Indoor Air Quality (IAQ) Assessment Process and Report

By Katie Mason on Apr 8, 2021 10:00:00 AM

Cx Associates has posted several blogs about an HVAC systems’ contribution to keeping building occupants as safe as possible from the COVID-19 virus. But for some building owners and tenants, understanding what they have for an HVAC system and what they can do to make their systems better isn’t immediately known without some help from experts in this industry.

Ventilation Control Strategies During COVID-19: Why & How

By Eveline Killian on Jan 27, 2021 10:15:00 AM

Over the past several months, it has been proven that HVAC systems play a role in the mitigation of the spread of a virus like COVID-19. The first line of defense – personal masking and social distancing – is by far the most effective in mitigation, but we’ve learned a lot about HVAC’s contribution to keeping people safe indoors. My last blog covered the why & how of ventilation (fresh air). In this blog I want to focus on ventilation control strategies: why & how the industry evolved from pre-pandemic minimalization, to early-pandemic wind tunnel 24/7, to a common sense, balanced approach on ventilation control.

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.

Ventilation During COVID-19: Why & How

By Eveline Killian on Dec 9, 2020 10:00:00 AM

We’ve learned a lot about COVID-19, the spread of a virus, and the mitigation of the spread over the past several months. The recommendation of the first line of defense - masking and social distancing – hasn’t changed since this pandemic started in January 2020, but it seems like every other recommendation has evolved throughout these long months. In our business of HVAC, we have kept up with the industry and CDC recommendations on ventilation and filtration and have been active in assessing commercial and institutional buildings.
