The 1–100 EnerGuide scale
1 = Address
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.
