|Following on from the Part L consultation in England, the Welsh Government has initiated a consultation that sets out the plans to improve the energy efficiency requirements for new homes in Wales in 2020.
Like in England, the proposals for new dwellings in Wales includes two options. Option 1 – favoured by the Welsh Government – would be expected to deliver a 37% reduction in CO2 emissions compared to current standards (based on a semi-detached home), whereas option 2 -utilising mechanical ventilation with heat recovery – targets a 56% reduction.
By comparison, the corresponding proposals for new dwellings in England include option 1 based on a high performance 'fabric first' approach and estimated to bring a 20% reduction in CO2 emissions compared to current standards. The Government's preferred option 2 for England is based on a less ambitious fabric but with the introduction of renewable technologies, aiming for a 31% reduction.
While we wait to hear about proposals for changes to the Technical Handbooks in Scotland, we should be prepared for a Part L 'Battle of Britain' over which country is the most ambitious in terms of energy efficiency and reducing carbon emissions. This could be important for the glass and glazing industry, particularly for companies selling products into the different countries of the UK, where the required performance of windows may be different.
