Ally Bank presents Lewisville workplace overhaul to Farmers Branch sustainability committee

Ally Bank’s director of workplace sustainability, Eoin Fitzgerald, told the Farmers Branch Sustainability Committee on June 12 that a recent renovation of a 120,000‑square‑foot Lewisville property combines energy and operational measures designed to cut emissions and operating costs. Fitzgerald said the project replaced 27 old air‑conditioning units with a system he described as “25% more efficient” and converted the building’s gas heating to electric to pair with on‑site solar generation.

The renovation also included EV charging infrastructure and solar carports. Fitzgerald said conduits were run for 10 chargers with capacity to service up to 20 vehicles and that engineers estimate the planned solar array will meet about 90% of the building’s annual energy needs. He described a contractor failure late in the install; the project team has re‑engaged subcontractors and expects the solar system to begin producing electricity around Nov. 1. Fitzgerald said the panels are expected to remain serviceable for 20 to 25 years.

On the financials, Fitzgerald said the solar capital cost was roughly $4,000,000 and that the Inflation Reduction Act’s investment tax credit and other incentives materially improved payback: “the solar company told us we would have a return … in seven years,” he said, but the company’s tax group estimated an accelerated payback of about 2.5 years after depreciation and tax incentives.

Fitzgerald also described a centralized waste and composting pilot from Ally’s Charlotte headquarters. He said removing individual workstation trash cans and installing central stations raised measured diversion rates in pilot floors substantially — giving examples that ranged from an initial 9% recycling rate on one control floor to as high as 64% after interventions on a different floor, and reporting an aggregate shift “from a 9% diversion rate to a 45% diversion rate” across tested areas. The pilot also reduced janitorial trips (the team estimated avoiding 38,000 single‑use plastic bags across three test floors) and diverted about two tonnes of material to compost, which went to a local compost company.

Fitzgerald said operations and education are critical to success. He described in‑house audits and a proposed ‘Oscar’ smart‑screen system (camera + display) to guide users at bins and reduce contamination. On batteries he said the team opted not to add battery storage for the solar array, planning instead to export excess generation to the grid and to upgrade the site transformer to handle peak export periods. “We’ll be selling it back to the grid,” Fitzgerald said, noting some uncertainty about whether recent HVAC electrification will change the projected 90% offset.

Committee members asked about leadership buy‑in and custodial costs; Fitzgerald said brand reputation and a data‑driven pilot helped secure funding and acceptance, and that janitorial contracts will be renegotiated to reflect operational savings. He encouraged local collaboration and offered to share lessons learned and contacts for tours and follow‑up questions.

The committee did not take action on the presentation; staff and members discussed follow‑up opportunities such as campus visits and community partnerships.
