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.
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.
