Enough to pay for a huge LED retrofit, at least.
Using a financing system similar to the “soft loan” “Warner homes, greener homes” program being launched in the UK to fund energy efficient home upgrades, New England Energy Management is upgrading 50,000 fixtures at Ford’s Detroit Campus. Ford pays nothing upfront, and will instead pay for the retrofit with the energy savings over five years.
And there’s another wrinkle. While LEDs are pretty energy efficient to start with, the units will be paired with automatic dimming systems to maximize the savings. Cool!
