Ventilation and IAQ

This past May I wrote in the Back2Basics column about the design intent of a small city school system that chose to invest in an annual contract for a temporary air-cooled chiller for special events and emergency crisis shelter center.

While travelling in Europe to the Indoor Air 2016 conference in Belgium, I had the opportunity to discuss a largely unspoken shift in the management of IAQ with a like-minded colleague, Dr. Walter Hugentobler from the University of Zurich, Switzerland.

Like several industries, if HVAC makes real headlines in national publications, it’s probably because something bad happened.

Spot exhaust is a unique design engineering challenge. The 2015 ASHRAE Handbook – HVAC Applicationscovers a broad spectrum of applications in just about all the comfort applications (chapters 1 through 13) and industrial applications (chapters 14 through 33) with personal safety an integral part of chapter 32. But spot return air doesn’t get much press in ASHRAE.

In our daily lives, we humans move through a sea of microbial life that is seldom perceived except in the context of potential disease and decay (L. Feazel 2009). 

A higher education campus presents an extensive amount of variables that can drastically impact the requirements of the indoor environment.

Last summer, CJ Automotive in Butler, IN, decided it was high time to replace its 40-year-old inefficient steam boiler system.
