Controls for the climate in a space such as a building such as greenhouse, barn, office and house or such as a vehicle such as car , ship and aircraft. An organism therein forms part of the control system for the climate in the space, and the controls comprise the at least co-controlling of the temperature of this organism. Use is here at made of at the level of the organism supplied, unsaturated, in dependence of directing by the controls conditioned air. The controls depart from a temperature registration of the organism and climate registration (temperature, air humidity and speed) in the space at two respective height levels. With an at a first level established relation between climate parameters and organism temperature an expectation in organism temperature is determined on the basis of a change in the climate parameters at the second level. By determination or establishment of difference between desired and measured plant temperature and determination or establishment of heat flow, conditioned air can be supplied better and more direct.
