CONSERVING ENERGY IN OUR FACILITIES CONT. Energy Star Challenge for Industry This continuous improvement program has recognized 69 GM plants multiple times over the past 10 years for a total of 130 recognitions. The Challenge is to reduce energy intensity by 10% within a five-year period. In 2021, five plants met the Challenge with an average 15% reduction over three years. The five plants were Qingdao Assembly, Baojun Assembly and Dongyue Engine, all in China, Silao Assembly in Mexico and Flint Assembly in the United States. Energy Star certifications provide a benchmark system for energy efficiency, identifying buildings and auto assembly plants within the top 25th percentile of operating efficiency. Energy OnStar This tool (unrelated to GM’s OnStar service), is a continuous commissioning system that monitors the performance of our HVAC equipment in real time. Approximately one-third of our operational energy use is heating and cooling, and the system allows us to quickly identify when a unit is malfunctioning and easily find opportunities for improvement. The Energy OnStar tool helped us optimally manage plant shutdowns in 2021 during the semiconductor shortage. Energy Star Treasure Hunts Through this process, we can engage nearly 100 team members to uncover quick ways to save energy. In 2021, we conducted 17 on-site and virtual energy treasure hunts, covering 61 million square feet of space, and found 175 opportunities that could potentially save the company $5 million. We also extended this approach to our suppliers during the year, including rolling out a Virtual Energy Treasure Hunt process. Learn more in Supporting Supplier Responsibility . A More Energy-Efficient Plant One of our energy efficiency projects in 2021 was at Fort Wayne Assembly, where we manufacture the Chevrolet Silverado and GMC Sierra full-size trucks. The 35-year-old plant generated steam with large natural gas boilers to heat the building and manufacturing processes. The Powerhouse also generates six megawatts of renewable electricity from landfill gas, a renewable fuel that would normally be flared, which we instead use to generate renewable electricity as part of our RE-100 target. The remainder of the plant’s electric loads are served by wind and solar and are 100% powered by renewable energy. The project will eliminate steam, an inefficient heating method, by using the waste heat from the landfill gas engines to supply most of the building heat and converting other steam loads to direct or indirect natural gas. Additional energy conservation measures include the installation of ultraviolet lamps in air handling units, lighting and dock heater controls. GM was recognized by the Michigan Battle of the Buildings in 2021 for manufacturing resiliency in the face of rapidly changing dynamics during the pandemic. In 2021, GM received recognition from Energy Star for Sustained Excellence in Energy Management for the 10th year, confirming our continuous improvement activities.
