Oak Ridge Reservation
• Annual energy savings of 768,061 million Btu
• Water use reduction of about 170 million gal per year
• Carbon sequestration equivalent to 1,325,744 tree seedlings grown in an urban environment for
10 years or 11,751 acres of pine forests
• Emission reductions equivalent to the reduction of 9,470 passenger vehicles; 120,242 barrels of oil;
the energy used by 4,563 homes annually; or 270 coal rail cars
Table 5.2 demonstrates that the ESPC goals meet or exceed TEAM goals. The status of the energy
conservation measures (ECMs) is outlined in Table 5.3.

Electric Metering
The EPACT requires federal agencies to install advanced electric metering, where practical, to
improve the operating efficiencies of federal buildings. Measuring and managing energy use at the
building level provide baseline data for assessing the effectiveness of energy savings programs and
promote energy use awareness among building managers and occupants.
UT-Battelle has had a policy of metering for electricity at the building or substation level for many
years. There are currently about 350 standard electric meters installed at ORNL (Table 5.4). Almost all
buildings that use electricity have at least a standard meter. While the site has approximately
450 structures identified as buildings, many of them are warehouses and equipment sheds that use little, if
any, electricity. Of this total, approximately 120 buildings represent 70% of the space and 80% of the
electricity use. Based on the criteria established in Guidance for Electric Metering in Federal Buildings
(DOE 2006), 38 buildings at ORNL, which use over $32,000 in electricity each year, require advanced
metering. When complete, buildings that account for 65% of UT-Battelle’s total electrical consumption
will have advanced metering and all buildings will have at least a standard meter.
