The First Four Healthy Building Strategies Every Building Should Pursue to Reduce Risk from Covid-19
----
The Lancet Covid-19 Commission
Task Force on Safe Work, Safe School, Safe Travel
🧵
1. Commission (give your building a tune-up) 2. Maximize outdoor air 3. Upgrade filtration 4. Supplement with portable air cleaners
1. Commission or Recommission Building Systems
2. Maximize outdoor air
3. Upgrade Air Filters to MERV13
4. Supplement with portable air cleaners, where needed
The #FirstFour represent key actions that represent the most effective, fundamental steps toward promoting healthier indoor environments and reducing the risk of airborne infectious disease transmission indoors.
Why act?
--> Airborne transmission is the dominant mode of transmission
--> Reducing inhalation exposure reduces risk
--> Ventilation and filtration are key strategies
-->There are benefits beyond COVID-19

“(Personally, I would’ve liked to have seen schools open nationwide in fall 2020, with additional focus on rapid testing and improved ventilation.)”@dwallacewells
Yeah, same exact for me. The path to keeping schools open was so freaking obvious.
There’s this false notion that a healthy building is at odds with energy efficiency. We actually have existing technologies that allow us to conserve energy while improving indoor air quality.

—> We need to upgrade our filters to a higher standard, and these can be deployed without an energy penalty.
—> We can have higher ventilation rates, and instead of releasing that treated air-conditioned air out into the environment, we can recapture some of that with energy recovery ventilation.
SCHOOLS: I'm presenting today for a State DPH on steps schools can take on ventilation. Re-sharing some things I hope people find helpful (all available since summer 2020)
Simple #HealthyBuilding strategies: more ventilation, better filtration, portable air cleaners, VERIFY

But, as I've been saying since March 2020, you can't just say 'more outdoor air' without giving a specific target. My recs is 4-6 ACH.
How can I determine if my classroom is meeting these targets? We have a simple 5-step guide for how to do this.
