This policy will set the levels of energy use that will be allowed for new development and the specific requirement regarding the energy needs of new buildings. Residential developments of 150 homes or more and non-residential development of 1,000 m2 or more should calculate whole life carbon emissions through a nationally recognised Whole Life Carbon Assessment and demonstrate actions to reduce life-cycle carbon emissions. This should include reducing emissions associated with construction plant. Gladman are supportive of attempts to reduce carbon, however new buildings and residential developments will be built in accordance with the Building Regulations at the time of their construction.
