    • Impacts of Static Pressure Set Level on the HVAC Energy Consumption and Indoor Conditions 
      Liu, M.; Zhu, Y.; Claridge, D. E.; White, E. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1996)
      Air static pressure must be maintained at a certain level leaving the air-handing unit (AHU) to force a suitable amount of air through the terminal boxes. However, an excessive static pressure level is often used due to ( ...
    • Integrated Commissioning for a Large Medical Facility 
      Zhu, Y.; Batten, T.; Turner, W. D.; Claridge, D. E.; Giebler, T.; Liu, M.; Zhou, J.; Cameron, C.; Keeble, B.; Hirchak, R. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2000)
      The energy costs of heating, ventilating and air conditioning usually represents a large portion of the utility bills for a medical facility. One large, modem medical center located in the hot and humid region of southern ...
    • A Novel Procedure to Determine Optimal Air Static Pressure Set-points and Reset Schedules in VAV Air Handling Units 
      Zhu, Y.; Liu, M.; Claridge, D. E.; Turner, W. D.; Powell, T. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1998)
      Air static pressure set-point or schedule for VAV AHLJ systems is one of the most crucial operational parameters for satisfy lug the building load, maintaining the room comfort level and saving energy costs. This paper ...
    • Optimization Control Strategies for HVAC Terminal Boxes 
      Zhu, Y.; Batten, T.; Noboa, H.; Claridge, D. E.; Turner, W. D.; Liu, M.; Zhou, J.; Cameron, C.; Keeble, D.; Hirchak, R. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2000)
      The HVAC terminal boxes are one of the major building HVAC components. They directly impact the building room comfort conditions and the energy costs. How to operate the box in a highly energy efficient way and maintain ...
    • A Simple and Quick Chilled Water Loop Balancing for Variable Flow System 
      Zhu, Y.; Batten, T.; Turner, W. D.; Claridge, D. E.; Liu, M. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2000)
      For many modem buildings, the chilled water loops and risers are equipped with variable speed pumping systems. How to quickly balance the loop or riser to satisfy the cooling requirement and reduce energy consumption is a ...
    • Terminal Box Airflow Reset: An Effective Operation and Control Strategy for Comfort Improvement and Energy Conservation 
      Liu, M.; Abbas, M.; Zhu, Y.; Claridge, D. E. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2002)
      A new terminal box operation and control strategy, airflow reset, is developed to improve building comfort and energy efficiency during unoccupied and lightly occupied hours. The airflow reset lowers the minimum airflow ...
    • Use of EMCS Recorded Data to Identify Potential Savings Due to Improved HVAC Operations & Maintenance (O&M) 
      Liu, M.; Zhu, Y.; Claridge, D. E. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1996)
      In most chiller and boiler central plants, the energy management and control systems (EMCS) monitor and record key operation parameters and energy production continuously. A method was developed to identify potential O&M ...
