Bristol-Myers Squibb: Energy performance

Better Buildings Challenge Partners strive to decrease portfolio-wide source energy use intensity (EUI) and to increase the percent improvement compared to a set baseline. Bristol-Myers Squibb's portfolio consists of 9 plants. Bristol-Myers Squibb has improved energy performance by approximately 17% from a 2013 baseline, making progress towards a goal of 20% by 2026.

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. Bristol-Myers Squibb has achieved energy performance improvement of greater than 10% at two-thirds of its facilities. There are two facilities with less than 5% improvement in Source EUI. These facilities have been targeted for future energy efficiency improvements.

The consumption of electricity and natural gas was normalized by creating linear regression models for each facility to account for the effects of production, weather, and other factors. The corporate roll-up is performed by calculating a weighted average of the facility-level improvement rates (in percentage terms).
