So as to be able to evaluate the behavior of cold greenhouses during the night in Mediterranean area, a representative mathematical pattern of the nocturnal energetic balance of single plastic skin greenhouses is proposed. Such mathematical pattern allowed a forecasting analysis of the thermal level inside the greenhouse for short time intervals; the results obtained in this way were compared to the measured values of a small frame type greenhouse without any artificial energetic contribution.

Abstract
So as to be able to evaluate the behavior of cold greenhouses during the night in Mediterranean area, a representative mathematical pattern of the nocturnal energetic balance of single plastic skin greenhouses is proposed. Such mathematical pattern allowed a forecasting analysis of the thermal level inside the greenhouse for short time intervals; the results obtained in this way were compared to the measured values of a small frame type greenhouse without any artificial energetic contribution. A special attention was given to the elaboration of temperature data during the clear sky nights in the winter, whereby the thermal gradient inversion between inside and outside occurs.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
