City and Public Schools of Waterbury, CT

Waterbury, CT

Project Overview

The energy performance contract was initiated as part of a comprehensive energy solutions program to allow the City to implement energy conservation measures; capitalize on clean energy programs/initiatives; leverage federal, state, and Connecticut Energy Efficiency Fund grant and capital financing opportunities; and evaluate renewable energy sources and green energy technologies.

This EPC project was one of the largest ever performed in the State of Connecticut. It consisted of badly needed upgrades across both the school district and City facilities; including, most notably, the replacement of 31 boilers that were past their useful life. Another significant measure addressed was a comprehensive upgrade of energy management systems to Direct Digital Control (DDC).


The highlight was a 31 boiler installation and mobilization plan within a SINGLE summer window including extensive asbestos abatement work, steam trap repairs, pumps and condensate tanks, and complete removal of the old boilers.

Completing this work prior to the end of 2017 had a benefit of additional energy rebates from Eversource. The $3M+ rebate granted was partially awarded because of the significant amount of boiler upgrades performed. Another advantage was the annual energy thermal reduction they will benefit from by their first winter season, an estimated 157,000+ CCF, reduced by the new steam and hot water boilers.

Five Examples of the 20+ Energy Conservation Measures:
  • Backup Power Generation
  • Boiler Upgrades
  • Chiller Replacement
  • Interior Comprehensive & Exterior
  • LED Lighting
  • Solar Photovoltaics
