Minutes by FD, MN


Green Communities Funds


Total GC grant of $148,000: $110,723 is the RISE quote for retro commissioning of Mid. Sch. & HS (Gerry will re-send that detail). We applied in May; in September, Kelly Brown at DOER asked various q’s; including how we’re going to deal with the rebate program, and what will be identified during retro-commissioning. Within a week, RISE responded; re the latter: excess ventilation, set-points, scheduling. Now we’re waiting for DOER again.


In the meantime, Kelly asked on 10/31: what else do we propose to do with the grant funds?


GM: since we’ve gotten clarification that an audit is not necessary to replace the Blake water heater,  looked at Table 4, and suggested the outdoor lighting work at Blake and Memorial School parking lots, respectively $18,287 and $16,620; totaling $34,907. RISE provided details on 10/31 for those measures, they match the values in Table 4. FD offered to scrutinize the specs; offhand recommended that the latest thinking in LEDs is to utilize dimming/controls as much as possible; this may include dimming down or turning off in a parking lot, and tuning to desired light levels.


This would leave $2300. The full $148,000 must be spent down before applying for next round.

  1. as to when the deadline might be for next round of funds.

Solar on Roof at DPW

Solar roof loading analysis for DPW defined as parts A, B, and C: we now have a stamped engineering report from Solect’s engineer, EAH Structural Consulting dated 11/29/17, saying “existing roof framing systems are judged to be adequate to withstand the loadings imposed by the installation of the solar panels.” Cost for this was in range of $1000. (HMTB should have done this.)


Solar on DPW: original design by Solar Design Associates needs to be re-done; originally it was design-bid-build, a performance specification. There were only two bidders, one didn’t meet DCAM Cert., other was very high, above the budgeted amount. Now we would ask SDA to do firm specs, and ask for base bid and design alternates to cover parts of the roof, to help ensure that we meet the budgeted amount (allotted from DPW budget _____________).



[At this point, Marie Nolan took over from Fred Davis recording the meeting’s minutes as Fred now began a discussion regarding the LED STREET LIGHTS project.]



11.2.17 continuation of notes ….


Light Smart Energy Consulting (George Woodbury) has offered to meet with MEC, present its report, and walk through the next steps.  FD cannot be at a fixture selection meeting so we may need Woodbury’s help for that.


MEC questions posed:

  • How do we reconcile the numbers between the DPRS assessment (utility report) and Woodbury’s field count?
  • Does it affect the $1 price?  No.  George is checking with Eversource on the agreement.
  • Does it change the figures we are going to get? Woodbury will take the counts and recommend substitution.  Ask Light Smart to recommend approach to deciding what wattage to choose if there is a street with several wattages (e.g. lowest or average?)


Bottom line – not much change in terms of energy, 11 fewer but higher wattages shown on DPRS (347 on DPRS and 333 in field).  Correct when on S2 rate (town rate), but we are on S1 (Eversource rate).

$20,000 is the maintenance.


Questions for Woodbury:

  • Provide an estimate for maintenance contract.
  • Where are other streetlights needed in Town such as at the Pfaff Center, Public Safety building, DPW?
  • Are you going to provide a GIS map of where the lights are?
  • What is the timeline for taking possession of the streetlights?
  • Are old documents still valid?
  • How do we tell Eversource that the count is incorrect?
  • How do we negotiate a change in our bill?   (Need to go to Selectmen when we want to enter into a contract.)
  • How do you choose light color?  Why did Wellesley choose 2,700?
  • How do you correct for glare?  (Often biggest complaint)


First step is to set up Woodbury attending MEC meeting. We do not want to own the lights and maintain them before the retrofit. Needs to happen together.


Are we doing test lights to decide on color?? Six years ago – 5,000 was norm. Since then, always been 4,000. The past year, some lights are available at 3,000 kelvins and they are still efficient as the higher ones.  Wellesley is choosing 2,700 kelvins (they found efficiency drops between 3,000 to 2,700)


We may end up with 4 wattages and 2 types.

Must keep good records and rules of thumb for dial settings at certain locations.


Personal preference – Westwood has lights that are 4,000 kelvins.  Newburyport has 3,000.


LED – colors will be better under lamps.


Lighting has to be SMART control ready.  Do not add it now as expensive .  Woodbury would not recommend controls now because of our size.

