Efficient District Cooling

UT Austin - Reducing Energy Consumption Even With 20% Campus Growth - Juan Ontiveros, UT Austin; Ben Erpelding, Optimum Energy Optimum Energy Operation - Neelraj Sambasivam, Johnson Controls  UT Austin - Reducing Energy Consumption Even With 20% Campus Growth - Juan Ontiveros, UT Austin; Ben Erpelding, Optimum Energy To meet Campus growth, the University of Texas at Austin has found that it’s far more economical to be more efficient rather than invest in new power production capacity. Over the last 10 years, UT has achieved what seems impossible: reducing the chilled water system’s overall energy usage even as the campus grew by 20%.  This presentation will detail the energy efficiency and Thermal Energy Storage (TES) measures implemented and their respective results. Optimum Energy Operation - Neelraj Sambasivam, Johnson Controls When selecting the best technology for chiller operation you can choose variable speed or constant speed drives. In this presentation we will review these two options and showcase a case study from Dubai, UAE to demonstrate the outcome of utilizing variable speed drive.  Even in a high load operation like district cooling there is great benefit to this technology choice.
