Some introductory comments
I have switched to another system of providing you with this newsletter but the purpose remains the same. In the newsletters I hope to give tips that may be of help to you in maintaining your home, in saving energy, in making your home a safer place and other home owner related topics.
If you have any suggestions or requests for future topics, please forward them to me. My email address is in the left column.
Saving Energy in the Home
This month I will give some ideas where you may be able to save on the energy consumption. This is a "to be continued" topic.
1. Find better ways to heat and cool your house.
As much as half of the energy used in homes goes toward heating and cooling. The following are a few ways that energy bills can be reduced through adjustments to the heating and cooling systems:
- Install a ceiling fan. Ceiling fans can be used in place of air conditioners, which require a large amount of energy.
- Periodically replace air filters in air conditioners and heaters.
Changing the furnace or air conditioner filter once every two months is not excessive. Once every month is better.
- Set thermostats to an appropriate temperature. Specifically, they should be turned down at night and when no one is home. In most homes, about 2% of the heating bill will be saved for each degree that the thermostat is lowered for at least eight hours each day. Turning down the thermostat from 75° F to 70°F, for example, saves about 10% on heating costs.
- Install a programmable thermostat. A programmable thermostat saves money by allowing heating and cooling appliances to be automatically turned down during times that no one is home and at night. Programmable thermostats contain no mercury and, in some climate zones, can save up to $150 per year in energy costs.
- At night, curtains drawn over windows will better insulate the room.
2. Install a tankless water heater.
Demand water heaters (tankless or instantaneous) provide hot water only as it is needed.
Demand water heaters heat water directly without the use of a storage tank. Therefore, they avoid the standby heat losses required by traditional storage water heaters. When a hot water tap is turned on, cold water travels through a pipe into the unit. Either a gas burner or an electric element heats the water. As a result, demand water heaters deliver a constant supply of hot water. This is a logical choice when building a new home or when your existing water heater needs to be replace.
3. Replace incandescent lights.  
The average household dedicates 11% of its energy budget to lighting. Traditional incandescent lights convert approximately only 10% of the energy they consume into light, while the rest becomes heat. The use of new lighting technologies, such as light-emitting diodes (LEDs) and compact fluorescent lamps (CFL), can reduce energy use required by lighting by 50% to 75%. Hopefully the CFLs and LEDs will go down in price, making them more attractive to purchase. LEDs for Christmas lights are becoming very popular and affordable but LEDs for home lighting are still quite expensive.
Advances in lighting controls offer further energy savings by reducing the amount of time lights are on but not being used. Here are some facts about CFLs and LEDs:
- CFLs use 75% less energy and last about 10 times longer than traditional incandescent bulbs.
- LEDs last even longer than CFLs and consume less energy.
- LEDs have no moving parts and, unlike CFLs, they contain no mercury.
4. Seal and insulate your home.
Sealing and insulating your home is one of the most cost-effective ways to make a home more comfortable and energy efficient -– and you can do it yourself. A tightly sealed home can improve comfort and indoor air quality while reducing utility bills. An energy auditor can be hired to assess envelope leakage and recommend fixes that will dramatically increase comfort and energy savings.
The following are some common places where leakage may occur:
- electrical outlets and switches;
- mail slots;
- around pipes and wires;
- wall- or window-mounted air conditioners;
- attic hatches;
- fireplace dampers;
- weatherstripping around doors;
- baseboards;
- window frames.
Because hot air rises, air leaks are most likely to occur in the attic. Homeowners can perform a variety of repairs and maintenance to their attics that save them money on cooling and heating, such as:
- Plug the large holes. Locations in the attic where leakage is most likely to be the greatest are where walls meet the attic floor, behind and under attic knee walls, and in dropped-ceiling areas.
- Seal the small holes. You can easily do this by looking for areas where the insulation is darkened. Darkened insulation is a result of dusty interior air being filtered by insulation before leaking through small holes in the building envelope. In cold weather, you may see frosty areas in the insulation caused by warm, moist air condensing and then freezing as it hits the cold attic air. In warmer weather, you’ll find water staining in these same areas. Use expanding foam or caulk to seal the openings around plumbing vent pipes and electrical wires. Cover the areas with insulation after the caulk is dry.
- Seal up the attic access panel with weatherstripping. You can cut a piece of fiberglass or rigid foam board insulation the same size as the attic hatch and glue it to the back of the attic access panel. If you have pull-down attic stairs or an attic door, these should be sealed in a similar manner.
