    • Application of Innovative Technologies During Continuous Commissioning 
      Joo, I. S.; Liu, M.; Wang, J.; Hansen, K. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2003)
      This paper demonstrates the implementation of new innovative technologies during continuous commissioning practices to improve building operations and reduce energy costs. A 30-year-old typical commercial building with a ...
    • Continuous Commissioning of Public Schools 
      Joo, I. S.; Turner, W. D.; Song, L.; Dong, D.; Baltazar-Cervantes, J. C.; Napper, G.; Wei, G. (Texas A&M University (http://www.tamu.edu); Energy Systems Laboratory (http://esl.tamu.edu), 2007)
      Continuous Commissioning (CC) is a proven, highly cost-effective process that can improve building comfort and reduce energy consumption. This paper discusses the CC of three public schools in Austin, Texas. These schools ...
    • Demand-based Optimal Control to Save Energy: A Case-Study in a Medical Center 
      Joo, I. S.; Song, L.; Liu, M.; Carico, M. (Energy Systems Laboratory, 2008-12)
      Continuous Commissioning®1 (CC®) strategies include reducing simultaneous heating and cooling, scheduling the facility’s occupancy needs, utilizing free cooling, and minimizing excessive supply air and outside air. Most ...
    • Development of In-Situ Fan Curve Measurement with One Airflow Measurement 
      Liu, G.; Joo, I. S.; Song, L.; Liu, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2003)
      Fan airflow is the key parameter for air volume tracking control in variable air volume systems. One of the airflow measurement methods is to determine airflow using the fan speed, fan head, and fan curve. Both fan speed ...
    • Optimal Control in Three-deck Multi-Zone Air-Handling Units: A Case-Study 
      Joo, I. S.; Song, L.; Liu, M.; Douglas, B. (Energy Systems Laboratory, 2008-12)
      A multi-zone air-handling unit was popular several decades ago due to the convenience of small sized modular units, which were inexpensive to install and easily maintained in a mechanical room. The cost and convenience ...
    • Performance Analysis of Dual-Fan, Dual-Duct Constant Volume Air-Handling Units 
      Joo, I. S.; Liu, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2001)
      Dual-fan, dual-duct air-handling units introduce outside air directly into the cooling duct and use two variable speed devices to independently maintain the static pressure of the hot and the cold air ducts. Analytical ...
    • Real-Time Forcast Model Analysis of Daily Average Building Load for a Thermal Storage System Control 
      Song, L.; Joo, I. S.; Guwana, S. (Energy Systems Laboratory (http://esl.tamu.edu), 2009-11)
      Thermal storage systems were originally designed to shift the on-peak cooling production to off-peak cooling production to reduce the on-peak demand. Based on the current electricity charging structure, the reduction of ...
