Lesson 2 – Design Objectives for Your Sustainable Natural Building Home

1. Conserve Water

Use water efficient appliances and fittings, such as 3-star (or more) shower-heads and water pressure-limiting devices, and include a rainwater tanks to supply water for use with gardens, toilets and laundry.


2. Heat and Cool Naturally (Passive Solar Design)

Good passive solar design allows your home to respond to its local climate through natural heating in winter and cooling in summer.


This incorporates:

  • Orientation and room zoning;
  • Capturing breezes for cross-ventilation;
  • Appropriate insulation;
  • Shading (e.g. sufficient eaves);
  • Building materials (lightweight construction/thermal mass);
  • Fixtures and finishes (e.g. skylights and window treatment).


3. Heat Water Efficiently

Install a solar, natural gas or electric heat pump hot water system to lower energy bills and reduce the single largest source of greenhouse emissions in the household.


4. Future Proof

Make the living area and at least one bedroom and toilet on ground level and readily accessible from the front boundary or car space to accommodate your changing housing needs as you get older.


5. Safe Floors

Design floors and showers to be step-free (hobless). Use floor surfaces that are slip resistant to guard against injuries.


6. Address the Street

An easy to read house number at the front of your property makes it easy to find. Good external lighting and separated driveway and pedestrian entries also makes it safer.


7. Casual Surveillance

For better security, design your home to have easy surveillance of play areas and the street, from the main living area and kitchen.


8. Long-term Maintenance

Reduce the repair and ongoing maintenance costs of your home by using low maintenance materials.


9. Indoor Air Quality

Avoid materials that contain volatile organic compounds, such as paints/finishes and adhesives, which can cause irritation and allergies, and impact poorly on your health.


10. Outdoor Living

Include permanently covered outdoor play and entertainment areas with a good relationship to indoor spaces to maximise your home’s access to favourable lifestyle.


11. Energy Efficiency

To ensure the efficient use of energy, to reduce total operating greenhouse emissions and to reduce energy peak demand.
