PROBLEM TO BE SOLVED: To solve a problem that, in a conventional greenhouse, it is difficult to regulate indoor temperature to a fluctuating temperature suitable for growth of a cultivation crop.SOLUTION: An environment controlling system for facility cultivation in which temperature is regulated as a setting value calculates a net photosynthesis speed at the setting value and a net photosynthesis speed at a smaller or larger value than the setting value using a photosynthesis model for calculating the net photosynthesis speed with a plurality of parameters including the temperature and newly updates the setting value with the larger value in a case where the net photosynthesis speed based on the other values than that based on the setting value. An optimal cultivation environment is realized effectively using energy by accurately regulating the temperature which is important in environment parameters so as to follow the suitable growth temperature correspondingly fluctuating to change in exterior environment. |
