When deciding if you need an energy audit, a good rule of thumb is 10 cents per square foot. If your highest utility bill divided by the square footage of your home is 10 cents per square foot or more, you have room for improvement. For example, a $200 electric bill divided by a 2,000 square foot house would be 10 cents a square foot. This home would have room for improvement. The higher the cost per square foot, the more room there is for improvement.
