TMS Real Estate & Facilities (RE&F) continually evaluates cleaner, safer and more competitive energy systems aimed at reducing energy consumption. As proof of Process Green’s success, Toyota has been recognized by the U.S. Environmental Protection Agency with its ENERGY STAR Partner of the Year Sustained Excellence Award for nine consecutive years, the most of any automaker that assembles vehicles in the U.S. Over an 11-year period at Toyota’s 14 plants, total cost saving from energy improvements has totaled more than $330 million, and energy use has been reduced by 21 percent per vehicle produced - enough energy to power 28,000 average households for an entire year.
Process Green specifically addresses lighting energy efficiency through the use of natural lighting and low-energy, high-efficiency bulbs and fixtures. Occupancy sensors and energy-efficient lights help optimize building system performance while providing an improved work environment. Furthermore, the use of energy-efficient glazing on windows reduces heat gain, thereby decreasing the amount of energy needed to keep the building cool. At Toyota Logistics Services’ Port of Portland Vehicle Distribution Center, these efficiency measures have led to a 33% reduction in energy demand.
In addition to decreasing energy consumption, RE&F also aims to improve the atmospheric quality of its facilities. As part of this effort, all new HVAC systems use zero CFC-based refrigerants to reduce ozone depletion.
As part of Process Green, RE&F installed new lighting systems at several warehouse and post-production facilities, including two Parts Centers, four Parts Distributions Centers and one Vehicle Distribution Center. Toyota’s investment at these locations totaled approximately $1.5 million and resulted in a reduction in lighting energy of more than 50%. In addition, these energy-saving technologies reduce CO2 emissions by 9.2 million pounds per year, SO2 emissions by 47,000 pounds per year and NOX emissions by 26,000 pounds per year.
At the North American Parts Center in Ontario, California, Toyota reached a Purchase Power Agreement with SunPower Corporation to install a 2.3 megawatt solar electric power system, one of the largest single-roof solar power installations in North America. The power generated from the solar PV system not only provides nearly 60% of the total electricity used at the facility, but also offers numerous environmental benefits, including the reduction of carbon dioxide emissions by 2.4 million pounds annually.
In April 2013, the Toyota Motor Manufacturing Mississippi plant in Blue Springs, MS ‘powered on’ a solar panel installation that generates enough electricity to power seven homes for one full year. The power generated by the solar array will be redirected back to the local utility, which ultimately makes it available for public use. As the fourth-largest solar project in the state, the panels further expand the energy efficiency of the Blue Springs plant, which is the most energy efficient Toyota plant in North America. Last fall, the plant obtained its ISO 14001 certification, an internationally recognized environmental designation for its environmental management systems.
