Home Energy Model: Future Homes Standard assessment: technical documentation
Summary
DESNZ publishes technical documentation for the Home Energy Model methodology that will assess buildings against the Future Homes Standard. The documents provide implementation detail for building energy performance calculations. This is part of ongoing model development for housing energy efficiency standards.
Why it matters
This is redistributive policy that treats symptoms of expensive energy rather than addressing supply or market structure. Building standards may reduce demand but do not fix the fundamental constraints on electricity supply or grid capacity.
