Simulazione Dinamica di un Tetto Verde: Modello Matematico ed Esempio Applicativo

The present work refers to a mathematical model developed by the authors to quantitatively evaluate the unsteady thermal behavior of a green roof (that's with earthly layer). The contribution given by atmospheric precipitation has been kept into consideration when evaluating energy transmission and the associate advantage obtained when using this technology. In this work, the physical problem and the mathematical model implemented are shortly presented in order to explain the theoretical basis on which the thermal behavior of a specific covering (realized using a few layers) has been developed. In this work, physical problem and mathematical model are shortly treated to value thermal behavior of a covering (realized in more layers) and to measure all its consumed energy ; the second presents a model application to a real cas. The total energy consumption has been also calculated and an application to a real case of the full model is presented in the second part of the article. The project, worked out inside the Rete di Punti Energia and developed by Cremona Agency, takes as reference the characteristics of the Daku Technology Green Roof.
