“We shouldn't expect the world of our potted friends.” Kavita Kumari, Associate Director, spoke to @BBCNews about why plants are not an all encompassing solution to improve indoor air quality.
Stop focusing on cleaning surfaces and spraying toxic disinfectant in indoor spaces. Instead focus on improving ventilation in poorly ventilated environments. Or moving activities outdoors while you can. Transmission happens through the air, much more than on surfaces.
What is the impact of Covd-19 on the design of HVAC systems for future buildings? @cibsejournal asks 4 building services engineers how system specification might change as a result of recent guidance in the July edition, out now. https://t.co/5q5dWG3OJq
This #WorldEnvironmentDay we are pleased to announce the Steering Group for our #NatureBasedSolutions Framework - great to have an impressive group of industry leaders on board! Find out more about the Nature-based Solutions programme here: https://t.co/2uNsSqebVb
Architects need to consider different scenarios for what the climate will look like in 50 years when they design buildings, according to a report by the British Council for Offices (BCO) https://t.co/2IunrK0Vjk
A study estimates that a single minute of loud speaking generates at least 1,000 covid-containing droplets, and these droplets stay airborne for longer than eight minutes, and sometimes as long as 14 minutes. https://t.co/UaHshHD82z
The #COVID19 "6-feet rule" falls apart with even a slight breeze

based upon extensive simulations of coughing and airborne droplet transmissions (e.g. saliva can travel 18 feet in 5 sec w/ a bit of wind)
"The goal is to minimize risk, and we can get there using a LAYERED DEFENSE approach by applying what is known in public health as the HIERARCHY OF CONTROLS."

How to reopen buildings safely, when the time is right, is the trillion dollar question.
I explain an approach, grounded in science, for how we can do this safely 👇

New* findings on aerosols released during speech
[*New in the sense that this paper specific to SARS-CoV-2 was just released, but we've known this for about 75 years]

After choir practice in Skagit County, #Washington, 52 members became ill with #COVID19 symptoms. COVID-19 spreads easily between people. Avoid groups, stay at least 6 feet apart, and wear cloth face coverings to reduce spread. Learn more from @CDCMMWR: https://t.co/NJ2bfA6QPw.
