EnerGuide Home Evaluation
What is an energy advisor?
An energy advisor is an individual who conducts EnerGuide home evaluations on behalf of an NRCan (Natural Resources Canada) licensed service organization. Energy advisors provide unbiased, third party expert advice on energy use and savings to homeowners and builders.
What is an EnerGuide home evaluation?
An EnerGuide home evaluation is a service that provides homeowners information on increasing energy efficiency and comfort in their home. Understanding your home’s energy performance can help you make informed decisions when operating or renovating your home. An energy evaluation provides information that can help you better understand your home energy allocations, allowing you to make the best energy efficient choices towards utility costs.
When undertaking renovations or upgrades of your home, having a Home Energy Advisor perform a comprehensive assessment is a smart choice. A full assessment will determine where you can benefit most from your upgrades and increase energy efficiency. The advisor enables you to make informed decisions. This can be an invaluable tool for you and your renovation contractor when planning your home improvement project. A well-educated homeowner saves money and assures greater comfort for the family home.
An assessment typically takes 2 to 2 ½ hours. Upon completion of the evaluation, the following will be provided:
- An EnerGuide rating and label that displays the rated energy consumption in GJ/year per square meter.
- A Homeowner Information Sheet that includes detailed information about your home and its energy use.
- A Renovation Upgrade Report that provides a detailed customized roadmap with recommendations for improving your home’s energy performance. This is ideal for existing homeowners who are looking to renovate their home to make it more energy efficient.
– Optional Follow-up Home Rating
After completing your upgrade recommendations, having a second energy evaluation is helpful as it provides you with a revised and improved EnerGuide rating, Home information sheet and new label. This revised information shows how your improvements increase your home’s energy performance.
This will take approximately one hour to complete and includes a blower door test.
What is an EnerGuide Rating?
An EnerGuide rating and label (new EnerGuide label, version 15) displays the energy performance of your home by estimating the net amount of energy a home utilizes in a year. The newly integrated EnerGuide Rating System calculates the energy consumption of a home in gigajoules per year. This system ensures the rating focuses on the house rather than the occupants’ activities. By using standard operating conditions. This new, energy use based rating has come into effect in Alberta as of July 1, 2016.For more information, visit http://www.nrcan.gc.ca/energy/efficiency/housing/home-improvements/18684
What to expect during an EnerGuide Home Evaluation.
During the on-site evaluation, we will collect the following data from your home:
- We will perform a comprehensive assessment of the building envelope: windows, doors, ceilings, walls, foundation. A visual inspection and measurement is done to determine surface area, insulation levels, dimensions/volume and the orientation (to accommodate for solar gain) of your home.
- We perform a comprehensive assessment of mechanical systems: heating system, air conditioning, ventilation system and water heater.
- Blower door test: (A Blower Door Test is performed to determine the air tightness of your home and identify air leaks) With the
- Blower Door running, we will walk with you throughout your home to identify common areas of air infiltration. A Blower Door test will determine:
Measurement of air changes per hour at 50 Pa
- Location of major air leakage areas/ ELA (estimated leakage area) of the home. The ELA is expressed in square inches
- Depressurization test when required (combustion spillage)
- Energy modelling of all components to determine the energy efficiency of your home.
- By comparing your home to a home built to a 2010 NBC National Building Code (as a baseline)
- Recommended home upgrades and potential energy savings
- ERS certified label for your home
- Intensity energy rating of your home
The energy assessment will provide you with calculated potential energy savings on any recommended upgrades. A custom certified ERS report and label for your home.
Am I obliged to undertake the recommended upgrades?
No. This is simply a consulting service that provides homeowners information on increasing energy efficiency and comfort in their home. There is no obligation to undertake any of the recommended upgrades.
When is a follow-up evaluation recommended?
- When applying for government grants (In Alberta CMHC mortgage insurance rebate is the only option presently) https://www.cmhc-schl.gc.ca/en/co/moloin/moloin_008.cfm
- If you have made major improvements to the energy efficiency of your home after the initial energy evaluation, new rating and label is recommended. Especially if you are selling your home as this a great feature to have and may increase your home value.
