Guest Bio

Christian Weeks is the CEO at enVerid Systems, Inc and is a leader in indoor air quality and energy efficiency. With over a decade of experience, Christian has a passion for helping buildings achieve their energy efficiency and indoor air quality goals through smart investments in HVAC systems and improving air cleaning technologies. Christian is a graduate of Dartmouth College and the Harvard Business School.

Marwa Zaatari is partner at D ZINE Partners & co-chair of enVerid Systems Advisory Board. Dr. Zaatari is a board member at the US Green Buildings Council, an ASHRAE distinguished lecturer, and a member of several ASHRAE committees. Dr. Zaatari earned a PhD in architectural and environmental engineering from the University of Texas at Austin with a focus on the built environment and a master’s degree in engineering management from the American University of Beirut Lebanon with a focus on energy management.


In this episode, Christian Weeks and Dr. Marwa Zaatari have a discussion with Erik Malmstrom about the recently released white paper, How to Achieve Sustainable IAQ: A Roadmap to Simultaneously Improving IAQ & Meeting Building Decarbonization and Climate Resiliency Goals. Not only do they discuss the steps outlined in the paper for achieving sustainable indoor air quality, but they also talk about the evolution of ASHRAE guidance, innovations and new technologies to achieve IAQ goals, and the bottom line of cost effectiveness of good and sustainable IAQ.

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. Keep up with the latest industry trends, latest technologies, and regulatory changes with your host, Erik Malmstrom, industry experts, and the SafeTraces team here on Healthy Air.

"Our goals at enVerid Systems with our recent white paper about sustainable indoor air quality are to deliver good indoor air quality as efficiently as we can." – Christian Weeks

"There are ways to combine cost-effective air clean technologies with optimized ventilation rates to achieve energy and indoor air quality goals." – Christian Weeks

“Our focus at enVerid is on using sorbent filters to capture gases from indoor air, and on combining these sorbent filters with particle filters and other air cleaning technologies to address the three pillars of IAQ: gases, particles, and pathogens.” – Christian Weeks

"People become very comfortable with the idea that dilution is the solution to pollution, but at enVerid, we wanted to provide a verifiable way to ensure good indoor air quality." – Christian Weeks

"The white paper How to Achieve Sustainable IAQ: A Roadmap to Simultaneously Improving IAQ & Meeting Building Decarbonization and Climate Resiliency Goals received encouraging feedback in the hopes of improving indoor air quality while saving energy as well." – Dr. Marwa Zaatari

“Upgrading filtration is far less energy intensive than increasing ventilation to reduce exposure to infectious aerosols: on average upgrading filters costs 3 cents/ft² versus increasing ventilation costs 55 cents/ft² to meet the same exposure reduction goals.” – Dr. Marwa Zaatari
