Atlanta is using the 2026 World Cup to turn Underground Atlanta into a walkable, lowâcarbon district built on adaptive reuse, smart streets, and local business.
Most cities treat mega-events like the World Cup as a flashy twoâmonth sprint. Atlanta is quietly trying something harder â turning a global sports moment into a long-term, lowâcarbon reboot of its historic core.
Underground Atlanta, a fourâblock district thatâs been everything from a railroad hub to a 1980s mall, is being rebuilt again. This time, the focus isnât just nightlife and tourism. Itâs walkability, adaptive reuse, safer streets, and a downtown that actually works for residents after the last fan leaves MercedesâBenz Stadium.
This matters because green technology isnât just about solar panels and batteries. Itâs also about how we redesign streets, buildings, and districts so they consume less energy, rely less on cars, and support local economies. Atlantaâs World Cup preparations are a live case study in how smart cities can align big events with climate goals.
In this post, Iâll break down whatâs happening at Underground Atlanta, why itâs a smart sustainability move, and what other cities â and private developers â can learn from it.
How a 2026 World Cup Site Became a Testbed for Green Urban Design
Atlanta is using the World Cup as a deadline to make downtown more walkable, safer, and less carâdependent, especially around Underground Atlanta.
The district sits just steps from the Five Points rail station, which is already a huge advantage for any green redevelopment. Instead of building new structures or parking garages, the current owner, Shaneel Lalani, and design teams from Page (now part of Stantec) are focusing on:
- Pedestrianâonly streets on key blocks
- Adaptive reuse of historic buildings instead of demolition
- Dayâandânight activation so the area stays busy and safer
- Infrastructure that serves locals first, tourists second
Hereâs the thing about large events like the World Cup: they can supercharge bad planning just as easily as good planning. Cities can pour money into carâcentric highways and temporary venues that sit empty after the event. Atlanta is trying to flip that script by anchoring its upgrades in:
- Longâterm transit accessibility (Five Points as the front door)
- Lowâcarbon construction choices (reuse over rebuild)
- Public realm improvements that reduce reliance on private vehicles
From a green technology perspective, this isnât about one shiny product. Itâs a systems move â where design, policy, and tech all push in the same lowâcarbon direction.
PedestrianâFirst Streets as Climate Infrastructure
The fastest way to cut urban transport emissions is to make walking and transit the default, not the backup plan. Underground Atlanta is being redesigned around that idea.
Two blocks of Upper Alabama Street are already pedestrianâonly, with a portion of Pryor Street set to follow. The new public realm design threads a tricky needle:
- Wide pathways that can handle food trucks, maintenance, and emergency vehicles
- Physical barriers and layout that prevent highâspeed vehicle attacks
- Safer, greener streetscapes with better lighting and urban greenery
This isnât just about comfort. It has direct climate and health impacts:
- Fewer private vehicles in the core mean lower local emissions and pollution.
- Shaded, wellâlit streets make walking feel safer and more viable yearâround.
- Clear wayfinding â especially for international visitors â helps shift people from rideâhailing to transit + walking.
Where green tech fits into pedestrian zones
If youâre planning or investing in similar districts, thereâs a layer of smart city technology that can quietly make this work:
- Adaptive LED street lighting that dims when streets are empty and brightens as foot traffic increases.
- Sensorâbased crowd analytics to monitor how people actually use streets and plazas, so you can refine layouts instead of guessing.
- Realâtime wayfinding via apps and digital kiosks, guiding visitors from stadiums and stations along the safest, most vibrant walking routes.
The reality? When you combine carâfree streets with smart lighting, data, and clear wayfinding, youâre not just creating a nicer experience. Youâre building climate infrastructure â streets that quietly push thousands of daily trips away from cars.
Adaptive Reuse: The Greenest Building Is the One You Already Have
The most climateâfriendly construction strategy isnât a futuristic material. Itâs not demolishing what already works.
Underground Atlantaâs new phase leans hard into adaptive reuse. Many buildings will be retrofitted rather than replaced, keeping what Phuong Nguyen from Page calls the districtâs âgrittyâ authenticity while opening the doors to new uses.
One standout example: the Antebellumâera Macon & Western Railway building at Pryor and Upper Alabama. Instead of tearing it down, the team is:
- Converting it into a 7,000âsquareâfoot âmicroâ food hall
- Prioritizing local restaurant startups and affordable lunch options
- Keeping the historic shell, character, and much of the embedded carbon
From a green technology perspective, adaptive reuse is a massive win:
- Reusing the structure can cut embodied carbon by 50â75% compared with new construction, depending on how much is preserved.
- Retrofitting allows integration of modern HVAC controls, highâefficiency lighting, and smart meters without the emissions cost of a full rebuild.
