Online Basic Principles of Residential Ventilation
Pre-requisite for Residential Ventilation using Section 9.32 of the Building Code & the Depressurization Testing of Residential Systems
Self-paced Online Module – Can be completed anytime
Allow 2-3 Hours for Completion
($90 Value)
What you will learn
Through this online course, participants are introduced to the basic principles of residential ventilation. We start by defining the concepts known as “House as a System”; the flow of air, heat and water and how these impact natural ventilation (aka air leakage). Then we move on to describing the theory of mechanical airflow including air pressure, duct resistance and fan ratings. A review of the impact on combustion appliances, humidity levels and indoor air quality is also provided.
There are lots of visuals and periodic quizzes to reinforce the learning objectives!
Major Takeaways
Understand the basic building science principals that are the foundation for ventilation design and commissioning.

What you will learn
Participants will receive the skills and knowledge to balance the airflows of Heat and Energy Recovery Ventilators (HRV/ERVs). They will also have an overview of the installation and measurement requirements. An HRAI checklist for installation and servicing of HRVs and ventilation systems will be made available, for use when on the job.
After an instructor-led demonstration, participants will be divided into two groups to complete a hands-on assessment of balancing and a brief exam on installation requirements and the theory and application of air flow measurement. Participants are encouraged to bring their own measuring equipment and use it in a comfortable learning environment.
Learning Objectives
Describe the basic requirements for locating equipment including grills
Explain how to install the condensate line for an HRV/ERV
Use commonly available equipment for measure air velocity and/or flow

Understand when it may be necessary to consult with the designer on issues discovered on site
List various ways to improve the airflow in an existing duct system
Describe the ways that airflow can be adjusted
Interpret a ventilation design to determine the airflow required from the HRV/ERV
Deadline to Register:
March 5, 2021 – NOON
Prerequisite
Details vary depending on the local code, so participants are required to attend HRAI’s Residential Ventilation using Section 9.32 of the Building Code OR Residential Ventilation using CSA F326 course before being able to attend the HRV/ERV Installation & Balancing Fundamentals course.
Major Takeaways
Certification as an HRV/ERV Balancer, which is recognized by many jurisdictions
The ability to use a variety of flow measuring devices to measure and balance air flow
A good understanding of installation practices

Residential Heat Loss & Heat Gain Calculations
March 16-19, 2021
9:30am – 5:30pm
$1,400 Value
What you will learn
Based on the CSA Standard F280-12, students get a firsthand introduction of the basic principles of building science and heat loss/gain. Through various in-class exercises, the student will learn how to determine the thermal resistance (R- value) of various building assemblies, such as walls and ceilings. Accurately, calculate room by room heat loss and gain while considering the influences of occupancy, exposure, ventilation, air leakage across the building envelope and more.
Major Takeaway
Get recognized by municipal building officials and plans examiners for having the technical competency needed to perform residential load calculations and size heating and cooling appliances accordingly.
