Howell, Michigan
130,000 square feet
2024 Michigan Battle of the Buildings winner with a 12.96% reduction in weather-normalized source Energy Use Intensity (kBtu/ft²).
General Motors was awarded in the 2024 Michigan Battle of the Buildings competition, in the Warehouse/Distribution/Service category for a 12.96% reduction in weather-normalized source Energy Use Intensity (kBtu/ft²).
In 2024, General Motors (GM) took decisive steps to improve the performance and sustainability of its Share Spare Warehouse in Howell, Michigan, completing a series of building envelope upgrades, inventory optimizations, and infrastructure decommissions. The result was a more efficient, better-sealed, and environmentally aligned facility.
While the initiative originated from a pest control need, the project ultimately delivered broad energy and operational benefits, from lower infiltration to better indoor comfort and reduced equipment load.
General Motors has long been a leader in automotive innovation, and its commitment to sustainability is just as strong. Guided by their Zero Crashes, Zero Emissions, Zero Congestion vision, GM consistently integrates environmental stewardship into both operations and facilities management.
The Share Spare Warehouse project is a continuation of this legacy. The Howell site has seen several prior sustainability efforts, including the replacement of high-intensity discharge (HID) sodium lighting with LED fixtures, resulting in 50% electricity savings. In 2024, GM partnered again with Ideal Setech, as well as Ideal Contracting and Ehrlich Pest Removal, to focus on energy conservation through physical improvements to the building’s infrastructure and operations.
As part of the 2024 project, the 130,000 sq. ft. warehouse underwent several major repairs: sealing structural gaps to reduce air infiltration, foam was applied to a corner seam stretching from floor to ceiling, and metal flashing was added to exterior corners and over holes in the insulation to further tighten the building’s envelope. In addition, a large-scale material scraping resulted in the removal of 590,000 pounds of obsolete steel machinery parts. This not only decluttered the facility but also reduced the volume of material requiring heating during colder months. To cut back on energy usage, one of four existing air conditioning units was decommissioned. Operational efficiency was also improved by minimizing the time that overhead dock doors remained open during deliveries, helping to limit unnecessary air exchange and temperature loss.
These improvements had a notable operational impact: improved temperature stability inside the warehouse and lower overall energy usage. This facility saw a 12.96% reduction in weather-normalized source EUI from 2023 to 2024. This is equivalent to a 15% reduction in GHG emissions.
This project illustrates how small operational and infrastructure enhancements can deliver big results, especially when viewed through the lens of continuous improvement. At GM, sustainability is more than a corporate initiative; it’s a shared responsibility integrated across its global operations.
Being recognized by the Michigan Battle of the Buildings further validates these efforts. With a large footprint across the state, GM sees these wins not just as achievements but as benchmarks in its journey to a cleaner, more efficient future.
“Our favorite part of this project was identifying and implementing continuous improvement solutions that reduce energy costs and improve our operational performance,” said a General Motors Representative.
Looking ahead, GM will continue conducting seasonal environmental audits and tours to identify further opportunities for energy and water efficiency across facilities.
The Michigan Battle of the Buildings is an awards and recognition program for energy use reduction open to all Michigan area commercial, industrial & multi-family buildings. The program is a way to encourage energy-efficient practices in buildings across the state and to instill a spirit of friendly competition among the area’s building owners and operators. There is no cost to enter the competition.
The 2024 Michigan Battle of the Buildings competitors saved $8.8 million in energy costs and avoided 44,098 metric tons of CO2e, which is equivalent to the carbon sequestered by 44,233 acres of US forests in one year! This year, we had 13 industry-specific category winners.
