Stephanie Siehr is a Visiting Faculty in the China Energy Group, Energy Technologies Area, of Lawrence Berkeley National Laboratory. Dr. Siehr holds an SB in Chemical Engineering from MIT, a research certificate in Chemical and Environmental Engineering from Tokyo Institute of Technology, and an MS and PhD in Environmental Engineering and Policy from Stanford University. She joins LBNL from the University of San Francisco, where she is Associate Professor of Environmental Science and Director of the Environmental Management graduate program. Dr. Siehr’s work centers on energy-based solutions to multiple environmental problems—from local air pollution to global climate change—and combines engineering with tools from political economy and organizational theory. Her research spans China, Japan, the U.S. and California, examining the design and implementation of energy and environmental policy; emissions inventories and climate action plans; international cooperation; diffusion of clean technology and management practices; and the shift from risk assessment to sustainability. At LBNL, Dr. Siehr is working on industrial energy efficiency; energy and climate policy; target allocation; low-carbon cities; and strategies for saving energy and carbon through structural change of the economy.


2017 R&D 100 Award: Benchmarking and Energy Saving Tool for Low-Carbon Cities (BEST Cities) -  November 20th 2017

The Benchmarking and Energy Saving Tool for Low-Carbon Cities (BEST Cities) provides a rapidly deployable tool to use for low-carbon planning, especially in China. This integrated, computer-based software helps local policymakers and urban planners quickly assess their city's energy use and related emissions, compare their low-carbon performance to similar cities and develop and prioritize a low-carbon development plan with strategies that reduce city CO2 and methane (CH4) emissions. BEST Cities assesses local energy use and energy-related CO2 and CH4 emissions from nine economic sectors—industry, public and commercial buildings, residential buildings, transportation, production of power and heat, street lighting, water and wastewater, solid waste, and urban green space—giving officials a comprehensive perspective on their energy and carbon inventory. The tool benchmarks 35 indicators of energy and emissions performance with other cities inside and outside of China and prioritizes sectors with the greatest energy-saving and emissions-reduction potential. Beta-testing was provided by Shandong Academy of Sciences. The technology was based on model originally developed by ESMAP known as TRACE, the Tool for the Rapid Assessment of City Energy.
