6 Energy-Saving Tips You Need to Know to Keep Your House Cool
How do you keep your house cool without running up your electricity bill? Here are our 6 practical electricity-saving tips.
The summer months of May through August can be extremely hot, especially if you’re living in tropical countries where it seems to be summer year-round. This season is the best time to enjoy outdoor BBQs with your family, beach trips with friends, and camping somewhere outside the city. However, this time of year could also be very unbearable when you stay indoors—with all the heat, dust, and humid air circulating your house during the day. And you don’t want to keep your AC running for long periods!
To keep your house cool without running up your electric bills, here are 6 energy-saving tips you can try:
Block the sun out
This one’s obvious; however, most of us still let the sun stream inside our house through our windows. To keep our house cool, we must keep curtains closed, especially during the hottest time of the day. If your curtains are not thick enough to block sunlight, using blinds can help keep your room cooler. If you want to let some sun in, you can slightly tilt the blinds upward to let light in while letting the warm air escape.
Tip: Know which windows to close during certain times of the day. Because the sun shines from the south, south-facing windows tend to receive the most light and usually are the hottest. North-facing windows, on the other hand, get the least light and are the coolest. Though east-facing windows receive morning light, it is usually cool. In the afternoon, west-facing windows receive the most light and can become very hot.
Keep interior doors open
Moving air is cooler than still air. To keep the air circulating in your home, leave your interior doors open. This simple step can significantly regulate the room temperature, especially if you don’t have an open-concept living space. Keeping your interior doors open allows air to move freely and eliminates hot spots indoors.
Open windows at night
Though the summer heat is unbearable during the day, the weather can be breezy in the late afternoon. Once the sun goes down, you can open your windows to let the cool breeze in. The most important time to open the windows in summer is at night, when the air is coolest. Doing so will promote cross-ventilation in your home, helping you and your family sleep better. With cool air circulating in your home all night, you’ll have a fresh abode when the morning comes.
You can also keep your windows and balcony doors open early in the morning to let the cool breeze flow into your home while the morning light is not yet very hot.
Tip: To prevent mosquitoes and other bugs from getting into your home, install nets over your door frames and windows.
Turn off unused appliances and lights
Unused appliances that are on will generate unwanted heat in your home. If you’re not using an appliance, like your computer, TV, or kitchen gadget, consider turning it off instead of leaving it on standby. Your lightbulbs can also generate unwanted heat in your house, so make sure to turn them off during the day.
Tip: The type of lightbulb you use can also affect its heat output. To keep your house cool, especially during summer, invest in energy-efficient lightbulbs, which emit less heat.
Plant foliage and invest in houseplants
Plants can act as natural air conditioners by releasing moisture into the atmosphere and purifying the air. To ward off the heat naturally, sprinkle in some houseplants inside your home. They not only make the rooms look refreshing but also improve your mood.
Planting shade trees and green foliage around your house can also help block heat from entering through your windows and roof. Although they may take seasons to grow, they will be a great investment for your home year-round.
Tip: Peace lilies and rubber plants are among the most heat-efficient plants, as they work best in humid conditions and have strong cooling power.
Clean and declutter your home
Lastly, keep your house clean and clutter-free. A messy, cluttered space can restrict airflow, making the room feel hotter and more humid. With respect to air quality, clutter can also pollute indoor air. When you declutter your home, there will be more space for heat to dissipate and for air to move freely, making a room cool faster. Aside from decluttering, make sure to clean every nook, properly store unwanted items and toxic products, and diligently dispose of your garbage.
Bottom Line
You don’t need to spend so much money on air conditioners to keep your house cool when the weather gets too hot. With proper planning and good strategy, you can block off unwanted heat and humidity to make your home more refreshing.
To recap, here are our 6 tips to keep your house cool without running up your electric bills:
- Block the sun out
- Keep interior doors open
- Open windows at night
- Turn off unused appliances and lights
- Plant foliage and invest in house plants
- Clean and declutter your home
