As the summer sun beats down, many homeowners find themselves in a constant battle against the searing heat. One of the most effective ways to maintain a comfortable temperature in your home during the hot weather is by strategically opening and closing your windows. But when exactly should you keep them open or closed? Let’s dive into this cool topic and explore some top tips for managing your home’s temperature during the summer months.
The magic number: 23°C
While there’s no one-size-fits-all approach, a good rule of thumb is to close your windows when the outside temperature reaches around 23°C. At this point, the air outside is likely warmer than the air inside your home. Keeping windows shut prevents hot air from entering and helps maintain a cooler indoor environment.
Location, Location, Location
When it comes to window management, the position of your windows also plays a crucial role:
South-facing windows: These windows receive the brunt of the sun’s heat throughout the day. During peak sun hours (typically 11am to 4pm), it’s best to keep south-facing windows closed and blinds shut to block out direct sunlight and prevent heat build-up.
North-facing windows: These windows receive less direct sunlight, making them ideal for capturing cooler breezes. Keep north-facing windows open during the day, especially in the evenings, to encourage airflow and natural ventilation.
East-facing windows: Enjoy the refreshing morning sun by opening east-facing windows in the early hours. However, consider closing them during the afternoon to prevent the heat from intensifying.
West-facing windows: Similar to south-facing windows, west-facing windows receive strong afternoon sun. Close them and shut blinds during the hottest part of the day.
Timing is everything
To maximise the cooling effect in your home, it’s crucial to pay attention to the time of day. The best times to keep your windows open are typically in the early morning and late evening when the outdoor air is cooler. Aim to open your windows before 9am and after 5pm to let in that refreshing, cool air.
During these cooler periods, creating a cross breeze can make a world of difference. Open windows on opposite sides of your home to encourage air flow, a cool breeze and natural ventilation. This simple technique can significantly lower the overall temperature of your home without relying on energy-intensive air conditioning.
Shut out the sun
When the temperature rises and you’ve closed your windows, don’t forget about your blinds and curtains. Keeping these shut during the hottest parts of the day is a great way to block out direct sunlight and prevent warm air and excess heat from building up inside. You may have noticed when you go abroad on holiday that homes in warmer climates often have their blinds or shutters closed during the day – there’s a good reason for this age-old practice!
The power of solar control glass
For those looking to take their home cooling strategy to the next level, consider installing windows with solar control glass. This innovative glazing reflects a significant portion of the sun’s rays while still allowing natural light to filter through. It’s an excellent way to maintain a comfortable indoor temperature without relying solely on opening and closing windows or cranking up the air conditioning.
Listen to your home and stay cool
While these guidelines are helpful, it’s essential to pay attention to the unique characteristics of your home to make sure you let cooler air in. Factors like insulation, orientation, and the surrounding landscape can all affect how quickly your house heats up or cools down. On a hot day, if you notice that it feels cooler inside than outside, keep those windows closed to preserve the pleasant indoor temperature and make your home cooler.
Remember, managing your windows is just one piece of the puzzle when it comes to keeping your home cool in summer. Combining this strategy with other methods like using fans and opening doors, you can make your home a comfortable oasis even during a heatwave.
