A public consultation has commenced on a review of Building Regulations, Technical Guidance Document L (Conservation of Fuel and Energy) Dwellings and Technical Guidance Document F (Ventilation).

 

Calculations in 2023 resulted in advanced cost optimal levels for major renovations to dwellings. In accordance with the EPBD, where more than 25% of the surface area of the building envelope undergoes renovation, the energy performance of the whole building should be improved to cost-optimal level in so far as this is technically, functionally and economically feasible.

 

In order to achieve the 2023 Cost Optimal requirement for major renovations it is intended to implement the performance requirements of a BER of "A3" or cost optimal equivalent works for major renovations to existing dwellings through amendments to TGD L (Conservation of Fuel and Energy) Dwellings and TGD F (Ventilation)
