The American Homeowners Foundation (AHF) is providing this free Home Energy Audit to help homeowners reduce energy consumption costs. The National Energy Assistance Directors Association predicts that home heating oil bills will cost $2,200 in New England this winter, up from an average of $900 per heating season from 2000 through 2005. The costs of home heating oil in other parts of the country as well as other energy sources used for home heating and cooling are expected to rise substantially in 2007 and 2008 as well.
There are many things homeowners can do to reduce home energy costs. Many of them are lifestyle related. While inside your home wear warmer layered clothing in the winter and light and loose fitting garments in the summer and you’ll use less energy for heating and cooling. Try to spend more of your time in warmer parts of your home in the winter and the coolest part of your home in the summer and you’ll also use less energy for heating and cooling. The top floor of the south side of a home is usually the warmest and the lowest level of the north side is usually coolest.
Don’t ignore other ways to save energy outside of the home as well. Today you can buy many of the products you need on the Internet and have them delivered to your home for less than their price at the mall or shopping center, and still save money after adding shipping costs and subtracting the cost of the gasoline you would have used driving to the store. By not driving you’ll be helping to reduce global warming and will probably save time as well. Also employers are becoming more open to letting employees work from home at least occasionally, so it wouldn’t hurt to ask if your boss would let you telecommute. Tax credits for the purchase of hybrid vehicles can also significantly reduce their added cost and the time required to make up the difference through savings on gasoline.
Homeowners can significantly reduce energy costs through several simple and inexpensive do-it-yourself steps that will recover their costs through energy saving very quickly. The costs of more comprehensive energy reduction solutions can be reduced by federal tax credits of up to $500 for expenses to upgrade heating and air conditioning systems, insulation, windows, doors and thermostats, caulk leaks, install pigmented metal roofs and otherwise reduce energy costs (the tax credits will expire on December 31, 2007, but there is a good chance that Congress will extend them). A number of states also offer tax credits for things like solar energy systems and/or rebates or other incentives for things that can reduce energy use. The Environmental Protection Agency has created a free calculator that you can use to customize you own personal energy reduction plan: www.epa.gov/climatechange/wycd/calculator/ind_calculator.html
AHF’s Ten Minute Home Energy Audit will help you identify steps you can take to significantly reduce your home’s energy consumption. This a quick guide and scorecard will help you focus on the most obvious and cost-effective steps you can take to reduce energy consumption and increase comfort levels in your home. The greater the range in points, the more energy that can be saved. The Audit will require you to explore your house using a flashlight, ruler and screwdrivers. We will start in the room containing your furnace if you have one, then work your way through each room to the attic.
Please give yourself the appropriate points for each category listed below, and then add them up when you’re finished. How energy efficient is your home? Here’s the scale:
100+ points Triple A+ Model of Energy Efficiency, well done!!
80 to 100 A, your house is in excellent energy shape
70 to 80 Great shape, some minor improvements encouraged
60 to 70 Passes, yet obvious room for energy improvements
50 to 60 Not good – you have high utility bills and comfort problems
50 & below Your house needs major help! Seek professional advice to reduce energy costs

4. Hot water heater temperature
What is the temperature setting of your hot water heater? Note: If electric please turn off power at the circuit breaker if you need to open access panels to read.
If the temperature is set to 110F or vacation warm, give yourself 5 points.
If the temperature is set to 120F or warm, give yourself 4 points.
If the temperature is set to 130F or warm plus, give yourself 3 points.
