Time for an Air Change; Advancing Demand-Controlled Displacement Ventilation Webinar

Speaker: Alex Hutton, Tariq Amlani and Greg Allen
This session will summarize current research findings and best practices from the Displacement Ventilation Emergence in Healthcare (DiVE) multi-year research and engagement initiative that seeks to advance the application of DV in Healthcare. The DiVE initiative is intended to advance the application of DV at three distinct levels: expand (more projects similar to what has already been implemented in Canadian Healthcare); extend (to more space types and building types), and lastly evolve (more advanced applications of DV to maximize the full potential benefits including for example DV in conjunction with variable or demand-controlled ventilation). The research is still underway; therefore, some specifics of the findings may evolve between now and the presentation. Examples of anticipated findings are included here. For example, CO2-based ventilation rates correlate with occupancy, cooling demand, and aerosol respiration resulting in optimization of energy efficiency and infectious disease control. Ceiling discharge can be used (with adherence effect or Coanda effect) along with demand controlled ventilation rates to achieve significant capital cost savings through the reduction in size of air handlers, ceiling plenum height, heating and cooling plant and associated back-up generation and mechanical room dimensions.

Greg Allen, P.Eng., LEED® AP
Senior Associate, Rivercourt Engineering Inc

Greg has worked on advancing sustainability for over 50 years as a designer, builder, community planner, inventor, researcher, and consultant. He worked for HOK as their sustainable design strategist for 3 years and is currently a Senior Associate of Rivercourt Engineering Inc., formerly Sustainable EDGE.  

Greg has designed dozens of displacement ventilation systems over the past 40 years and he has been on several ventilation and energy related CSA committees.  Greg’s goal is to develop a prescriptive path for applying displacement ventilation in healthcare facilities.  Greg is the primary author of the Displacement Ventilation Emergence in Healthcare (DiVE) research deliverables.

 

 

 

 

Alex Hutton, P.Eng., CEM, LEED® AP

Founding Principal, Swordfern Strategic Sustainability

Alex specializes in sustainability and change management with a focus for over ten years on energy and carbon management within the healthcare sector. Alex’s 20+ year career since graduating from Environmental Engineering has evolved from being primarily technical towards focusing increasingly on the non-technical barriers to change.  This led Alex to initiate a new learning curve towards developing the ability to apply a Regenerative (or Living Systems) approach. This process continues to foster humility while simultaneously affirming long held principles, such as Alex’s motto: “Innovation through Collaboration”.

Alex has been an advocate of Displacement Ventilation for decades and has participated in the Energy Modeling aspect of two DV projects in the BC Healthcare sector.  Alex is the Project Manager for the DiVE project.

 

Tariq Amlani, P.Eng., LEED® AP
Vice President, Mechanical Engineer, Stantec

Curiosity is Tariq’s strength—an innate ability to tackle a challenge from multiple angles to uncover the best solution. A Mechanical Engineer with two decades of experience, he is a collaborative leader, and has played a pivotal role in the delivery of some of the most complex healthcare projects in North America, including North Island Hospitals Project and the Kelowna Vernon Hospitals Project. He is an active volunteer in the Buildings Engineering Industry, serving as past Governor with the ASHRAE BC Chapter and Chair of the CHES Corporate Committee.  

Tariq is global health care engineering lead for Stantec and has a wealth of experience designing healthcare facilities with DV.  Tariq is a key partner and contributor to the DiVE project.