DRAFT September 28, 2017 Medfield Energy Committee Meeting minutes

Attendees: Fred Davis, Jerry McCarty, Marie Nolan, Lee Alinsky and Cynthia Greene

  1. Meeting minutes from June 7 were reviewed.  Fred requested a change to the recusal information.  It was noted that since the minutes there is new information about the Blake Middle school hot water heater.  Minutes were accepted and Lee will determine who should receive them at Town Hall so that they are posted on the Medfield Town Website and he will post them on the MEC google docs.
  2. Update on Blake – DOER said that Blake Middle School domestic hot water heater ASHRAE audit for $7,875 is not needed.
  3. We discussed who was officially on the Committee and what constituted a quorum. Lee will check in with Town Hall to determine.
  4. Google documents – Lee could not manipulate the documents. Marie will look at how to give Lee administrative rights.
  5. LED street lights. Fred Davis emphasized that he has recused himself from a specific bid on the LED street lights for Medfield, but he is allowed to help advise us on the process, but not the purchase.

Jerry gave us an email from Light Smart with the status on the project

  • The field audit has been completed
  • Looking at preliminary design
  • Expect a document with the preliminary design in a week.
  • At the next meeting the committee has to approve whether to go with MAPC and receive a 30% incentive from DOER (for Medfield that is $22,400) or to go through an independent process. Light Smart indicated that if we went independently it would be faster as MAPC is doing bundling of town requests.

Fred Davis explained that the process at the MAPC is evolving, that DOER thinks that bundling is better.  The faster we do the work the more time for savings.   The estimated annual savings for the Medfield project is $32,600.  Unless we were significantly delayed (10months or more) it is more cost effective to go with MAPC, although we do not know how much transactional costs there will be with MAPC vs going independently with Light Smart.

The Town must decide on the types of lights and fixtures.   There are two kinds of lights being sold now.   In the past the lights were 5,000 Calvin that emitted a blueish light.   The options now are for 3,000 Calvin, a warmer, yellower light or 4,000 Calvin a neutral, but blueish light.   Medfield could do a pilot as was done in Cambridge and Northampton, to see which light color the community members like.  The way to do this would be for committee members to observe and then let the community know and take opinions.   Northampton did this, but the results were not conclusive.  We also discussed that Westwood and Cambridge have smart controls on their lights, but that is more upfront costs.   Westwood and Cambridge have 4,000 Calvin lights.   Both lights are the same price.

Fact sheet



  1. Green Communities.  Jerry handed out an email received on 9/26/17 with questions from DOER on our May submittal.   Jerry and Axum Teferra, from MAPC, will be discussing the comments.  Jerry will then take the questions to RISE Engineering.  We do not know how long RISE will take to answer and then for DOER to approve the answers and the project.  Jerry will discuss with Axum the timeframe on spending these funds.   The funds have to be spent before the town can apply for further Green Communities grants.  The cost of the retro commissioning for the energy management systems is $117,000 for both schools.   The grant is for $138,000.  Jerry has a $70K request in the Capitol budget  for new software to replace the 1996 version that is currently running in the schools.
  2. DPW roof. Jerry has a contract with Solect engineers to look at the roof and to see if it is structurally adequate for PV.  The engineer’s site visit is next week.  Once Jerry has their report he will give it to the Building inspector to see if the roof is viable for a solar installation or it first would need modifications.
  3. Public safety building. The PV system is up and running.  The dashboard is being worked on.  We will try to meet at the public safety building so we can see the dashboard.

Future Work for the committee.   Lee outlined some of his ideas and others added ideas and all were discussed.

  1. Microgrids for the town buildings.   Cynthia explained that microgrids cannot cross public ways in MA, but that the hospital development might be a good location for a microgrid.  There are state incentives for microgrids.  We all want to be better educated on microgrids.


MA microgrids

  1. Use of the landfill site for PV array.  Lee would like us to get MA DEP’s current advice on this as Solar Design has already given us specifications for an array at this location.  If a study is needed to determine the adequacy of the landfill closure for PV, we could investigate if we could use the Green Communities funds to do the study.
  2. Solar canopies at the Middle and High School parking lots with EV charging stations. The town could potentially take advantage of the EV charging station incentives.  Fred suggested that we invite the energy managers from Westwood and Wayland to speak with us as they have done a lot of work in energy improvements, Wayland doing them all at once including PV at their town hall parking lot.  We discussed other places with parking lot PV canopies – REI, Walden Pond, and Logan Airport.

Walden Pond




  1. Net Zero planning. Fred Davis would like us to consider this at a future meeting.   There is a MAPC Oct 11 meeting on getting to net zero and a 45 minute MAPC webinar.  Concord passed a net zero article at their Town Meeting.



Meeting adjourned 9:15 pm.

Next meeting – Tuesday Oct 17 at 7:30 pm (hopefully at the Public Safety Building.)

