Yes

Energy Star Rating

8.8 Star NatHERS + 10 Star Residential Efficiency Scorecard

Renewable energy used:

Solar PV

Size of PV system

6.6kW

Size of battery

11kW

Energy efficiency:

Draft proofing, LED lights, EE appliances, 5 point door seal/locks.

Passive heating cooling:

East west build with maximum north-facing windows. The Butterfly roof allows for maximum winter sun ingress. Deep eaves protect windows in summer. Concrete thermal mass to absorb winter sun heat during the day and dissipate heat overnight.
Crossflow ventilation (celestial window and double sash) to regulate temperature all year round.
Cool cupboard to store wines, produce and preservatives.
Deciduous plants to regulate shade in Summer & Winter.
Large gardens to reduce heat absorption of outside surfaces

Active heating cooling:

Energy efficient reverse cycle AC in living area and master bedroom.
Undertile heating in ensuite.
Ceiling fans in living areas and bedrooms.

Water heating:

Electric heat pump run off solar

ABOVE GROUND RAINWATER STORAGE:

7000 litre slimline colorbond tank.

WATER HARVESTING AND SAVING:

Butterfly roof directs 93% of rain to a single gutter and water tank.
Rainwater tank supplies water to all toilets, laundry and garden.
Low flow taps and shower heads.
Taps in master ensuite are Australian made with 5 star Wels rating. The shower is 3 star. All other taps and toilets are 4 or 5 star.
Wicking garden beds.
Dry creek bed.
Water wise native garden
No concrete except for a short drive-way all other external areas are permeable.

ENERGY EFFICIENT LIGHTING:

Long life LED surface mounted wall and down lights.
Effective use of reflecting light on walls and ceiling to maximise light from a single source.
Light switches are zoned to small areas so that only the required lighting is turned on.

WINDOW PROTECTION:

Large eaves.
Cellular blind in west facing window.

CAR CHARGING

We are set up for a separate 3 phase power to the garage for a fast car charger, but we installed a single 15 amp powerpoint as this meets the maximum charge for our Outlander PHEV being 3 .5 hours. A standard 10 amp power point would take 7 hours to charge. We charge off the solar so fast charging is preferable.

Healthy home features

Low VOC paints and finishes.
No treated pine frame unless regulated.
No carpet.
Minimal air changes with good draft sealing, with ventilation as required
Natural light to all rooms, negating daytime artificial lighting.
Consistent internal ambient temperature

COST ESTIMATE OF SUSTAINABLE HOME/FEATURES:

A smart design and an environmentally aware builder will reduce the cost of sustainable features. Like solar you pay forward for some costs to save both the environment and your pocket in the future.

COST SAVINGS PA:

Lower electricity used (eg heat pump / LED lights etc.), no gas and charge car from solar. Approx $2750

GARDEN / OUTDOORS:

Large water wise native garden
Gravel paths for increased water permeability and reduced heat absorption.
Concrete wicking beds.
Fruit trees.
Fish pond

WASTE REDUCTION PRACTICES:

Composting - No green bin
Worm farm.
Tank water.
All garden beds mulched
All household waste sorted.
