Abstract Bio-economic models can be used as base for decision support systems. In protected cultivations, the glasshouse climate is of major importance on the financial result, both by costs and by yield. In this paper, a mechanistic climate model is described in detail. This glasshouse climate model is repartioned into four submodels: radiation- and lightintensity, heat- and daily ventilation need, mean day- and 24 hours temperature and a gas consumption submodel. Variation in CO2-concentration and low temperatures, especially at night had a large influence on the productivity.
