AEC Hackathon 2027 @ BLOXHUB is a three-day event in Copenhagen, Denmark, focused on applying technology and AI to the challenge of building CO₂-neutral, thriving cities. It is scheduled for 5–7 March 2027 at BLOXHUB, bringing together people who design, build, code and plan the built environment.1
The event’s purpose is practical collaboration: participants work on challenges drawn from industry partners’ current operations, including decarbonisation, biodiversity, data, delivery and trust. The organisers frame the weekend as a chance to test ideas against real working conditions, rather than simply discuss change.1
Teams form around shared problems and develop early-stage solutions such as tools, workflows, methods, prototypes or concepts. Mentors and partners support the work, with an emphasis on whether an idea could be useful in a project, organisation or value chain.1 The page says previous projects have sometimes continued after the event through funding, products or new collaborations, though it does not suggest that every project does so.1
The intended audience spans the built-environment and technology fields. BLOXHUB reports that AEC Hackathon events typically draw 100–150 people, including engineers, architects, computer scientists, BIM developers, design thinkers, anthropologists and technology enthusiasts.1 The format reflects the wider AEC Hackathon model, created in 2013 to connect people working on the built environment with technology developers and designers; events have taken place in cities including Berlin, Shanghai and Paris.13
Earlier media coverage of the broader AEC Hackathon has described it as a grassroots, cross-disciplinary gathering where teams work over a weekend on industry problems, with technology professionals and built-environment practitioners collaborating on possible solutions.24 Those reports concern earlier editions, not the 2027 Copenhagen event.
