Nestled in a commercial district dominated by surface parking, Gulf Coast Bank’s Elmwood branch is designed to produce more energy than it consumes, setting a new benchmark for off-grid-capable banking facilities in the Gulf South. This achievement is made possible by an interconnected system of technologies: a 40 kW solar rooftop array, 40 kWh SolarEdge batteries, and SPAN smart electrical panels, each intentionally selected for its performance advantages.
The branch becomes a hub for people—not just cars.
The SolarEdge batteries include “Weather Guard,” a predictive system that responds to approaching storms by switching the micro-grid into backup mode and maintaining a 100% charge, ensuring resilience during outages. The SPAN Smart Panels extend this resilience by prioritizing circuits: at 50% charge, nonessential breakers shut off, followed by further tiered reductions at 30%. This staged response allows the branch to operate longer until batteries are recharged by sunlight.
These advanced systems are only effective within a highly efficient building. The branch has an airtight, well-insulated envelope, LED lighting, energy-efficient appliances, and a geothermal HVAC system. Together, these measures dramatically reduce energy demand and lengthen off-grid operation.
The geothermal HVAC system further enhances efficiency by tapping into the earth’s stable below-ground temperature—about 65°F in New Orleans—as a natural heat sink. Sixteen 300-foot-deep geothermal wells circulate water through a continuous loop connected to ground-source heat pump units in the mechanical room. In summer, the system draws warm water already used by the ground-source heat pump units, which is naturally cooled as it passes through the geothermal loop and wells before returning to the heat pumps. This passive exchange reduces the work required to reach the desired indoor temperature, lowering energy use without sacrificing comfort.
The design introduces a richly planted edge along the building facade—bringing texture, color, and seasonal variation to the pedestrian experience. Native species were selected for their beauty and ecological function, contributing to habitat creation and a more welcoming streetscape.
Emphasizing both environmental stewardship and architectural distinction, the building employs a predominantly wood construction system to minimize embodied carbon and maximize carbon sequestration with wooden structural elements and cellulose insulation enhancing its sustainability credentials. Expansive overhangs shade the structure from the intense southern sun, reducing cooling loads while maintaining a contemporary elliptical form.
The building massing and form is a reinterpretation of architecture in the era of commercial development for Elmwood’s growth in the 1970’s. The massing is both sculptural and functional, maximizing daylighting while ensuring an omnidirectional presence within the surrounding urban area.
Inside, the interiors reflect the warmth of the wood ceilings, which continue through to the exterior, connecting the commons areas to the exterior landscape and vice versa. Clean white walls balance refinement with durability when paired with polished concrete floors, reducing potential carbon usage by not requiring any additional finishing substances.
The interior material palette balances visual calm with brand identity. Clean white walls and polished concrete floors were chosen for their durability and minimalist aesthetic—allowing wood ceilings and daylight to take center stage. Gulf Coast Bank’s signature teal and orange branding is subtly woven throughout, adding recognition and vibrancy to the refined interior. Strategic use of the brand’s signature teal and orange injects warmth and vibrancy into key gathering zones.
The curved shape isn’t just eye-catching; it helps guide people through the space in a way that feels easy and intuitive.
Whether you’re pulling into the lot, walking into the lobby, or sitting inside, the soft arc naturally leads your view and your movement, creating a smooth, welcoming experience from every angle.
