opportunities to incorporate them into our fleet and realize emissions reductions. Our U.S. Medical- Surgical business, which owns and operates the largest fleet within our enterprise, recently placed its first order of EVs — marking the beginning of integrating these vehicles into our overall strategy. We continue to explore additional opportunities to increase the electrification of our fleet and drive down fuel consumption. Reducing our electricity use In our distribution centers, pharmacies and offices, we focus on reducing energy use and finding alternative sources of energy. Our most significant use of energy is electricity in our buildings, whether they are offices, distribution centers or warehouses. Across our locations, we work to use less energy for lighting and heating, ventilation and air conditioning (HVAC). In fiscal year 2018 (FY18), McKesson made a commitment to design new office buildings in accordance with a newly developed connected buildings standard. We’re also making an ongoing effort to apply this standard retroactively to as many existing assets as practical. This technology will give our teams elevated visibility to building operations, as well as a real-time analytics platform to identify and diagnose inefficiencies in HVAC, lighting and other building systems. We anticipate these findings will result in energy savings and extended equipment lifetimes. In FY21, we transitioned locations in Jacksonville, Fla.; Scottsdale, Ariz.; and Irving, Texas, into the program, and began similar work in Columbus, Ohio, and Mississauga, Ontario. We implement lighting retrofit projects to convert less efficient lighting fixtures to LEDs, which use far less electricity. Since FY20, in the U.S., we have realized an estimated average reduction of 23% in our electricity use at participating buildings due to these LED installations across 30 locations covering more than 6.3 million square feet. This equates to a reduction of 19.9 million kilowatt hours (kWh) of electricity. In FY21, we expanded the program to 450,000 additional square feet across two distribution centers. Leadership in Energy and Environmental Design (LEED) As part of McKesson’s energy reduction strategy, we pursue Leadership in Energy and Environmental Design certification (LEED), when feasible, for newly constructed or renovated U.S. offices. We have earned LEED for Commercial Interiors Gold certification for Building 3 in Scottsdale, Ariz., in October 2020, and earned LEED for Commercial Interiors Silver certification for offices in Jacksonville, Fla. Jacksonville is also undergoing WELL Building certification . These two LEED certified offices join our portfolio of already-certified buildings, which includes offices in Irving, Texas; Richmond, Va.; San Francisco, Calif.; The Woodlands, Texas; the other two office buildings in Scottsdale, Ariz.; and our distribution center in Aurora, Ill. Since FY20, in the U.S., we have realized an estimated average reduction of 23% in our electricity use at participating buildings due to these LED installations across 30 locations covering more than 6.3 million square feet .
