Jonathan Woolley is a PhD student in Architecture at UC Berkeley. He earned a M.S. in mechanical and aeronautical engineering from UC Davis in 2008. Since 2004, Jonathan has been involved in a wide variety of research surrounding energy efficiency in buildings. He has specialized in the design, commissioning, demonstration, monitoring and evaluation of climate appropriate hybrid cooling systems. Other aspects of his research have included design of zero net energy homes, ground coupled heat pump systems, heat recovery, and advanced building ventilation strategies. Jonathan has developed new open source modeling tools for hybrid air conditioners, and holds the patent on a tracer gas airflow measurement system developed at UC Davis. At Berkeley, Jonathan is focused on the energy and comfort implications of radiant cooling strategies. In particular he is focused on performance optimization for radiant buildings throug design and control of natural ventilation systems, hybrid supplemental air cooling systems, low energy chilled water plants, and heat recovery. Beyond advancing state of the art technical solutions, Jonathan’s work embraces behavioral, economic, and policy opportunities as integral aspects of a pathway to sustainability in the built environment.
