The Unitary Plan also creates rules to ensure all new development containing five or more dwellings and large-scale office and industrial buildings are sustainably designed and built. This would mean that all large-scale office and industrial buildings would need to obtain a 5-star rating using the Green Star assessment tools developed by the New Zealand Green Building Council. This awards points for the use of sustainable building materials, high indoor air quality, energy and water efficiency and a wide range of other sustainable features. Any new development containing five or more dwellings would need to achieve a 6-star rating from the Homestar scheme, which also recognises compact design. The rules also set minimum standards for temperature and moisture control within the buildings.
