November Program: Health-Associated Infections and Indoor Air Quality

As new research clarifies how essential the built environment is to patient healing and employee health and productivity, Dr. Taylor will communicate clear and up to date research on how indoor air management relates to patient healing, length of stay, and hospital profits. Given the exorbitant cost of healthcare, the frightening increase in antibiotic resistance, and the epidemic of patient harm from new infections, these insights offer exciting new tools that cannot be ignored. In addition, this study shows that the current focus on hand hygiene and surface disinfection to decrease transmission of infections will never be adequate without considering the added dimension of indoor management. For those still unconvinced about the value, the business case for these interventions will be presented. Best of all, these findings apply to all building types, not just hospitals.


Presenter: Stephanie Taylor, M.D., M. Arch

Dr. Stephanie Taylor received her MD from Harvard Medical School, Boston, Massachusetts in 1984. For the next several decades, she practiced clinical medicine and did academic research in cellular growth mechanisms.

During this time, she became increasingly concerned about patients who were harmed by new infection during their in-patient treatment. Determined to gain a better understanding of the impact of the built environment on patient well-being, she returned to school and obtained her Master’s Degree I Architecture and Engineering from Norwich University in Northfield, Vermont. After working for several years in a healthcare design architecture firm, she founded Taylor Healthcare Consulting, Inc., in order to focus on designing, building and maintaining hospitals to better support patient healing. She quickly learned that many of the building and indoor air characteristics that affect people in hospitals also influenced the health of all people in buildings.

Dr. Taylor is currently working at the intersection of architectural design, indoor air management, the microbiome of the built environment and occupant health. She finds the impact of buildings on our health startling! Managing the built environment and indoor air with the goal of decreasing diseases from acute infections to chronic inflammation to cognitive impairment, is a very underutilized yet powerful approach to disease prevention. She finds that her physician insights and biological research helps her understand the science behind the interaction of buildings, human physiology and energy consumption.

Dr. Taylor has designed hospitals globally, from the United States to Papua New Guinea to Vietnam. In addition to her Taylor Healthcare Consulting work, she is a member of the Harvard Medical School Incite Health Fellowship. This program brings together multidisciplinary teams from across the US, trains them in design thinking and entrepreneurship, and gives them the tools and resources to guide the future of medical care.

To communicate her work and understanding about the fascinating convergence of human health, microbiology and architecture, Dr. Taylor writes monthly columns and bi-annual feature articles for Engineered Systems Magazine and publishes in other healthcare journals. She is an active member of ASHRAE, ASHE and national and international medical associations. When not working elsewhere, Dr. Taylor lives in beautiful Stowe, Vermont with her husband and eight dogs. One of her favorite activities is skydiving, which she finds is great practice for staying outside of her comfort zone!

ASHRAE La Crosse History for 2020 CRC

La Crosse Area

The La Crosse chapter of ASHRAE has a long tradition and we want that to be on display for everyone to see, even if they can’t come see our display in person this year. So, this post contains our most recent chapter history display and a presentation on the history of Trane TRACE software that was later published in a paper in ASHRAE Transactions, authored by our previous chapter historian, John Sustar. Enjoy!

September Program Video

If you would like to see the September Program in its entirety, have I got the link for you! The La Crosse Chapter of ASHRAE has its own Youtube channel where you will be able to find future program video archives as well. 

Eric Sturm gave a presentation about indoor agriculture, how cooling requirements differ from typical indoor spaces, HVAC system designs, their pros and cons, load calculations, and ventilation requirements. 

Check out his presentation here.

September Virtual Program: Indoor Agriculture

Indoor Agriculture

Presenter: Eric Sturm

Please join us this month while we kick off our 2020-2021 La Crosse Area ASHRAE virtual program schedule. We have spent some time this summer putting together an exciting list of presenters and topics for the upcoming year that our audience can enjoy from the comfort of wherever they choose. 

In this presentation, Eric will provide an overview of indoor agriculture and juxtapose it with comfort cooling. He’ll also review common load calculation methodologies and the determination of proper supply air conditions. Finally, he’ll review several common HVAC systems and their advantages and drawbacks.

About the Presenter

After graduating from the University of Wisconsin – Platteville in 2006 with a Bachelor of Science degree in mechanical engineering, Eric began his career at Trane. In his current role as an applications engineer, Eric’s areas of expertise include acoustics, airside systems, indoor agriculture, and indoor air quality. Prior to joining the applications engineering team, Eric spent several years in the Customer Direct Services (C.D.S.) department as a marketing engineer and product manager for the TRACE™ 700 load design and energy simulation application. As a C.D.S. marketing engineer, he supported and trained customers globally.

He is currently involved with ASHRAE as a representative on Members Council and member of the “indoor agriculture” and “sound and vibration” technical committees. Eric is the recipient of a Young Engineers in ASHRAE Award of Individual Excellence for service to the La Crosse Area Chapter and nationally recognized with an ASHRAE Distinguished Service Award.

March Program

HVAC Rules of Thumbs for Troubleshooting
Presenter: Erich Binder, ASHRAE Distinguished Lecturer

This presentation will provide some common Rules of Thumb for Troubleshooting HVAC&R Systems.

  • Rules of Thumb are abbreviated short cuts, time savers, and approximations.
  • Each is a quick estimation of what most systems should do most of the time, but remember that none of these numbers are infallible.
  • The rules are not cast in concrete.
  • Rules of thumb usually assume certain normal design and operating criteria, which are not always present.
  • The rules are not to be used for system design purposes. Rather, they are the result of carefully studying good system designs.
  • Technicians and engineers, can benefit from using Rules of Thumbs for estimating and solving operational problems.
  • They do not always apply to every system, nor do they work in every circumstance.
  • It is expected that the engineer or technician using them is a professional who can use reason and exercise caution in their application.


About the Presenter

Erich Binder is an independent engineering consultant with extensive experience in the sustainable design of commercial, institutional, industrial and cold climate heating ventilation & air conditioning (HVAC), plumbing, fire suppression & specialty mechanical systems. Erich is also a certified risk manager with over 20 years of process safety, loss prevention, industrial hygiene, health & safety engineering and auditing experience.
