105 Energy efficiency
(1) Consent shall not be granted to development for the purpose of accessible housing, a dwelling house, a dual occupancy, a granny flat or multi-dwelling housing, or to development that increases the existing floor space of a dwelling house by more than 50 per cent, unless the buildings can achieve a 4 star NatHERS rating or alternative provisions for energy efficiency in accordance with the relevant part of the Council’s Better Living DCP.
(2) The design and location of development subject to subclause (1) should maximise energy efficiency and sunlight access for any adjoining residential buildings by ensuring that the development proposed to be carried out does not unreasonably obscure sunlight to habitable rooms or private open space of those adjoining residential buildings during winter months.
(3) The consent authority may require the preparation of shadow diagrams by a suitably qualified person to demonstrate whether adjoining dwellings and areas will be affected by the proposed development as required in subclause (2).
