Strategies for a 6 Star Rating
Achieving a 6 Star rating is the culmination of numerous design elements working together for the right climate zone. Here are key suggestions that can increase a home's star-rating:
- Orientation: Consider the home's location, and how it is orientated on the block. If you have not already chosen a block, your builder can help you choose one with an orientation that best suits your favourite home design.
- Room Placement: Place non-habitable rooms such as laundries and bathrooms to the east and west, bedrooms to the south and main living rooms such as dining and meals to the north.
- Size Matters: Keep size in mind, as the bigger the home, the more difficult it is to get higher star ratings.
- Minimise Wall Area: Purposefully minimise wall area by avoiding complex floor plans that can increase the external wall area.
- Window Strategy: Maximise north windows and minimise western, southern and eastern windows. Minimise window glazing on eastern and western windows.
- Shading: Plan proper shading for windows to control solar gain throughout the year.
- Heating Choice: Choose a flued gas heater instead of gas bayonet points for more efficient heating.
- Ceiling Insulation: Increase ceiling insulation to R4 or higher for maximum thermal protection.
- Wall Insulation: Consider wall cavity insulation, targeting east and west facing walls.
- Floor Treatments: Consider floor treatments such as floor tiles to living areas for thermal mass benefits.
- Ceiling Fans: Utilise ceiling fans for energy-efficient air circulation.
- Efficient Lighting: Choose energy efficient lighting, including use of sensors.
- Zoning: Identify areas that can be 'zoned' or closed off for more efficient heating and cooling.
- Sealing: Seal doors, windows, vents and exhaust fans. Self-sealing exhaust fans are an option.
- Glazing Options: Consider tinted or double-glazed windows for improved thermal performance.
- External Colours: Consider outside colour choices for both roof and walls to manage heat absorption.
Already Have a Block?
If you have already selected a block, your builder should offer a number of houses that are already 6-Star to suit the orientation and 'climate zone' of your existing block. We can help you optimise your design for your specific situation.
