Walter J. Sullivan Water Purification Facility
The Walter J. Sullivan Water Purification Facility is the single largest energy user of any individual municipal facility. In FY12, the Water Department completed an intensive energy efficiency audit of the Sullivan Facility. Click here to learn more about the energy use and efficiency programs at the City's water purification plant.

School Facilities
School facilities account for half of the City's total building area and one third of the total energy use. Click here to learn more about the energy use and efficiency projects taking place throughout the Cambridge Public School District.

Renewable Energy
Cambridge has installed a total of over 72 kilowatts (kW) of solar photovoltaic (PV) rooftop arrays on five municipal facilities including:
1. Cambridge Rindge & Latin High School (31.36kW)
2. City Hall Annex (26.5kW)
3. Frazier Administration Building (2kW)
4. Frisoli Youth Center (3.26kW)
5. Russell Youth Center (9.26kW)
Planned FY14- Walter J. Sullivan Water Purification Facility (in design for solar PV)
Planned FY16- King School (design plan includes solar PV to support net zero energy/carbon neutral design)

LEED Rated Facilities
Since 2004, the City has operated under the policy that all new construction or major renovations should be designed to be certifiable under the US Green Building Council's LEED rating system. The City of Cambridge currently owns and operates 74 facilities, of which six are LEED certified, and three will be seeking LEED certification.
1. City Hall Annex (LEED-Gold, 2004)
2. Russelll Field, Field House (LEED-NC, 2006)
3. Robert W. Healy Public Safety Facility (LEED-Silver, 2009)
4. Russell Youth Center (LEED-Silver, 2010)
5. Cambridge Main Library (LEED-Silver, 2010)6.
6. War Memorial Recreation Center (LEED-Silver, 2010)
7. Cambridge Rindge and Latin High School (in application for LEED-Silver certification)
Planned FY14-5 Western Avenue (in application for LEED-Silver certification)
Planned FY16- King School (Net zero energy or carbon neutral design)

Fuel-Efficient Fleet
Since 2006, all requested new vehicles must go through a Green Fleet Policy review to address fuel economy and emissions. To date, one third of the City's administrative and light service vehicles are either hybrid (31 vehicles) or plug-in electric (2 vehicles).

City Streetlights
In FY13, the City began to design for the conversion of all citywide street lights to LED technology. The $6 million project is expected to be completed in three years and save an estimated 3,931 MMBtu annually, avoiding $360,000 in energy costs and the emission of 555 tons of CO2e annually.
