With warm weather upon us, we are all looking for ways to stay cool. Did you know ventilation is the least expensive and most energy efficient way to cool your home? It is true.
“Often we resort to man-made measures, such as cranking the air conditioner, that are not as cost-effective as simply opening windows,” says Kimberly Huffman, principal marketing analyst, DTE Energy Energy Optimization. Follow the tips below to help you stay comfortable, while still saving on your next energy bill.
Your Windows Can Bring in Cool Air
For those that keep their air conditioning running around the clock, you may be able to save some energy with the help of Mother Nature. Turn off you’re A/C unit and open windows at night to create a free, fresh, and cool air flow through your house. When you wake in the morning, shut the windows and blinds to capture the cool air and block out the warming rays of the summer sun.
Fans Are a Breeze to Use
Portable fans: At night, place fans in open windows to move in cool air. In the day, put fans where you feel their cooling breezes (moving air evaporates perspiration and lowers your body temperature).
Ceiling fans: If you raise your thermostat by only two degrees and use your ceiling fan, you can lower cooling costs by up to 14 percent.e sure to turn off fans when you’re not in the room, because fans cool people by creating a wind chill effect, they don’t lower the room temperature.
Whole house fans: A whole-house fan exhausts hot inside air back outside through roof vents and depressurizes the air in your home. Make sure your windows are open when you run a whole-house fan.
Ventilation fans: When you shower or take a bath, use the bathroom fan to remove the heat and humidity from your home. Your laundry room might also benefit from spot ventilation. Make sure bathroom and kitchen fans are vented to the outside (not just to the attic). ENERGY STAR certified ventilation fans use 50% less energy than standard models and provide comfort with less noise.
Install Window Coverings to Avoid Added Heat
You can choose window treatments or coverings not only for decoration but also for saving energy. Some carefully selected window treatments can reduce heat loss in the winter and heat gain in the summer. Window treatments, however, aren’t effective at reducing air leakage or infiltration. You need to caulk and weather-strip around windows to reduce air leakage.
