Consider installing a programmable thermostat.
With this technology, you can set your air conditioner to be turned off at night when it is coolest and you are least active.
Opening windows in the summer costs nothing, but it can save a lot of energy and money.
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.
Ceiling fans use less electricity than air conditioners or furnaces.
For example, a ceiling fan costs about five cents an hour to operate, which is much less than an air conditioner.
Did you know that you use three to five percent more energy for each degree that your air conditioner is set below 24 degrees Celsius or 75 degrees Fahrenheit?
So, set your thermostat to 25 degrees Celsius or 77 degrees Fahrenheit to provide the most comfort at the least cost.
Those living in rural areas can save on energy costs by planting trees and shrubs as windbreaks.
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.
Use awnings and overhangs to keep the sun out of south-facing windows in the summers, then take down the awnings to let the sun shine in during the winter.
You could even plan the overhangs so that they'll shade windows from the high summer sun, but let in the lower winter sun.
Consider upgrading the windows in your home.
Select high efficiency windows with low-e coatings, argon gas fill and insulated spacers.
Have you ever wondered what would happen to your electricity bills, if you allowed your staff to wear more casual clothes during the summer months?
Wearing comfortable, lightweight clothing during the hot weather, rather than business suits, could help reduce your air conditioning bills.
Did you know that a reflective roof could reduce the roof surface temperature by up to 60 degrees Fahrenheit, depending on your climate?
A reflective roof prevents the sun's heat from transferring into the home or building.
