Overview
Personal Profile
Sugirdhalakshmi (Sugi) Ramaraj joined the Residential Buildings Research Group at NREL in 2020. Her research focuses on building energy modeling and simulation, advanced control and optimization, distributed energy systems, cold-climate heat pumps, and experimental testing and performance analysis of heating, ventilating, and air conditioning systems.
Prior to joining NREL, Sugi completed her master's and Ph.D. at Purdue University. For her Ph.D. thesis, she developed a hybrid network flow algorithm for optimal control of large-scale distributed energy systems. Her master's thesis was on the development of high-performance, cost-effective, cold-climate vapor compression heat pumps using flooded compression with regeneration and cooled compression with economizing technologies. She has two years of industrial experience in design and manufacturing at Schlumberger.
