World Trade Center Tenants Deploy Ecology by Phylagen™ to Monitor for COVID-19

By Phylagen | Phylagen

Returning to the office just got safer. Phylagen, a enterprise provider of biotechnology services that measure the health and safety of indoor air, today announced that Silverstein Properties, owner of three office buildings at the new World Trade Center, has deployed Ecology by Phylagen™, the first enterprise airborne virus monitoring service that can identify the presence of pathogens, including SARS-CoV-2, the virus that causes COVID-19.

Developed by world-renowned indoor microbiology scientists, Ecology by Phylagen™ is an end-to-end service that tests settled air samples for viral DNA/RNA from zones around an office or manufacturing space. The service is already active in 19 countries with client offices located in cities including New York, London, Berlin and Zurich. Ecology by  Phylagen™ can identify whether the inhabitants of a space are actively shedding a virus, even if they're asymptomatic. The easy-to-use software interface alerts property managers or tenants when a pathogen is found and whether it's at a level that requires action like quarantine. It's a non-invasive and cost-effective testing alternative.

Silverstein Properties is using Phylagen's services across 15 million square feet of office space, including the World Trade Center in New York City, as well as commercial properties in Philadelphia and Los Angeles. Through the biweekly monitoring service, Silverstein has been able to identify individuals who were asymptomatic carriers of the disease, thereby preventing the spread of an office outbreak and beyond.

"When we learned of Phylagen's pathogen monitoring service, we knew it would be an integral part of our return to office measures," said Guy Vardi, Chief Innovation Officer, Silverstein Properties. "We are deeply committed to keeping everyone in our buildings safe. This technology has already proven its incredible value during the Omicron surge and will become the new standard for indoor building safety plans."

"We expect modern buildings, especially the workplace, to keep us comfortable and healthy. We would never knowingly provide our employees with dirty drinking water. Why is it acceptable to provide them with unsafe air?" said Dr. Jessica Green, CEO and co-founder, Phylagen. "Right now, we're all focused on keeping COVID out of our workplaces, but the demand for healthy indoor environments won't go away after this pandemic. Phylagen is committed to getting us back to work today and future-proofing our buildings so none of us are ever in this position again."
