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/OBC/BCBC. 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 CAN/CSA F326-M1991 (R2014).
