With this technology, you can set your air conditioner to be turned off at night when it is coolest and you are least active.
Consider keeping your windows open in the evening and overnight to allow cooler air into your home, and don't forget to turn off your air conditioner. Close the windows during the day to keep the cool air in and the warm air out.
For example, a ceiling fan costs about five cents an hour to operate, which is much less than an air conditioner.
So, set your thermostat to 25 degrees Celsius or 77 degrees Fahrenheit to provide the most comfort at the least cost.
Windbreaks around your home can reduce wind by up to 50 percent and heating costs by 20 to 40 percent. Even in calm areas, windbreaks can reduce energy costs by 10 percent. Place your windbreak at right angles to the prevailing winter winds. Even a few well-placed trees can make a difference.
You could even plan the overhangs so that they'll shade windows from the high summer sun, but let in the lower winter sun.
Select high efficiency windows with low-e coatings, argon gas fill and insulated spacers.
Wearing comfortable, lightweight clothing during the hot weather, rather than business suits, could help reduce your air conditioning bills.
A reflective roof prevents the sun's heat from transferring into the home or building.
