EXPERIENCE

Since April 2020, Dr. Yuan has been working on EnergyPlus software development, engineering research, and EnergyPlus user support at GARD Analytics. He has contributed to various new feature development, bug fixes, refactoring, and code review activities for EnergyPlus official releases (v9.4-v9.6). He is also one of the major contributors on ASHRAE Standard 140 Weather Drivers project for energy modeling software validations and ASHRAE Standard 229 for ASHRAE 90.1 Appendix G based ruleset development.

Dr. Yuan’s research interest includes new building envelope materials, cooling technology applications, building performance evaluation, natural ventilation, and indoor environment modeling. He was a Co-PI for two externally funded research projects at the University of Idaho. He has also taught energy efficiency courses to the senior and graduate students at University of Idaho and Boise State University. In addition, Dr. Yuan also has 8+ years of experience in engineering consulting for sustainable designs, energy efficiency programs, and building simulations, using popular simulation programs such as EnergyPlus, TRNSYS, Radiance, Ecotect, and ANSYS Fluent (Computational Fluid Dynamics).

Dr. Yuan’s research and development experience has also extended beyond the field of green buildings. He has experience in the research and development of an electromagnetic wave based scientific instrument hardware and software at Oliden Technology in Texas. There he led the inversion subsystem development for a million-dollar Directional Electromagnetic Resistivity downhole tool, and was responsible for related mechanical designs, electronic system design/analysis, and software/firmware algorithm development in the project. He also conducted large scale numerical simulation (FEM, FVM) for electromagnetic wave transport phenomena and mechanical and material strengths as well as experimental validations, to ensure that the tool can achieve super high precision specifications when working under the high-temperature high-pressure drilling environment.
