The Energy Efficient Home

Whether you are buying a new house or looking to save money on your current energy bills, it makes sense to assess your home’s energy consumption. Energy efficiency not only helps you save money on your utility bills, it also helps the environment.

A well insulated house stays cooler in the summer as well as keeping its heat in winter. Insulation ratings are measured in “R-values”, which measures how well it resists the transfer of heat. The higher the R-value the better insulated your house will be. R-40 is recommended for attic insulation. Insulated basements, though often overlooked, can improve the comfort of your home – in these areas R-12 or greater is recommended. Also, seal all cracks and other air leaks. If you add up the total size of the hidden leaks in your home, it can be the equivalent of leaving a window open!

Single paned windows aren’t very efficient at stopping heat transfer, which means that you may be paying for heat that is going right through your windows. Double and single paned windows are more efficient, as are coated windows. Can’t afford new windows? Many home improvement and hardware stores offer do-it-your-self window seal kits that allow you to attach a second seal using a hair dryer. Also, make use of your curtains! Keeping them drawn on summer days while you are at work will keep the heat out.

Lighting accounts for five to ten per cent of your total energy use. This is an easy area to reduce your costs. The most obvious (but often overlooked) way to cut costs is to always turn off the light when you leave a room. Make use of the natural lighting available and choose lighter colors for your interiors. Use task lighting instead of general ceiling lights – by focusing your lights on the task at hand you can cut the energy output. Keep your lights clean – cut through dust and cut your costs. Most indoor light bulbs are incandescent, which are particularly inefficient. More than 90 per cent of the energy used by these bulbs is wasted on heat, not light (ever try to change a light bulb that’s been on for a while?). By choosing compact fluorescent bulbs you can cut your lighting energy by up to two thirds. These bulbs also last up to eight times longer than regular light bulbs.

Appliances and home electronics use a lot of energy. A general rule is to keep them unplugged and turned off when not in use. Choose more energy efficient models when replacing older models.

Turn off your computer when you aren’t using it. Not only do older computers use a lot of energy, the screen saver function can draw more energy than when the computer is in use. If you are planning to come back to the computer shortly, turn off the monitor.

Another area to consider is your water consumption. You can save money on your water heating costs by washing your clothes in cold or warm water instead of hot, using low flow showerheads, and only running the dishwasher or washing machine with a full load. Insulate your electric water heater and wrap the exposed hot water pipes to stop the loss of heat.

By taking a few steps to consider your home’s energy consumption you can save money and become a greener family. by making a few small improvements you are well on your way to improving the comfort and resale value of your property.

Energy Saving Tips

Astonishingly, Americans generally spend $1600 or more a year on their utility bills. Not only is much of this wasted energy, but more carbon dioxide is emitted into the air from one home than two average cars. The following tips will help you save energy costs both at home and in the car.

*Set your thermostat comfortably low in the winter and comfortably high in the summer. Install a programmable thermostat that is compatible with your heating and cooling system.

* Use compact fluorescent light bulbs.

* Air dry dishes instead of using your dishwasher’s drying cycle.

* Turn off your computer and monitor when not in use.

* Plug home electronics, such as TVs and DVD players, into power strips; turn the power strips off when the equipment is not in use (TVs and DVDs in standby mode still use several watts of power).

* Lower the thermostat on your hot water heater to 120 degrees Fahrenheit.

* Take short showers instead of baths.

* Wash only full loads of dishes and clothes.

* Drive sensibly. Aggressive driving (speeding, rapid acceleration and braking) wastes gasoline.

* Look for the ENERGY STAR label on home appliances and products. ENERGY STAR products meet strict efficiency guidelines set by the United States Environmental Protection Agency and the United States Department of Energy.

Energy Auditing Tips:

* Check the insulation levels in your attic, exterior and basement walls, ceilings, floors, and crawl spaces.

* Check for holes or cracks around your walls, ceilings, windows, doors, light and plumbing fixtures, switches, and electrical outlets that can leak air into or out of your home.

* Check for open fireplace dampers.

* Make sure your appliances and heating and cooling systems are properly maintained. Check your owner’s manual for the recommended maintenance.

* Study your family’s lighting needs and use patterns, paying special attention to high-use areas such as the living room, kitchen, and outside lighting. Look for ways to use lighting controls – like occupancy sensors, dimmers, or timers – to reduce lighting energy use, and replace standard light bulbs and fixtures with compact or standard fluorescent lamps.

Insulation Tips

* Consider factors such as your climate, building design, and budget when selecting insulation R-values for your home.

* Use higher density insulation, such as rigid foam boards, in cathedral ceilings and on exterior walls.

* Ventilation plays a large role in providing moisture control and reducing summer cooling bills. Attic vents can be installed along the entire ceiling cavity to help ensure proper airflow.

* Recessed light fixtures can be a major source of heat loss, but you need to be careful how close you place insulation next to a fixture unless it is marked IC.
