As extreme heat becomes the new normal for billions of people, the question of how we design and build is no longer academic - it's urgent.
This summer, Article 25 took that message to three major industry platforms, sharing two decades of frontline experience designing schools, hospitals and homes in some of the world's most climate-stressed environments.
In June, we joined a CPD-accredited webinar hosted by The Chartered Institute of Building (CIOB), chaired by Amanda Williams, CIOB's Head of Environmental Sustainability. The session walked a large, engaged audience through the core principles of passive design - orientation, shading, thermal mass, natural ventilation and daylighting - brought to life through projects in Niger, Tanzania and Ladakh. Our college project in Niger, built using locally sourced laterite stone and a ventilated double-roof system, recorded internal temperatures up to eight degrees cooler than outside, with no mechanical cooling at all.
We carried that same message to the Sustainable Buildings & Construction Summit 2026 in Lausanne, co-organised by EPFL's Centre for Worldwide Sustainable Construction and UN Environment Programme's Global Alliance for Buildings and Construction (GlobalABC), where we joined a workshop on disaster-resilient construction drawing on our Dominica Housing Recovery Project, and delivered an Innovation Spotlight on the Niger college scheme. And at the Stone & Surfaces Show, we took a closer look at the materials and methods behind that same project - showing how locally sourced, low-carbon materials can outperform imported cement-based construction on cost, comfort and character.
Across all three events, one thread ran through: as extreme heat reshapes where and how people can live safely, the answer isn't ever more mechanical cooling - it's smarter, climate-responsive design rooted in context, craft and centuries of vernacular knowledge.
With over 100 projects delivered in more than 35 countries, we're proud to share what we've learned, and we're looking forward to building on these partnerships and conversations in the seasons ahead.
