    • Analysis of the Potential Energy Savings for 14 Office Buildings with VAV Systems 
      Claridge, D. E.; Liu, J.; Baltazar, J. C. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2010)
      At the beginning of an existing building commissioning (EBCx)/energy retrofit project, some form of screening is usually applied to determine whether there is sufficient potential for savings to justify a formal EBCx ...
    • Condensate Water Collection for an Institutional Building in Doha, Qatar: An Opportunity for Water Sustainability 
      Bryant, J. A.; Ahmed, T. (Energy Systems Laboratory (http://esl.tamu.edu), 2008-12)
      In almost all modern buildings today, HVAC equipment is used to provide a conditioned indoor environment while using large amounts of energy to cool, filter, and dehumidify the air in these structures. This is especially ...
    • Direct Digital Control- A Tool for Energy Management of HVAC Systems 
      Swanson, K. (Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1993-03)
      Direct digital control (DDC) applied to heating, ventilating, and air-conditioning (HVAC) systems corrects many of the deficiencies of conventional automatic temperature control systems. By applying new control sequences, ...
    • Energy Conservation Studies of Existing HVAC Systems 
      Patterson, C. L.; Phelan, T. R. (Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)
      A recent experience at ZBA in industrial energy conservation was investigating the energy savings potential of modifications to existing air handlers and to a central chilled water plant. Major system changes and new ...
    • Energy Savings with Energy-Efficient HVAC Systems in Commercial Buildings of Hong Kong 
      Yang, J.; Chan, K.; Wu, X. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 2006)
      Hong Kong has seen a dramatic increase in energy consumption in recent years, particularly electricity use in commercial buildings. The growth of electricity demand in future years is crucial both economically and ...
    • Evaluation of Energy Efficiency Measures in Hot and Humid Climates 
      Zhao, Y.; Erwine, B.; Leonard, P.; Pease, B.; Dole, A.; Lee, A. (Energy Systems Laboratory (http://esl.tamu.edu), 2010-08)
      Hot and humid climates present some of the most complex challenges for sustainable building designs. High temperatures coupled with high humidity create extreme comfort problems and exacerbate the potential for condensation, ...
    • Non-Intrusive Electric Load Monitoring in Commercial Buildings 
      Norford, L. K.; Mabey, N. (Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1992-05)
      Increased interest in optimal control, energy scorekeeping and fault detection for HVAC equipment in commercial buildings has focused attention on instrumentation required to obtain the desired data. In this paper we ...
    • Pitfalls in Building and HVAC Systems 
      Gidwani, B. N. (Energy Systems Laboratory (http://esl.tamu.edu), 1985-05)
      The purpose of an energy audit is to identify and analyze areas of energy consumption and to propose methods of conservation. In the process of completing an audit the following areas of consumption should be considered: • ...
    • Recirculation of In-Plant Air at General Motors 
      McKibben, V. L. (Energy Systems Laboratory (http://esl.tamu.edu); Texas A&M University (http://www.tamu.edu), 1983)
      The cost of doing business has been increasing at an alarming rate, especially energy-related costs. GM's yearly energy costs have surpassed the one billion dollar mark and are well on their way toward the two billion ...
    • A Thermal Sensation Index for Real-Time Tuning and Energy-Optimal Control of HVAC Systems 
      Federspiel, C. C.; Norford, L. (Energy Systems Laboratory (http://esl.eslwin.tamu.edu), 1992-05)
      In this paper we discuss and develop a thermal comfort index that addresses the limitations of applying thermal comfort indices to control applications. The derivation closely follows the derivation of PMV, but certain ...
    • Thermal Storage Options for HVAC Systems 
      Weston, R. F.; Gidwani, B. N. (Energy Systems Laboratory (http://esl.tamu.edu), 1986-06)
      With the ever-increasing cost of electricity and the high demand charges levied by utility companies, thermal storage for cooling is rapidly becoming a widely recognized method to lower cooling costs. There are three ...
