Energy-saving tips for Geelong homes: better performance, lower bills

Living in Geelong and the surrounding regions means dealing with warm summers, cool winters, and everything in between. Whether you are building a new home or improving an existing one, making smart energy decisions can reduce your power bills, increase comfort, and lessen your environmental impact.

These energy saving tips Geelong homeowners can implement will help create homes that perform better in all conditions.

At Conscious Construction Co., we specialise in high-performance custom builds that suit Geelong’s climate and lifestyle. These practical tips are based on what we apply in our own work.

1. Prioritise insulation and airtightness

Insulation and airtight construction are the foundations of an efficient home. Without them, heating and cooling systems work harder than necessary.

• Improve insulation in walls, ceilings, and under floors to reduce heat loss in winter and heat gain in summer.

• Seal any air leaks around windows, doors, and vents to avoid drafts and energy waste.

• Install high-performance glazing to maintain a comfortable indoor temperature year-round.

If you are planning a renovation or a new build, choose a builder trained in Passive House principles. These homes stay comfortable with far less energy input.

2. Make use of Geelong’s natural sunlight

Geelong’s climate provides excellent opportunities for passive solar design. Good orientation and shading can help regulate indoor temperatures without extra energy use.

• In winter, open blinds on north-facing windows to let in the sun.

• In summer, use eaves or shade systems to block direct heat.

• Install skylights or solar tubes in dark spaces to reduce the need for artificial lighting.

If building from scratch, aim for living areas to face north and use thermal mass to store heat.

3. Choose efficient heating and cooling systems

Heating and cooling account for a large portion of household energy use. Selecting efficient systems can make a noticeable difference.

• Opt for reverse-cycle air conditioners or heat pumps instead of ducted gas.

• Set your thermostat to 18 to 20 degrees in winter and 24 to 26 in summer.

• Use ceiling fans to circulate air rather than relying solely on air conditioning.

Close off unused rooms to avoid heating or cooling spaces you do not need.

4. Install solar power and battery storage

Solar power systems help reduce energy bills and provide long-term savings. With Victorian rebates available, they are more accessible than ever.

• Install rooftop solar panels to generate your own electricity.

• Add a battery system to store excess power for use at night.

• Combine solar with energy-efficient appliances to reduce reliance on the grid.

5. Upgrade your lighting and appliances

Outdated appliances and lighting often waste more energy than you realise. Efficient replacements save money over time.

• Replace halogen globes with LED lighting throughout your home.

• Choose high-star-rated appliances, especially for fridges, dishwashers, and washing machines.

• Use power boards with on-off switches to eliminate standby energy use.

Always check the energy rating before purchasing new appliances.

6. Reduce hot water energy use

Hot water systems are one of the biggest energy consumers in the home. A few changes can lead to significant savings.

• Install a solar or heat pump hot water system.

• Use water-efficient showerheads to reduce hot water usage.

• Wash clothes in cold water when possible.

Keep your hot water system set to no more than 60 degrees to avoid unnecessary energy use.

7. Design a high-performance home

If you are building or renovating, thoughtful design can reduce long-term costs while improving daily comfort.

• Work with a builder who understands Passive House standards and local conditions.

• Invest in high-quality windows, proper shading, and continuous insulation.

• Select low-impact materials that improve indoor comfort and reduce heat loss.

Homes designed for performance are easier to live in and cheaper to run.
