Lexington Ma: Page 2 of 8 Project: Lexington High School Meeting:School Building Committee Meeting No. 27-03/24/2025 Page:3 o Asked when there will be a schedule for the Article 97 land swap o Asked for the cost for converting the central office space into classrooms 27.4 Confirm Spaces to be Air Conditioned Record • L.Finnegan shared a diagram of what spaces will not be air conditioned as it is easier than showing what will be which is most of the space (Slide 7) • A.Levine asked if this means that stairwells are closed off? C L.Finnegan noted they will have doors on hold opens and will be ventilated • A.Baker asked if the WON doors will be included in the project? o B.Black noted there has not been a choice made on that yet but they are recommending the three main stairwells have these at the top. • C.Favazzo asked if the stairwells have their own HVAC units? C L.Finnegan noted they do not • J.Himmel asked if any of the spaces deemed not to be air conditioned would be repurposed in the future that would need it? o L.Finnegan noted that the only one she could see being converted is the storage room near the auditorium but it is unlikely as it is the main storage area. • A.Levine asked what it means for them to be included in the air conditioned o L.Finnegan noted that the air duct size would increase,the energy model would change as the spaces would take more energy total,and they would have to bring the cooling pipe to those spaces. o A.Levine asked what the cost would be to air condition the field house? • L.Finnegan noted she is not sure but can get that cost • K.Lenihan asked if our climate was closer to Virginia would the stairwells need to be air conditioned with warmer weather. o L.Finnegan noted she is not sure but would think no as they are just passage areas • J.Pato noted that he is concerned with the aspect of the operational costs including the field house as it will increase the total electrical needs of the building and if it will have a serious impact on the models? o A.Jimenez noted he is not able to answer that currently • C.Favazzo noted they need to know what it means for the design plan for including the field house • H.Min Sha noted that if the expense is small it would be worth it to just air condition it all but it may be easier to just leave them unconditioned (stairwells) • A.Levine noted that it does not seem like the stairwells should be air conditioned Page 3 of 8 Project: Lexington High School Meeting:School Building Committee Meeting No. 27-03/24/2025 Page:4 • K.Lenihan noted that the SBC agrees that the stairwells should remain unconditioned • K.Lenihan noted that if the field house is not air conditioned it will be unusable in the summer • J.Pato agreed and said they could plan on having it conditioned and make operational choices of when to use it. • C.Favazzo shared that SMMA and the project team needs to complete the study of including the field house before any choice is made 27.5 Introduce Exterior Design& Building Entrances Record • B.Black reviewed the building entrances for the school starting on Slide 10 West Entrance • Highly visible from Worthen Road-good civic presence • Connected to bus drop-off/pickup • Visitor and accessible parking nearby • Main Office/main security check-in for visitors • Close to Guidance and Student Support hub • Access to Central Office elevator/stair lobby in Wing A • Entrance Plaza Pedestrian Zones should be large enough for mass groupings of students • Plaza Design to frame entrance and develop scale transition • Limited Program East Entrance • Connected to car drop-off/pickup • Visitor and accessible parking nearby • May be used for after-hours events • Should it be used for primary Gym access? • Largest Entrance Plaza -design to frame entrance and develop scale transition • Program Flexibility Field House Entrance • Lobby connected to both Field House and Gym • Visitor and accessible parking nearby • May be used for after-hours events • Should it be used for primary Gym access? North Entrance • LABBB entrance close to drop-off/pickup loop • Limited parking nearby • Smallest Entrance Plaza-potential for intimate gathering space • North facing-more limited planting opportunities • A.Baker asked if the gym competition court is able to be in either location for both entrance options? • B.Black noted yes but it will affect adjacency and circulation Page 4 of 8 Project: Lexington High School Meeting:School Building Committee Meeting No. 27-03/24/2025 Page: 5 • L.Finnegan noted that the image of Wakefield(slide 19)is a rendering not image. She also noted that the Waltham image is about the size of the east entrance. • B.Black clarified that the west entrance is for visitors based on A.Levine's question. • A.Levine also asked how close the dining common tables are to the west entrance • B.Black