(WHAS11) - The Louisville mayor is keeping up the going green and continuing to challenge business owners to join in the energy efficient contest.
This past year 240 buildings participated in the Kilowatt Crackdown, that's 16 times higher than what organizers predicted
And the old jail building was the first city owned building to get an Energy Star label.
"It's the first of many that we hope to bring online to meet the energy star requirement...these steps will help us reduce our energy in the buildings, save us valuable resources...and most importantly save taxpayers' dollars," said Mayor Abramson.
Energy savings are still being added up but business owners say they are already seeing a difference in monthly bills.
The new Kilowatt Crackdown begins at the beginning of the year.
