Summary

A local resident, Mike DeFranco, urged the board to hold design firms accountable for HVAC failures at newer schools and argued the state electric-bus mandate would impose high costs and operational risks; he offered to help the district pursue legal or state-level pushback and promised to share his analysis.

During the public-comment portion of the April 27 meeting, resident Mike DeFranco (introduced by the chair) raised two distinct concerns: apparent HVAC design failures at several newer schools and opposition to Connecticut's electric-bus procurement timetable.

DeFranco, an engineer with HVAC experience and a local parks-and-rec volunteer, said he reviewed capital projects and questioned why recently opened schools would already be listed in CIP funds for mechanical fixes. He said design firms had not accounted for local humidity/dry-bulb conditions and argued the district should consider holding designers accountable for "design failure." He told the board he had discussed the topic with district staff and offered to help the district pursue legal remedies if warranted.

On the electric-bus mandate, DeFranco said he opposed the state's timetable (which he understood to require certain districts or areas to acquire electric buses by 2030) and presented back-of'envelope comparisons of capital and infrastructure costs: he cited per-bus prices (which he reported as roughly $419,000 for EV vs. $225,000 for diesel in his analysis) and warned of additional expenses for chargers, transformers (long lead times) and operational constraints in cold weather. He also cited reported vehicle-fire incidents with EV buses and questioned local fire-department readiness. DeFranco said his analysis suggested a multi-million-dollar extra cost over vehicle lifetimes and volunteered to share his report with the board and state representatives.

Board members thanked him, requested his materials and asked administration to consider his findings and coordinate with other districts and the state. The superintendent labeled the mandate "an unfunded mandate" in the ensuing discussion and noted other districts had experienced procurement and operational pacing challenges.

The board did not take formal action on either concern during the meeting but asked that staff study the points raised and that DeFranco share his supporting materials.
