Energy Systems Laboratory

The Texas A&M Engineering Experiment Station’s Energy Systems Laboratory was first established on the A&M main campus as the Fan Testing Lab in 1939. Today it is one of seven stage agencies administered by The Texas A&M University System. The lab is affiliated with A&M’s Department of Mechanical Engineering and the College of Architecture, The Energy Systems Lab develops and transfers energy efficiency technology, specializing in field research such as:

  • Metering and modeling energy use in buildings

  • Optimization of heating, ventilation, and cooling systems, known as Continuous Commissioning®

  • Modeling and analysis of data collected, including calibrated simulation and measurement and verification of photovoltaic solar installations

David Claridge has been the director of the Energy Systems Laboratory since 2007.


Dr. David Claridge is the director of the Energy Systems Laboratory and the Leland Jordan Professor of Mechanical Engineering at Texas A&M University as well as being.a professional engineer. He holds a B.S. in Engineering Physics from Walla Walla College and M.S. and Ph.D. degrees in physics from Stanford University. He has been associated with the Energy Systems Laboratory since 1986 and is internationally known for his work on energy efficiency. He pioneered development of the process of existing building commissioning which is today generally recognized as the most cost-effective way to reduce energy use in buildings, and accounts for several hundred million dollars of engineering effort annually. He is also the co-inventor of a disruptive new refrigerant-free air conditioner technology that promises to substantially increase air conditioning efficiency, while providing better comfort and producing pure water as a by-product. A holder of 18 patents, he has received the Faculty Distinguished Achievement in Research Award from the Texas A&M Association of Former Students.
