Cx Associates Joins Global Community Mobilizing to Fight COVID-19

By Lauren Hagen on May 26, 2021 10:00:00 AM

Two weeks ago, Cx Associates made a donation to COVAX, the vaccine procurement and supply operation led by UNICEF to ensure “global equitable access to COVID-19 vaccines”. By joining UNICEF’s Humanitarian Circle, the donation will support UNICEF’s campaign to secure two billion COVID-19 vaccine doses delivered to over 180 countries worldwide. Cx Associates was compelled to act swiftly and support this cause, recognizing that health for everyone, everywhere is imperative to justice and equity.

Creating a Positive Remote Work Culture

By Eric Hauser on May 19, 2021 10:00:00 AM

Cx Associates was obviously not alone in shutting down our main office in Burlington, Vermont in March 2020 as the coronavirus pandemic hit the United States. Employers across the country shut down their offices and told their employees to work from home for the foreseeable future. Last summer, Cx Associates took measures in our office to enable a slow (and optional) return to working in the office – we constructed plastic barriers between workstations, installed HEPA air filters at each desk, and mandated mask use when not at one’s desk. But one year later, we are still very much a distributed team; we have one employee who already worked remotely, and many others who either prefer to work from home when possible and/or are not yet comfortable going back to the office.

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’ve 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.

COVID-19 Water System Recommendations for Vacant Buildings

By Katie Mason on Dec 17, 2020 2:59:06 PM

Throughout the COVID-19 crisis, HVAC system recommendations have been a primary focus because of the impact they can have on mitigating the spread of the virus inside buildings. Since we saw a period of time when many buildings were completely vacant and unused, it’s important to ensure your water systems are also safe for occupants before reopening. The concern here is not the spread of the COVID-19 virus, but harmful pathogens such as Legionella (bacteria that can cause Legionnaire’s disease) that can grow in stagnant water.

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.

To Return or Not to Return: Considerations for Reopening the Office

By Rachael Straub on Aug 12, 2020 10:15:00 AM

COVID-19 has turned our world upside down. From what we’ve learned about the transmission of COVID, spending time in an enclosed space with others is ill advised, and social distancing means working from home and homeschooling. I’ve been doing the former since March, even though Cx Associates’ offices reopened in June. Reopening the office was not an easy choice to make, as was my decision to remain at home, and I thought I’d write a bit about it.

Reopening Schools: Understanding and Prioritizing HVAC Preparedness

By Eveline Killian on Jul 6, 2020 10:15:00 AM

The prospect of reopening schools under the new CDC guidelines in response to COVID-19 can be overwhelming for facilities and administrative personnel. In addition to increased surface cleaning, hand washing, maintaining six feet between classroom desks, and wearing face masks, the schools are faced with making decisions on how to best operate their HVAC equipment. As much as the world is trying to help them with these decisions, the HVAC guidelines from the CDC and ASHRAE are all encompassing; it is difficult to identify which measures are applicable and even more difficult to prioritize the measures under a school’s constrained budget. This may overburden an already burdened school facilitator.

Current Considerations for School Re-opening

By Tate Colbert on Jul 2, 2020 10:00:00 AM

As we are all learning to adjust to life with COVID-19, many areas are considering re-opening schools for the coming school year. Although many teachers are finally starting to unwind into a stranger-than-usual summer break, now is the ideal time to get a jump on adjustments to school operations to make in-person education as safe as possible for students, faculty and staff alike.
