Why an Energy Audit?Why an Energy Audit?

• Identify where energy is going

• Identify savings opportunities

• Part of a comprehensive environmental program

Energy conservationEnergy conservation

Definition: Energy conservation is the practice of decreasing the quantity of energy used. It may be achieved through efficient energy use, in which case energy use is decreased while achieving a similar outcome, or by reduced consumption of energy services.

• Provided a complete break-up and summaries of the total annual energy consumption and cost.

• Helped identify avenues for energy and cost savings.

• Included separate sections for the major areas of energy consumption at our homes.

SuggestionsSuggestions

1. Turn down the temperature of your water heater to the warm setting (48,8 C%).

2. Check if your water heater has an insulating blanket.

3. Start using energy-saving settings on refrigerators, dishwashers, washing machines, and clothes dryers.

4. Survey your incandescent lights for opportunities to replace them with compact fluorescents.

5. Turn down the thermostat, or up in summer.6. Clean or replace furnace, air-conditioner, and

heat-pump filters.

• Improving a homes air tightness (that is, to cut air leakage) can reduce consumption by 15-40% … proper insulation is a must!

• Programmable thermostat is a must• Microwave oven’s use up to 75% less• Laptop computers use 90% less• Switch off the gadgets you don’t use!

Change the light bulbs!Change the light bulbs!• Because fewer watts used thus

less long term cost.• It is easy to swap „normal light

bulbs”, incandescent bulbs to CF bulbs (Compact fluorescent bulbs)

as they are very interchangeable.• Typical reduction of wattage use

is a 60 watt incandescent being replaced with an 11 watt compact fluorescent bulb.

Little harder to doLittle harder to do

1.Pay attention to insulation. Insulation saves in the winter and summer.

2.Insulate hot water pipes and ducts wherever they run through unheated areas. Install heat traps.

3.Seal up the largest air leaks in your house. It’s usually the cut troughs.

4.Install a clock thermostat to set your thermostat back automatically at night.
