#WHIAQ. @j_g_allen.

- Our indoor age is 0.9x(age).

- The person who manages your buildings (including your homes) has a bigger impact than your doctor
1/
- Standards for ventilation are bare minimums when they are actually followed.

- Give buildings a tune up.
Take pulse of buildings regularly (CO2).
- Increase ventilation
- Upgrade filtration
- Need Ventilation METRICS (YES!)
We have enough data to move now.
2/
- Need to make standards and codify so it reaches all people, not just those who can afford it (yes).

- Energy/IAQ tradeoffs if a false choice.

- IAQ is only part of Indoor Environmental Quality and safety and security.
3/
- Good IAQ protects your assets (people) and helps recruitment and retention.

- "Where has indoor air been in all of this?"

- Decisions today on our buildings will influence the health of future generations. 4/4

#WHIAQ. Innovations in IAQ

Stephanie Guerra. OSTP. Assistant Director for Health Security and Biodefense.

- Responsible innovation of technologies can help improve IAQ in a wide spectrum of indoor environments.
1/
@CorsIAQ. It is not going to require rocket science to improve IAQ. We have the tools to do it now. If we do it we will get better health outcomes. We need to make sure we don't leave any community behind. We need accessible tech for IAQ.
2/
@ShellyMBoulder We need to regulate IAQ as a public good like water (YES!!!). Once we view it as a public good the answers are there. We need standards, regulations and enforcement just like we do for water. We have the tools, we don't have framework to implement the changes.3/

#WHIAQ. Clean Air Benefits Everyone.

Taryn Williams. Ass. Secretary of Labor for Disability Employment Policy. Improving IAQ in schools, homes and workplaces is an issue of equity (YES). Those who vulnerable are more likely to be affected by poor IAQ.
1/
Kenneth Mendez. Asthma and Allergy Foundation of America. 25 Million Americans have Asthma and 4,000 people die per year (1:13 people). 5 Million children. Asthma is leading cause of missed school days. Cost is up to $82 billion (?). Need better IAQ to reduce triggers.
2/
@linseymarr Need to make it easier to experience good IAQ, by setting standards that schools need to meet. If the road is dangerous we lower the speed limit and have enforcement mechanisms.

#WHIAQ. Why improving IAQ makes good business sense.

Jordan Silberman. Monumental Sports (Capital One Arena in DC). Baseline post pandemic now thinks about more than just security. Created a system to track safety AND IAQ through building wide monitoring.
1/
Michele Schneider. Salesforce. 6 million sq feet management. Workplace design focused on well being in the past. Now IAQ is on the list and a core value.

Kevin Kampschroer. GSA. The only reasons buildings exist is to take care of people in them (YES).
2/
Kevin Kampschroer. GSA. Firing ranges do NOT have good IAQ. In control of 360 million square feet. Fell into the droplet trap. Need to use good cleaning products as they stay in the building. Biggest change is a vastly larger effort to test buildings/compile data.

#WHIAQ Schools. Alex Marrero. Denver County Public Schools Superintendent.

Jesus Jara: Clark County School District Superintendent.

(Lost the intro thread.... But both have districts that with 10,000s of staff/teachers and 90,000 plus students). 1/
- Clark County has 10,000 homeless students.

- Marroro. Funding and policy. Has spent $25 million on IAQ (MERV 13 filtration as standard and IAQ monitoring). What happens when money ends? Filters need to exchanged. 2/
- Marroro. Some relief funds have been used for things like bus drivers to alleviate shortage. Need to move IAQ changes into policy so it becomes part of regular funding.

- Marroro. Academic performance is tied to building performance which is tied to health performance. 3/

#WHIAQ. @ashishkjha

- Indoor air quality is the next front for public health.

- Drinking water improvement was a long term systematic change. We need the same effort for IAQ.

- It becomes harder to imaging how our health care system can manage respiratory diseases. 1/
- The single biggest structural change we can make to address respiratory transmission is to improve indoor air quality.

- We need health buildings, because we need healthy communities. 2/
- The benefits of IAQ improvements need to be seen.

- Today there is a new Whitehouse website on IAQ. whitehouse.gov/cleanindoorair/

#AAAR2022. Plenary: @IAQinGWN

- A story about filters....

- How to improve indoor air cleaner
1- Keep it dry
2- Source control
3- Ventilation
4- Air cleaning

- Filtration (air cleaning) has the shortest history. Only 50-100 years use in buildings.
1/
- ASHRAE standard 52.2 for filtration is only 23 years old.

- Measured CO2 and PM2.5 decay in a classroom that was supposed to be operated at 6 air changes per hour with ventilation and filtration. But it was actually at ~2 air change per hour.
2/
- Why does filtration fail to meet goals?

- Issue #1. Air has to get to the filter. For central heating homes the recirculating rate can range from 2-8 when the fan is on. BUT the fan can often only 20% of the time, with HUGE variation on the run time.
