Energy Coach - May
Cold weather approaching! It’s time to get prepared.

As the Australian autumn deepens in May, cooler temperatures and shorter days bring new challenges and opportunities for home energy efficiency. With winter on the horizon, preparing your home now can lead to significant energy and cost savings. In this guide, we explore practical and effective tips to enhance your home’s energy efficiency during this transitional month, ensuring your home remains comfortable, environmentally friendly, and economically run.

Preparing for the Chill: Immediate Steps

1. Fine-Tune Your Heating System

Before the cold fully sets in, ensure your heating system is in top shape. Service your furnace, heat pump, or boiler to improve efficiency and prevent mid-winter failures. Replace filters or clean reusable ones to ensure optimal airflow and efficiency.

2. Embrace Smart Thermostat Technology

Installing a smart thermostat can lead to significant energy savings. These devices optimize heating by adjusting temperatures based on your daily schedule and weather conditions, ensuring you use energy only when necessary. Set your thermostat to lower temperatures when you are asleep or away from home.

Smart home cooling systems offer precise control and improved efficiency. These systems not only cool homes more effectively but also adapt to user habits and preferences, leading to smarter energy use.

3. Draught-Proof Your Home

Draughts can increase your heating costs substantially. Use weather-stripping and caulk to seal gaps around doors, windows, and any other areas where cold air might enter. This simple measure can prevent heat loss and reduce your heating needs.

One of the quickest and easiest ways to improve the thermal efficiency of your home is to stop drafts from around your door

4. Optimise Window Use

Thermal curtains can be a great investment for keeping the warmth in and the cold out, especially at night. During the day, open curtains on north-facing windows to allow natural sunlight to heat your home,to 60°C to ensure safety while and close them as soon as it gets dark to preserve the warmth.

Its Curtains for Cold
Curtains are more than cosmetic - they can minimise heat transfer through your windows, keeping your home more comfortable year round.

5. Adjust Your Water Heating

Water heating accounts for a significant portion of energy costs in Australian homes. Set your water heater to 60°C to ensure safety while optimizing energy use. Consider wrapping older models with an insulating blanket to reduce heat loss and lowering the temperature setting when you’re away for extended periods.

Hot Water Systems
Hot water is one of the most important household appliances. Here’s how to navigate the complexities of hot water systems, focusing on energy efficiency and safety.

Long-term Investments for Year-round Savings

1. Upgrade to Energy-Efficient Windows

If your home has older, single-pane windows, upgrading to double-glazed or energy-efficient windows can significantly reduce heat loss during the cooler months and heat gain during summer. This upgrade can improve your home’s comfort and reduce heating and cooling costs.

Although the initial investment for double-glazed or energy-efficient windows can be significant, the long-term savings and comfort is worth it.

2. Insulate Your Home

Proper insulation is one of the most effective ways to maintain your home's temperature. Check and upgrade the insulation in your attic, walls, and floors. This will keep your home warmer in the winter and cooler in the summer, reducing the need for heating and cooling.

Insulation is the single most important thing for minimising energy consumption in your home. Here’s everything you need to know.

3. Consider Solar Panel Installation

May is a good month to plan for solar panel installation as the days start to shorten. Solar panels can provide significant energy savings by generating your own electricity and leveraging government rebates and feed-in tariffs.

4. Install a Heat Pump System

Heat pumps are highly efficient systems that can heat and cool your home. They work most efficiently in moderately cold or warm climates, making them an excellent choice for many parts of Australia.

5. Regular Maintenance

Establish a routine for checking and maintaining your home’s energy systems. This includes cleaning solar panels, servicing your HVAC system, and ensuring your home’s exterior is in good condition to handle the winter months.

May Energy Efficiency Checklist

  • Service heating systems before winter begins.
  • Install or program a smart thermostat to reduce energy usage.
  • Seal drafts around windows and doors to keep warmth in.
  • Use thermal curtains to add an extra layer of insulation.
  • Check and adjust your water heater to ensure it’s set at a safe and efficient temperature.

Sustainability and Cost Efficiency

Focusing on energy efficiency not only helps in reducing utility bills but also contributes to a sustainable environment. By implementing these measures, homeowners can play a crucial part in reducing carbon footprints and promoting a healthier planet.

Community and Government Incentives

Explore community programs and government incentives available for energy-efficient upgrades in your area. Many local governments offer rebates for installing insulation, energy-efficient windows, and renewable energy systems.


May is a pivotal month for preparing your Australian home for the cooler weather ahead. By taking proactive steps now, you can ensure your home is warm, comfortable, and energy-efficient throughout the winter. Start with immediate, simple actions and plan for the longer-term investments that will provide continuous benefits.