Lee Alinsky new Chair of MEC

This emailed memo came today from the now former chair of the Medfield Energy Committee, Fred Bunger, who is moving to Wellesley to be nearer to family.  Medfield benefited hugely from Fred’s excellent, thoughtful, and persistent stewardship of the MEC.  Fred engineered the town becoming a Green Community last year, with all that entails, including the receipt of a $148,000 DOER grant and the development of a plan to reduce the town’s future energy consumption by 20% – a reduction which is over an above the 30% reduction that the MEC had already helped the town achieve under the original MEC Chair, Marie Zack Nolan.  That grant money is now being used to undertake a recommissioning of the HVAC controls at the Medfield High School and the Blake Middle School, the town’s two biggest energy users, so as to make both operate more efficiently.

Energy Committee


TO:  Select Board, Town Administrator and Facilities Director

DATE: July 12, 2017

SUBJECT:  New Energy Committee Chair

Dear Sirs,

This letter is to confirm that the Medfield Energy Committee has chosen Lee Alinsky as Chairman, by vote of the members in attendance at the June 8, 2017 Energy Committee meeting.


I will be moving from Medfield in September 2017, so can no longer serve on the Energy Committee.


Please make Lee welcome and give him the excellent support you have given me for the past two years.  Your ongoing support of the Energy Committee will continue to help the Town achieve its efficiency goals.


Thank you for the honor of serving you.



Fred Bunger

This from the Medfield Energy Committee chair, Fred Bunger –

LED streetlight

Letter to Editor


I am writing in support of Article #25 on the Town Meeting warrant.  Article #25 proposes that the Town save $31,870/yr. on lighting cost by converting 347 streetlights in Medfield to LED.   Medfield would join over 50 other Massachusetts towns that have made the conversion to LED.


The net cost of the project is $67,600 after State grants and utility incentives.  This gives a simple payback of 2.1 years or 47% return on investment. With conservative allocation for future replacement and doubled maintenance costs, the payback is still an excellent 3.1 years.


The LED lights will provide a more natural light than the HID lights currently used.  LED lighting improvements in the last few years have permitted adjustments to the light color to avoid the harsh blue light seen in earlier LED installations.  To see what the Medfield lights might look like, take a drive on Route 109 into Westwood, which converted to LED recently.


The Medfield Energy Committee has been considering LED street lighting for several years.  The recent availability of State grants makes this an excellent time to implement the project.  We urge your support.



Fred Bunger, Chairman Medfield Energy Committee



Green Community recognition 4/12

The Medfield Energy Committee was tenacious, working hard over many years to position Medfield to become a Green Community, by satisfying the five required criteria, most recently by crafting a five year plan for a further 20% reduction by the town government’s energy use – that was filed and accepted by DOER over the winter.  The DOER invitation to the Green Community designation event appears below.  The five year plan was a “further” reduction, because the Medfield Energy Committee already had affected over a 30% energy use reduction since MEC first started its work.

It turns out that saving the planet also helps to save the town money.

And, don’t forget that qualifying as a Green Community also gets the town a $148,000 DOER grant, as well as access to future ongoing competitive DOER grants. So doing the right thing also earns the town money.

Westwood used one of the DOER competitive grants ($250,000) to buy and convert all its streetlights to LED fixtures.

Our own streetlight purchase ($1) and LED conversion (in round numbers, about $100,000) is a warrant article at our upcoming town meeting.  In general terms the town would spend about $100,000 to buy and convert to LED’s, get a now available, time limited $30,000 DOER grant to do so, and save about $30,000/year in future reduced electricity charges, for a pay back of the cost to convert in less than three years.

Draft minutes

Medfield Energy Committee

Jan 12, 2017


Fred Bunger presiding, Jerry McCarty, Cynthia Greene, Lee Alinsky, Fred Davis, Paul Fechtelklotter (taking minutes)


  1. December 8 meeting minutes accepted. Fred B. will make effort to put all 2016 meeting minutes in a single location for easier access.


  1. Annual report – FB.

Made minor updates to the draft report. Still awaiting updates for the solar projects – Fred B will submit revised report once he receives them.


  • Green Communities –FB:


Fred B spoke with Kelly on Medfield’s application status. He received very positive feedback but no official response.

Axxum confirmed that there is money available for her to assist with our application for initial grants after Medfield receives confirmation of achieving Green Community status.

The expected deadline for submitting the grant application is 3 March. Jerry will be “on point” for the grant submittal with MEC support.

The MEC will have to identify priorities for spending the ~$148K in grant money, using Table 2 of the Energy Reduction plan as the starting point. Retro-commissioning of the High School and Blake are likely to be high on the prioritized list of projects since it will likely be difficult to secure funding for those projects in a competitive grant scenario.

