Meet the Team

	Wanyu (Rengie) Chan, Ph.D., is a Research Scientist and Deputy Indoor Environment Group Leader in the Energy Analysis and Environmental Impacts Division at Lawrence Berkeley National Laboratory. Her work focus on characterizing indoor air quality and implications to human exposures in residential and commercial buildings. She recently completed a research project studying indoor air quality and ventilation in California classrooms, working in collaboration with UC Davis Western Cooling Efficiency Center. Dr. Chan serves as the point of contact for the Efficient and Healthy Schools Campaign. She also manages the U.S. Environmental Protection Agency sponsored IAQScience.lbl.gov website that summarizes the state of knowledge on indoor air quality and health. Dr. Chan earned her Ph.D. in Civil and Environmental Engineering from University of California, Berkeley in 2006.
	Carolyn Szum is a Program Manager at Lawrence Berkeley National Laboratory with 17 years of experience leading and managing domestic and international building energy efficiency market transformation initiatives, with specialized focus on building energy performance benchmarking and climate finance. Prior to joining Berkeley Lab, Carolyn was a Lead Managing Consultant at ICF where she supported the U.S. Environmental Protection Agency’s (EPA) domestic and international building energy efficiency programs, ENERGY STAR and eeBuildings. She has an M.A. in International Relations from The Fletcher School of Law and Diplomacy at Tufts University.

	Cindy Regnier, P.E., P.Eng., LEED AP, is Technical Leader for Commercial Building Systems at Lawrence Berkeley National Laboratory in the U.S., and Executive Manager for FLEXLAB®, the U.S. Department of Energy’s newest building technologies testing facility – the Facility for Low Energy Experiments in Buildings. FLEXLAB is Berkeley Lab’s series of experimental testbeds focused on RD&D of integrated systems and grid enabled controls. She also manages several research projects focused on deployment of low energy systems and technologies. These include the development of integrated systems incentive programs for utilities, and 2030 District scale solutions focused on small commercial, working with a number of U.S. cities. Prior to joining LBNL in 2009, she spent 13+ years on design of innovative, integrated HVAC systems, including AIA COTE Top 10, LEED Platinum buildings, and a 200,000sf carbon neutral science museum. Her Bachelor’s degree is in Mathematics and Mechanical Engineering from Queen’s University, Canada, and she holds professional engineering licenses in California and Ontario, Canada.
	Alexandra Johnson is a Senior Research Associate in the Indoor Environment Group at Lawrence Berkeley National Laboratory. She has a BSChE in Chemical Engineering and a Masters of Public Health with an emphasis in epidemiology and biostatistics. Alexandra previously worked as an engineer in industry and energy before moving into research and within the field of environmental health sciences. While at Berkeley Lab, her focus has been on air quality in various indoor environments.
	Tracy Washington Enger has worked for the U.S. Environmental Protection Agency in the Office of Air since 1994. In her current position in the Indoor Environments Division, she develops, promotes and implements education and outreach programs that protect public health from indoor environmental pollutants. She has worked for 20 years on building capacity for school districts across the country to create greener, cleaner, heathier learning environments by implementing the EPA Indoor Air Quality Tools for Schools (IAQ TfS) Action Kit. In addition to the IAQ TfS Action Kit itself, she has been instrumental in the development of a suite of products to assist schools in taking action to address IAQ issues, including newly developed guidance documents on preventative maintenance, websites, National and regional in-person training events, and series of professional training webinars.
	Andrea Suarez Falken serves as Director of U.S. Department of Education Green Ribbon Schools and ED’s Facilities, Health and Environment Liaison, in addition to overseeing the Recognizing Inspiring School Employees Award. Each of these are communications and outreach tools that respond to public requests for federal education initiatives that Andrea has built from the ground up. Andrea has been a career civil servant for over 10 years, beginning her federal tenure at the Department of Homeland Security. Early in her career, she taught and translated languages in France and Spain and worked at Georgetown University. She earned both of her degrees — a master’s from Georgetown University and a bachelor’s from Colgate University — with high honors. She is passionate about leveraging public engagement to inform useful federal policy.
	Sam Petty currently serves as the Commercial Buildings Integration technology manager for the Efficient and Healthy Schools Campaign. Sam has been supporting the Department of Energy in the Building Technologies Office (BTO) for several years. In the past, he worked with BTO as a contractor and an ORISE Science and Technology Policy Fellow. His past work at BTO included supporting Emerging Technologies' Technology-to-Market, Opaque Envelope, Windows, and HVAC&R Portfolios. Sam received his B.S. in mechanical engineering from the University of Colorado Denver in 2010. Prior to joining BTO, he has worked in the coal fired steam generation industry mitigating mercury emissions, as well as on precast modular construction projects.
	David Landman is an energy and sustainability expert with over 25 years of experience, including 20 years of EMIS experience working with big data analytics in educational, healthcare, life science, federal, commercial and industrial facilities. His experience includes analyzing and developing central plant, HVAC, and IAQ projects.
