Why is Kitchen Ventilation So Important? With Dr. Iain Walker from LBNL

When you fire on a stove-top burner, whether it is electric, gas, or convection, many byproducts are released. This increase in moisture, gas, and other particulates is not only detrimental to the health of a building, but dangerous for human health as well.

To advance our knowledge on this topic, we invited building scientist and ventilation expert, Dr. Iain Walker, from Lawrence Berkeley National Laboratory (LBNL). Dr. Walker discusses strategies for controlling byproducts associated with cooking by focusing on kitchen ventilation.

Episode Guests: Iain Walker, PhD.

Iain Walker HeadshotIain Walker is a scientist at Lawrence Berkeley National Laboratory (LBNL). He has more than 20 years of experience as a building scientist and consultant, conducting research on energy use, ventilation, moisture, performance simulation, and commissioning/diagnostic issues in residential buildings. His current work focuses on retrofits, zero/low-energy homes and heating, ventilation, and air-conditioning (HVAC) systems in residential buildings through field and laboratory evaluations, modeling and simulation activities, and standards setting. Dr. Walker is the task group leader for the American Society of Testing and Materials (ASTM) standards committees on building and duct system air leakage and sealant longevity. For the American Society of Heating, Refrigerating, and Air-conditioning Engineers (ASHRAE) he serves on National Standards committees for indoor air quality, weather, moisture design, and equipment air leakage. He also serves on Building Performance Institute (BPI) and Residential Energy Services Network (RESNET) Technical Committees, the Affordable Comfort (ACI) conference planning committee and provides leadership and technical input to many local, state, national and international bodies.
