What is an EnerGuide Rating?
An EnerGuide Rating and Label demonstrate the energy performance of your home. It estimates the net amount of energy a home consumes in a year. Our energy advisors produce a rating by collecting house information during an on-site evaluation and entering the data into Natural Resources Canada’s energy simulation software, HOT2000. The calculation uses standard operating conditions to ensure the rating focuses on the house rather than the occupants’ behaviours.
An EnerGuide evaluation can help you make informed decisions when operating, renovating or purchasing a home. An evaluation is the first step to help you better understand your home’s energy usage so you can make the best energy efficiency choices to save on utility costs and improve the comfort of your home.
Planning to renovate? An evaluation will help you make informed decisions on which upgrades work best for your home, how to prioritize them and which upgrades will save you most on energy costs. There is no obligation to undertake the recommended upgrades, our advisors simply provide a non-biased consulting service that provides you with the best information on how to increase the energy efficiency and comfort of your home.
Purchasing a home? Look for the EnerGuide label on the electrical panel to get a snapshot of the home’s energy performance.
What is included in an EnerGuide evaluation?
During the on-site evaluation, our advisors will collect the following information:
- A complete review of the building envelope (windows, doors, ceilings, walls, foundation)
- Visual inspection and measurement to determine surface area and insulation levels
- A complete review of mechanical systems (heating system, air conditioning system, ventilation system, and domestic hot water)
- Blower door test
- Depressurization test where required (combustion spillage)
- Measurement of air changes per hour at 50 Pa
- Location of major air leakage areas
- Energy modelling of all components to determine the energy efficiency of your home
- Compared to a new home built to 2010 NBC National Building Code
- Individual recommended upgrades with associated potential energy savings
- ERS certified label for your home as it currently stands
- Intensity rating of your home
What will you receive from an EnerGuide evaluation?
Our advisors will provide you with detailed information about your home’s energy performance and will consult with you which retrofit options are best for reducing your energy consumption. You will receive the following after the evaluation:
- An EnerGuide rating label that shows the rated energy consumption of your home in GJ/year per square meter
- A detailed Homeowner Information report that includes information about your home’s current energy use
- A Renovation Upgrade Report that includes a customized road map that will help you make decisions about which renovation options save the most energy and money and which upgrades improve the overall comfort of your home.
If you are planning energy efficiency improvements, a follow-up evaluation may be required if you wish to use the revised and improved EnerGuide rating to demonstrate how the upgrades have increased your home’s energy performance. This may be particularly useful when selling your home. A follow-up evaluation may also be required for available rebates on energy efficient upgrades.
