It is open to facility owners, managers, designers, engineers and users.

Integral Group is proud to be represented by Vancouver Project Manager Mary On in her session:

HEAT RECOVERY | Is Heat Recovery Always Worthwhile?

Session I3 | Wednesday, October 17, 2018 | 10:30am –  12:00pm

Many laboratories recover waste heat from fume hood exhaust using runaround coils; however, it requires special maintenance procedure as the filters and coils in the exhaust air stream are contaminated by chemicals and are hazardous. The maintenance staff often needs to consult with the Health and Safety department prior to starting work and will need to wear the appropriate PPE. The dirty filters will also need to be handled and disposed of as hazardous waste. This special maintenance procedure is lengthy and expensive over the lifetime of the building. Given the complicated and costly maintenance required, the design team should carefully weigh the pros and cons of incorporating fume hood exhaust heat recovery, and balance the amount of energy that could potentially be saved with the operating cost. It is possible for a lab to achieve high energy performance without fume hood heat exhaust. This presentation will look at how two university lab buildings achieve low energy use intensity (EUI) without the use of fume hood exhaust heat recovery. The two case studies include the Quantum Matter Institute (QMI) at the University of British Columbia, and the Health and Science Centre and the Vancouver Island University.
