Technical standards for new buildings came into effect on 30th November 2006. These are set out in Technical Booklet F1 for dwellings and Technical Booklet F2 for all other buildings and can be downloaded from

www.buildingregulationsni.gov.uk.

The building complies with the regulations if it satisfies criteria very similar to those listed for England and Wales above.

Requirements for existing buildings: Implementation of Articles 4&6 England and Wales

The requirements for existing buildings came into force in April 2006 – see Approved Documents ADL1B and ADL2B at

http://www.planningportal.gov.uk/england/professionals/en/1115314110 382.html.

When work is carried out on existing buildings, all such work is expected to meet minimum energy efficiency standards defined at the elemental level. For certain types of major improvement works in buildings with floor areas over 1,000m2 where the work has the potential to increase energy intensity (e.g. extending the building or installing air conditioning), there is a further requirement for additional improvements to energy efficiency, provided these are technically, functionally and economically feasible. These are known as consequential improvements.
