Sustainable Living

Climate Context

  • Round Mountain has a humid subtropical climate with:
    • Hot, humid summers
    • Mild winters
    • Year-round sunshine
    • Climate-responsive design improves comfort and reduces household running costs.

House Location

  • Identify north, east, south, and west on your lot before designing.
  • Understanding orientation helps optimise sunlight and cooling breezes.
  • Climate-responsive homes are achievable on all lot orientations.

House Design

  • Position living areas on the north and east sides with large windows for best light and temperature control.
  • Use large windows and doors connected to covered outdoor areas to enhance airflow and extend living spaces.
  • Locate non-habitable rooms (bathrooms, laundry, garage) on the south and west sides to:
  • Reduce afternoon heat gain
  • Shield the home from cold south-west winds
  • 450 mm minimum eaves are required on habitable rooms, especially to western and southern sides.
  • Increased setbacks between homes can improve airflow and garden space.
  • Open-plan layouts encourage natural cross-ventilation.
  • Ceiling fans improve indoor and outdoor air circulation.
  • Whirlybirds help remove heat from roof spaces in summer.

Building Materials

  • Lighter colours reflect heat and help keep homes cooler.
  • Darker colours absorb heat and increase indoor temperatures.
  • Lightweight materials (e.g. timber, fibre cement) can improve comfort compared to traditional brick and tile construction.
  • Contain recycled or renewable content.
  • Are sourced locally where possible to reduce transportation impacts.
  • Have a lower environmental impact during manufacturing.
  • Are durable, easy to maintain and built to last.
  • Can be reused or recycled at the end of their life.
  • Have recognised environmental certifications from independent organisations.
  • Consider using low-VOC paints, adhesives, and sealants to help improve indoor air quality within your home.

Landscaping

  • Use trees with large canopies to:
  • Provide summer shade
  • Reduce glare
  • Tree species and placement should support cooling breezes.

Water Tanks

  • Rainwater tanks are encouraged and:
  • Harvest rainwater
  • Reduce stormwater runoff
  • Lower reliance on mains water
  • Reduce water bills
  • Suitable for non-potable uses, including garden irrigation.

Water Efficient Fixtures

  • Showerheads with a flow rate of less than 7.5 litres per minute.
  • Bathroom, kitchen and laundry taps with a flow rate of less than 6 litres per minute.
  • Dishwashers that use 14 litres of water or less per cycle.
  • Washing machines that use 90 litres of water or less per cycle.

Solar Panels

  • Solar panels help:
  • Lower electricity costs
  • Reduce carbon footprint
  • Solar batteries provide energy independence and reduce reliance on the electricity grid.

Energy-Efficient Appliances

  • Energy-efficient appliances:
  • Reduce household energy bills
  • Lower greenhouse gas emissions
  • Minimise environmental impact
