When it is time to buy a household appliance, you can easily view how much it will cost to operate it with the bright yellow EnergyGuide label. Columbia Water & Light is using this same approach for homes. The Efficiency Score is an official certification program that will show you and potential buyers of your home the value of your energy efficiency upgrades. Watch a video about the Efficiency Score.
The Efficiency Score is a FREE service for participants of the Home Performance with Energy Star program. This program is a whole-house approach to energy efficiency. The recommended measures are realistic and cost-effective. To help finance the energy efficiency upgrades, Columbia Water & Light offers up to $1,200 in rebates and low-interest loans.
One of our approved Home Performance with Energy Star contractors will do a complete energy assessment of your home and provide suggested improvements along with an estimated Efficiency Score. Several factors go into scoring your home, including but not limited to:
• levels of insulation
• amount of air leakage
• equipment efficiency
• size of home and materials used
• number of rooms
Sample Efficiency Score Certificate
After upgrades are made, Columbia Water & Light will mail the official certificate. It shows your home’s energy efficiency rating with 100% being the most efficient and your home’s annual energy costs. Your home is compared to itself and the maximum cost-effective efficiency possible.
Columbia Water & Light’s Efficiency Score indicates the percentage of a home’s maximum energy efficiency potential as modeled by the U.S. Department of Energy’s Home Energy Score. The maximum energy efficiency is based on recommendations that provide a 10-year payback or less. Annual energy cost is based on equipment efficiency, size of home and number of bedrooms. Actual costs may vary due to weather, shading, occupant behavior, number of occupants and home maintenance.
Know how your home compares
The Home Energy Score gives you a quick understanding of your home’s energy performance, much like how your car’s miles per gallon (MPG) rating lets you know how efficient your car is. The size of your home matters because larger homes tend to use more energy. If two houses have the same structure and equipment, but one is bigger, the smaller house will generally receive a higher (better) score.

You will be given an initial Home Energy Score after the assessment and then a final Home Energy Score once you complete the upgrades. This U.S. Department of Energy certification program will show you the value of your energy efficiency upgrades. It can also be used for documentation of your efforts to a future buyer of your home.
What does your score mean?
A higher score means a more energy efficient home. Using the Home Energy Scoring Tool, your home will be scored on a scale of 1 to 10. The score with improvements represents the most efficient your home can be with cost-effective measures. Keep in mind: Your home may not be able to score a 10 due to your home’s size or other conditions. A score of 10 indicates that the home uses very little energy and is a smaller home. A score of 1 indicates the home is probably a larger home or needs extensive energy improvements.
