Correct Sizing Residential Mechanical Systems (Heating/Cooling/Ventilation)

This session is designed for builders, architects, mechanical designers, energy advisors, and construction professionals who want a practical understanding of how residential ventilation and heating systems should be properly sized. We will review the three primary ventilation design methodologies—Building Code 9.32, CSA F326, and ASHRAE—and discuss when each approach should be used and why proper ventilation sizing is critical to building performance, occupant comfort, and indoor air quality.

We will also cover the fundamentals of residential heating system sizing using CSA F280, including heat loss calculations, outdoor design temperatures, and common sizing mistakes that lead to comfort and performance issues. By the end of the session, attendees will have a better understanding of the calculations behind residential mechanical design and the confidence to make more informed decisions on future projects.

Free to attend. Practical. Technical. Valuable. All in just 30 minutes.
