Bio

Xu Liu is a scientific engineering associate in the China Energy Group at Lawrence Berkeley National Laboratory. Her recent research focuses on the electricity market, energy modeling and greenhouse gases mitigation in China. Prior to joining LBNL, Xu worked at Resources for the Future as a research assistant in Washington DC, where she assessed the design of three carbon trading pilots in China.

Xu holds a Bachelor of Arts in Economics and a Bachelor of Science in Environmental Sciences, both from Peking University, and a Master's degree in Environmental Science from Yale University.

2020 R&D 100 Award: BETTER Tool -  October 05th 2020

 

Building Efficiency Targeting Tool for Energy Retrofits (BETTER)

The buildings sector is the largest source of primary energy consumption (40%) and ranks second after the industrial sector as a global source of direct and indirect carbon dioxide emissions from fuel combustion. According to the World Economic Forum, nearly one-half of all energy consumed by buildings could be avoided with new energy-efficient systems and equipment.

The Building Efficiency Targeting Tool for Energy Retrofits (BETTER) allows municipalities, building and portfolio owners and managers, and energy service providers to quickly and easily identify the most effective cost-saving and energy-efficiency measures in their buildings. With an open-source, data-driven analytical engine, BETTER uses readily available building and monthly energy data to quantify energy, cost, and greenhouse gas reduction potential, and to recommend efficiency interventions at the building and portfolio levels to capture that potential.

It is estimated that BETTER will help reduce about 165.8 megatons of carbon dioxide equivalent (MtCO2e) globally by 2030. This is equivalent to the CO2 sequestered by growing 2.7 billion tree seedlings for 10 years.

The development team includes Berkeley Lab scientists Nan Zhou, Carolyn Szum, Han Li, Chao Ding, Xu Liu, and William Huang, along with collaborators from Johnson Controls and ICF.
