Eaglewood Farm, Mawson WA
Architecturally designed home that comfortably copes with extreme climatic conditions using sustainable technologies. The property generates 100% of its power and is self-sufficient in water.
Water Harvesting Systems
There are various tanks on the property collecting over 170,000 litres. There are also two dames which harvest rain water from the surrounding terrain. A grey water system designed from research undertaken by the owner, allows all grey water to be collected and is used in subterranean watering of the house gardens. There is no mains water connected. Solar powered pump is used for a bore.
Dry Toilet
The main toilet is dry called Ecosan which as the name suggests uses no water at all.
External Walls
Colorbond in "Dune" a light colour that reflects the heat and echoes the colour of the white gums on the hill above the house.
Internal Walls
Sisalation, 75ml recycled polystyrene, "aircell" insulation R2.5 over joists.
Roof
Colorbond in "Gasper" a light colour that reflects the heat. R3.5 Batts
Floor
Concrete slab used as thermal mass, it captures the winter sun through extensive north facing glazing.
Ventilation
The north orientation and rectangular shape of the building allows for deep sun penetration in winter; while all except the small east facing windows are shaded from the summer sun. Windows have been placed to allow cross ventilation and cooling night temperatures to bring down the internal temperatures. The high ceiling windows allow hot air to escape.
Power Generation
11.5 kW Solar power system, a generator is used for top up if and when needed.
Heating and Cooling
We don't anticipate needing any cooling air-con. Heating will be provided by a large wood fired slow combustion stove (wood collected on the property) which will also provide backup to the solar water heater in winter and be used as the main cooker during the winter months. Reversible fans will push warm air down to the living areas during winter and help circulate cool air in summer.
Special Features of the Farm
The 100 acre farm has been planned and developed using Permaculture design principles to produce a sustainable ecosystem for all its inhabitants, plants animals and humans. The aim is not so much to be totally self-sufficient but rather to live comfortably in harmony with our environment. There is a large orchard, six rotational raised garden beds plus two permanent raised beds for herbs, berries, asparagus and sweet potato. The rest of the farm is devoted to a Sandalwood plantation which is now four years old.
