Abstract
In order to calculate the losses of a greenhouse it is necessary to characterise the cladding material.
Usually, the cladding material is characterised by the level of its transparency in the infrared range.
Usually, the cladding material is characterised by the level of its transparency in the infrared range.
But, other considerations need to be taken in account, such as losses by convection, leaks, condensation, etc…
This paper presents a global method for the calculation "in situ" for an overall loss coefficient using external hot boxes, and its theorical value calculated by the mean of a software program, according to standards conditions.
