Public Works center overhaul: solar feasibility, EV charging, VFDs and structural evaluations on the 2026 CIP
Summary
The committee reviewed a broad set of Public Works Center projects: PV feasibility tied to federal incentives, rooftop and structural testing, replacement of variable frequency drives and garage doors, movable vehicle jacks, LED lighting, generator panel upgrades and fleet electrification provisions including future Level 3 chargers.
Oak Park Public Works staff presented a multi‑year set of capital recommendations for the Public Works Center at the Sept. 25 finance committee meeting, including design work for solar photovoltaic (PV) on the facility, fleet electrification infrastructure, major mechanical repairs and a structural evaluation of large basement girders.
Solar and federal incentives
Staff recommended beginning design and evaluation in 2026 so the project would be eligible for federal incentives that require at least 5% of materials to be purchased before the July 2026 deadline (staff noted that purchasing 5% of materials by the deadline is sufficient to qualify for a 30% tax/incentive benefit). Structural testing confirmed the Public Works roof can support PV and estimates suggested PV could supply about 30% of the facility’s energy needs. Staff said final economics will depend on detailed design and whether the PV system can be tied into meters that the village pays for directly.
Fleet electrification and chargers
Public Works recommended continued transition of administrative and fleet vehicles to EVs and adding infrastructure capacity now. Staff proposed funding for more Level 2 chargers and included a placeholder for a future Level 3 charger in the fuel island in 2028. The village expects two vehicles per charger as an operational target, with some small departments operating on a three‑vehicle‑per‑charger model if staff coordinate schedules.
Mechanical, structural and building systems
The Public Works Center is approaching 20 years old and staff presented a long list of mechanical, electrical and plumbing (MEP) needs derived from a five‑year periodic condition assessment (PCA). Highlighted items included variable frequency drive replacements, HVAC repairs, replacement of unit heaters and air compressors, ejector pit pump and booster pump replacements, exterior wall cladding and concrete repairs and replacement of failed truck‑bay speed doors. Staff also recommended replacing an in‑ground post‑style jack system with portable movable jack units that give greater flexibility for lifting large vehicles.
Other items
Staff listed LED retrofit work, electrical upgrades for expanded EV charging, generator panel upgrades to include critical circuits (for example, large garage doors), and EOC roller shutter repairs so emergency operations can seal windows in a critical incident. Public Works also recommended continued programmatic replacement of cast‑iron utility piping in the basement with PVC and a structural inspection of basement steel girders with a placeholder for any needed repairs.
Why it matters: the Public Works Center projects combine routine lifecycle replacement needs with sustainability opportunities. The solar project in particular is time‑sensitive because of federal incentive purchase deadlines and could materially reduce facility energy costs if design and metering choices align with village billing practices.
