Watertown Sustainability | Green Community Projects
Watertown is a Green Community

Watertown will soon celebrate its 6th anniversary as a Green Community.  Becoming a Green Community has allowed the Town to be eligible for state grants for energy efficiency and renewable energy projects.  These projects are part of an effort by the Town to lead by example in being sustainable and will save the community money. To date, Watertown has worked on an array of energy activities from upgrades for reducing energy use in municipal and school buildings to adopting energy efficiency measures in the building code for new public and private projects. Since the base year of 2010 Watertown has reduced its weather normalized Municipal energy usage, and the resulting Green House Gas emissions, by over 18%.

Police Station Photovoltaics
       Watertown's Police Station has a photovoltaic array and a state of the art geothermal heating and cooling system.

Municipal Sustainability Projects  

Street Light LED Retrofit (Phase 2) - The Department of Energy Resources awarded Watertown a $207,505 Green Community Competitive Grant to replace all remaining energy inefficient streetlights with highly efficient LED’s that will provide equivalent lighting while consuming 62% less energy. The $300,000 project will be fully funded by the DOER award along with an incentive from Eversource.

The Town will save over $57,000 per year in electricity and maintenance over the 20+ year life of the LED lights.  The lighting retrofit will reduce Watertown’s CO2e Green House Gas emissions by 234 metric tons per year.  For the press release follow the link:

Municipal Energy Efficiency Retrofit - The Town is implementing an energy efficiency retrofit program covering 14 Municipal and School facilities.  The Town Council presentation provides details on the $7+ million project funded through an Energy Savings Performance Contract.  By law the Performance Contract must be funded by the savings accrued from the efficiency improvements, and the energy savings are guaranteed by the contracting company. Bottom line, at no net cost to tax payers Watertown was able to upgrade and improve mechanical systems, lighting and building envelopes, all which will save a significant amount of energy and reduce greenhouse gas emissions. Over the life of the Performance Contract the Town is expected to save over $1.8 million in energy, maintenance and operational costs.

Street Light LED Retrofit – In 2012 Watertown was awarded a $192,000 Green Communities grant which, along with NSTAR incentives and additional investment by the Town, allowed the retrofit of 1269 street lights to highly efficient LED’s. Energy cost savings from these new LED lights are $29,800 per year along with a reduction in Green House Gas emissions of 140 metric tons of CO2e annually. 

Police Station Building - The new Police Station has a community meeting space, a solar array, and a highly efficient geothermal heat pump.  Between the electricity generated and the SREC’s sold approximately $15,000 in annual savings are attributed to the Police Station solar array. Also, the police station is adjacent to a community park that was redeveloped on the former Browne School site. 

Public Works Building Solar Array - In 2010 a federal grant entirely funded the installation of a 54 kW solar array at the DPW building.  Annually, this system saves approximately $14,000 in energy costs and reduces Watertown’s Green House Gas emissions. 

High School Solar Array - Watertown High School installed a 6 kW solar array which is used for educational purposes and saves about $1,000 per year in energy costs. 

Design Guidelines and Standards – Watertown has created Design Guidelines and Standards for commercial and mixed use projects.  The design standards apply to development and redevelopment and strongly encourage a sustainable design where environmental responsibility is an integral part of the design.  This includes state of the art building systems and envelope, LEED certifiability, renewable energy sources, and landscape strategies to promote garden spaces and healthy tree growth.

Sustainability Activities in the Community

In addition to the Municipal efforts sustainability activity has significantly increased in Watertown’s residential and business community.

Solarize Massachusetts|Watertown - Multiple Watertown residents participated in the Solarize Mass program. Solarize Mass is a partnership between MassCEC and the Green Communities Division of the Massachusetts Department of Energy Resources (DOER), and has led to more than 2,700 residents and business owners in 51 cities and towns across the Commonwealth signing contracts for small-scale solar electricity systems.

Arsenal on the Charles Sustainability - The reuse of the former Arsenal site has provided many cultural, economic and environmental benefits.  One example of sustainability accomplished in the reuse was the installation of a solar photovoltaic array on the 311 Arsenal St Building which was the largest rooftop installation in the state when it was completed.

Mt. Auburn Cemetery - Recent development included a LEED certified Horticultural Center and Greenhouse utilizing geothermal and solar PV technology to save energy and rainwater collection to save water. 

Perkins School for the Blind – Recent projects includes a LEED certified Lower School with a green roof and a 34 kW solar array.

Sustainability Resources in the Community

Neighborhood Solar - is a program sponsored by a Watertown resident to facilitate households installing reduced cost solar photovoltaic (PV) systems. Neighborhood Solar brings together the communities of Watertown, Arlington and Cambridge, along with a local PV installer, to provide discounted volume pricing on high quality solar PV installations.  After many successful PV installations in earlier iterations of Neighborhood Solar a new program has just been launched.

Mass Save Energy Audits
- Watertown homeowners, landlords, and renters can get utility sponsored no cost energy assessments from Mass Save.  These assessments start with an online questionnaire and usually result in a no cost and no obligation home energy assessment.  Typical assessments include free energy saving light bulbs, shower heads, faucet aerators and a report of recommended Energy Conservation Measures (ECM’s) such as additional insulation.  A report will be issued that will detail the cost (including any available utility incentives or rebates) the amount of energy saved per year and the payback of each proposed ECM. The homeowner is under no obligation to get any of the recommendations done.  Click on the following link to sign up for a free assessment to start saving energy, money and reduce your carbon footprint.

Rebates and Incentives - Mass Save also offers many utility sponsored rebates and incentives for energy saving measures, these cover everything from highly efficient appliances to deep energy retrofits to getting rid of an old refrigerator, click the following link for more information:
