Energy Score (ES)

What is the Energy Score?

The first important thing to know is that this is a “product energy score”. We try to allocate an Energy Score (ES) to each product we carry based on the relevance of the product to the overall energy efficiency of the home/building. The score goes from 0 to 10. The higher the score is, the more energy efficient the product. Our ES is depicted with the graphic and coloring below. There are five different energy scores and colors and one N/A.

Energy Score (ES)

Why do I need it?

The world of energy efficiency is vast. It can be intimidating though it should not be. Our mission is to help educate our clients understand energy efficiency better. The purpose is to make you aware of which products will generate the most energy efficiency return to you as a homeowner. We know that you do not have an infinite amount of money to spend on your home and that that you need some guidance. We believe the ES is one way to appreciate the purchase you are making and its contribution to your home energy savings and carbon footprint.

How is it derived?

We tried to keep our ES as simple as possible, yet wanting it to express the relevance of each product to energy efficiency. Our ES is to a large extent based on yearly homeowners energy consumption data provided by the US Department of Energy and on the similar principles of the RESNET* - HERS index (*see below about RESNET). In addition products that have received certifications or labels from Energy Star, Water Sense, HVI and others get an additional boost to their ES as these labels are only given to products that meet high standards and criteria of energy and water efficiency.

How accurate is it?

While the ES is not perfectly accurate, we believe it gives you directional guidance and advice on the relative merit of each energy efficient product. We will be updating these scores as circumstances change and as more data becomes available. The ES should not be the sole determinant of your purchase

Energy Scores and brackets

All in all there are 5 different Energy Scores and brackets and one N/A score.

Energy Score (ES)
N/A - this score is given to products that are considered accessories to an energy efficient products. For instance a construction tape purchase while a must if you are purchasing a housewrap does not by itself lead to better energy efficiency in the home. Similarly a foam gun is an accessory to a spray foam kit.

0-2 – On a scale of 10 this is the lowest energy efficiency score. Normally it means that the product is not in a high priority section of the house or the product does not contribute to a large percentage of an average home’s energy spending or both. If the product does not have major certifications or labels from the organizations described above it may also not have a strong ES.
Energy Score (ES)

2-4 – On a scale of 10 this score is slightly better than the lowest energy efficiency score. Normally it means that the product is not in a high priority section of the house or the product does not contribute to a large percentage of an average home’s energy spending or both. If the product does not have major certifications or labels from the organizations described above it may also not have a strong ES.
Energy Score (ES)

4-6 – On a scale of 10 this score is an average score, and better than two other lower ES scores. Normally it can mean that the product may be in a high priority section of the house and/or the product contributes to a large percentage of an average home’s energy spending. The product may or may not have major certifications or labels from the organizations described above.
Energy Score (ES)

6-8 – On a scale of 10 this score is above average, and better than three other lower ES scores. To get this score, a product normally has to be in a high priority section of the house and possibly contribute to a large percentage of an average home’s energy spending. The product may or may not have major certifications or labels from the organizations described above.
Energy Score (ES)

8-10 – On a scale of 10 this score is the highest that any product can be. To get this score, a product normally has to be in a high priority section of the house and contribute to a large percentage of an average home’s energy spending. The product most likely has earned major certifications or labels from the organizations described above.
