As with the other net zero policies for buildings in this consultation, I'm pleased to see reference to LETI and Passivhaus, but this policy direction needs to set out clearly when each standard should be required as if left to the applicant, it will just not happen.
The AECB CarbonLite Retrofit Standard is better for traditional buildings and also considers many more retrofit risks. The STBA Guidance Wheel provides the opportunity to research the interactions between different options of retrofit.
Alternatively, PAS 2035 (for domestic buildings) & Trustmark could be required as it has consumer protection and QA embedded.
