Green roofs for built environment recovery: technological transitions
In 2012, the Laboratory of Recovery and Maintenance at the University of Naples Federico II starts an applied research with the Institute for Composite and Biomedical Materials – IMCB – National Research Council of Italy – CNR, of Naples. The aim is to explore the potential of a patented hybrid foam, Hypucem, as a green technology for the recovery of flat roofs in reinforced concrete buildings. Two green extensive prototypes are developed and tested to provide an adequate response to the problem of residential buildings. The difference between them is in the mode of greening: sowing before or after the on-site assembly, with overlapping layers of green, in the first case, and their integration into special pockets formed inside the panel, in the second. Laboratory tests verify the germination and growth dynamics for a closed-cell polyurethane-concrete foam and for open-cell polyurethane-soil specimens. Trials are carried out in a residential neighborhood realized after Second World War. During six months, the benefits to buildings' performances, in both solutions, are monitored, highlighting the importance of roofs dimensions and accessibility. With a greater ease of installation and inspection, the open-cell polyurethane foam solution, accommodating transplanted vegetation, results more suitable for a direct involvement of users in ordinary maintenance. This attitude is fundamental in order to prevent any decrease in roofs thermal resistance due to the lowering of the green layers performances.