Jerry has received preliminary pricing for retro-commissioning and EMS software upgrades from vendors and should have more data points by our February meeting.  The costs were highlighted at the December MEC meeting and total ~$80K. He is also just starting to develop a list of items to include in his capital submission to the town.

Jerry is getting bids for replacing halogen lights at the library, weatherizing windows at the library, and replacing an exterior door at the library. Fred D. volunteered to assist with the library lighting effort.

Fred B. will make sure that committee members have the final version of Table 4 that was included in our Green Communities application package.


  1. LED streetlights – FD:

Fred D. walked through his analysis of typical maintenance/support contract terms that Medfield should put in place if the town owned the lights.

New funding sources and grants have recently become available that will reduce the net cost of the replacement effort from ~$89K to ~$67K

There are limited funds available so it is important to move forward quickly.

Fred B. will send Fred D’s package and data to Jerry and Mike Sullivan. He will also write a letter to the Board of Selectman on behalf of the MEC to start the process.

Should the project go forward, Medfield will still have to choose an LED technology. We can either leverage MAPC to make a recommendation or do it ourselves.  A suggestion was made to engage Westwood for advice since they recently went through a similar effort.


  • Town Solar – JM:


DPW Solar: No change in status since the last MEC meeting. Still engaged with Solect (who is the SRECs aggregator, solar maintenance, and reporting), who advised town to wait until next round of solar programs.


Public Safety Solar: everything is set but still waiting for ACA approval, which should come before 19 January.


  1. Solarize Medfield Status:

Tabled until February meeting.


  1. Other business.

Tabled discussion on best way to archive committee materials until February meeting.


Meeting adjourned around 9:15.

Beaton Secretary Judith F. Judson Commissioner February 1, 2017 Congratulations on the Town of Medfield's designation as a Green Community! This designation is quite an achievement and reflects the hard work and tireless efforts your community has exhibited in meeting the Green Communities Designation and Grant Program's five criteria. Meeting these criteria is proof of Medfield's position as an energy leader in Massachusetts, poised to reduce its energy costs, improve the local environment and implement energy efficiency and renewable energy projects with funding through the Green Communities Designation and Grant Program. The purpose of this letter is to confirm your Green Community designation in writing and provide you with program information and activities relevant to you as a newly-designated Green Community. Along with this designation, the Town of Medfield has been awarded a grant of $146,815. A formulaic allocation has been established that consists of a base grant per community of $125,000, plus an amount adjusted for population and income, with an additional $10,000 for designated communities that met Criterion 1 through adoption of as-of-right siting for renewable energy generation. To receive this grant award, the Town of Medfield will be required to submit a project application proposing how these funds will be spent. The Green Communities Division ("Division") will begin accepting grant applications immediately on 9 am, February 13, 2017. The Green Communities grant application guidance with submission instructions is provided as a separate attached document. Please be sure to work with your Regional Coordinator, Kelly Brown at 508-767-2703, to identify potential energy projects and coordinate with vendors and utility companies. SIGNS Each designated Green Community receives four ( 4) 12" x 18" aluminum signs to be displayed in your community. While you are free to place these signs wherever you choose within your community, the Division recommends installing them in highly-visible, high pedestrian traffic areas (such as near municipal offices, schools, and downtown business districts, and/or within parks and along walking paths). If installed on roadways, the Division recommends hanging them at approximately eye-level for motorists, to maximize readability. DESIGNATED 20UI CERTIFICATES Each Green Community will receives an official certificate for display pronouncing the municipality's designation as a Green Community and including the designation date and signatures of the Governor, Lieutenant Governor, Secretary of Energy and Environmental Affairs, and Commissioner of the Department of Energy Resources. FACES OF GREEN COMMUNITIES WEB PAGE Finally, the Commonwealth is extremely proud of and inspired by the efforts of the 185 Green Communities. From the tip of Cape Cod to the Berkshires, Green Communities such as yours are pursuing their own unique pathways to a clean, sustainable, and more economical energy future. To showcase the diversity of the Green Communities and their individual efforts and results, we have created a Faces of Green Communities web page. Within three months of your designation as a Green Community, we ask that you complete the attached questionnaire and return it to us, along with a photo of your local energy team posing with one of your mounted Green Community signs. Please send your materials to Jane Pfister at Once we receive your information and photo, we will quickly add your story to the web site. Again, congratulations on becoming a Green Community. The Division looks forward to working with the Town of Medfield to meet the objectives of the Green Communities Designation and Grant Program and to support you in meeting your local energy goals. Thank you for your commitment to a cleaner energy future for Massachusetts.
