MEDFIELD ENERGY COMMITTEE
Lee Alinsky, Cynthia Greene, Paul Fechtelkotter, Fred Davis, Pete Peterson, Jerry McCarty
- Minutes for 2/15 meeting accepted with modification, appreciation to Marie Nolan.
- Lee expressed appreciation to all for work on submitting Annual Report, and to Cynthia in particular for her leadership, during his absence last month.
- Green Communities – Jerry McCarty
- All items sent in to DOER, and approved by them, awaiting authority to proceed
- Then will proceed with contract with RISE
- Lighting: would take a couple of months. Fred: didn’t review the screw-ins for exterior of library and town hall.
- Retro-commissioning at Middle School: software, which is browser-based, gets installed by Trane 2-3 wks; then couple more weeks to adjust; then hand-off to retro-commissioning agent, Stephen Turner Inc.; training would be by Trane, in two segments: one soon and other in fall. Lee suggests the training be scheduled in advance, for whoever might benefit from it. Process will identify: control issues, which will be covered; but also hardware failures, which will require fixing, probably with outside contractor and funds from other than grant. RISE will produce the report of energy savings projected as a result of retro-commissioning work.
- Paul: when is next GC cycle? We have to completely spend / finish this set of measures before we can submit for another round.
- Next round, a high priority is DHW at Middle School: existing system is heating 2000 gal of water heating, even though we’re only using about 400 gal/day; needs replacing (22 years of a 20-year lifetime); perhaps go to two 100 gal high-efficiency. Fred recommends looking into solar DHW.
- High School retro-commissioning did not make it into FY19 budget, but will be, hopefully FY20. We were not given a reason why DOER rejected this; Jerry will ask why. Perhaps the Middle School retro-commissioning results will provide further justification, either to DOER or in town.
- Cynthia: we should apply for behavioral training, so that teachers and students gain in awareness.
- DPW Solar – Jerry McCarty – Received a proposal from Solar Design Associates (Ashley Deitrich) for ~$27,000, for design work, RFP prep, bid support, systems commissioning. Jerry has asked for clarification, detailed wording, awaiting response. Bid will be in components: base bid (North roof), two alternates (flat South roof, hip Central roof). Permanent Building Committee will look at the construction details. Jerry was a little surprised at price, as SDA had already looked at the building for a design-build bid.
- Street Lighting – Jerry McCarty -Jerry still needs to connect with George Woodbury, to ask him for recommendations about fixtures. And ask a few particulars: what if a few new poles or fixtures are needed? And how to ensure that maintenance costs will stay constant (reviewing Franklin situation). Lee: we need to move ahead with all due haste.
- Canopy photovoltaics – Lee -Would like to see PV canopies, perhaps on walkway between HS and Middle School, also over parking lots, also with EV chargers in parking lots. Superintendent would like to see a bit more study on this; and watch out for student drivers. There is funding for both EV and PV. Lee will pursue. Cynthia suggests pitching this as an educational opportunity; with a dashboard.
- PV on roofs of Middle and HS? Jerry: High School due for a partial roof replacement (over gym etc.), the newer area might be strong enough for PV; Middle School due for roof replacement; roof structure might need strengthening.
- Dale Street replacement building: Jerry: when it is time, q would arise: will it be solar? or solar-ready? MSBA, which funds schools, generally will not fund solar either way; Energy Committee would want to weigh in.
- Mass Energy Insight: Jerry still filling some in some areas.
- Jerry’s 20-year Capital Plan (500+ pages): includes a lot of energy-improvements, for instance improving roof insulation, better windows, HVAC equipment, etc.
- Next Meeting: Thursday April 19.
Minutes respectfully submitted by Fred Davis.
