The circular economy, including the reuse of building materials, is fast becoming a key component in the fight against carbon emissions. This involves designing to minimize waste and utilize materials that can be reused at the end of the building's life. On the opposing side, the reuse of materials from partially or wholly demolished buildings can also reduce waste and carbon emissions that would have resulted from using virgin materials. Sustainability purposes aside, the reuse of building materials has a centuries-old history, both for symbolic reasons and simply out of necessity.
President Ilham Aliyev has signed an order declaring 2026 the "Year of Urban Planning and Architecture" in the Republic of Azerbaijan. The decision establishes a national framework focused on urban planningpolicy, architectural culture, and sustainable development, aligning with Azerbaijan's preparations to host the 13th World Urban Forum (WUF13) in Baku in May 2026. According to the order, the designation aims to preserve Azerbaijan's centuries-old traditions while integrating contemporary approaches that respond to current social, environmental, and spatial challenges. The President's Administration will now prepare and submit a comprehensive action plan for the year within one month.
One month remains until the Opening Ceremony of the Olympic Winter Games Milano Cortina 2026, with competitions set to run from February 4 to 22, 2026. The Opening Ceremony will take place on February 6 at the Milano San Siro Olympic Stadium and will bring together approximately 2,900 athletes from around the world competing across 16 sports, with 116 gold medals to be awarded. The Olympic Winter Games return to Italy twenty years after Torino 2006 and seventy years after Cortina 1956. This edition, however, adopts a markedly different approach, proposing a shift away from the traditional high-cost, high-waste model toward adaptive reuse, renewable energy, and long-term regional development. The most geographically dispersed Winter Games in history plan to rely on 92% existing or temporary venues, build on regions with established tourism industries, avoid major environmental disruption, and implement circular design and recycling strategies, the results of which will become evident in the coming months. The Milano Cortina 2026 Winter Paralympics will follow, taking place from March 6 to 15, 2026.
Which materials have taken center stage in the architectural discourse of 2025? Which projects have rediscovered new construction practices and methods through material innovation? While the future of building materials still appears uncertain, year after year, experimentation and research continue to reveal diverse practices, initiatives, and efforts dedicated to understanding their value and responsibility within the built environment. From agricultural waste that reduces carbon footprints to recycled plastics given new life, and living materials that engage with emerging technologies while reconnecting with nature, 2025 has highlighted and strengthened the role of architects as mediators between materials, disciplines, knowledge, and interests from diverse origins.
