Portfolio Energy Performance

Better Buildings, Better Plants Challenge partners strive to decrease portfolio-wide source energy use intensity (EUI) from a baseline year. Nissan North America’s portfolio consists of three manufacturing plants. Their energy management activities are a part of the company's corporate social responsibility initiative, and focuses on establishing a culture of energy awareness and efficiency. Nissan uses extensive sub-metering and monitoring equipment to benchmark and identify energy improvement opportunities.

Energy Performance by Facility

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. 2012 was a year of significant transition for Nissan's manufacturing plants. The completion and start-up of a new Battery plant, a new Paint plant and new Boiler plant, combined with production launches for the the Infinity JX, Altima, Pathfinder, Nissan LEAF, the transfer of Body on Frame vehicles to the Canton vehicle plant and future model preparations presented many challenges. To achieve planned future levels of production required, additional shifts were added in 2012. As a result of these changes, in the short run, the energy performance of these plants has declined. As these transitions are completed in the fall of 2013, the full effect of the company's investment in innovative, energy efficient new plant and equipment will significantly improve its efficiency performance.

Method for Calculating Energy Performance

Each Nissan plant has its own energy intensity metric described as source energy per unit of output, with each plant producing a different product. These outputs include number of vehicles produced, number of engines, and power train components (castings and forgings) produced. The absolute change and percent change in source energy use, production output and energy intensity are tracked for each facility on both a monthly and annual basis. Nissan normalizes its plant-level numbers to account for external factors that impact energy use such as changes in production volume and heating and cooling degree days. These metrics are rolled up to the corporate level, with a corporate-wide percent improvement in energy intensity calculated by taking a weighted average of the percent change in energy intensity at the individual facilities.
