About the LBT

The Laboratory Benchmarking Tool (LBT) is the successor to the Labs21 Benchmarking Tool, which was retired in 2019 after 16 years of service. The LBT provides expanded access to the historical Labs21 dataset via a modern graphing interface, along with many new and reconfigured data fields designed to meet the needs of today's lab community. Additional modules will be added to the LBT to further expand its functionality in the coming years.

The LBT is sponsored by the Federal Energy Management Program at the U.S. Department of Energy (DOE). It was developed by kW Engineering, Lawrence Berkeley National Laboratory, and the International Institute for Sustainable Laboratories (I2SL). The Actionable Insights module was sponsored by Siemens Smart Infrastructure and was developed by I2SL and kW Engineering. The Portfolio Manager Connection, Operational Practices module, and metric units mode were sponsored by FEMP and were developed by LBNL and kW Engineering.
