Smart City Expo World Congress will occupy Fira de Barcelona’s Gran Via halls from Nov. 3 to 5 with a sharper brief than in past years. Organizers want the 2026 edition to move past concept decks and toward projects that cities can measure. The theme is “Urban Solutions, Real Impact.” Housing sits at the center of that claim.
The congress is built for scale. Fira de Barcelona is planning for 1,000 participating cities, more than 25,000 attendees, over 1,000 exhibitors and about 600 speakers. Those numbers matter because the audience is not only mayors and vendors. It also includes utilities, housing agencies, mobility operators, port authorities and the technology firms that now sit inside city contracts.
Seven program tracks will organize the debate: Enabling Technologies, Energy and Environment, Mobility, Governance and Economy, Living and Inclusion, Infrastructure and Building, and Blue Economy. Taken together, they cover the stack that cities actually buy: digital systems, power, transport, regulation, social services, buildings and waterfront industry. Artificial intelligence, green energy and social equity are expected to cut across those rooms rather than sit in a single pavilion.
Housing is the new piece. SCEWC will host the first HOWS Barcelona, a housing world summit on urban planning and land policy, housing regulation, social and affordable housing, and building renovation and reuse. The organizers present that agenda as a response to a problem most large cities now share: not enough homes at prices residents can pay, aging stock that is expensive to heat and cool, and planning rules that cannot keep up with demand. HOWS is meant to treat housing as infrastructure, not only as a social-policy sidebar.
The speaker list mixes futurists, technology officials and inclusion advocates. Nikolas Badminton, chief futurist at Futurist.com, is scheduled to talk about long-range city planning and scenario work. Ayumi Moore Aoki, founder of Women in Tech Global, will address diversity and inclusive leadership in urban innovation. The program also includes Bibiana Aido of UN Women, Bilel Jamoussi of the International Telecommunication Union and Chiara Corazza of the Women’s Economic Forum. The mix signals that Fira wants the congress to cover who gets to shape city technology, not only which sensors get installed.
On the floor, global technology companies will sit beside national and city pavilions. Confirmed names include Google, Microsoft, NVIDIA, Dell Technologies and Deutsche Telekom IoT. A new Terra50 showcase will present 50 urban sustainability projects that organizers describe as ready for wider use. The exhibition is designed as a buying hall as much as a conference. Cities come to compare vendors. Vendors come to find city pilots. The “real impact” theme is a warning to both sides that demonstrations without deployment will look thin this year.
SCEWC will not run alone. It is scheduled with Tomorrow.Mobility World Congress, Tomorrow.Blue Economy, Barcelona Deep Tech Summit and Barcelona Cybersecurity Congress. That cluster is Fira’s pitch that Barcelona in early November is a single stop for transport, ports and coastal industry, applied research and city-network security. For a mayor or procurement team, the calendar compresses several trips into one. For exhibitors, it concentrates buyers who used to be split across separate events.
The timing is deliberate. Cities are under pressure on housing costs, heat, congestion and digital public services at the same time. Many have already bought first-generation smart-city systems and are now asking what those systems changed. Energy and environment sessions will look at how buildings and grids absorb new demand. Mobility sessions will sit next door to the dedicated Tomorrow.Mobility congress. Living and inclusion tracks will test whether digital tools widen access or leave people out. Governance sessions will deal with the slower work of regulation, data rules and budgets.
Barcelona has used this congress for more than a decade to brand itself as a meeting point for urban technology. The 2026 edition tries to keep that role while narrowing the promise. Housing is the test case. If HOWS produces only speeches, the new summit will look like branding. If it produces comparisons of land policy, renovation finance and social-housing models that cities can take home, it will match the slogan on the banners.
Registration and program details run through Fira de Barcelona and the Smart City Expo World Congress site. The three-day meeting is now the main autumn gathering for city officials who have to turn technology budgets into housing, transport and climate results.
