These are simple things that can be incorporated into practically any design.
They often go unnoticed.
- Five-star appliances and equipment
- Australian-made products
- Plantation softwoods for structural timbers
- "Green" power from electricity supplier
- Natural gas appliances and heating rather than electrical
- Compact fluorescent and LED low energy light globes
- Consideration of solar orientation, natural ventilation, and natural daylighting
- Deciduous shading from summer sun
- Extra insulation especially in the ceiling/roof
- 5+ star rating House Energy Rating
- Weather seals at doors and windows
- Solar hot water
- Composting and recycling systems
- Water-saving taps, shower heads etc
- Maximise natural porous ground (i.e. minimise paving and roof area)
- Refrigerator kept in an unheated room
These are a bit more involved than level 1 items, and the building will take on
a bit more of a "green" feeling.
- Recycled timbers - especially cabinets, joinery items, and floor boards
- "Natural" finishes rather than standard paints and polyurethane
- Internal thermal mass in walls and/or floors
- Double-glazed windows
- Tank water collected from roof to service all or part of water usage
- Grey-water reused in garden (i.e. from bath or laundry) STCA
- Recycled materials (i.e. doors, brick paving etc.)
These are more expensive and involved. In a rural setting, they may be imperative.
In an urban setting, they might be considered the "glamour items" of green building.
- Grid-interactive solar power system
- On-site sewage treatment plant
