Dan Voss (chair), Charlie Wyman
Members Absent: Archana Dayalu, Rick Reibstein
Other Attendees: Stella Carr(Sustainability Director), Joe Pato (Select Board), Mark
Sandeen (Select Board), Mike Cronin (Director of Public Facilities),
Shawn Newell (Asst. Director of Public Facilities), Chris Bouchard
(LHS Facilities Manager), Paul Brown (Project Director, Gordian),

The meeting was called to order at 6:00 pm. Todd referenced the opening statement requested by
the Town Manager, and all members present responded that they could hear.
1. Comments from residents; New business
There were no comments from residents or new business raised.
2. Presentation of Capital Planning Tool(M. Cronin, S. Newell, C. Bouchard, and P.
Brown)
• The team from the Department of Public Facilities provided an overview of the capital
planning tool being implemented by the department to support the development of a 20-
year facilities capital plan. The database tool is designed to assess the condition of
existing facilities, evaluate each building based on the Facility Condition Index, and
generate estimates for the cost to maintain/update the facilities over the planning time
horizon. Key terms include:
o Current Replacement Value: the sum of the Asset's System replacement costs derived
from RSMeans construction cost data, localized to nearest major city, in this case
Boston, MA. Does not include site acquisition and preparation, landscaping,parking,
moveable furniture and equipment.
o Facility Condition Index (FCI)is the ratio of the cost of the Asset's improvements
identified as needed in the years (Requirements) divided by the Asset's calculated
replacement value (CRV) and expressed as a decimal fraction of one.

• The team identified that the tool could also assess the performance of Town buildings
based on "Sustainability" factors such as energy efficiency, building materials, indoor air
quality (air exchanges), etc.
• S. Newall identify that Paul Brown (Gordian), who had to leave the meeting earlier,
would be able to work with the Committee and provide a more complete description of
how the"Sustainability" elements of the modeling would work. Several points to
consider included:
o The tool could consider materials, rooftop units (for air exchanges), etc. to be
replaced beyond the standard system replacement.
o The tool helps you work through the cascading number of changes that would be
affected by the decision to change certain elements of a building.
o The cost to add this assessment to the current modeling would be 5 to 6 cents per sq ft
($90,000)project to assess all buildings for sustainability; however:
■ Not all buildings would need to be considered: New buildings would not need to
be assessed immediately because they have been built to the Integrated Building
and Construction Policy, and old buildings (planned for replacement)would not
need to be assessed..
• Q&A with committee members and guests included the following:
o D. Voss: FCI is similar to PCI(Pavement Condition Index)being used by the Town.
He would like to see how desired outcomes of our buildings (health, energy,
emissions) are factored into the prioritization for capital improvement.
o D. Voss: To do that, we need a performance policy so that we know how the
buildings perform against those objectives and establish a performance index. He
thinks of them as "high performance outcomes" not"sustainability" outcomes. We
should prioritize this with the Town Manager.
o C. Arens: Were there any surprises?
■ Facilities: We know what we spend so not too much of a surprise there, but it
does help to prioritize what to work on first. Also, it identified that we're not
spending as much on capital improvements as what the model suggests is needed.
o C. Arens: How may people have access to the database?
■ Facilities: There are two levels of access. We can allow you to work in/view the
database, but only a Facilities staff would have access to change data.
o P. Chernick: How do you use the tool to decide whether to replace or upgrade?
■ Facilities: There's a lot of data in the tool and they are working to see how best to
address that question. They have made similar decisions in the past(e.g., the
2.
Sustainable Lexington Committee Minutes of June 22, 2021
Town did that with Bridge and Bowman—they bought some time on
replacements by making selective investments).
o C. Brisbin: RSMeans doesn't include rebates and other funding sources. Is there a
way to address that?
■ Facilities: Given the disconnected timing of capital planning and grant
applications, that would be difficult. The model will help us understand the
requirements and costs and once a project gets close, we can do a better job of
seeing how to best fund the work.
o C. Brisbin: ROI positive projects should be done anyway.
■ Facilities: It's a great question. They are looking at how that is assessed in the
model, but we haven't gotten there yet.
o C. Brisbin: Not all buildings need to be in A condition. It can be better to keep old
buildings running than to build a new one that more energy efficient.
■ Facilities: Paul Brown brought this up also.
■ P. Chernick: Is there a metric for how much efficiency you need to balance out
the impact of imbedded?
o T. Rhodes: Building on Dan's comment, we need to set up the objectives against
which to assess performance.
■ Facilities: Paul Brown can provide that input on that process but the Town needs
to set those objectives.
o M. Sandeen: Maybe change "A" to "New" to avoid the bias people have toward
wanting"A Condition" buildings.
■ Facilities: The chart does have other descriptors along those lines that could be
used.
• The discussion concluded with the agreement that a subset of Committee members will
meet with Paul Brown and Facilities staff to discuss the opportunity further. This
discussion will include assessing how to establish the objectives.
3. Sustainability Director's Report
• EV101 web-event was very successful with 70 attendees.
• A Water Conservation webinar is planned for July 14th
• The Town Manager is setting up a Working Group is being planning for reconsideration
of the Hartwell Innovation Park(Article 45)bylaw for the Special Town Meeting.
o C. Arens received an email from Jim Malloy about participating in the Working
Group. She is waiting to hear from Amanda Loomis for more details.

