Contributing features

• Insulation: extra care was taken when insulation was installed, and thickness of insulation is above minimum standard, therefore reducing the transfer of heat. Additional insulation installed in internal wet area walls and between floors.
• Draught seals: these have been installed on all windows and doors, and additional sealing was completed at the plaster stage, helping to minimise air leakage and uncomfortable draughts.
• Orientation and shading: the home’s main living areas face north. This enables the home to take advantage of the winter sun, keeping these rooms light and bright. Shading helps to keep this home cool in summer while still allowing access to plenty of natural light.
• Windows: high performance double-glazed low-E windows and sliding doors keep warm air in during winter and hot air out during summer, with up to 70% less heat loss. Double glazing also reduces external noise.
• Appliances: a heat recovery ventilation system provides the home with a continuous supply of fresh clean air. It exchanges stale inside air with fresh filtered air from outside via a heat exchanger, helping to save energy and money on heating and cooling.

Health

Promoting improved health and wellbeing

• Reduced likelihood of mould and mildew.
• A comfortable temperature inside the home promotes a better night’s sleep.
• Healthier air.

Contributing features

• Appliances: a heat recovery ventilation system provides this home with a continuous supply of fresh clean air, regulating humidity and reducing the risk of condensation and mould. Filtration helps to remove dust and pollution from the air, keeping your family healthy.

• Insulation: extra care was taken when insulation was installed and thickness of insulation is above minimum standard, therefore reducing the transfer of heat.

• Windows: double glazed windows reduce external noise.

Quality

Confidence that the house was constructed to meet the correct standards

• Minimal insulation gaps, with verified insulation coverage of above 98% in the walls, floors and ceilings.
• A verified air permeability rate of 7.7 m³/h/m² @ 50Pa making it less draughty than a minimum standards home.

Contributing features

• Extra sealing behind the walls: additional sealing treatments between the slab and frame, around the windows and fixed services for a more air-tight home.
• As-built verification: this assessment has been conducted and passed to confirm insulation coverage and air-tightness meets or exceeds required standards. For more information, read The ins and outs of as-built verification.

Savings

More money in your pocket and less impact on the environment

• Estimated annual dollar savings: $2,058.
• Estimated annual energy savings: 66,890 MJ.
• Estimated annual emissions savings: 7.39 tCO2-e.

• Heat Recovery Ventilation: provides a continuous supply of fresh tempered air helping to reduce reliance on heating and cooling
• Solar PV: enough solar PV to produce more energy than it uses over one year.

• Battery Storage: A 13.5 kWh battery enables the home to use more of the energy generated on-site by the solar PV system
• Energy-efficient appliances: all-electric energy-efficient appliances paired with solar PV ensures the offsets all emissions associated with its energy use.
