PORTFOLIO ENERGY PERFORMANCE

Better Buildings, Better Plants Challenge partners strive to decrease portfolio-wide source energy use intensity (EUI) from a baseline year. In 2014, 3M succeeded in meeting its original 25% energy intensity improvement target based on a 2005 baseline.  3M repledged to an additional 30% energy intensity improvement setting 2015 as the new baseline. 3M's portfolio consists of 93 facilities as of 2019. 3M's corporate energy management program includes energy champions and energy teams at all major facilities, worldwide. Since 2005, these teams have implemented just nearly 5,000 energy projects, thanks in part to a capital set-aside program dedicated to energy efficiency projects. 3M designs new equipment and facilities to be energy efficient.

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. Several of 3M's facilities are off to a good start posting significant improvements during the first reporting year, conversely, plant expansions and modifications have increased the energy intensity at a few plants. These facilities are also a good target for future efficiency efforts.

METHOD FOR CALCULATING ENERGY PERFORMANCE

The scope of 3M’s pledge includes a total of 93 different plants, each manufacturing a complex mix of products. As a result, energy consumption is modeled and evaluated at several levels.  Source energy use, production output, and weather conditions are tracked for each facility on both a monthly and annual basis.  3M normalizes its energy use to account for the impacts of production volume and several weather-related variables.  Interactions among these variables are also considered.  Total corporate improvement in energy use is calculated by taking a weighted average of the improvements in energy intensity for each facility.
