School Airflow Testing and ASHRAE 62.1

By Jamie Hand on Dec 23, 2020 10:00:00 AM

Over the last few months, Cx Associates has helped a number of schools throughout Vermont test their ventilation rates. As we’re discussed in previous blog posts, providing adequate ventilation rates is an important part of providing good indoor air quality (IAQ), both during the pandemic and normal times. While most buildings were designed to meet a ventilation standard, there are numerous reasons why rooms may not meet the current ventilation recommendations. In most buildings, measuring airflow is really the only way to know that you meet the recommendation.

After an early morning departure and a snowy drive, my colleague and I arrived onsite to test, among other equipment, a packaged rooftop air handling unit with factory controls. At first, the unit appeared to check all our boxes, but as we dug into the details, it became clear that this would be a very expensive heating system to operate. This blog entry is about factory controls and the importance of getting into the weeds to identify issues like the one we found with this rooftop air handling unit.
