For the fifth anniversary of Urban Green Live, we returned to our very first guest: Dr. Joe Allen, Director of Harvard’s Healthy Buildings Program and Associate Professor at the Harvard T.H. Chan of Public Health.

In this episode, Dr. Allen reviews what we’ve learned since the COVID-19 pandemic emerged five years ago and discusses the latest trends for designing healthy buildings. Learn about recent improvements in Indoor Air Quality (IAQ) sensor technologies, new research about IAQ’s cognitive impacts on creativity, healthier building materials, and more!
