Mingsheng Liu, Ph.D., P.E. – Omaha, Nebraska
Founder, CEO and CTO of Bes-Tech and BESTChina

Bes-Tech’s Founder and C.E.O., Mingsheng Liu, Ph.D., P.E., brings his expertise and cutting-edge research from his many years in academia to the industry. Dr. Liu developed the Total Performance Oriented Retrofit (TPOR®) service and related technologies in partnership with a group of researchers at the University of Nebraska and engineers at the Omaha Public Power District (OPPD). He originated the patented and patent-pending energy saving devices that have come to define Bes-Tech as a leader in building energy systems technologies.

The following are a few of his most notable accomplishments over his long career:

Assisted in the founding of the CC® (Continuous Commissioning®) line of technologies*.  CC® is known to optimize  HVAC and building control systems to reduce building energy consumption by an average of 23%.  Application guidelines for these technologies have been developed for the Federal Energy Management Program.

Assisted in the founding of the CCLEP (Continuous Commissioning® Leading Energy Project) technologies. CCLEP is meant for use in the private industrial sector and by public utility companies. The technology integrates optimal control with operation functions during the retrofit phase. Compared with traditional energy system retrofit methods, CCLEP increases overall energy savings by 30% and reduces capital costs by 20%.

*Neither Dr. Liu nor Bes-Tech are currently licensees of the CC® or Continuous Commissioning® trademarks.  Said trademarks are currently the property of the Texas A&M Engineering Experiment Station.