- âLight touchâ upgrades keep construction waste and material transport low.
Practical moves for greener adaptive reuse
If youâre involved in similar projects, there are a few highâimpact choices that pair design and tech:
- Smart building controls: Layer in building management systems that optimize HVAC, lighting, and plug loads based on occupancy.
- Envelope upgrades from the inside: Use interior insulation, air sealing, and highâperformance glazing where possible to respect facades while cutting energy use.
- Subâmetering for tenants: Give small businesses live visibility into their own energy consumption; this alone can reduce use by 10â20%.
Iâm biased here, but I think cities should actively reward this kind of work. Every adaptive reuse project is a quiet climate policy: less steel, less concrete, less waste, and a faster path to netâzero buildings.
Local Business, 24/7 Activity, and the Energy Footprint of a District
Most people donât think of local business strategy as part of green technology. They should. A districtâs energy footprint isnât only about building systems â itâs about how often those buildings sit dark and empty.
Lalaniâs team has already filled the underground level with art galleries and music venues hosting more than 700 shows a year. That took a dead mall and turned it into a nightlife engine. The next step is pushing that vitality up to the street level.
Thatâs where:
- The micro food hall
- Affordable commercial spaces
- Safer, greener streetscapes
âŠall work together. A district thatâs busy day and night:
- Uses its existing infrastructure more efficiently (transit, lighting, utilities)
- Feels safer, which pulls even more residents and visitors out of cars
- Supports shorter, local trips rather than long commutes to farâflung malls or entertainment districts
How smart systems keep a lively district efficient
A highâactivity area can still be energyâefficient if the tech is configured intelligently. For example:
- Dynamic HVAC scheduling tied to event calendars and occupancy sensors, so energy ramps up only when crowds actually arrive.
- Smart lighting zones where plazas, alleys, and facades are grouped and controlled based on realâtime use.
- Shared energy infrastructure â think district cooling, rooftop solar shared across tenants, or battery storage to smooth evening peaks.
Done right, a dense, mixedâuse urban district can have lower perâcapita emissions than spreadâout neighborhoods, even if it looks busier and brighter. The key is using technology to match energy use with real demand â and retiring the default setting of âeverything fully on, all the time.â
What Other Cities Can Learn Before Their Next MegaâEvent
The World Cup is a forcing function. Atlanta doesnât have the luxury of a 10âyear master plan; 2026 is right around the corner. That kind of pressure can be a gift if leaders focus on the right things.
Hereâs the approach Iâd copy if youâre planning for a major sport or cultural event:
1. Start with transit and walking, not parking
- Make the primary arrival experience carâfree: rail station + safe, vibrant walking routes.
- Use universal wayfinding (clear signage, maps, digital guidance) so visitors arenât forced into rideâhailing out of confusion.
2. Lock in adaptive reuse as the default
- Set a policy or internal standard that favors reuse of existing structures for fan zones, food halls, and hospitality.
- Pair design teams with energy and carbon consultants early so sustainability isnât bolted on later.
3. Design streets for people first, security second, cars last
- Turn key corridors into permanent pedestrian or lowâcar streets, not just âfan festival zonesâ that revert to traffic.
- Integrate vehicleâmitigation design (bollards, planters, chicanes) into the architecture, not as lastâminute barriers.
4. Use tech to make the green option the easy option
- Realâtime routing to transit, bike share, and walking paths.
- Smart lighting and energy management so the public realm feels safe and welcoming without wasting power.
If your city or company is serious about green technology, megaâevents shouldnât be exceptions to your climate strategy. They should be accelerators.
Turning ShortâTerm Attention Into LongâTerm Green Value
Underground Atlanta shows what happens when a historic site, a looming World Cup, and a growing climate agenda intersect. The districtâs transformation isnât perfect, but itâs pointed in the right direction:
- Pedestrianâonly streets that support lowerâcarbon mobility
- Adaptive reuse that slashes embodied carbon while preserving character
- Smart, smallâscale spaces for local business instead of generic bigâbox retail
- A strategy that thinks beyond 2026 and aims to bring residents back downtown
For our Green Technology series, this project is a reminder that the most impactful climate tech often looks like city design. It shows up as a closed street, a reused brick wall, a micro food hall in a railway building, or wayfinding signs guiding fans from a stadium to a transit hub.
If youâre a city leader, developer, or planner looking at your own âWorld Cup momentâ â whether thatâs a tournament, major festival, or just a surge in growth â this is the question to ask:
How can this surge in attention help you build the lowâcarbon, livable district youâll still be proud of in 2040?
If youâre ready to translate that question into a roadmap â from adaptive reuse strategies to smart district energy and pedestrianâfirst design â now is the time to start, not six months before kickoff.
