Key Focus

  • (Outdoor air needs to be cooled, heated, humidified, or dehumidified based on the system; adding filters is less energy intensive but it could still require more powerful fans to push the air through.) For decades, engineers have focused on making buildings more energy efficient, and it's "hard to find a lot of professionals who are really pushing indoor air quality," Bahnfleth said. He has been helping set COVID-19 ventilation guidelines as chair of the ASHRAE Epidemic Task Force
  • But we also need more detailed studies to understand how specific ventilation levels and strategies will actually reduce disease transmission among people. This research can then guide new indoor air-quality standards from the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), which are commonly the basis of local building codes
  • If we are to live with this coronavirus forever -as seems very likely-some scientists are now pushing to reimagine building ventilation and clean up indoor air. We don't drink contaminated water. Why do we tolerate breathing contaminated air.
  • Modern buildings have sophisticated ventilation systems to keep their temperatures comfortable and their smells pleasant-why not use these systems to keep indoor air free of viruses too.
