Keeping air safe has never been more important. Now that we are in the next normal, it is critical that the air we breathe in shared indoor spaces is healthy and safe for continued occupancy. Are we ready to face this challenge and mitigate airborne exposure risk indoors? Welcome to Healthy Air, a podcast that talks about the future of buildings and how to keep air safe and healthy.

“I’m not a doctor. I’m not an architect. But getting those two fields together helped bring forth an understanding of better indoor environments and the impact on human health.”

“Delos developed the WELL Building Standard to connect the built environment with the impact on respiratory, cardiovascular, immune, cognitive, digestive, and sleep health outcomes.”

“Health and wellness innovations have been infused into just about every consumer product category. Why not real estate? The homes we buy, the offices we spend 8-10 hours a day in.”

“We saw the LEED playbook with regard to environmental sustainability and wanted to take the best components of that and replicate it for human or biological sustainability in WELL.”

“This was an economic value proposition that happened to come with a tremendous societal platform. Using our real estate to introduce preventative medical intentions seemed obvious.”

“Human health and wellness in the built environment needs to be positioned as a right, not a privilege.”

“Well Living Lab is a 50/50 founding collaboration between Mayo Clinic and Delos, a research facility driving evidence-based health and wellness in the built environment.”

“Through the years, we’ve learned that indoor air quality tends to be two to five times worse than outdoor air quality. You’re not hiding from pollution by going inside.”

“We built a classroom with desks, chairs, manikins and cough simulators with top aerosolized particle experts in the world to scientifically test pre- and post-intervention efficacy.”
