Ventilation and IAQ

RSS

This past March and April, I wrote in the monthly column, Tomorrow’s Environment, about “How Much Is Too Much.”

In a partnership with 45 school districts, the University of Colorado Boulder, the Colorado Department of Health and Environment, and Attune has deployed the Attune indoor air quality (IAQ) systems in 369 school buildings across Colorado. 

The testing, adjusting and balancing (TAB) industry converged in St. Louis recently for the International Certification Board/Testing, Adjusting and Balancing Bureau (ICB/TABB) Conference.

Both models utilize proven beta attenuation methods to deliver accurate measurements of particulate mass concentrations.

The two organizations agree to the joint promotion of codes and standards at the local, state and federal levels.

Recent studies show that Improved air quality in classrooms has demonstrated an increase in test scores by 14%, increase attendance by 11% (classrooms with better air quality yield fewer sick days), and a 20% increase in attention span longevity.

Why is harm from air pollutants still so prevalent? There are several reasons.

The manual includes a revised chapter with sample test and balance report forms included for the end user.

SPAR is comprised of woven, knit, or non-woven structures where nonconductive yarns combine with conductive yarns that serve as electrodes.  When a voltage is applied to these conducting yarns, a non-thermal plasma (NTP) is produced.

While we manage IAQ to decrease exposure to airborne pathogens, such as SARS-CoV-2, we need to be extremely careful to avoid IAQ management that has the unintended consequence of suppressing our immune system, making us more vulnerable to infections, inflammatory diseases, and cancer.
