A bright jewel shines in Piazza Madonna di Loreto in Rome

Enrico Realacci Architectures as Architects

A transparent cover that has as primary purpose to protect the archaeological site but also and just as important, to fill the void created by the excavation; "heal" the ground. Digging, exploring our roots to establish our unbreakable bond with the place, with the earth, the rock, our history. And then cover, protect, close the wound, through the construction of a "limen" - the transparent cover - that will allow us to think of both an inside and outside, a before and after. And to paraphrase Wittgenstein the ability to explore them both. The project takes all of this into account and has produced a cover that, while communicating with the elliptical shapes and concave-convex arrangement of the twentieth century, becomes an element of rehabilitation for Piazza Madonna di Loreto. The primary objective of the project is, undoubtedly, to preserve the archaeological remains avoiding any form of decay. At the same time to ensure the view of the structure from the outside through large transparent surfaces. The design of the cover, thanks to advanced technical solutions, has taken into account these requirements by eliminating undesirable effects due to the transparency of the cover: alterations in the microclimate, condensation, greenhouse effect. To reach this result we have chosen to use an innovative material specially calibrated to respond selectively to the different light frequencies while maintaining a full transparency. It is a special PMMA Poured (polymethylmethacrylate), already successfully tested on roofs of large archaeological works not only for its transparency and durability, but also for its lightness and strength. Associated with the PMMA solution is the choice of the aluminum alloy for the supporting structures. Lightness, stability over time, high mechanical strength, low maintenance, total reversibility, aesthetic quality, make the aluminum alloy the ideal solution in environments subject to corrosion and oxidation, if you want to avoid an unobtrusive maintenance (such as periodic painting). The morphological concept of the cover - two drops of water that come together on the floor - beyond this organic reference, corresponds to a precise reading of the context reflecting both the visual axis of the surface and the spatial coordinates of the archaeological plan. Approximately 200 LED projectors, perfectly integrated in the structure and managed by software, creates dynamic lighting accents that highlight, in predetermined sequences, the significant aspects of the archaeological complex. The cover becomes a bright chest that catches your attention inviting you to approach and look. At the base of the roof covering, near the ground, the transparent methacrylate then gives way to photovoltaic glass. About 80 square meters of glass panels will produce about 13,000 kWh / year, covering the entire energy needs of the structure. In conclusion: the roof covering will be more transparent and lighter than glass; it will be able to selectively block some light frequencies that most favour photosynthesis; it will have a good transparency to infrared rays so as to limit the greenhouse effect; it will produce all the energy required to operate the archaeological site.
