For an overall evaluation of the use of artificial light in greenhouses, heat and electricity consumption, the greenhouse construction and the light conditions have to be regarded simultaneously.

The evaluation of control strategies for various artificial light systems was carried out by means of a modular simulation program. The results of the simulation led to the necessity of specific experimental investigations.

The energy consumption of artificial light systems varies very much in dependency upon the insulation of the system. The results of the simulation and the measurements show that the artificial lighting acts like a heating system and reduces the amount of heating energy in the same magnitude as the installed wattage.
