Published by Bristol City Council. 2015. This guidance commissioned by Bristol City Council is for people living in and people working on solid walled houses in Bristol built before 1919. It provides practical guidance and sketches on how to retrofit solid walled buildings including the use of vapour permeable insulations. The guidance concluded that responsible retrofit is required when improving the comfort and energy efficiency of older solid walled buildings to avoid inappropriate and potentially damaging (non vapour permeable) measures being installed. 4.3 Retrofit insulation systems for old buildings. Published by Ty- Mawr. 2019. Ty-Mawr have developed several vapour permeable insulation systems and finishes for roofs, solid walls and ground floors in compliance with the Building Regulations. Nigel Gervis -technical director of Ty-Mawr has through practical research concluded that the thermal insulation requirements of the Building Regulations for solid wall insulation is unrealistic and problematic as it causes cold spots behind internal wall insulation, traps water and increases the risk of condensation and mould growth. Instead of a U-value of 0.3 for upgrading existing walls he increased the U-value to 0.7 and confirmed they have experienced less problems of trapped water, condensation and mould growth. In his opinion, design flexibility would allow higher insulation levels in the roof and floor to offset the lesser wall insulation levels. 5 Works phase No relevant documents. 6 Post project reviews 6.1 100 unintended consequences of policies to improve the energy efficiency of the UK housing stock. Published by UCL Discovery. 2014 The authors undertook a scoping review of the UK Government policies to improve the energy efficiency the UK housing stock. They identified more than 100 un- intended consequences impacting building fabric, population health and the environment, thus high- lighting the urgent need for government and society to reconsider its approach. The authors concluded a pressing need for the involvement of multiple stakeholders from a variety of disciplines to investigate the issues raised in the report holistically. Key issues could be highlighted, and regulatory measures framed to achieve UK Government policy goals without unduly jeopardising general health, well-being and the damage to building fabric, contents and the environment that is otherwise likely to occur. 6.2 Solid Wall Insulation: Unlocking Demand and Driving Up Standards. A report to the Green Construction Board and UK Government by the Chief Construction Advisor. Published by HM Government. 2015. The Green Construction Board commissioned the Chief Construction Advisor to the UK Government to investigate: - why current demand for solid wall insulation is depressed and - why solid wall insulation has a poor reputation of inadequate installation and poor workmanship. The Chief Construction Advisor to the UK Government grouped his findings into several themes, but the key findings for this dissertation are: -Proper design is frequently absent -There is an unacceptable risk of unintended consequences including damp, mould, poor air quality and poor building performance -Some standards are insufficiently detailed in respect of solid wall insulation and may
