Christian Kohler is the department head for Building Technologies at Berkeley Lab. For over 20 years he has been involved in all aspects of building energy efficiency research such as simulation, measurement and technology development. He has been deeply engaged in software development for various windows related tools, e.g., THERM, WINDOW, and Optics5. He has also led the development of new technologies for highly insulating and dynamic windows. His activities include algorithm development, user support, training, developing embedded controllers and experimental work on highly insulating and dynamic windows. His major work with industry has included being an elected Member of the Board of Directors of the National Fenestration Rating Council and the past Research Chair and Committee Chair Fenestration Technical Committee, American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE).

Prior to that he was working at the LBNL Infrared Thermography research facility.  He received his Masters degree in Building Physics in 1997 from Eindhoven University of Technology in the Netherlands.
