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 a modern graphing
interface, along with many new and reconfigured data fields designed to meet the needs of today's lab community.
Additional modules are frequently added to the LBT to further expand its functionality.
Development of the Energy Score module was supported by I2SL's Labs2Zero
program. I2SL's Labs2Zero Founding Sponsors are listed below.

v1.50, 7 October 2022
LBT Internationalization: part 2 of 2. For additional details please refer to the FAQ.
Added worldwide address capabilities with google address lookup, and backfilled existing addresses to comply
with new format.
Added currency selector, with exchange rates taken from currencyfreaks.com on 1 Sept 2022. All existing entries
were treated as US$.
Updated US GHG emissions to use 2020 state-by-state values from eGrid (via carbonfootprint.com) and added
international GHG factors using 2020 data from ourworldindata.org. District hot water GHG emissions use Energy
Star 2022 standard. District chilled water emissions use Energy Star 2022 standard, but scaled by electricity
GHG factor for building's location. GHG emissions intensities of existing buildings will have changed as a
result of this update.
Source energy is now only calculated for US buildings, using Energy Star 2018 national averages.
Site EUI is now the default view for charts.
Added filters for region and country.
Updated climate zone calculator to include non-US locations and to use latest version of ASHRAE Standard
169-2021. Note that climate zones of some existing buidlings may have changed as a result of using more recent
