Hot weather is more than just an inconvenience; it can be dangerous.
Every year, hundreds of people in the U.S. die because of extreme heat, and thousands more need medical help.
With temperatures on the rise, it’s crucial to know how to keep your home cool and safe.
Keep the Sunlight Out
Firstly, block out the sun. Christian Kaltreider, an expert on energy-efficient buildings, says the sun’s rays coming through windows heat up your home quickly.
So, how do you stop it? Use window coverings like drapes, films, or blinds.
Theresa Gilbride, another researcher, points out that insulated cellular shades can cut your air conditioning use by up to 25% compared to having no window coverings at all.
If you can, put up exterior window coverings like awnings or solar screens. These can reduce your need for air conditioning even more—by over 20% compared to no window coverings.
Create a Cool Room
Knowing a heat wave is coming? Set up one room in your home as a ‘cool room.’ Make sure it has air conditioning, fans, and good window coverings.
Also, seal the door well to keep the cool air in. It’s also a good idea to have an air purifier, as hot days often come with bad air quality.
If it’s hotter outside than inside, keep doors and windows shut. If it cools down at night, use fans at windows to bring in cooler air. You can put one fan blowing out at one window and another fan blowing in at another window to circulate the air better.
No Power? No Problem
If there’s a power outage or you don’t have air conditioning, window coverings become even more crucial.
You can even use cardboard or hanging clothes to block out the heat. If the cardboard is lighter on one side, make sure that side faces out. Cold showers and avoiding cooking can also keep your home cooler.
Long-Term Solutions
For those who own their homes and can afford some upgrades, consider landscaping.
Planting trees near windows can provide shade and even create a cooler area around your house. Choose deciduous trees that lose their leaves in winter so you can still get winter sunlight.
If you’re doing renovations, consider heat-resistant options. Look for products with a Cool Roof Rating Council rating when choosing roofing materials or paints. These materials reflect the sun’s heat better. Adding insulation to your attic or walls can also help keep your home cool in summer and warm in winter.
Got leaky air conditioning ducts? Theresa Gilbride recommends having a professional check and seal them. Leaky ducts can be a significant source of lost cooling and higher energy bills.
If you’re thinking of adding an air conditioner, consider ductless heat pumps. They don’t need big renovations, and they can cool your whole house or just one room.
By taking these steps, you’re not just making your home more comfortable; you’re also making it safer for everyone, especially during extreme heat waves. Stay cool!
