City Green's Certified Energy Advisors are trained to use diagnostic testing and software to assess the energy performance of private homes across B.C. Target areas include windows, doors, insulation as well as heating and ventilation systems.
Using measurements and information about these components of your home, we can calculate your home's total energy efficiency levels or EnerGuide rating - a number between 1 and 100. The higher the number, the higher your home's energy efficiency.
Your current EnerGuide rating will appear in your home energy report, as well as your potential EnerGuide rating, based on the completion of all the recommendations in the report. The final report includes individualized renovation suggestions for increasing your home’s energy efficiency. During your follow up assessment, we will calculate your new, improved EnerGuide rating, based on the retrofits you choose to complete. You will receive an EnerGuide label as well as a grant cheque from Natural Resources Canada.
A comparison of average EnerGuide ratings is shown below:
House Characteristics | Typical Rating | As built to the following standards... |
| Unimproved older house | 0 to 50 | pre 1970s building code |
| Partially improved older house | 51 to 65 | 1970s - 1980s building code |
| Fully improved older house | 66 to 75 | 1990s building code |
| Typical new house | 68 to 82 | Current building code |
| Energy-efficient house | 80 to 90 | R-2000 home |
| Super energy-efficient house | 91 to 100 | Net zero homes |
By increasing our home's energy efficiency, British Columbians can also reduce the amount of greenhouse gas emissions we produce - one important step towards addressing energy-related environmental problems.
