The board’s debate on the geothermal system’s viability was a central point of discussion, sparked by concerns regarding the system’s resilience and maintenance costs. Members discussed the need for more data and research on the performance of geothermal and all-electric Net Zero buildings, comparing them to other building types. The consideration of a hybrid system was suggested for the new elementary school, prompting plans to present and discuss different HVAC system options at the next sustainability committee meeting.

Another topic of significant concern was the potential relocation of students during the construction of the new school building. The board scrutinized the feasibility and desirability of moving the students off-site, with members expressing skepticism about the acceptability of this approach to the school community and concern over the psychological impact on students and parents. Despite these reservations, the benefits of relocation were also noted, including the potential to expedite the construction timeline and minimize disruption. The debate extended to the duration of the relocation, with varying opinions on the timeline and the evaluation of different design and construction approaches for the new building.

The meeting further addressed the preliminary findings of the geotechnical investigation, which revealed the presence of fill and buried organic soils at depths between 2 and 8 feet, necessitating removal from the building footprint. Groundwater was found at 6 feet below grade. Discussions included the implications of these findings on the foundation design and the suggestion of conducting a geothermal test well to assess its practicality.

The board also reviewed the PDP report’s table of contents, evaluating alternatives and suggesting the addition of sustainability goals related to recyclable materials.

Delving into the architectural aspects, some members raised concerns about the older feel of the schools, while others saw positives in the layout and design. The importance of having tight building envelopes and considering different heating systems was agreed upon, with the notion that open debates are valuable to challenge existing ideas and ensure the best outcomes.

The Reading Select Board also examined the complexities of sustainable technology, including long-term operating costs and the challenges of building automation. The balance between first costs and long-term operating costs was debated, as was the need for proof that sustainable technology results in lower operating costs.

As the meeting progressed, the board reviewed the OPM report and financials, noting that the project was on schedule and under budget, with no budget adjustments or changes to contracts. A motion to approve project invoicing for feasibility services was passed, and future agenda items and meetings were scheduled, with the next meeting set for June 17th.
