The US Environmental Protection Agency (EPA) has recognized eight Toyota manufacturing sites in North America for achieving a 10% reduction in energy intensity through its ENERGY STAR Challenge For Industry program. Collectively, these eight sites have reduced energy intensity by nearly 24% from baseline. Energy intensity is measured relative to efficiency improvements in process and equipment.
The ENERGY STAR Challenge For Industry program is only awarded to individual industrial sites. To gain recognition, the site’s company must be an ENERGY STAR partner. Earlier this year, Toyota Motor Engineering & Manufacturing North America, Inc. (TEMA) received its eighth consecutive ENERGY STAR Sustained Excellence Award for its continued leadership in protecting the environment through energy efficiency and management.
The eight Toyota facilities recognized by the EPA include: Bodine Aluminum (Jackson, Tenn., and St. Louis, Mo.); Toyota Motor Manufacturing, Alabama (Huntsville); Toyota Motor Manufacturing Canada (Cambridge and Woodstock, Ont.); Toyota Motor Manufacturing, Indiana (Princeton); Toyota Motor Manufacturing, Texas (San Antonio); and Toyota Motor Manufacturing, West Virginia (Buffalo).
|Examples of reduction in energy intensity|
|Plant example||Description||Reduction from baseline|
(Bodine Aluminum, Jackson, TN)
|Replacement of lighting in several plant areas with energy-efficient fluorescent lights with sensors.||13.8%|
|Innovative lighting technology
(Toyota Motor Mfg., AL)
|Installation of Ultra Constant Discharge lighting in the plant’s parking lot.||24.1%|
|Hot water boiler linkage
(Toyota Motor Mfg. Canada)
|Installation of new controls allowing proper mixture without numerous adjustments.||28.5%|
(Toyota Motor Mfg., IN)
|Elimination of using outside air to cool/heat paint booth; current air intake is taken directly from plant, making temperature consistent.||36%|
Since 2006, Toyota’s US manufacturing operations have received 18 Energy Star Plant Awards from the US EPA, recognizing each plant’s energy performance over the past year and scoring in the top 25% of its industry.
