Energy-Efficient Homes: What Brisbane Builders Recommend

With rising energy costs and growing environmental concerns, energy-efficient homes are becoming a priority for Australian homeowners. 

According to the Australian Government’s Department of Climate Change, Energy, the Environment and Water, residential buildings account for about 24% of the country’s electricity consumption. 

Additionally, the Queensland Government reports that energy-efficient homes can reduce household energy bills by up to 40% while significantly lowering carbon footprints.

Brisbane’s subtropical climate—characterised by hot, humid summers and mild winters—makes energy efficiency a crucial consideration for local builders. 

From smart design choices to advanced materials, here’s what Brisbane builders recommend for creating an energy-efficient home.

Top Energy-Efficient Home Recommendations from Brisbane Builders

1. Optimal Orientation and Design

Brisbane builders emphasise the importance of passive solar design—orienting the home to maximise natural light and airflow while minimising heat gain. Key strategies include:

• North-facing living areas to capture winter sun while avoiding harsh summer heat.

• Strategic window placement (e.g., fewer west-facing windows to reduce afternoon heat).

• Eaves and shading to block summer sun but allow winter sunlight.

2. High-Quality Insulation

Proper insulation helps maintain a stable indoor temperature, reducing reliance on heating and cooling. Builders recommend:

• Ceiling and wall insulation with high R-values (thermal resistance).

• Floor insulation, especially for raised homes, to prevent heat transfer.

• Reflective insulation in roofs to deflect radiant heat.

3. Energy-Efficient Windows and Glazing

Windows can be a major source of heat gain or loss. Solutions include:

• Double-glazed windows to improve thermal performance.

• Low-emissivity (Low-E) glass to reflect infrared heat.

• Tinted or thermally broken frames to reduce heat transfer.

4. Solar Panels and Renewable Energy

Queensland’s abundant sunshine makes solar power a smart investment. Builders suggest:

• 6.6kW solar systems (the most common residential size in Brisbane).

• Battery storage to maximise solar energy use.

• Solar hot water systems for additional energy savings.

5. Efficient Heating and Cooling Systems

Instead of relying solely on air conditioning, builders recommend:

• Split-system air conditioners with high energy-star ratings.

• Ceiling fans to improve airflow and reduce cooling costs.

• Zoned heating/cooling to only condition occupied spaces.

6. Water-Saving Fixtures

Energy efficiency isn’t just about electricity—water conservation also plays a role. Builders advise:

• Low-flow showerheads and taps to reduce hot water usage.

• Rainwater tanks for garden irrigation and non-potable uses.

• Drought-resistant landscaping to minimise water needs.

7. Sustainable Building Materials

Choosing eco-friendly materials improves efficiency and durability:

• Thermal mass materials (e.g., concrete, brick) to regulate temperature.

• Recycled or locally sourced materials to lower environmental impact.

• Light-coloured roofs to reflect heat (reducing cooling demand).

8. Smart Home Technology

Automation helps optimise energy use:

• Smart thermostats to adjust temperatures based on occupancy.

• Energy monitoring systems to track and reduce consumption.

• LED lighting with motion sensors for lower electricity use.
