With entire buildings, and even campuses, being shuttered for months on end, you can’t simply reopen a closed building and assume it will be business as usual. In reopening closed buildings during – or after – the pandemic, how building owners and maintenance staff manage the essential building functions of indoor air quality and potable water can have an enormous impact on the health and safety of tenants and visitors.

## [100% Outside Air - Is it Really One of the Best Solutions for Flushing Buildings?](https://www.newmanconsultinggroup.us/green-building-blog/does-100-outside-air-flush-buildings)

In the age of COVID, we have to look at all available - and *viable *- options for occupant safety.

To help slow the spread of the coronavirus, ASHRAE, CDC (Centers for Disease Control and Prevention) and WHO (the World Health Organization) currently recommend running HVAC systems for a *minimum* of 4 hours (but preferably more) on a daily basis with 100% outside air (OA) to “flush out” the virus. I would love to be 100% on board with this recommendation all year round. But I’m not.

[Some estimates](http://www.paragoncontrols.com/pdf/Whitepapers/Cost%20of%20Poor%20IAQ.pdf) place the cost of poor indoor air quality (IAQ) to the United States' economy at **$200 Billion in today’s dollars**. In the age of COVID-19, [good IAQ](https://www.newmanconsultinggroup.us/green-building-blog/topic/indoor-air-quality) as we have known it is no longer enough. (Updated chart, 2/25/21)

## [Three Coronavirus Prevention Techniques for Your Building - a Comparison](https://www.newmanconsultinggroup.us/green-building-blog/coronavirus-prevention-techniques)

(updated chart, 2/25/21) As those of us in the building management and maintenance field prepare to “re-open” buildings, the health and safety of our tenants, guests, patients, staff and residents remains top-of-mind. Soon the general public will leave the comfort and safety of their homes where they have been limiting human contact for weeks, and venture out into the world with other people.![guy with cold](https://www.newmanconsultinggroup.us/hs-fs/hubfs/images/Stock,%20Blog%20and%20Presentation%20Images/guy%20with%20cold.jpg?width=262&name=guy%20with%20cold.jpg)

We must be prepared for them so they can feel safe when returning to shop, work and play in “the new normal.”

Nothing about building maintenance will be normal – perhaps for quite a while.  Every commercial building in the US and probably in most industrial nations, is now taking – or should be taking – extra precautions to ensure safety. People should feel safe going back to work, and building owners and managers must enact measures to both ensure safety and prevent, or at least minimize, potential litigation.
