    • Building Aautomation system embedded air-handling unit performance degradation detector 
      Song, L.; Wang, G. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2014)
    • 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 ...
    • Feasibility Study of Developing a Virtual Chilled Water Flow Meter at Air Handling Unit Level 
      Song, L.; Swamy, A.; Shim, G. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2011)
      In this paper, a virtual Air handling unit (AHU) level water flow meter is explored by using a control valve as a measurement device. The flow through the valve is indirectly calculated using differential pressure over ...
    • Heat Balance Analysis to Validate the Heat Dissipation Rate of a Man-Made Lake as a Heat Rejection 
      Song, L.; Hayes, T.; Dawson, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2011)
      Power plants were originally designed to use convenient bodies of water and cooling towers due to unavailability of these sources. Though the Environment Protection Agency (EPA) has been pushing regulation that requires ...
    • An Integrated Air Handling Unit System for Large Commercial Buildings 
      Song, L.; Liu, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2001)
      This paper presents an integrated air handling unit system (OAHU) for large commercial buildings. The system introduces outside air into the interior section and circulates the return air to the exterior section. Detailed ...
    • The Office Air Handling Unit versus the Two Dedicated Air Handling Unit System 
      Song, L.; Liu, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2002)
      Both analytical and the numerical methods have been developed to compares the energy performance of the OAHU systems and the two-AHU (TAHU) system. The OAHU system saves up to 1.85 kilojoules heating energy for each kilogram ...
    • 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 ...
    • Optimizing HVAC Control to Improve Building Comfort and Energy Performance 
      Song, L.; Joo, I.; Dong, D.; Liu, M.; Wang, J.; Hansen, K.; Quiroz, L.; Swiatek, A. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2003)
      This paper demonstrates the benefits of optimal control in well-designed and operated buildings using a case study. The case study building was built in 2001. The HVAC and control systems have been installed with ...
    • 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 ...
