Speaker(s)  

Marwa Zaatari, PhD

 

Dr. Marwa Zaatari is Partner at D ZINE Partners and co-
Chair of enVerid Systems Advisory Board. She leads the
research and development of “Air as a Service” around
heat exchanger coils, ventilation, filtration, and IAQ
measurements. Her work continues to advance building
science methods in assessing performance-based
procedures to design and operate buildings to optimize
energy and people efficiency.

Dr. Zaatari is an ASHRAE Distinguished Lecturer and a member of several ASHRAE Committees,
a member of the ASHRAE Epidemic task force, Voting Member of Standard 62.1, Chair for
TRG4 Indoor Air Quality Procedure, Vice Chair of MTG.HWBE Health and Wellness in the built
environment, Vice Chair of TC2.3 gaseous removal contaminants, Voting Member Standard 145.2
laboratory test method for gas-phase air cleaning systems, IAQ2020 Conference organizer, LEED
Committee member, and ex-Chair of LEED IAQP Working Group. She also serves on the USGBC
board.
Dr. Zaatari has extensive experience in identifying and quantifying the sources, fate, and transport
of indoor air pollutants, building energy and environmental management, assessing performancebased
procedures of HVAC ventilation and air cleaning, and developing and applying models for
energy efficiency, indoor air quality, exposure assessment, and economic impacts of indoor air
pollution. Previously, Dr. Zaatari was Vice President of Building Solutions at enVerid Systems since
2015. She leads the design of ventilation and filtration/sorption systems in buildings, integration
into HVAC systems, and was responsible for managing customer-site installation and ongoing
operations and field service.
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.

Presentation
Summary
  This presentation provides an overview of air cleaning to minimize infectious diseases spread using ASHRAE COVID-19 filtration and disinfection framework. How to select particulate filters, air cleaners, and how to determine coil cleaning frequency and design considerations with respect to pressure drop, efficiency for different particulate size, by-pass, clean air delivery rate, and by-products will be reviewed. Different approaches using one or combination of control methods will be compared from energy and indoor air quality impact.
