Introduction: Refer to attendees list. 2. Please refer to attached presentation for meeting materials. SMMA introduced team: Lorraine Finnegan Project Manager Matt Rice Project Architect Verirr pint: I pass aa..lhaa.aset:t:s �AIVw AA(.da)reandW/atl iit:..aierr,,cov a Martine Dion Director of Sustainability Andy Oldeman Director of Engineering Anthony Jimenez Electrical Engineer Rebecca Ra milow Project Manager for Sustainability Vamshi Gooje Principal in Charge for Sustainability SMMA team states that the first meeting today is to go around the room to each focus group member,hear what they are concerned about,what they want to talk about and goal at next meeting is to answer the questions and concerns. SMMA presents the focus group objective: Review preferred MEP systems,sustainable design features,healthy materials, environmentally friendly design and renewable opportunities. Focus Group Timeline: At the first meeting the agenda is to listen,at the second meeting to review and respond,at the third to confirm and recommend,and the fourth to reconvene with all of the focus groups. SMMA explains that the project is currently in the PDP phase with the MSBA. They explain that a PDP is the Preliminary Design Program process. During this project the District and its team collaborate with the MSBA to: Document their educational program Generate an initial space summary Document existing conditions Establish design parameters Develop and evaluate alternatives Recommend the most cost effective and educationally appropriate preferred solution SMMA reviews the project sustainability givens: MSBA Green School Policy: • Base: LEED Silver, Stretch Energy Code, MEP/BE/Ongoing LEED Commissioning, 3LEED MR/IEQ points * 4%Additional Reimbursement: Specialized stretch code (3%), and 5 LEED MR/IEQ points Massachusetts Specialized Code • Full compliance with the standard stretch energy code • 3 pathways: o All electric HVAC and DHW pathway o (2)fossil fuel heating pathways o Electrification of heating readiness o Renewable energy Lexington Integrated Design Policy • SBC voted 9/14/23 o LEED Gold minimum o Target Platinum o All electric heating and cooling systems o Resilience Level 2(field house/gym), level 3 (remainder) • PBC Recommendations: o EUI 25% or 30% >ASHRAE 90.1-2019 o Net zero energy o Optimize renewals on-site o Battery storage analysis SMMA presents draft LEED scorecard and explains will further review at next focus group meeting. C.Arens: Thinking about the future Page 2 of 6 Separate metering for water systems and electrical systems Measure what the building does Doing this ahead of time Tie maintenance into educational possibilities Low toxicity and avoiding red list materials Reusables outside of cafeteria, lounges What is embodied carbon?Teach students Potential for bus batteries to increase resilience Being cognizant of expansion of the systems that need to support the building Micro rhythms, educating students C. Bouchard: Goals cutting edge building latest MEP technology Integration, all electric renewable energy Net zero Batteries EV charging stations A lot of communication and collaboration with utilities Building orientation maximize solar Consider best system: life cycle cost analysis,geothermal, air source, utility costs, service, maintenance 4 pipe and 2 pipe and lessons learned Simultaneous cooling and heating at same time Backup for systems Closed loop, open loop, wells, and maintenance Heat pumps designing can be used on coldest days, etc. 10 years from now on the type of systems Electrical sub meter, plumbing sub metering, leaking,valves to shut off etc. to mitigate loss P. Coleman: Agree with Chris Bouchard Challenge for group and project is to integrate so many things into one project That itself is a lesson learned Recent schools, lessons learned, geothermal, important to get data from recent schools and bring it forward into discussion on how the design will land at the end of day Overlap with tomorrow committee with design group, efficiency of outside wall tie to mechanical to everything All interest of the town to get the best value Cutting edge design to make sure right value for every dollar spent J. Himmel: Site security safety focus session Million dollars in operating costs could save with right solution EAU Identify operating costs Design The beyond That could deliver annual sales IDP explore options as early as possible Solution not something that's simple but integrated Page 3 of 6 Tech at 1 st life cycle Grants utilize and optimize Open PBC/SLC work session to explore the beyond the usual business Explore parameters of grants programs, life cycle, beyond business and usual Consultants explore solutions then presented to PBC and SLC before SBC Viable solutions 3rd step V. Leroy: Theater spaces larger supply of electricity Full rigging in space fixtures to allow for service Storage spaces and mechanical areas that house these items 24/7 HVAC and humidity control A.Mele: Students' representation and aware of what's happening in the project Encourage team to get the word out and get them to contribute and be transparent about project S. Newell: Echo Chris Bouchard Viability of ASHP(air source heat pump) in the next 5-10 years and repairs on them Integration of all these systems into one specific area and sensors, security, and look at larger system G. Parker: Goal to serve town meeting on recommendation on spending of the proejct Initial cost and ongoing costs Need robust systems that are efficient and easy to maintain M. Peard: Lexington place to eager to push envelope in sustainability Not just todays best practices but beyond Emerging technologies Transportation: car traffic, easy egress and encourage students to bike or walk to school Transition to electric school busses EV chargers Curriculum that students can learn from the building Monitors in the school Outdoor connection and learning spaces T. Rhodes: Town will have electric school buses in the future Don't have a place to charge them Could be offsite to charge And could be integrated into the high school Batteries would support the building as well Needs to be early in the process M. Sandeen: Goal of IDP is for health of students and staff If there is a tradeoff between energy efficiency and health,we will go towards health as a priority Page 4 of 6 When we model what we need for energy storage systems All of decisions are made for health of students and staff Recommendations from DPH and board of health 600 million CO2/3 megawatts of solar would be needed Sensors in the building air quality so they can respond to it Ventilation is quite large No amount of ventilation gets rid of the toxins in the walls, carpets, etc. red list and offset of the materials being used Significant upfront agreement with utilities Make sure have enough energy storage and integration system agreement Need an hourly energy model at very early stage Modeling heating and cooling load S. Shaw: Increase transparency for students Renewable energy EV charging stations Heating and cooling in building is very inconsistent Important to build green spaces for students to interact with nature N. Sofen: Green infrastructure is the only infrastructure that doesn't depreciate Incremental but important accomplishments Use of trees for shading, cooling, wind Sustainable sites would be helpful in deciding where to site the school Health of students Creating outdoor spaces Look at on tree design??To figure out where to plant trees Landscaping to provide shade and lower air temperatures Use of native plants J.Tung: Support healthfulness to minimize detrimental materials Air quality and ventilation is important for health Access to outdoors is important Preferably away from roads Exposure to natural light indoors Acoustic comfort, mindfulness of noise levels Consideration of maintenance of the structure D.Voss: Timing is critical when thinking about incorporating sustainability elements Making building solar ready Putting in infrastructure for solar EV Designing building to be ready for storage Not solutions that can be tacked on afterwards without significant cost Ask ourselves about the cost of implications of delay L.Jensen: Solar ready building is critical Page 5 of 6 Should strive for net positive Creative roofline pitch facing south Canopies Awnings Massing of building- utilize space for multifunction's Combining spaces that aren't occupied at the same time to reduce energy use Have one wing without geothermal to allow for expansion M. Sandeen: Local bike store owner Selling 3 times as many e bikes as pedal bikes Storage for e bikes are bigger and security measures/charging Next Steps: What to expect in meeting#2: Objective:The design team will speak on the topics below as well as the priorities brought up by the focus group today Topics: Lexington Public Schools experience with systems-best practices and lessons learned All electric MEP systems Renewable energy Net-Zero Energy Exterior Materials& Massing/Orientation Embodied Carbon Healthfulness Interior Materials, indoor air quality, access to daylight and outdoors Sustainable Sites 3.
