Dr. Song: As significant advancements in smart sensor and information technology become possible, there is an emerging need for the digitalization of building energy systems to achieve energy efficient, disaster resilient and autonomous building operations. Therefore, the digitalization of building energy systems has been the research focus for the Building Energy Efficiency Laboratory (BEEL) at the University of Oklahoma in the past ten years. In this talk, I plan first to give an overview of the research activities carried out in the BEEL. Then, I will introduce a data-analytics framework design in detail. The framework is constructed in a way to connect the data on comfort, occupancy, weather, energy use, time-of-use (TOU) electricity pricing, the specific systems in the buildings, and code compliance benchmarks together to generate meaningful information for advanced building energy system diagnosis and optimal control.
Dr. Shabgard: The oil and gas industry is a consumer of fresh water and often competes for resources that are also in demand by local communities for agricultural and municipal purposes. Significant amounts of water are produced in the oil and gas extraction activities, the disposal of which is often a challenge. High levels of solutes in the oil and gas produced water poses a challenge to membrane-based and evaporative desalination technologies. Freeze-desalination processes are naturally well-suited for such low-quality feed streams since pure ice crystals can be produced even in highly concentrated brine. However, the existing freeze-desalination technologies suffer from numerous issues preventing their wide-spread use. This talk describes a novel zero-liquid discharge (ZLD) eutectic-freeze method developed by our group at OU for purification of water produced from various industrial processes, including oil and gas extraction. The proposed system resolves the issues common to current freeze-desalination systems, while offering superior heat transfer performance ascribed to direct-contact between the coolant and the brine.
Dr. Song is Lloyd G. and Joyce Presidential Professor in the Aerospace and Mechanical Engineering at OU. Song’s research is focused on virtual sensing and optimal building energy system design and operation. She has served as a principle investigator for close to $4 million research projects. She is also an active ASHRAE member and a founder and was an active faculty advisor of the OU student ASHRAE branch. She served as a sub-committee chair of ASHRAE TC 75 Smart Buildings for two years and has served as the current TC75 research committee chair and an alternate for ASHRAE handbook committee since July 2017.
Dr. Shabgard is an Assistant Professor at the School of Aerospace and Mechanical Engineering at OU. He obtained his PhD in Mechanical Engineering in 2014 from the University of Connecticut. Shabgard’s research includes multiphase heat transfer and flow, CFD, heat pipes, thermal energy storage, and desalination. He has been involved in multiple projects sponsored by federal agencies as well as industrial partners.
