To understand our tips for keeping cool in summer, you'll need to understand how heat, cool air, and your body works. Heat and cooling use three methods of crossing your path: they both share conduction, radiation, and convection. Perspiration is a method of cooling the body.
Conduction happens when the walls, windows, and roof absorb heat. It is then conducted to the nearest person, where it heats the body. Radiation is how you can feel the heat of a stove element from across the room. Convection is when warm air in the home rises. When it wafts across your body, you feel the warmth.
Now, reverse this for cooling. Convection happens when cool air takes your body heat and moves away. Radiation will occur when your body heat radiates toward the cooler objects around you such as furnishings. As heat leaves the body through perspiration, it leaves behind a cool body. With that said, here are tips for controlling cooling costs this summer.
They aren't large, but they emit powerful heat. Using LED bulbs is energy-efficient; they emit almost no heat.
Open the windows at night. The cool air will enter the bottom windows while the warm will exit the top floor windows. It's called the “stack effect.” Close the windows in daylight to conserve the cool air.
3. Window Treatments
Using window treatments wisely cuts cooling costs. Southern and western exposures need drapes with reflective backs. Cellular shades trap heat within the cells so it doesn't enter the house. Awnings and outdoor plantings such as tall trellises cut heat as well.
4. Use Fans
Ceiling fans cool people, not rooms. Turn them off when you're not in a room. Use bathroom fans and stove exhaust fans to take humidity out of the air.
