Ecology
Zone 1: Frequent visits – Kitchen garden, herbs, salad crops, small fruits, compost bin
Zone 2: Semi-cultivated – Orchards, vines, pumpkins, sweet potatoes, grapes
Zone 3: Occasional visits – Low-maintenance fruit and nut trees
Zone 4: Wild area – Native ecosystems, trees, plants, bush food, no intervention
Removing non-native and exotic vegetation, retaining native melaleuca trees, and planting new native trees, including dense shrubs, nectar-rich plants, and larger rocks. No petrochemical fertilizers or pesticides will be used.
Energy

Firstrate 5 was used to analyze the baseline energy use for heating and cooling. Adjustments were made (see right) to achieve a 9.1 star rating.

Material

Embodied emissions analysis of the baseline design informed efforts to reduce emissions and energy through structural redesign and the use of mud bricks. While minimizing emissions was prioritized, some materials with higher embodied energy and emissions, such as plywood, were chosen over alternatives like paint, plaster, and fiberglass insulation.

Water
Household water usage was calculated from three factors: individual, household, and summer use. Tank, gutter size, and downpipe count were determined based on rainfall. Contributions from greywater and rainwater were subtracted from the annual water demand, reducing reliance on potable water. As required by the EPA, drinking water cannot be sourced from greywater treatment systems.
