Recycled material should be used for the construction of streets, shared paths and other infrastructure where practicable.
# Other relevant clauses
# 15.01-2S Building design (opens new window)
Improve the energy performance of buildings through siting and design measures that encourage:
- Use of low embodied energy materials.
Encourage use of recycled and reusable materials in building construction and undertake adaptive reuse of buildings, where practical.
# 15.01-3S Subdivision design (opens new window)
Creating an urban structure that:
- Supports waste minimisation and increased resource recovery.
# Summary
# Better Practice
Awarded where lower upfront carbon materials and construction methods are identified and demonstrated using the Infrastructure Design Manual Sustainable Infrastructure Guidelines. This includes low-carbon choices for construction methodology, asphalt, concrete, aggregates, bedding sands, and pipe/conduit.
Examples include minimising earthworks, using recycled content in asphalt and concrete, and selecting pipes laid on recycled glass sand or made from recycled PVC or HDPE.
Note that this standard and 4.1a are the same standard. Achievement of this standard is considered Better Practice for large & very large subdivisions, and Excellence for small and medium subdivisions.
Examples of lower carbon construction and material solutions include:
- Minimising earthworks
- Minimising earth removed from or imported to site
- Using electric vehicles or equipment powered by renewables in lieu of diesel or petrol
- Reducing water use during the construction of the estate
- Asphalt alternatives to hot mix asphalt such as asphalt that contains Reclaimed Asphalt Pavement (RAP), is a cold, warm or foam mix, or uses substantial recycled content
- Concrete mixes that contain >10% Portland cement replacement products (eg slag, flyash, geopolymer)
- Recycled concrete or similar aggregates in asphalt, concrete, and/or pavement sub-grade or base course
- Concrete made from plants powered by significant renewable energy,
- Concrete made at plants that predominantly use recycled water.
- Pipe and conduit laid on crushed recycled glass sand or crushed brick dust
- Pipe and conduit that contains recycled PVC or comprises HDPE
