Primary Topic: Energy Efficiency
This case study from the U.S. DOE details the approach Nissan Motor Co. has taken to certify all three of its U.S. plants to Superior Energy Performance under the department's Better Buildings initiative, saving close to 1,600 billion Btu of primary energy and $9.4 million in energy costs annually.
Nissan's enterprise-wide approach to implementing the ISO 50001 EnMS and SEP saved Nissan about $19,000 per site compared to what it expects it would have spent had it adopted a site-by-site approach, and required as little as 0.4 annual full-time equivalent in internal labor. Nissan credits its success to streamlining implementation by using a "Central Office" and a "sampling" approach to the ISO 50001 audits. Additional benefits were achieved by leveraging EnMS procedures used at the Smyrna site and sharing common processes from the company’s existing ISO 14001 Environmental Management System.
