ECEIVE' 3333 33 IIMair„ X333 aii,n Sustainable Lexington Committee Minutes of Meeting of February 1, 2022 t.EMG"TO N MA A meeting of the Sustainable Lexington Committee (SLC)was held by Zoom conference. A quorum of five was present throughout. Members Present: Cindy Arens, Celis Brisbin, Paul Chernick, Todd Rhodes (vice-chair), Dan Voss (Chair) Members Absent: Archana Dayalu, Rick Reibstein, Charlie Wyman Staff Present: None Other Attendees: None The meeting was called to order at 7:13 pm. Todd referenced the opening statement requested by the Town Clerk, and all members present responded that they could hear. The focus on the meeting was to prepare for the joint meeting with the Permanent Building Committee (PBC) on Thursday (2/3). • Dan Voss provided an update on his discussions with members of the PBC and the Director of Public Facilities regarding the solar options for the Police Station and other sustainability elements. • The options include sufficient solar for the Police Station to be net zero emissions. • About 650,000 kWh per year would be sufficient for the building needs and potentially for charging electric vehicles. • Dan presented CAD models showing versions of the options: o The canopies in the back would be sufficient to meet net zero. o The canopy on the side would support vehicle charging • A key objective would be for the infrastructure (electrical systems, conduit, etc.) in the building and parking area to be sufficient to support the net zero option—regardless of the option selected. o Including infrastructure for energy storage. Need to identify a location for the storage and central inverter bank. • The net zero option would add about$16,000 per year over the cost of the system for the first 20 years and then about$50,000 per year in subsequent years - $750,000 cumulative positive cash flow. • The group discussed the role of the Historic District Commission (HDC) in approving the design and the resilience benefit of on-site solar. • On Thursday, the objective is to discuss timeline for approval and how to integrate solar into the design. • The committee discussed that the goal should be to build the Police Station with solar. Incorporating solar as part of the initial design is the lowest cost method for integrating solar.
