The methodology for assessing energy within Ene 01 is unchanged, however the means of defining the baseline for assessing the performance of a new building in each UK territory has changed. In the 2011 version the England and Wales building regulation for energy (Part L 2010) was used to calibrate the Ene 01 translators in the UK scheme, and therefore all buildings assessed in the UK used the same baseline, regardless of location. In the BREEAM UK NC 2014 version, the energy related building regulation local to each UK territory is used to set respective baselines for the Ene 01 issue. BREEAM Guidance Note 12 provides a more in-depth explanation of the Ene 01 methodology.
