10. General Motors GM Opens First-Ever LEED-Gold Certified Automobile Manufacturing Facility Lansing, Mich. -- General Motors’ new Lansing Delta Township Assembly Plant has received a gold certification from the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) program. The building is the only automotive manufacturing plant in the world – as well as the largest facility and the most complex manufacturing site -- to ever receive any level of LEED certification. Over the first ten years of operations, the facility is expected to save over 40 million gallons of water and 30 million kwh of electricity. LEED Certification

17. Joint All COS Staff MeetingGeneral Motors Capital ESPI –Similar to ESPI, except that major components of these projects are capital –Similar in implementation process-PRM –Carried in project forecast and WFG project targets whereas ESPI projects are not as they are funded from budget

18. Joint All COS Staff MeetingGeneral Motors CESPI-Bedford Melt Project –Melt initiative focused on improving melting process inside the fence. –A capital project funded by WFG replaced five existing furnaces with one modern, flexible, energy efficient furnace and total savings are being tracked at $5.3 million per year level. –Since start of the furnace in April 2007, energy savings are at $2.6 million per year. –Project also achieved a $1.8 million per year savings in productive materials as the furnace can use waste aluminum chips as input material.
