NIEHS replaced35aging ultralow temperature freezers with new ENERGY STAR-certified ULT freezers，resulting in annual reduction in electricity usage of 232896kilowatt-hours（kWh）。That is a64%annual reduction in greenhouse gas emissions，or the equivalent of 150 metric tons of carbon dioxide。

电气Stewardship—Kimberly Jones，Richard Weaver，April Byrd，Kelly Powell。

Each year，NIEHS generates more than2000 surplus items，including electronics，office furniture，and scientific equipment。The NIEHS Direct Donation Program donates many of these to educational institutions and nonprofits。In its first year，program donations valued at more than$250000 were diverted from landfills and directed to local universities and high schools。

能源和流动管理—Bill Blair，Benjamin Hocutt，Lee Howell，Marcos Flores。

Replacement of the underground high temperature hot water piping insulted in a50%reduction in thermal loss by the Central Utility Plant，reducing annual natural gas usage by300000 therms and decreasing CO2 emissions by1587 metric tons。

Good Neighbor—Paul Johnson，Timothy Adkins，Craig Upson，David Mohammadi，Roger Weidner，Thomas Carol，Crispin Hernandez，Bill Steinmetz，Carranza Smith，Antares Nicklow。

Green Labs—NIEHS recognized。

Fifteen environmentally controlled lab rooms were replaced with2100 square feet of more energy efficient space。The new rooms are projected to save520000kWh per year of electricity，the equivalent of 368metric tons of greenhouse gases。

水使用效率和管理—Kyle Askins，James Victor Stancil III，Bill Blair，Terry Wells，Daniel Burk，Heather Davis，Joseph Shealey。

Anew variable-volume pumping system，along with new valves，pumps，motors，and other design changes，will increase energy efficiency in the preheat and reheat hot water system of Modules A-E in Building 101。The annual estimated energy savings is540000kWh per year。

Wellness—NIEHS recognized。

The institute’s COVID-19 Testing Operations Project gave employees confidence in their safety and well-being on-campus during the pandemic and was critical to planning for a return of the full workforce。NIEHS experienced a very low rate of known cases among its employees and no known on-campus transmissions。

“This year，NIEHS staff received an incredible number of Green Champion Awards，”said NIEHS DirectorRick Woychik，Ph.D.“I am honored to work with individuals who are so deeply committed to making our institute a leader insustainability efforts”

NIH Green Labs Program

The NIH Green Labs Program，now in its third year，grants sustainability certifications to NIH laboratories based on a self-assessment survey。Despite the pandemic，NIH in 2020received52applications，the highest number of applications yet。Six received gold certification，33silver，nine bronze，and4labs did not meet the criteria for certification。
