En e rGu id e Ra tin g S ys te m (ERS ) V.15 S u p p le m e n ta ry S tu d y Gu id eEnergy Advisor ExamIn tro d u c tio nEnergy advisors use the EnerGuide Rating System (ERS) to assess the energy performance andsavings potential of homes at the design, construction and renovation stages. As part of their duties,energy advisors are required to provide helpful advice to homeowners and builders who want to improvehome energy efficiency. Qualified energy advisors must have the necessary knowledge and experiencein the following areas:› The EnerGuide Rating System;› Residential construction practices for low-rise housing, including multi-unit residential buildings(MURBs);› Energy efficiency renovation practices;› Building science;› Basic mathematics, geometry and computer skills;› Data-collection requirements;› Energy simulation modelling using HOT2000;› Good client relations.To register as an energy advisor under ERS V.15, candidates must meet the following criteria: 11Pass the Foundation Level Exam;2Pass the EnerGuide Rating System V.15 – Energy Advisor Exam;3Be affiliated with at least one licensed service organization;4Be registered with Natural Resources Canada by:- Passing the Foundation Level Exam and the Energy Advisor Exam;- Completing the probationary files to the satisfaction of the service organization’s qualityassurance specialist;- Providing proof of a Criminal Record Check to the service organization manager.To register to deliver EnerGuide Rating System services for MURBs, the energy advisor must:1Meet all of the energy advisor requirements listed above;2Pass the Multi-Unit Residential Building Exam;3Complete the probationary files for multi-unit residential buildings to the satisfaction of the serviceorganization’s quality assurance specialist.1Natural Resources Canada. (2017). “Registration Process for an Energy Advisor: Administrative Procedures” (Version 15.4,pp. 18-20). Canada.Ref. No. 83393

However, if deemed necessary by the serviceorganization, the candidate energy advisor may be required to complete additional files.NRCan has developed a complete competency profile (please follow this link 2) consisting of a numberof learning objectives to guide candidates in preparation for the exam. The contents herein are intendedas a supplementary study guide to help candidates assess whether they are ready to pass theEnerGuide Rating System V.15 – Energy Advisor Exam (required for energy advisors and qualityassurance specialists); however, it should not be used as a stand-alone resource to prepare for theexam. Candidates should use this supplementary guide once they believe they are sufficiently preparedto pass the exam. In addition to using this guide, candidates are encouraged to read the latest versionof the references listed herein and consult the NRCan EnerGuide Rating System V.15 – Energy AdvisorExam Competency Profile available on its website 3.This study guide focuses on the Energy Advisor Exam process and directs candidates to the appropriatedocuments needed to prepare for the exam.

The three-hour exam consistsof 150 questions. There are four categories and 27 competencies or subcategories, with a total of 220learning objectives. The four categories are as follows:1The EnerGuide Rating System;2 HOT2000 Modelling Version 11;3 Administration and Delivery of the EnerGuide Rating System Version 15;4 Quality Assurance of the EnerGuide Rating System Version 15 – General.1.1Typical PitfallsOne of the most common mistakes made by candidates when preparing for the EnerGuide RatingSystem V.15 – Energy Advisor Exam, especially those who have already delivered an ERS energyrating under previous versions, is assuming that they have already gained all the fundamentalknowledge needed to successfully pass the new exam. Energy advisors who deliver the 0-100 ERS arewarned that there are significant changes between V.10 and V.15 (see list below). As such, allcandidates are encouraged to carefully prepare for the exam. Lack of preparation is the main cause offailure.Candidates need to master the knowledge required to provide all of the following services:› Basic Service;› Renovation Upgrade Service;› Construction Blower Door Service;› Construction Upgrade Service for New Homes.What follows is a list of the major changes to the ERS standard compared to the former version:› A revised scale that uses actual energy units and provides ratings of homes in gigajoules per year;› An expanded rating scope to account for space cooling;› The EnerGuide Rating now indicates on-site renewable energy contributions;› Updated standard operating conditions;› Provisions for adjusting electrical base loads and hot water loads for zero-rated homes;› Minimized built-in policy-based adjustments to the EnerGuide rating, such as house size or energysource;› Several service delivery types are defined.Ref.
