Central Islip Union Free School District – Phase II

Central Islip, NY

Project Overview

Energia completed a successful Energy Performance Contract with the Central Islip School District in 2013. This Phase I project implemented various upgrades including high efficiency fluorescent lighting, boiler upgrades, temperature control upgrades, and Solar PV at one building. The energy-savings was estimated to generate more $700,000/year, however during the measurement and verification phase, Energia determined that the actual savings exceeded this goal by approximately 9.5%.

Due to the success of the Phase I project, the Central Islip School District engaged Energia again in 2019 to initiate a Phase II Energy Performance Contract. This project focused on improving the classroom environment by upgrading to state-of-the-art LED lighting technology, replacing over 30,000 SQFT of ceilings, and eliminating pneumatic temperature controls, district wide.


The critical goal for this project was improvements to the learning environment.

By upgrading the aging fluorescent lighting, the District will enjoy the guaranteed energy savings from this upgrade, but also aesthetic improvements in the classrooms with the new LED technology and demolition/replacement of old ceiling tiles. This project will also focus in on elimination of overheating in the classrooms. This chronic issue for many school buildings in the Northeast is due to failed pneumatic temperature controls. In this project, the pneumatic system will be replaced with a Direct Digital Control (DDC) system, so that facility operators can tightly control heating setpoint and comfort levels throughout the heating season.

Five Examples of Energy Conservation Measures:
  • Comprehensive LED Lighting Upgrades
  • Ceiling Replacements
  • Elimination of Pneumatic Controls
  • Solar PV
  • Cogeneration

“I don’t have to worry about [Energy Performance Contracts] because I am working with pros. It’s the idea that you can trust what they do.  They know what they do and protect YOUR interests when they are working with outside folks who come in and work on the project.  It’s not always the case in our business, that you will have that level of trust and comfort.”
