What is an energy advisor?
Energy advisors are:
- Third-party consultants registered by service organizations licensed by Natural Resources Canada
- Deliver Natural Resource Canada’s EnerGuide Rating System, ENERGY STAR® for New Homes and R-2000 programs
- Can provide both energy modelling and airtightness testing, the two services needed to demonstrate compliance under the BC Energy Step Code for Part 9 residential buildings
- Only work on Part 9 residential buildings
Energy modellers perform similar work, but may not be affiliated with a service organization and the EnerGuide Rating System; instead, they may use other energy simulation software that meets the BC Energy Step Code’s requirements.
All energy advisors are energy modellers, but not all energy modellers are energy advisors.
For Part 3 buildings, modelling and airtightness testing is done by building envelope consultants and building scientists.
How do I find an energy advisor or energy modeller for my project?

Energy models and why they’re needed
The BC Energy Step Code requires Part 9 builders to work with an energy advisor or energy modeller to review plans, model energy consumption, conduct air tightness testing and verify the plans and as-built home will meet the energy performance requirement of a given step of the BC Energy Step Code.
An energy model calculates how much energy a proposed building is expected to use. Modelled energy consumption in a building can relate to space heating, ventilation, lighting, appliance and plug loads. The energy advisor (or other energy modeller) understands the modelling software, construction details and BC Building Code requirements. The energy model accounts for the size and geometry of the building, the climate at the building’s location, the effective insulation values of assemblies such as walls, ceilings, windows and doors, and the mechanical systems that keep the house comfortable and provide hot water.
Energy advisors can provide advice to home builders who want to improve energy efficiency in the homes they build so they can achieve any of the Part 9 steps. After construction, the energy advisor will visit the home for a site verification visit, which includes a blower door test to measure the building’s airtightness.
Where energy advisors work
Energy advisors don’t have to be in the same community as their projects. They only have to be on-site when doing airtightness testing, not modelling. Typically, energy advisors are able to travel long distances, especially when they can aggregate projects in an area.
In addition, under EnerGuide policy, more than one licensed energy advisor may be involved in the evaluation and modelling process of a single file. When this happens, one energy advisor remains accountable for all aspects of the work: the energy advisor identified on the HOT2000 file, the modelling software used by the EnerGuide Rating System.
Certification of energy advisors
Energy advisors must have a strong understanding of building science principles, write and pass two exams set by Natural Resources Canada (the Foundation Level exam, and the Energy Advisor exam) and work within a strict code of ethics. They must also be registered through a licensed service organization.
The role of service organizations
A service organization is an independent organization licensed by Natural Resources Canada to use the nationally recognized EnerGuide Rating System, a standardized home energy performance rating tool.
Service organizations work with builders and homeowners across Canada in assessing the energy performance and potential energy savings for homes during the design, construction and renovation stage.
Service organizations must adhere to ethics and standards set by Natural Resources Canada, and pass additional exams pertaining to the work they do.
