The Denville School District is about halfway through it’s $1.8 million energy improvement project. LED lights are the next step.
The Energy Savings Improvement Program (ESIP), expected to take 18 months to implement, will eventually pay for itself, school officials said.
Denville Superintendent of Schools Steven Forte said the ambitious plan to make the district’s three schools more energy efficient will continue with the installation of LED lights at Valley View’s gym and library around Nov. 25. All lights will eventually be LED, Forte said, adding energy costs will be drastically reduced by the effort.
Following an energy audit, the district accepted a 15-year plan by Honeywell with a price tag of $1.81 million for a full gamut of energy-saving devices. In return the district expects to save $2.26 million in energy costs over the same time period, according to the energy plan submitted by Honeywell.
The LED lights will be installed in all large rooms such as cafeterias and gyms and will replace fluorescent lighting. LED lights, according to Forte, are 80 percent more efficient, last longer, don’t emit ultraviolet light, are non-toxic and work well in hot or cold temperatures.
Already installed in rooms with high ceilings are destratification fans, which help recirculate trapped warm air. Temperatures can vary as much as 15 degrees in gymnasiums ceilings. The project is expected to be completed by next spring, Forte said.
