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. Owens Corning met its first Better Plants goal (25% reduction in energy consumption at U.S. facilities) in 2017, three years ahead of schedule. They then set a new target of an additional 12% savings by 2025 from a 2018 baseline. Owens Corning quickly achieved this goal in 2020 and set a third goal to reduce their energy intensity 28% by 2030 from the same 2018 baseline. Owen Corning's portfolio consists of 59 facilities as of 2021. Owen Corning's energy management program emphasizes low-cost/no-cost and capital upgrades focused on energy efficiency, process improvement, and Total Productive Maintenance. To date, Owens Corning has achieved an energy intensity improvement of nearly 17% since its baseline. Owens 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. Forty-four of Owens Corning's 62 plants have experienced energy intensity reductions since 2018. Fifteen of these facilities have improved energy performance by >10% over the same timeframe. Owens Corning's energy efficiency efforts include upgrading to LED lighting, installing chilled water controls, and monitoring and optimizing compressed air systems. 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. 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, however, is total MM $ revenue.
