The 1–100 EnerGuide scale
EnerGuide Rating: 0-100 Scale
Text version
1 = Address
2= Rating
3= least efficient to most efficient
4 = File Number
5 = Service Organization
6 = Name of Energy Advisor
7 = Date of Energy Report
This rating is a snapshot of your home’s efficiency at the time of the evaluation.
- A 0 rating represents a house with major air leakage, no insulation and high fuel consumption.
- A 100 rating represents an airtight, well-insulated house where energy purchased is equal to energy generated through renewable sources: a “net-zero” home.
- The higher the number, the more efficient the house.
- An energy-efficient, upgraded older home typically rates between 66 and 74; an energy-efficient new home rates between 81 and 85.
| House Characteristics | Typical ERS Rating |
|---|---|
| Existing house not upgraded | 0 to 50 |
| Upgraded existing house | 51 to 65 |
| Energy-efficient upgraded existing house | 66 to 74 |
| New house built to building code standards without energy requirements | 70 to 76 |
| New house built to building code standards containing energy requirements | 77 to 80 |
| Energy-efficient new house | 81 to 85 |
| High-performance, energy-efficient new house | 86 to 99 |
| Net zero house (energy purchased and energy generated, through renewable sources, is equal) | 100 |
Reading your EnerGuide evaluation results
Your EnerGuide label and energy efficiency evaluation report show your home rating both as a number and a point on the 1–100 scale. The label shows
- your home address and file number
- the date of your evaluation
- contact information for your energy advisor
- the version code of the energy efficiency software
- a checklist of recommended energy efficiency retrofits
If you make the recommended improvements and get a follow-up evaluation, you’ll receive a revised EnerGuide rating, label and report.
