In the sprawling landscape of post-war architecture, a significant yet often overlooked subset of buildings is quietly crumbling, and with them, a piece of our industrial and technological history. These are the prefabricated buildings, the concrete and steel testaments to a time of rapid innovation and reconstruction. Angelo Bertolazzi, a leading voice in the preservation of these structures, has shed light on the urgent need to safeguard this deteriorating heritage in his recent article published in the journal Tema, which translates to “Theme” in English.
Bertolazzi, whose affiliation is not specified, argues that these buildings, born out of the necessity and ingenuity of the post-war era, are a crucial part of our 20th-century architectural and technological legacy. They are, as Bertolazzi puts it, “the product of the large-scale pervasive effects of the technological progress of the 20th century.” Yet, despite their historical significance, they are often neglected, their demolition seen as a solution to their aging and poor public image.
The energy sector, in particular, has a stake in this conversation. Many of these prefabricated buildings are energy-inefficient, their outdated designs and materials consuming more power than their modern counterparts. However, rather than seeing this as a reason for demolition, Bertolazzi suggests that it could be an opportunity for retrofitting and renovation. By updating these buildings with modern energy-efficient technologies, we could not only preserve a piece of history but also contribute to a more sustainable future.
The commercial impacts of this approach could be significant. The energy sector could see a boost in demand for retrofitting services, while the construction industry could benefit from the increased need for skilled labor. Moreover, the preservation of these buildings could stimulate local economies, creating jobs and attracting tourists interested in architectural history.
However, Bertolazzi acknowledges that there are challenges to overcome. The negative public perception of these buildings is a significant hurdle, as is the lack of protection and preservation efforts. But he believes that by reframing these buildings as a valuable part of our heritage, we can change this narrative.
The article in Tema outlines several matters of fact and open issues that need to be addressed to achieve this reframing. These include the need for more research into the historical and technological significance of these buildings, the development of preservation guidelines, and the promotion of public awareness and appreciation.
As Bertolazzi notes, “The heritage of prefabricated buildings is outlined in Theme 2, ‘Accelerated scientific and technological development’.” By embracing this theme, we can ensure that these buildings are not just remembered as relics of a bygone era, but as a testament to our ability to innovate, adapt, and preserve.
The future of these buildings is not yet written. But with the insights provided by Bertolazzi and others like him, we have the opportunity to shape a future where our industrial and technological heritage is not just preserved, but celebrated. The energy sector, with its focus on innovation and sustainability, could play a pivotal role in this endeavor. After all, as Bertolazzi reminds us, “the ongoing and extended deterioration phenomena” of these buildings is not just a matter of preservation, but a matter of progress.
