Municipal Energy Savings Project - Summary

In 2007, the City initiated a multi-year, multi-million dollar energy efficiency and renewable energy project for municipal facilities. This endeavor was a significant step toward modernizing municipal facilities and achieving long term energy and cost savings.

In 2009, the City hired Honeywell International as its Energy Services Company (ESCO), to conduct energy audit of municipal facilities (60% of which were Worcester Public School buildings).

Following the energy audit, energy conservation measures were selected based on cost, expected return on investment, and need for improvements at each facility. A baseline was also established from which the anticipated energy cost savings over 20 years could be measured. Identified critical investments to aging infrastructure included improved heating and cooling systems, heating systems' conversions from oil to natural gas, insulation, air sealing, water conservation, upgraded lighting fixtures, and energy management control systems.

In 2011, the City signed an Energy Savings Performance Contract (ESPC) with Honeywell International, Inc. to install the agreed upon energy conservation and renewable energy measures (ECMs) across 92 of the City’s largest facilities (of the 171 total). This action stemmed, in part, from the 2007 Climate Action Plan’s key recommendation to do such a project for municipal buildings.

As of September 2015, most of the Energy Conservation Measures in the original contract (2011) have been completed. However, a number of additional energy conservation measures have been added to the original scope of work via three subsequent amendments. This work is on-going with an anticipated completion date of 2017.

ESPC and Sustainability Goals

Since its commencement, this project has been central to the City’s commitment to meet a number of its sustainability goals, including:

  • Qualifying for a Green Community Designation
  • Leveraging resources available through the DOER Green Communities Program to reduce energy demands throughout the community, and foster the growth of the green economy;
  • Reducing the City’s energy usage and associated costs;
  • Improving the condition and energy efficiency of aging school and City facilities;
  • Reducing the City’s greenhouse gas emissions and its reliance on fossil fuels; and
  • Leading by example and demonstrating to the community at large what can be done to save energy and to improve sustainability of its operations.
