Mr. Han Li is a Scientific Engineering Associate with the Building Technology and Urban Systems Division. He joined LBNL in early 2018. Han's current research focuses on the sensor data integration, where he develops system-level key performance indicators for building energy efficiency benchmarking and diagnostics, and develops inverse modeling algorithms in EnergyPlus. He is also the lead developer of an open source building energy benchmarking and retrofit targeting tool under the CERC-BEE project. Han is a LEED accredited professional. Prior to joining LBNL, He was an Energy Analyst with ICF International.

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.
