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.
Who would benefit from this course?
HVAC Designers, HVAC Installers, Builders, Architectural Designers, Energy Advisors, Building Inspectors, Plans Examiners, Wholesaler Counter Staff
Residential Ventilation using CSA F326
Pre-requisite for HRV/ERV Installation & Balancing Fundamentals
March 21-23, 2022
8:30am – 4:30pm
Cost of course before discount – $1,110 + HST
What you will learn
Participants will use extensive worksheets in conjunction with detailed procedures to select equipment, size ducts and specify installation and control details necessary to design ventilation systems that satisfy Building Code requirements throughout Canada based on the National CSA F326 Standard. CSA F326 allows for much greater flexibility and has no scope restrictions compared to local building codes.
Learning Objectives
Calculate the required ventilation and exhaust requirements for residential ventilation systems
Assess the risk from depressurization and size make-up air systems to suit
Describe the distribution requirements
Select ventilation equipment to meet the requirements of CSA F326
Size ducting according to good engineering practice without the limitations of Building Code-based tables
Describe the controls required under CSA F326
Calculate delivered and mixed air temperatures to ensure occupant comfort
Who would benefit from this course?
HVAC Designers, HVAC Installers, Builders, Architectural Designers, Energy Advisors, Building Inspectors, Plans Examiners
Course Format
Prior to attending this course, attendees are required to register for and successfully complete an online module, “Online Basic Principles of Residential Ventilation”
Major Takeaways
Certification as an F326 designer, which is recognized by many jurisdictions
Ability to do designs for circumstances that are outside the scope of the building codes such as houses with more than 5 bedrooms
Since CSA F326 is a performance-based standard the participant will get a much better understanding of the theory of ventilation and how it impacts the rest of the house and its occupants

Residential Ventilation using Section 9.32 of the Building Code
Formerly the Residential Mechanical Ventilation Installers Course
Pre-requisite for HRV/ERV Installation & Balancing Fundamentals
March 14-15, 2022
8:30am – 4:30pm
Cost of course before discount – $865 + HST
What you will learn
Participants will use simple worksheets in conjunction with detailed design procedures to quickly select equipment, size ducts and specify installation and control details necessary to design ventilation systems. All content complies with Section 9.32 of the NBC. Participants will also clearly understand when the circumstances fall outside the scope of 9.32, which will require the use of a more comprehensive standard such as CSA F326.
Learning Objectives
Describe the scope and limitations of designing a ventilation system under 9.32 of the NBC
List which rooms require fresh air and exhaust inlets
Determine the required ventilation and exhaust capacity
Describe the distribution requirements
Identify when make-up air systems are required
Select ventilation equipment to meet the requirements of the NBC
Size ducting according to the NBC and understand when ducts have to be sized using standards outside of the NBC
Describe the controls required under the NBC

HRV/ERV Installation & Balancing Fundamentals
March 18, 2022
8:30am – 4:30pm
Cost of course before discount – $615 + HST
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
Demonstrate the basic methods for balancing an HRV/ERV
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 11, 2022 – 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
Who would benefit from this course?
HVAC Designers, HVAC Installers, Builders, Architectural Designers, Energy Advisors, Building Inspectors, Plans Examiners
Residential Heat Loss & Heat Gain Calculations
March 28-31, 2022
8:30am – 4:30pm
Cost of course before discount – $1,240 + HST
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.
