Spencer Maxwell Dutton, PHD, completed his doctorate at the University of Nottingham, UK, on the topic of balancing energy use and IAQ in naturally ventilated commercial buildings, which included a school-based study of occupant window use behavior and IAQ. He worked as a building energy and daylighting consultant in London, before returning to Berkeley in 2010. His research at the Lawrence Berkeley National Laboratory includes modeling the potential energy savings of low energy cooling strategies, including natural ventilation; assessing how ventilation strategies affect human health outcomes; and model development of various novel HVAC systems and control strategies.
