ESPC Step C - Project Implementation


Work Phase I - Comprehensive Energy Efficiency and Building Modernization Program & Two Solar Projects:

 

Project Managers. Honeywell International's Project Manager and the Division of Energy and Asset Management (namely - Division Director and Chief Clerk of the Works), the City’s designated project manager for the Municipal Energy Savings Project, are in regular and frequent contact throughout implementation phases to discuss the status and resolve any issues that come up as the work progresses. 


Sub-Vendors. More than a dozen sub-vendors, many of them local companies (including WF Lynch, Ostrow Electric, Grodsky & Co., and Coghlin Electric), employing hundreds of union employees, worked on this project.

Work Phase I took place over 5 years (2011-2015) across 92 City-owned buildings. Most of the work was completed by 2014 and included such ECMs as insulation, weather sealing, heating/cooling system upgrades (conversion from oil to natural gas where possible, installation of more energy efficient equipment, etc.), and installation of a computer power management system.

Additionally, two solar projects at Worcester Technical High School (256 kW DC) and Sullivan Middle School (186 kW DC) were completed in 2014.

Tying-in the building systems of 50 municipal facilities to a sophisticated control system with real-time electricity usage, was completed in September 2015.

Some specific examples include installing new boilers at 6 schools, completing building envelope projects (insulation and air sealing) at 7 schools, and upgrading and installing energy management control systems at 36 "high-energy" use schools. The City Hall boiler has been converted from oil to natural gas and replaced, and a new chiller installed to serve the building and the Oval (i.e. the ice rink on the common).

Anticipated completion date for all work in this phase (which includes the City's acceptance of the work as completed) is early 2016. 

                                      

Work Phases II, III, IV - Solar Projects and Lighting Retrofits

Between 2013 and 2014, the original scope of work was amended three times to expand the work from primarily building energy efficiency ECMs to lighting efficiency and renewable energy projects. Work implementation is taking place as follows:

  • Work Phase II - fall 2016
  • Work Phase III - 2016 (solar)
  • Work Phase IV - end of 2017 (solar at the Greenwood Landfill and lighting retrofits)

Solar Energy Installations (Work Phases II-IV)

9 New Solar Projects:

  • Solar installations at 8 public schools and associated white roof coating application to 4 school roofs, extending roofs' lifespan by 20 years (guaranteed), and
  • Solar installation at the former Greenwood Street Landfill (8.1 MW-DC)

Installation of the Parking Canopy Solar PV System - Sullivan Middle School, Worcester, MA - winter 2015-2016

Municipal Lights' Retrofits to LED (Work Phase IV) 

  • Lighting Retrofit Project for all ~14,000 City-owned streetlights to LEDs
  • Lighting Retrofit Project at four municipal parking garages to LEDs
