Saint-Gobain Corporation: Energy performance

Better Buildings, Better Plant Challenge partners strive to decrease portfolio-wide source energy use intensity (EUI), from a baseline year. Saint Gobain's U.S. portfolio consists of 70 facilities as of 2019. Saint Gobain's corporate energy management program includes a focus on energy assessments, along with an on-going effort to improve monitoring and measurement of energy use through metering and submetering enhancements.

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy.  Over 15% of all Saint Gobain's facilities have exceeded 10% improvement in energy intensity since the baseline year, but some other plants have actually seen a worsening of energy intensity. These results may reflect changes in the business cycle, which can affect energy consumption. These facilities are also a good target for future efficiency efforts.

Each Saint Gobain 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 tons of material, square feet of material, and facility size in square feet. 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. 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.
