Back in 1980, I attended my first ASHRAE winter meeting, and yes, I am aware that some of you readers weren’t born then, but I digress. In 1980, I was invited to present a seminar and introduce the dual fan-double duct (DF-DD) air handling system conference to attendees of that semi-annual conference. I also sat in on my first TC 9.01 technical committee session to advocate this DF-DD concept get published in the next ASHRAE Systems and Equipment Handbook in 1984.

While sitting in on the TC 9.01 meeting, it became obvious to me that if this “better than sliced bread” HVAC concept was to make it to the pages of the 1984 handbook, I needed to champion the revisions to the then chapter 3 on all air systems (now chapter 4 air handling and distribution) and thus my commitment to ASHRAE at a national level began.
