California's Lynwood Unified School District has completed an energy efficiency programme that will help the district to save up to $4.3 million in utility bills over the next 15 years.
The energy efficiency programme was implemented in partnership with Ameresco and is the second phase of the district's energy conservation initiative which was launched in August 2015.
The programme included installing LED lights, web-based energy management, wireless lighting control systems and advanced HVAC technologies in seven schools.
The phase included conducting energy retrofits at the school district's administrative office building.
A total of $3.9 million was invested, with funding coming from the California Clean Energy Jobs Act.
The energy efficiency upgrades are exceeding the estimated energy savings by an additional 9% annually. This equates to a reduction in electrical costs of 34% - representing approximately $234,000 in annual savings.
Gudiel Crosthwaite, superintendent at Lynwood Unified School District, said: "Upgrading our energy systems provides a significant financial benefit that we are able to reinvest into our critical infrastructure – an incredibly important endeavour for a public school system.
“At the same time, the environmental benefits we derive from these energy retrofits align with our emphasis on sustainability as a facet of our curriculum. We’re able to share with our students the real-world improvements we are making to reduce our own carbon footprint as a district.”
