Built using standard materials and construction techniques, the Sustainable Mandurah Home will offer flexible accommodation featuring three bedrooms, two living areas and an activity area ideal for use as a study or fourth bedroom.

The passive solar design will ensure rooms are a pleasant temperature all year round – reaching no more than 28C in summer months and dropping no lower than 18C in winter – without the aid of artificial heating or cooling.

Other design features include:

Design and orientation

• Orienting the house on the block so that living areas face north to encourage the penetration of winter sun
  
• Minimal glazing to the east and west to limit the entry of harsh morning and afternoon summer sun
  
• Careful use of shade to deflect heat in the summer without compromising the penetration of sun during the winter
  
• Windows positioned to permit maximum cross ventilation, capturing cooling summer breezes
  
• Solar louvres angled to deflect heat in the summer and allow penetration of sun in the winter
  
• Systematic insulation in all relevant wall and roof/ceiling to help keep temperatures stable
  
• Use of trees and plants to protect the home from summer heat and cold winter winds
  
• Ecovents to remove excess heat in the roof space

Energy

• Photovoltaic cells to capture and convert the sun’s energy into electricity – a 1.5kW grid-connected 10 panel system will provide the electricity needs of the home. A digital display will show data such as energy generated and greenhouse gas emissions saved
  
• A gas-boosted solar hot water system providing all the family’s hot water needs
  
• A selection of energy efficient lighting and appliances
  

Water

• Water-wise landscaping
  
• A grey water reuse and storm water collection system that collects grey water from sinks, baths and showers and re-directs it for garden irrigation
  
• A selection of water-efficient appliances, including AAA rated taps and showerheads
  

Materials and furnishings

• Appropriate selection and location of building materials to provide the thermal mass required to store heat from the sun
  
• Materials sourced from sustainable sources wherever possible and economically feasible
  
• Low allergenic and low toxicity materials for improved indoor air quality
  

Waste

• Conveniently-located containers to encourage recycling within the home
  
• Composting facilities to recycle kitchen and garden waste
