My #indoorairquality & #thermalcomfort lectures in a nutshell...this the stuff we need to teach #architects and #engineers but don't...neither of these fields are complete without understanding human factors. S/o @ashraenews 
One of the cool studies I talk about is particle emission from carpets and respiration by infants crawling across the floor...it's a real thing...s/o to Wu & Boor from Purdue
I also tall about the use of PET scans to observe the brain's response to skin heating and cooling...both critical in thermal comfort design.
How indoor air quality in schools affects student learning and health journalistsresource.org/education/indo…
COVID-19: Experts said #Canada’s #schools need better #ventilation in 2020.
Experts agree #indoorairquality in schools affects student learning and health.
Experts also agree that ventilation is key to helping quell the risk of COVID-19 indoors.
Have the Provinces acted?

@kprather88 I can share what I've been told so often over the years about why =>N95/FFP2 respirators/masks😷& filters may not "significantly" reduce⬇️ #AirPollution health risk. Some= valid points to consider:
1- health effects of varying concentrations of PM2.5 exposures aren't linear.

2- they share poorly-designed studies in which too little filter surface area/efficiency/air flow rate is installed to provide enough cycles (i.e., air changes) per hour through filters for the space. When this is pointed out, they reply "solutions must be affordable" 2/

When one highlights that affordability, while very valid, answers & takes us toward a policy question rather than simply answering "do filters work" to reduce exposure of occupants to outdoor/indoor #AirPollution, they continue to conflate the #IndoorAirQuality science 3/

We have a newly published paper on #IndoorAirQuality and it is #OpenAccess! This was a fun study and here’s a short thread on some of our findings. /1

We put a bunch of low-cost air quality monitors in four homes to measure concentrations of fine particulate matter (PM2.5) during the occupants' everyday lives. Each home deployment was about 10-weeks long.
Not all low-cost monitors behaved the same way. Some were much better than others. But they all performed better during background periods (no indoor sources) compared to when there were indoor PM2.5 sources, such as indoor cooking. 3/

Is humidity control just for warm-humid weather? Or can you grow mold in winter?
A little thread for the part of #energytwitter that hasn't seen the bigger picture of #buildingscience.

First, if you think you're immune to moisture & mold problems because your climate is dry in summer, let me invite you to take a look inside your fridge. What's inside that container in the back that you've forgotten for a couple of months.

Extreme example: Family in Kansas had a poorly insulated building enclosure. They kept the inside relative humidity at 50% while outdoor temperature was -5 °F.
Yes, that's ice on the walls & ceiling inside the house. Here are the details:

This is not to say all we need to do is electrify transport and build renewables, we should also be looking to radically reduce car ownership and miles driven, and to radically increase miles by 🚲 🛴 🚶♂️🚃 🚊 and 🚌.
Nails arriving tomorrow so time for a bit of cleaning before putting the floorboards down. Not much use in having the low-dust house (airtight and filtered fresh air through the MVHR) if there’s a load of dust right under the floorboards! #Passivhaus #EnerPHit
Making some more holes so I can measure exact distance between studs so @Drew_Carr_ can finalise the downstairs window sizes.

#ISESISIAQ2019 A. Hoisington studies interaction between nature, personal control of occupant, #indoorairquality and mental health. Surveyed 92 #Denver VA hospital veterans.
Found that no nature pictures, poor privacy and water damage all were associated with severe depression/PTSD/insomnia
