The USDOE Forrestal Building Lighting Retrofit: Preliminary Analysis of Electricity Savings
MetadataShow full item record
In September of 1993 a 36,832 fixture lighting retrofit was completed at the United States Department of Energy Forrestal complex in Washington, D.C. This retrofit represents DOE's largest project to date that utilizes a Shared Energy Savings (SES) agreement as authorized under Public Law 99-272. As DOE's first major SES contract, it was important that every aspect of this project serve as the cornerstone of DOE's Federal Relighting Initiative, including the careful measurement of the electricity and thermal energy savings.
DescriptionThe Department of Energy estimated that the lighting retrofit would reduce annual electricity use by 6.146 million kWh (62% of the lighting electricity use), and lower peak electric demand by 1,300 kW. Estimates of the electricity savings were $399,058 per year, or $1,350,386 over a seven year period. Environmental impacts of this project have been estimated in the range of 3,791 to 4,160 tons/yr (3.4 to 3.8 million kg) of carbon dioxide (CO2) avoidance, 31.7 to 33.2 tons/yr (28.7 to 30.1 thousand kg) of sulfur dioxide (SO2) avoidance, and 13.6 to 16.0 tons/yr (12.3 to 7.3 thousand kg) of nitrous oxide (NO2) avoidance.
