Woody Delp received a Ph.D. in mechanical engineering from the University of Missouri Rolla in 1995. His graduate work involved modeling how much ventilation (outside air) comes into variable air volume (VAV) systems as they operate across a range of climates and seasons. Woody grew up in Rolla working in a family-owned HVAC contracting business. In his dad’s business he worked in every capacity, from service calls at a young age, to designing and installing complex systems for local laboratories. HVAC is very much in his blood. Woody has been at LBNL since 1995 and has worked in various project areas involving HVAC systems, and how these systems actually operate in real buildings. His work has ranged from measuring duct leakage in light commercial buildings to understanding how pollutants move in large buildings. He is equally at home working with residential HVAC systems as well as systems found in the largest buildings.
