupy and manage historic buildings, the professional team's contractors and others employed to work on their behalf, and can be used by decision makers and funders. Although BS 7913 covers the conservation process from drivers of change to post project review it does not make any reference to the Building Regulations or Approved Documents. It does not provide any guidance on solid walled construction or use of vapour permeable materials. A major problem with BS 7913 is the public must pay to use it, putting it out of the reach of most people who will not be able to use it (and likely to default to the Building Regulations and Approved Documents for guidance). 2.4 Energy efficiency in old buildings . Published by SPAB. 2014. Understanding old buildings – SPAB is at the forefront of research into the energy efficiency of old buildings. SPAB concluded that natural (vapour permeable) insulation and other traditional materials are performing best in old buildings (constructed of vapour permeable materials). 2.5 Solid wall heat losses and the potential for energy saving . Published by Department of Energy and Climate Change (DECC), 2015. DECC commissioned BRE to undertake research to improve understanding of the performance of solid wall properties in the UK. BRE concluded that traditional buildings were built to be breathable and so installing impermeable insulation materials and vapour barriers increase the likelihood of moisture problems.
