An EnerGuide Rating assigns a value of 1 to 100 to a home depending on energy efficiency. Using the NRCan-endorsed HOT2000 software, a Certified Energy Advisor will work with you to evaluate how energy efficient your existing homes are and begin to make recommendations for improvement.

|Program Requirements:||HOT2000 Modeling. A Certified Energy Advisor (CEA) working with EnerVision will take your house plans and produce a detailed software model describing the energy efficiency of the design. Factors such as window layout, insulation, house volume, furnace efficiency and more are all accounted for in this model.
Blower Door Testing. Once the home is built and all openings are sealed (including windows, doors and attic hatches), you will schedule a visit from your CEA to test the air tightness of the home. All windows and doors are closed, and a device is affixed to a door which is able to measure air leakage in the home.
EnerGuide Label. After the Blower Door Test is completed, your CEA will input the measured air leakage data into your HOT2000 model, and a final EnerGuide rating and label for the home will be produced. This label is endorsed by NRCan and can be delivered to the homeowner and/or affixed ot the breaker box in the home.
Know where you're at. Modeling and blower door testing your existing homes will give you an understanding of where you stand in terms of energy efficiency, which is the first step to building green.
Get reccomendations for improvement. Once a home is modeled, your CEA can adjust parameters in the model and let you know where it will benefit you most to improve your home design and construction.
Value-added for your homeowners. At the end of the day, you can provide proven, government-endorsed quality assurance to your homeowners as to the energy efficiency of their home. This equals lower utility bills and lower greenhouse gas emissions for the home.

|51 to 65||Upgraded old house.|
|66 to 74||Energy-efficient old house, or typical new house. NRCan suggests that EnerGuide 72 is the current (2009) average for new homes built in Canada.|
|75 to 79||Energy-efficient new house.|
|80 to 90||Highly energy-efficient new house.|
|91 to 100||Represents an "advanced house" that uses little or no purchased energy.|