4. Review of the Sustainability Plan Sector priorities /Climate Action Planning Cohort. (S.
Carr)
• S. Carr shared the latest version of the memo. She had already re-ordered the topics based
on earlier feedback. The Committee had approved the content of the memo in a previous
meeting. S. Carr will share the memo with Town management.
5. Consider whether to join as a partner on the new GWAC website.
• R. Pappo identified that following their strategic planning review, GWAC re-branding
and will soom be launching a new website. As part of their objective to collaborate with
other organizations, GWAC would like to identify the Sustainable Lexington Committee
as a Partner on the website along with other organizations.
o Other organization that will be participating include: LPS green teams and Lexington
Living Landscapes. There will be to list the Partners and link to their websites.
• P. Chernick asked whether it appropriate for SLC to be a partner. R. Pappo identified that
the Sustainable Lexington Committee is part of the Green Action Network, which is
similar.
• The Committee voted 5 — 0 in favor of the motion to: Approve adding the Sustainable
Lexington Committee as a Partner/Collaborator on the new GWAC website pending the
approval by Joe Pato (as the committee liaison) and/or the Select Board.
• R. Pappo will share an overview of what she is envisioning for the website with S. Carr
to share with J. Pato and Town staff for the final approval. S. Carr will also let R. Pappo
know if the Sustainability Department can be included as a Partner.
6. Discussion of Building Energy Use Disclosure Ordinance(BEUDO) -follow on
discussion from last regular meeting.
• S. Carr had been looking into an arrangement with Concord where the two towns could
share administrative responsibilities for a BEUDO program, but her contact is no longer
at Concord. She is looking at other options because the program would require a lot of
work and the benefits are uncertain. A future Net Zero building code could add these
types of requirements, but that could be a long way off.
• C. Arens spoke in support of a BEUDO program because it is a good way to start the
conversation with businesses and it's hard to get data about these buildings. The program
would be easier to get passed if it starts with just reporting and then adds performance
requirements later. It would likely affect only 50 —70 buildings in town. Also that it's
important for town to keep pushing because the state is slow.
• C. Brisbin stated that a BEUDO is valuable because data feeds decisions, but we need to
decide how much data is needed and we have limited bandwidth. He mentioned that we
have enough data to make many of the decisions that we need to make. He suggested that
we could do modeling rather than what Boston and Cambridge are doing and use a green

building calculator for the top 60 buildings and to get a good idea of building's
performance..
• T. Rhodes mentioned that Mark Sandeen had suggested at one time that we run a
program more like the Paris Climate Accord where commercial building owners would
present their own building performance goals, using their own format on a regular basis.
It would be a voluntary program and the data would not be consistent across companies,
but it would be easier to implement.
• J. Krieger commented that it's important to get the data from the major buildings—
commercial and major residential. She would like to see it happen.
• R. Pappo suggested that Arlington could a potential partner.
• The discussion concluded with the agreement to keep this topic on the agenda at future
meetings and for S. Carr to talk with colleagues in neighboring town about being
potential partners.
7. Heat Pumps - update on the grant that the Town is pursuing and other actions to
promote heat pumps.
• Stella explained that she is working with Abode on a Mass CEC EMPOWER grant for
targeting heat pump transitions in priority populations in Lexington. She learned that the
program is most interested in priority populations (low income, elderly, etc.), and she is
exploring what populations might make the most sense and how to target them. She will
also try to apply this fall for one of the Green Communities grants for community
outreach.
• Some discussion followed, with a number of points raised. It was noted that many of the
homes that might be targeted may not be good candidates for the program as they are
about to become tear-downs in Lexington's housing market; how do you evaluate this? A
focus on air conditioning, and not just heat, might be productive. Marcia noted that an
Energy Fair this fall will focus on electrifying everything. Are there situations in which
adding on might be preferable (including with respect to embedded carbon)than
demolition and rebuilding? Celis raised the question of whether tax policy could
encourage smaller and more energy efficient homes; Paul replied that current state law
sharply restricts what towns can do with property tax policy.
• The discussion concluded with the agreement to keep this topic on the agenda at future
meetings.
8. Discussion of Concord's proposed ban on the use of neonicotinoids on town-owned
property.
• Ricki described the bylaw Concord recently enacted banning the use of neonicotinoids on
new leases of town-owned land. This prompted a discussion of whether a similar ban in
Lexington (or expanded to all Town property) might be pursued, and whether Town
Meeting action or policy adoption by relevant town boards and departments (including
5.

town procurement policy) might be the better route (or both). Stella will inquire about
neonic use by DPW; Charlie will ask about the Conservation Commission's leases and
any policy on neonic use.
9. Discussion of gaps in solar/renewable electricity generation/sourcing and approaches to
close those gaps.
• Todd walked the committee through the early stages of a report being assembled by
Todd, Paul, Celis, and Dan that looks at electricity use and trends and describes priorities
for sourcing of electricity and other renewables. Todd requested feedback at this stage
primarily on the draft priorities. The major bit of feedback voiced by members of the
committee was to push greenfield development in Lexington further down the list. The
list identified installing solar in Lexington as the first priority and included greenfield
sites as the last option within Lexington. Feedback from committee members
recommended that sites outside of Lexington be considered before greenfield sites within
Lexington are considered. Marcia raised the question of siting solar on highway sound
barriers and under high-voltage power lines.
10. Update of the Town's emissions report.
• Cindy presented her preliminary conclusions after attempting to update town emissions
numbers. Examining the period 2012 to 2019, she found that emissions are down 4%,
electricity usage is down 6.5%, electricity emissions are down 33%, and fossil fuel
emissions (what we're burning in town)is up 22%. There are data anomalies and one-
time factors that make long-term definitive conclusions difficult. She also looked at what
redevelopment of Hartwell could add to the numbers, and found a significant increase if
redevelopment proceeds without controls on fossil fuel use.
• Mark noted that thanks to recent work by National Grid, Lexington is no longer on the
list of the 20 Massachusetts municipalities with the highest emissions from large gas
leaks.
Next Meeting: The next regularly scheduled meeting of Sustainable Lexington is at 6 pm on July
27, 2021.
The meeting was adjourned at 9:15 pm.
