Puzzling out how to keep your house as cool as possible during these hot summer months? Trying to remember the conventional wisdom but not quite sure how it goes? Find out the answers to these questions and more, right here:
1. Reduce the cooling load by employing cost-effective conservation measures. Provide effective shade for east and west windows. When possible, delay heat-generating activities such as dishwashing until evening on hot days.
2. Over most of the cooling season, keep the house closed tight during the day. Don’t let in unwanted heat and humidity. Ventilate at night either naturally or with fans.
3. Use ceiling fans to increase comfort levels at higher thermostat settings. The standard human comfort range for light clothing in the summer is between 72 F and 78 F. To extend the comfort range to 82 F, you need a breeze of about 2.5 ft/sec or 1.7 mph. A sow-turning ceiling-mounted paddle fan can easily provide this air flow.
4. In hot climates, plant shade trees around the house. Don’t plant trees on the South if you want to benefit from passive solar heating in the winter.
5. Try not to use a dehumidifier at the same time your air conditioner is operating. The dehumidifier will increase the cooling load and force the air conditioner to work harder.
