The New York Times -“The C.D.C. is urging communities to reopen schools as quickly as possible, but parents and teachers have raised questions about the quality of ventilation available in public school classrooms to protect against the coronavirus.We worked with a leading engineering firm and experts specializing in buildings systems to better understand the simple steps schools can take to reduce exposure in the classroom. These simulations offer examples based on specific inputs, but they show how ventilation and filtration can work alongside other precautions like masking and social distancing. “Improving ventilation is only one part,” said Mark Thaler, who is an expert in school spaces with the design firm Gensler. “It has to stand with all the other C.D.C. guidelines in order to really safely reopen.” Step inside a classroom with augmented reality to see where contaminants spread…”
