0:11One of the most notable aspects of the meeting was the emphasis on sustainability in the design of the new Shaker Lane Elementary School, which will cater to pre-kindergarten through second grade and is expected to accommodate 435 students. A significant portion of the conversation revolved around making the building “photovoltaic ready” and “electric vehicle ready,” ensuring that infrastructure for solar panels and electric vehicle chargers is incorporated. This aligns with the community’s expressed interest in sustainability, as highlighted by a recent survey. The project is estimated to receive funding from the MSBA, covering 30 to 35% of the costs for achieving the LEED certification, which emphasizes energy efficiency and healthy material selection.

The architectural firm and various consultants involved in the project presented their plans, which include constructing a two-story building with community-accessible spaces such as a gymnasium and cafeteria. The old school will be demolished and replaced with playing fields. Charlotte Dolan, a resident and member of the sustainability committee, noted the project could serve as a practical example of Littleton’s ongoing efforts in sustainability, complementing the town’s developing climate action plan.

18:54Energy efficiency was another main focus, particularly concerning the energy use intensity (EUI) of the new building. Establishing an EUI target early in the design process is crucial, as it guides the design team in optimizing energy consumption relative to square footage. The MSBA’s baseline requirement is to meet the Massachusetts stretch code, aiming for an EUI target of approximately 25, lower than the typical 75 for existing schools. This aggressive target aligns with current trends in school projects, though achieving it demands considerable design effort.

Discussions also touched on Littleton’s classification as an “IM” municipality, which affects its eligibility for certain utility incentives. Despite this, the project could still benefit from Mass Save incentives. Electrification emerged as a key topic, with participants exploring the transition to an all-electric power building to eliminate fossil fuels. This aligns with state directives promoting sustainability.

39:10The choice of heating and cooling systems also generated considerable debate. Three options were presented: a distributed maintenance system with numerous smaller components, a system utilizing roof-mounted equipment, and a geothermal energy system. While the first option has lower upfront costs, it locks the district into a single manufacturer, complicating future repairs. The second and third options differ in heat sources, with the latter offering energy savings but at a higher initial cost. Participants discussed the need for a cost-effectiveness metric, considering long-term expenses like energy recovery and replacement costs. The community’s decision will likely prioritize affordability while balancing sustainability goals.

18:54Concerns were raised about the financial implications of pursuing an all-electric system, particularly regarding the necessary infrastructure upgrades for future electrification needs. Participants clarified that having a natural gas or diesel generator for emergencies would not disqualify the building from being categorized as all-electric. The implications of evolving energy codes were debated, with some expressing concerns about their restrictive nature and others noting the benefits and feasibility of an all-electric future.
