Two speakers will discuss their research and modeling of clean energy and energy demand reduction in buildings.
December’s Green Infrastructure, Climate and Cities seminar topic is Energy Technology in Buildings. Featuring Dr. Tianzhen Hong of Lawrence Berkeley National Laboratory, and Dr. Janet Reyna of the National Renewable Energy Laboratory (NREL).
Buildings in U.S. cities consume 30% to 70% of primary energy and are facing growing challenges of balancing demand and supply to optimize performance to reduce energy use, utility cost and GHG emissions. Furthermore, as cost and emissions intensities vary on the electric grid by time of day and season, the building sector could play a cooperative role in emissions reduction, system reliability improvements, and cost moderation. Both speakers will discuss their research and modeling of clean energy and energy demand reduction in buildings.
This event is FREE. The seminar is livecast to those that cannot attend in person.
Dr. Hong’s talk is titled “Pathway to 100% Clean Energy for Buildings in Cities” and will introduce urban systems research at the Building Technology and Urban Systems Division, focusing on modeling and simulation of urban buildings to explore pathways to 100% clean energy, leveraging emerging opportunities in big data, artificial intelligence, and exascale computing. Dr. Tianzhen Hong is a Staff Scientist and Deputy Head of the Building Technologies Department of Lawrence Berkeley National Laboratory. He leads the Urban Systems Group and a research team working on data analytics, modeling, simulation, and policy for design and operation of low energy buildings and sustainable urban systems. He is an IBPSA Fellow, LEED AP, and registered mechanical engineer in California. He received B.Eng. and Ph.D. from Tsinghua University, China.
Dr. Reyna’s talk is titled “The role of building energy demand in our low-carbon future: modeling opportunities with NREL’s ResStock and ComStock tools”. In this talk, Dr. Reyna will discuss on-going efforts at the National Renewable Energy Laboratory to model the residential and commercial building sectors with increased disaggregation by time, location, building type, and technology type. ResStock and ComStock, NREL’s physics-based models of the building sector, have the capability to model the residential and commercial sectors at national, regional, and city-scales. Dr. Reyna will discuss applications of the models in a major project for the City of Los Angeles modeling the potential for 100% Renewable Energy by 2045. She will also discuss the on-going project utilizing the models to develop end-use load profiles for the U.S., including regional coverage of the northeast corridor. Dr. Janet L. Reyna is a research engineer at the National Renewable Energy Laboratory (NREL) in the Buildings and Thermal Systems Center. She works on several large projects applying building energy stock modeling for national and local scenarios. Prior to joining NREL, she was an ORISE Science and Technology Policy Fellow at the U.S. Department of Energy’s Building Technologies. During her Ph.D., she received a National Science Foundation Graduate Research Fellowship to support her research on changes to building energy demand under climate change. Dr. Reyna’s research focuses on environmental impacts of urban systems, and she aims to provide information for policy decision-making with her work. She has expertise in life cycle assessment, environmental analysis, building energy modeling, vehicle emissions simulation, and spatial analysis.
