Johnson Controls: Energy performance

Better Buildings, Better Plants Challenge partners strive to decrease portfolio-wide source energy use intensity (EUI) from a baseline year. Johnson Controls' U.S. portfolio consists of 31 facilities, encompassing approximately 7.6 million square feet of floor space, as of 2021. They achieved their challenge goal of 25% energy intensity reduction in 2016, which is in addition to a 25% EUI reduction achieved between 2002 and 2008. In 2020, they established a new goal of 25% energy intensity reduction by 2029. Johnson Controls conducts Energy Hunt assessments that have uncovered hundreds of energy efficiency opportunities and millions of dollars in savings.

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. Nearly two-thirds of Johnson Controls' manufacturing facilities have reduced energy intensity from 2018 to 2021. Over the next couple of years, the company prioritizes deep efficiency retrofits at its facilities with the greatest energy use. 

Johnson Controls manufactures a variety of building technologies, including HVAC and refrigeration equipment, security, life safety, and building management systems. Johnson Controls calculates energy intensity at the facility level, using source energy divided by site output. For many sites, the output used is revenue, but other measures are used for a few sites. To obtain corporate-level performance improvement, a weighted average of site performance is developed using baseline facility energy use as the weighting criteria. To ensure that energy consumption and intensity are internally consistent over time, Johnson Controls adjusts its baseline to account for mergers, acquisitions, divestiture, and other structural changes. From 2018 to 2019, Johnson Controls divested eight additional facilities in 2020. Historical data shown to the right have not been adjusted to account for divested sites, but the energy performance data above incorporates base year adjustments to account for 2021 progress.
