The Lockport School District saved $231,000 in energy costs during the first year of an energy performance monitoring program, officials said Monday evening.
This was nearly twice the expected savings.
The Board of Education heard a report from Sempra Energy Solutions, which contracted to do energy audits of all 13 buildings after the replacement and upgrading of various lighting and heating facilities.
"Your project is working better and smoother than most school districts'," said David Abery, a Sempra performance monitor who reviewed last year's utility bills.
The company reported that the district saved $255,989 in energy costs during the first year. After deducting Sempra's $25,000 annual fee, the district had a net savings of $230,989.
Sempra had guaranteed the district a first-year energy savings of $129,600.
Abery said the savings followed such cost-cutting measures as:
Replacing or insulating roofs.
Replacing old boilers in the high school.
Installing energy management controls and monitoring them by computer.
Converting dish-washing machines from electric to gas.
Replacing steam traps in North Park Middle School.
Retrofitting the lighting in all 13 buildings.
The work included the replacement of 4,875 light fixtures, 12,250 lamps, 5,830 ballasts and 875 reflectors. The district also replaced all its "Exit" signs, which are always lighted.
Formerly known as CES/Way, the company first did an energy audit for $79,898 three years ago. It was since purchased by Sempra after the merger of Southern California Gas and San Diego Gas & Electric.
