I wrote the other day about different types of energy audits available. Since I live in an apartment, I went with the free online energy audit offered by my power company. Without the blower door test or thermographic scan performed by a professional auditor, and without anyone from the power company actually visiting my home, the results are generic. But they're a good place to start.
Typical Annual Electrical Usage
All other uses.....5%
My Comments: This table indicates that the best place to focus my efforts in energy efficiency would be in cooling my home.
Your Monthly Electrical Usage
In this section of the report, they created a graph comparing my monthly energy costs and the average temperatures for those months.
My Comments: Since I've only lived here for eight months, it's hard to get a good visualization of my energy usage. But so far, I can tell that I paid the most on energy in August, February, and March.
Medium Potential Savings
- Replace your water heater with a solar system ($2,250-$3,350)
- Raise cooling temperature when not at home (no cost)
- Install tinted window film ($2-4 per sq. ft.)
- Install ceiling fans ($35-$150)
- Get your cooling system serviced ($40-$75)
- Use a clock thermostat to control cooling temperatures ($100-$250)
- Replace old appliances with high-efficiency models ($200-$1,000)
- Add trees or awnings to shade windows during summer ($500-$2,500)
- Shade windows with east or west exposure in the summer (no cost)
- Open shades during the heating season (no cost)
- Clean refrigerator coils ($no cost)
- Set your water heater thermostat to 140 degrees (no cost)
- Wash and rinse laundry in cooler temperature water (no cost)
- Repair leaking water pipes, faucets, and showers (no cost)
- Install electrical outlet gaskets ($.15-$.90 each)
- Change your air conditioner filter monthly ($.50-$8)
- Insulate the hot water pipes from your water heater ($1-$2 L.F.)
- Install energy efficient lighting (variable)
- Fix refrigerator door seals ($55-$85)
- Install an outside combustion air kit and tight fitting glass doors to your fireplace ($100-$300)
Even so, most of these suggestions are things I have no control over, but at the very least, I can do the "no cost" solutions.
If anyone else has gotten an energy audit from their power company, I'd be interested to hear about your results. Similar to mine, or does your power company do a better job of personalizing their report?
