@moog77 This is a complete misinterpretation...and lack of understanding of the confounding factors. Perfect correlation would mean that every absence would be down to sars cov 2. Which it will never be because kids are absent for several reasons.

[Christina Hopfe 🇺🇦 @CHopfe]

@moog77 This is based on a numerical model by the @maxplanckpress institute. Of course, this is based on (validated) assumptions and on an infected person in the room. What is important here is not the absolute risk but the relative risk from one room to the other.

[LET'S AIR @nousaerons]

1,200 classrooms in Austria were monitored to analyze their indoor air quality. As in many countries, 75% of the classrooms have poor air renewal. The study conducted by @tugraz represents a huge amount of work, we strongly recommend reading the report https://t.co/VSK6dfecmO

City of Münster wants to dispose their 1188 air filters in schools, worth 2 mill Eur because they don’t need them anymore. Please send them out to other school regions before disposing of them, think of others.

"Disentangling the underlying issues around the housing supply crisis from the smokescreen thrown up by the house-building industry is vital...."

Will better environmental standards mean fewer homes?

Read @PassivhausPlus' response (p. 14 of today's @heraldscotland) to Homes for Scotland's calls for the Scottish Government to 'pause & review' the Scottish #Passivhaus equivalent policy.

Great to hear the upbeat and informative keynote speech from @AnnMarieFallon_ @ArchitypeUK at #ISEC in #Graz today. Speaking about regenerative design approaches and the vital role of whole life carbon in the net zero equation.

[Australian Academy of Science @Science_Academy]

The average Australian spends about 90% of their time indoors. While indoor air quality is considered a serious risk to public health worldwide, many countries—including Australia—do not have indoor air quality standards.  ...

@robertofner @igoe_at Vielen Dank für den Hinweis. Wir wissen bereits darüber Bescheid und sind im Prozess eine kleine Anzahl der Sensoren zu rekalibrieren, inkl. diesen.

Genau diese Erkenntnis ist so wichtig!
#SaubereLuft ist nicht selbstverständlich und ohne dauerndes Tun auch nicht vorhanden!

Nice to receive some positive feedback... School director in one of our 120 #impAQS project schools thanked us saying she wasn't "aware how fast air quality can worsen in classrooms and how important regular ventilation is" @tugraz #ibpsc @igoe_at #BMBWF @PassivhausPlus
