PORTFOLIO ENERGY PERFORMANCE

Better Buildings, Better Plants Challenge partners strive to decrease portfolio-wide primary source energy use intensity (EUI) and to increase the percent improvement compared to a set baseline. Owen Corning met its first Better Plants goal — a 25% reduction in primary energy consumption at U.S. facilities — ahead of schedule and set a new goal of 12% more in savings by 2025. The company's portfolio consists of 62 facilities as of 2020. Owen Corning's energy management program emphasizes low-cost/no-cost and capital upgrades focused on energy efficiency, process improvement, and Total Productive Maintenance. With an energy intensity improvement of 15% since its baseline year of 2018, Owens Corning has achieved its 12% reduction in energy intensity target five years early. Owen Corning has shared its energy efficiency practices with its global industrial partners and is planning to do the same through DOE's Better Plants Challenge Program.

ENERGY PERFORMANCE BY PROPERTY

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy. 31 of Owens Corning's 62 plants have experienced energy intensity reductions since 2018. Eleven of these facilities have improved energy performance by greater than 10% since 2018. Owens Corning's energy efficiency efforts include upgrading to LED lighting, installing chilled water controls, and monitoring and optimizing compressed air systems, to name a few. The company also restructured production at one facility, leading to a 37% reduction in that facility's energy intensity.

METHOD FOR CALCULATING ENERGY PERFORMANCE

Owen Corning produces different products and, therefore, uses different metrics to calculate plant-level energy intensity. Depending on the plant, Owens Corning calculates energy intensity in terms of source energy consumed (in MWh’s) divided by production (in metric tons, squares, board-feet, etc.). The percent change in energy intensity is tracked for each facility on both a monthly and annual basis. The energy consumption of each plant is rolled up to the corporate level for total MWh’s consumed. The denominator used for calculating energy intensity at the corporate level for this Better Buildings, Better Plants Challenge goal is total production in metric tons.
