Multifamily Ventilation: 130 units in two Passive House buildings in Vancouver BC

This session contrasts two different approaches to ventilating two 50+ unit Passive House buildings currently in construction in Vancouver BC. The presentation considers the challenges and benefits of using individual HRV's (heat recovery ventilators) in each unit versus a semi-distributed approach of mid-sized HRV's over risers.


Topics covered will include:  ventilation requirements and goals, coordinating building configuration with ducting, unit flows/distribution/noise, elevator shafts and hallways, balancing and commissioning.



Learning Objectives:

At the end of the session, attendees will be able to actively:

  • Identify two different approaches to ventilation configuration.

  • List the design concepts of balanced ventilation with heat recovery using risers.

  • Explain balanced ventilation design concepts within living units, hallways and elevators.

  • Describe commissioning the balanced ventilation system of a large low rise building usingrisers that serve multiple floors.
