The Dublin City School District has saved nearly $500,000 in energy costs since instituting conservation strategies and installing equipment.
District Business Affairs Director Annette Morud gave board members a rundown on energy savings over the summer during an Oct. 8 meeting.
"We're very excited about the numbers we got," she said.
Through new energy saving policies instituted this summer, the district was able to save $89,000 in energy costs in June and July.
The district had custodians and maintenance workers put in four, 10-hour days in June and July to keep the schools closed one day a week and closed all buildings at 6 p.m., Morud said.
Zone cooling was also utilized to cool only parts of school buildings that were occupied.
"We increased the temperature set points to 74 degrees for occupied and 85 degrees unoccupied," Morud said.
If buildings were rented, air-conditioning costs were figured into rental costs, which brought in $40,000 Morud said.
"We're pretty happy with what we saw," she said of the new summer programs.
The district also installed some energy conserving equipment across the district in 2011 and has seen savings on energy bills from that.
Through House Bill 264, the district was able to take out $5.7 million in no-interest loans to install energy-efficient boilers, water heaters, lighting and solar power equipment in school buildings across the district.
The district has seen a difference of $497,096 on its gas and electric bills between the 2010-11 and 2011-12 school year.
Morud said some of that different could have come from the mild winter in 2011-12, but energy conservation across the district has saved some green as well.
"We're very proud of that and very happy with those savings," she said.
