Energy use by building

MEC

The Medfield Energy Committee is working on crafting a plan to reduce town energy consumption by 20%, in order to qualify as a Green Community (and thereby pick up our $148,000 state DOER grant monies).  As part of that process, the MEC is gathering the data on what buildings and uses use what amounts of energy, and also asking departments for recommendations on how to their reduce usage.

The MEC reports the following current existing energy use by building or use:

Facility (copy) Use (MMBTU) Cumulative MMBTU % of Total
Medfield High  14,030 14030.15 26%
Blake Middle  8,766 22795.707 43%
Dale Street Elementary  5,423 28219.128 53%
Diesel  4,366 32584.979 61%
Memorial Elementary  4,268 36853.056 69%
Wheelock Elementary  3,497 40350.473 75%
Water Pump Stations  3,213 43563.181 81%
Wastewater Treatment Plant  2,959 46522.418 87%
Gasoline  2,952 49474.362 93%

WWTP solar analytics

The solar installation at the Waste Water Treatment Plant went on-line recently, and residents can now track how much electricity it is generating for them.  This was the email today about access to the on-line analytics, which are really pretty cool.  The school kids would love to see how much electricity is being generated, and the global warming savings it causes –


Good morning everyone,

 

Below is the link to view real-time production of the solar array.  The initial screen will show the lifetime kWh production and instantaneous kW output.  The “Site Analytics” tab will allow you to view historic data.  (Note: there is only one week of historical data available as that data logger was only recently installed.  However this doesn’t affect the lifetime kWh number.)

 

http://www.solrenview.com/SolrenView/mainFr.php?siteId=4234

 

FYI we pay approx $0.13/kWh, so as of today we have saved $5,600 in utility costs since the system came online.

 

Best Regards,

Andrew

Energy use by building

The following data on energy use by the various town buildings was presented to the selectmen Tuesday evening by Andrew Seaman, Facilities Manager.  I found the second graph especially interesting, as it presents the energy use per building size.  Andrew indicated that there  were start up problems at the Garage which hiked up the natural gas usage, and that this past winter I believe he indicated the usage was about half what is noted here.  The Pfaff Center is not surprising, given its age.  The national average energy usage for schools Andrew as being 59 KBTO/sqft/year, but many of those schools do not have our winters.  The Center had high usage for a new building.  The Wheelock school is amazing at how energy efficient it is, given that it has single pane windows and has to be fifty years old.

On the first slide I noted the high energy use by water pumps, and Andrew said that is almost entirely well 6 (off Rte. 27 at the Charles River), which is our most productive well and most used well – it takes a lot of energy to move that water up into the water tower.

The third slide was the real reason for Andrew’s presentation, as the town needs to have a plan to reduce our energy usage by 20%, over our base line year, as the last item needed for our qualifying under the Green Communities Act.  Andrew was gathering the actual energy use data in order to craft the plan on where that next 20% savings could be found, and that is what he has started to set forth in that third slide.

The Energy Committee made the current 20% reduction task tougher for the town by virtue of the fact that the Energy Committee’s initiatives have already reduced the town energy usage by 30%.

Finally, please know that I did rotate the slides before I saved and uploaded them, but still ended up askew.

Medfield home solar PV

solar on house

The Medfield Energy Committee (MEC) has sponsored a SolarizeMedfield program to assist home owners in town to group together and thereby increase their buying power, so as to get lower rates from one solar PV installer, that the MEC will select from among those who apply.

SolarizeMedfield is being run for the town by the gracious efforts of Marie Zack Nolan, a LEED certified engineer with The Green Engineer, LLP in Concord, a former Warrant Committee member, and the long serving original chair of the MEC.

Medfield’s 1st solar PV

Representative Shawn Dooley reads a Proclamation from the Legislature, with Mike Sullivan, Jeremy Marsette, Mark Fisher and my better half (I barely made the photo) looking on.

Medfield First Solar PV Array opened at the Waste Water Treatment Plant on 4/28/16

The new 237 KW solar PV array at the Waste Water Treatment Plant went online after a ribbon cutting yesterday.  This opening was the combined achievement of Energy Committee member Fred Davis obtained a $12,500 state DOER grant for the town in 2014 that allowed the Committee to study solar options in three town locations, the Waste Water Treatment Plant Operator, Bob McDonald, getting a $180,000 state grant for almost half the construction costs, and the Energy Committee pushing the project forward to completion via eh efforts of its staff person, Facilities Manager, Andrew Seaman.

It is actually a hugely instructive lesson in how important a paid town staff person is to a volunteer town committee, as this whole process did not really take off until Andrew was hired and began to staff the Energy Committee and its meetings.

Solar PV – X3

solar PV-2

The town is jumping from having no solar PV arrays at all, to soon having two, and potentially three (if town meeting agrees on Monday).

  • Waste Water Treatment Plant – The 237KW  solar array at the Waste Water Treatment Plant is already constructed and scheduled to  start electricity generation following the ribbon cutting next Thursday at 10AM.
  • Public Safety Building – The new Public Safety Building was designed for a roof mounted solar array, but installing it was not part of the original bids due to concerns over adding to the costs.  That array was previously going forward as a 63KW roof mounted solar array, funded via a change order, spending some of the construction savings, until the state recently allowed the its incentives to run out, at which time that array was put on hold.  When the state legislation recently extended the state incentives, the economies of that array became attractive again, so that array has again been put on track to proceed as a change order to the original contract, spending some of the unexpended contingency monies to do that installation.
  • DPW Garage – The DPW Garage was designed solar ready, and the Energy Committee has been looking at doing a 150KW solar array there too, but that plan was also held in abeyance by the state allowing its incentives to expire, making the return on solar PV arrays less attractive.  There is $240,000 of appropriated monies left over from the solar array at the WWTP, the cost of which came in a lot under budget, and those monies are the  subject of  the ATM article 24 – to allow the transfer of those funds to be used for a solar PV array on the Garage.  However, the estimated cost of the Garage solar array is $383,000, so the project was about $150,000 short.  Mike Sullivan and Martha Festa, the Warrant Committee chair, yesterday crafted a solution, an amendment to the operating budget at the ATM, as the mechanism to obtain those monies at this late date, which can allow the Garage solar array to proceed.

The timing of the Public Safety Building and DPW Garage solar projects is important because the state incentives are going to change at  the end of 2017, making the economics of such solar arrays less advantageous – so because of the recent legislative changes, it became a do it now or not at all proposition.
