New Part L Requirements 2013

09 April 2014 on Uncategorized by Rebecca Cook

The new Part L requirements 2013 were implemented on the 6th April 2014. It will mean a further 6% reduction in carbon dioxide emissions in new houses over Part LA 2010, and the introduction of the FEE calculation as part of building regulations (FEE is already calculated in Ene 2 of the Code for Sustainable Homes Assessments). FEE, short for Fabric Energy Efficiency calculates the energy performance of the fabric of the dwelling and the heat losses. This will mean less reliance on renewable technologies in SAP calculations, with greater emphasis on higher levels of insulation and airtightness. The FEE target for a detached house is 46 kWh/m2/year, compared with Passivhaus target of 15 kWh/m2/year, there is still obvious room for improvement.

We believe in a fabric first approach and welcome these changes to Part L.
