    Henry Slack – Environmental Engineer, US Environmental Protection Agency (Retired)


    From 1991 to 2018, Henry Slack managed the Indoor Air Program for the U.S. Environmental Protection Agency (EPA), Region 4, which covers eight southeastern states. In this position, he offers expertise concerning indoor air to citizens or public agencies with questions on topics as diverse as mold, odors, ozone, carbon monoxide, air cleaners, ventilation systems, and secondhand tobacco smoke. The EPA program is non-regulatory. A frequent presenter at conferences, he wrote (with Janise Palmer) and presented “Elevated Radon in Concrete Residential Buildings” at the ASHRAE Indoor Air ’13 Conference in Vancouver, B.C.


    Mr. Slack had a temporary assignment to the CDC National Center for Environmental Health, Air Pollution and Respiratory Health Branch, in 1998, where he investigated the use of unvented residential heating appliances (which could lead to carbon monoxide poisoning). In 2004, he was appointed a Fellow through Partners of the Americas, and spent a month and a half in Barbados training and assisting staff of the Barbados environmental agency.


    In previous work, he was responsible for energy management programs for the U.S. General Services Administration, Region 4; designed rooftop air conditioning units for Seasons-4, Inc., a small manufacturer; and served as the Energy Coordinator at Fort McPherson in Atlanta.


    Mr. Slack earned a Bachelor of Science in Chemistry in 1974 from Southwestern at Memphis (now called Rhodes College) in Memphis, Tennessee, and a Master of Science in 1980 from Georgia Institute of Technology. He joined ASHRAE in 1988.


    Presentation Title:
    Ventilation Research: Is More Air Better for Us?


    Presentation Summary:
    Recent research by leading indoor air scientists clearly suggests health benefits may not level off until outside air delivery approaches 50 CFM/person.  While less outside air cuts energy bills, research suggests that additional outside air may pay for itself, from a reduction in symptoms and greater productivity.   Studies in schools have found statistically significant correlations between test scores and quantity of ventilation air.  A small study found CO2 levels of 1,000 and 2,500 ppm caused losses in the ability to make decisions.  The speaker will review all the recent ventilation research on all sides of the issue.
