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)