noted roughly 40 feet • B.Black reviewed the exterior building materials(Slide 22-40) • Potential Material Options and Scope Assumptions Opaque Brick Masonry, Precast • 75%of Masonry Accents, Stone Base Wall Walls Enclosure (-60%of • High solid wall Insulatio area) n Value Rainscreen Pre-finished Metal Accent Walls Panel Spandrels and (-40%of Fascias;Accents in solid wall Porcelain,Terra Cotta, area) Pre-formed Metal or Fiber Cement Windows Triple Insulated-Glazed, • 25%of (-50%of Aluminum Frame Wall glazed area) Enclosure • Utilizes Low-emis sivity glass Curtain Triple Insulated-Glazed, Walls and Aluminum Frame Storefront (-50%of glazed area) Roof Edges Pre-finished Metal &Canopies Soffits Pre-finished Metal, Phenolic or DEFS (stucco) Roof Screens Pre-finished Metal • Performance requirements for building envelop • Window to wall Ratio(WWR)=25% • Wall Insulation = R-40 Page 5 of 8 Project: Lexington High School Meeting:School Building Committee Meeting No. 27-03/24/2025 Page: 6 • Roof Insulation = R-60 • High-performance glazing system • Low U-value:0.23 or better • High Solar Heat Gain Coefficient:0.30 or better • High Visual Light Transmittance • Thermal Bridging Mitigation • Air Infiltration Testing- Reduction Goal=0.15 cfm/sf@ 75 PA or better • M.Cronin asked on the rain screen systems if there is different lifespans for the rain screens compared to just brick • B.Black noted no he does not think that there is a recognizable difference in the systems but some of the surface or panel materials will have different lifespans • C.Favazzo asked for Turner to provide square foot cost differentials and noted they should also be comparing install timelines. • J.Meiser noted that the graph on Slide 24 is pretty accurate even when labor costs are included • C.Kosnoff asked for the axis'to be labeled for the graph on slide 24 • A.Levine asked for a diagram similar to slide 24 where the X-axis is cost and the Y-axis is embodied carbon • C.Favazzo noted the fiber cement brand 'Tactile' he has used before and recommends • J.Hackett asked if the sloped ceiling makes the room feel bigger • B.Black noted possibly but not necessarily, maybe a bump up pocket at the edge for the room would work better but the plan for now is flat ceilings • H.Min Sha is very excited about this phase and think sit is critical for the function of the school and community. He noted on slide 36 he likes the bottom right option the best. Min Sha also shared that they should move away from the classic red brick look. • C.Favazzo asked for the screen walls to be included on all the renderings and elevations going forward as they are part of it. C.Favazzo also asked to confirm what the ceiling height is? • B.Black noted they are currently at 16 feet • C.Favazzo would like to see that down to 14 feet and he thinks that is very adequate • K.Slaysky asked that as the design options are shared with the broader community any extremely expensive options should not be shared and then later removed as a value engineering move • J.Pato asked what the proportion of these materials are compared to the steel and concrete? • SM MA will provide a response 27.6 Introduce Lighted Fields&Field Material Record Page 6 of 8 Project: Lexington High School Meeting:School Building Committee Meeting No. 27-03/24/2025 Page:7 • M.Dowhan shared slides and information on which fields will be lighted (Slide 43-45 • M.Dowhan reviewed the field material(Slide 46&47) C Natural Turf(seed or sod) Pros • Natural Aesthetics • Cooler Surface • Environmental Benefits • Carbon sequestration, reduce excess stormwater runoff • Cost Effective to Install Cons • High Maintenance • mowing,watering,fertilizing, pest control • Water Usage • Durability Issues • Overuse and excessive traffic lead to compaction and bare spots; saturated soils/standing water limit playability • Inconsistent Surface • Pesticide and Fertilizer Use • Seed Requires 2 Full Growing Seasons Before Use • Sod Requires a Minimum of 2-3 Weeks for Root Establishment Prior To Use o Synthetic Turf Pros • Low Maintenance • Durability • Consistent Appearance • Long-Term Cost Effectiveness • Able to Use Field Immediately Cons • High Initial Cost • Heat Retention • Environmental Impact • J.Himmel asked for any comparison costs to be escalated to the project costs • C.Favazzo noted some of the baseball fields will need considerable netting for protecting the road and school from foul balls • C.Sheth asked where the throwing cages will be for the track program? C M.Dowhan noted possibly the outer field area of CA • K.Slaysky asked if the town has a philosophy on using irrigation systems for fields? o M.Cronin noted that the playing fields will probably be irrigated • H.Min Sha noted Arlington has a big local issue with using synthetic turf and asked if anyone on the committee would like it.
