ABSTRACT In Colombia, flower production takes place in greenhouses of different types and geometric shapes, but with the com- mon feature of using natural ventilation for climate control. At present the knowledge on the climatic performance of these structures is scarce. The aim of this work was to eval- uate the thermal behavior of a greenhouse under day and night climate conditions. The evaluation made by compu- tational modeling used the computational fluid dynamics (CFD) approach applied to a greenhouse dedicated to the production of carnation (Dianthus caryophyllus) and ex- posed to the weather conditions of the Sabana de Bogotá (Colombia). This methodological approach allowed us to ob- tain the thermal distribution patterns inside the greenhouse, finding that for the meteorological conditions evaluated, the greenhouse generates inadequate thermal conditions for the development of the crop. The validation of the CFD model was carried out by comparing the results of the simulations and the temperatures recorded in the real prototype of the greenhouse, obtaining an adequate degree of adjustment between the simulated and measured values.
