As the summer heat seems to be sticking around, keeping your home comfortable can be a challenge. While air conditioning helps, there are smarter ways to keep your house cool while lowering energy costs. By improving ventilation, using skylights, and making small changes around your home, you can stay cool naturally.

1. Use Skylights for Natural Ventilation

Skylights don’t just add natural light to your home—they can also improve air flow. Ventilated skylights allow warm air to escape, while cooler air enters from lower windows and doors. This reduces heat transfer, keeping your rooms cooler without overusing your air conditioner.

2. Block Out Heat with Window Coverings

Direct sunlight through windows and skylights can increase indoor temperatures. Using window coverings like blinds, curtains, or reflective films helps shade windows and prevent UV rays from heating your home. For west-facing windows, external awnings or pergolas can further reduce heat.

3. Improve Roof Ventilation to Reduce Heat Build-Up

A poorly ventilated roof can trap hot air, making your home feel warmer. Installing roof vents or solar-powered exhaust fans removes trapped heat, reducing the strain on your air conditioning. A well-ventilated roof also extends the life of your roofing materials by preventing excess heat damage.

4. Maximise Airflow with Fans and Cross Ventilation

Using ceiling fans alongside open windows creates a cooling effect by helping push air through your home. Position fans to draw in a cool breeze, and open multiple windows to create cross ventilation. Keeping doors open between rooms also improves air flow, reducing the need for artificial cooling.

5. Reduce Indoor Heat Sources

Everyday appliances contribute to indoor heat. On hot days, limit oven use and opt for outdoor cooking or fresh, no-cook meals. Switch to LED lighting to minimise heat output, and replace heavy bedding with breathable fabrics like cotton sheets for a cooler sleep. Taking a cold shower before bed also helps you feel cooler and more comfortable.
