Postojeća arhitektura regenerira budućnost

Existing architecture offers a viable path toward urban regeneration, challenging decades of assumptions that equated progress with demolition. In an era focused on innovation, the prevailing model of clearing space for new glass and steel structures faces scrutiny against the backdrop of climate urgency and cultural erosion. The emerging premise suggests that the most sustainable building is one already standing. Preserving, rehabilitating, and activating architectural heritage have become central strategies for addressing environmental, social, and cultural challenges. This approach is not merely nostalgic but serves as a strategic design tool. It involves recognizing existing values, deciding what to maintain versus what to transform, and extending the useful life of buildings while adapting them to contemporary needs through continued uses or new programs. Scientific data contradicts the notion that new projects are inherently efficient. The United Nations Environment Programme reports that the building and construction sector accounts for approximately 37 percent of global carbon dioxide emissions and nearly 50 percent of worldwide material extraction. Demolishing existing structures discards thousands of tons of materials that have already incurred their environmental cost. Research supported by the National Trust for Historic Preservation indicates that a new high-efficiency energy building may take between ten and eighty years to offset its own construction carbon footprint compared to intelligent rehabilitation. Additionally, construction and demolition waste represents 30 to 40 percent of global solid urban waste, straining landfills and undermining circular economy principles. Industrial architecture provides a particularly vibrant example of this paradigm shift. Former factories and warehouses serve as ideal supports for new interventions. These structures allow for experiments in balancing permanence with transformation, combining memory with contemporary design. Adapting such spaces for mixed uses, including housing, cultural centers, studios, or commercial areas, revitalizes established neighborhoods without expanding the urban footprint artificially. This avoids the economic and ecological costs of disorderly peripheral growth. The goal is not to mummify the past or engage in empty historicism, but to critically rewrite history by maintaining continuity in labor memory and collective identity while integrating technology. In Buenos Aires, specific efforts align with these broader trends. A bill introduced in the Chamber of Deputies seeks to declare the Zivals record store building of National Historical Interest. The measure aims to prevent the demolition of the iconic Porteño establishment, which faces removal due to the construction of Line F of the subway system. The proposal highlights the tension between infrastructure development and heritage preservation. Supporters argue that saving the structure preserves a piece of local cultural identity. On Saturday, a symbolic hug around the building is planned to draw attention to the cause. The legislative process will determine whether the site retains its protected status amidst the ongoing subway expansion plans. The debate reflects wider discussions about how cities manage their built environment in response to both infrastructural demands and environmental imperatives.
