P69 Sustainability standards

  • Development must:
    • Achieve a BREEAM rating of ‘Excellent’ for non-residential development and non self-contained residential development over 500sqm; and
    • Achieve BREEAM rating of ‘Excellent’ in domestic refurbishment for conversion, extension and change of use of residential floorspace over 500sqm; and
    • Achieve BREEAM rating of ‘Excellent’ in non-domestic refurbishment for conversion, extension and change of use of non-residential floorspace over 500sqm; and
    • Reduce the risk of overheating, taking into account climate change predictions over the life time of the building, in accordance with prioritised measures set out in the following cooling hierarchy:
      • Reduce the amount of heat entering a building through the orientation, shading, albedo, fenestration, insulation and green roofs and walls; then
      • Minimise internal heat generation through energy efficient design; then
      • Manage the heat within the building through exposed internal thermal mass and high ceilings; then
      • Passive ventilation; then
      • Mechanical ventilation; then
      • Active cooling systems (ensuring they are the lowest carbon options)
