PORTFOLIO ENERGY PERFORMANCE

Better Buildings, Better Plants Challenge partners strive to decrease portfolio-wide source energy use intensity (EUI), and to increase the percent improvement compared to a set baseline. As of 2016, Legrand North America's portfolio consists of 21 facilities, including 13 manufacturing and distribution facilities, and 8 commercial office buildings. Legrand's corporate energy management program focuses on technology, process and behavioral changes. While a key component of the program is installing submeters at all facilities within the organization, Legrand has also undertaken a variety of projects ranging from lighting retrofits, machinery upgrades, process improvements and behavioral changes to achieve its energy results. These combined efforts resulted in Legrand well exceeding its annual goal of 2.5% improvement in 2016 and achieving ~17% cumulative improvement in just four years from its 2012 baseline year.

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.  Legrand has achieved an energy performance improvement of 10% or more at over 70% of its facilities, and 50% of its facilities have achieved over 15% improvement over the past four years. Three of Legrand's 21 facilities have experienced no improvement or an increase in energy intensity, indicating the company still has room to improve on its already significant energy efficiency accomplishments.

METHOD FOR CALCULATING ENERGY PERFORMANCE

Legrand has a mixture of facility types, including plastic molding, metal fabrication, assembly operations, and warehousing, in addition to office buildings. Each of the facilities has an energy intensity metric (source energy per unit of output) most suitable for its type of operation. These outputs include pounds of material, feet of material, direct labor hours, and facility size in square feet. The absolute change and percent change in source energy use, production output (where applicable), 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.
