The calculation methodology for determining energy performance in the BREEAM UK New Construction 2014 version has been revised for the 2018 version of the scheme. The methodology is based on compliance modelling and uses a triple metric approach that addresses energy demand, energy consumption and carbon dioxide emissions. The aim of using this approach is to enhance the ability of BREEAM to recognise and promote designs that minimise energy demand and consumption in buildings and then to reduce the carbon emissions resulting from that energy use. Guidance Note 39 sets out the new approach.
