The Future of IAQ
W
e are likely in the midst of another paradigm shift.
Those are the key words from an article written by Max
Sherman, Ph.D., Fellow/Life Member ASHRAE (page 42). It
hits at the roots of indoor air quality, which is fundamental
to who ASHRAE is, as Sherman notes. His article, backed
by research and studies, covers the evolution from the fi rst
paradigm-ventilation rate-to the emerging harm paradigm. ASHRAE
Standard 62.1-2022's Indoor Air Quality Procedure (IAQP) uses a hazard
paradigm, using data to differentiate between hazard and harm. Make
sure you check this out.
Page 34 brings you an article based on results of tests from a zoned

traditional ducted variable speed heat pump and a multisplit heat pump
in a test home located in a hot and humid climate zone.
Our most recent ASHRAE Journal Podcast episode hits on the transition to
low global warming potential refrigerants. ASHRAE staff member Ryan
Shanley hosted the podcast featuring Stet Sanborn, AIA, Member ASHRAE,
and Douglas Reindl, Ph.D., P.E., Fellow ASHRAE. Search all podcast
platforms to hear them discuss the transition from high GWP to ultralow
GWP refrigerants; the marketplace for A1, A2 and A3 refrigerants; and
how this phase of fl ammable refrigerant use impacts ASHRAE Standard
15, Safety Standard for Refrigeration Systems, and ASHRAE Standard 15.2, Safety
Standard for Refrigeration Systems in Residential Applications.
By the time you read this, hopefully we met and discussed potential article
and podcast contributions at a successful ASHRAE Annual Conference in
Indianapolis, my third such event to attend as Journal Editor.
Many notes from me in this space going forward will detail what ASHRAE
Journal needs. We are near the end of planning our 2025 editorial calendar.
Our January issue will be on display at the ASHRAE Winter Conference
and the AHR Expo. Articles on fundamental topics for engineers and
contractors are welcome. Early next year, we plan to hit on data centers,
cybersecurity, ventilation and more, and we'd love to read about your fi eld
studies in places like schools, hospitals, kitchens and other residential
applications.
You can help your peers by writing about good/better/best practices and
how to avoid pitfalls.
If there are topics you'd like to see us cover more, email me at
dchamplin@ashrae.org.
