Abstract

The different possible positions for the roof and sidewalls of retractable roof greenhouses allow them to behave either as greenhouses, shadehouses or wind barriers.
Radiation and wind control must be part of the control strategy along air temperature which proves to be a poor method of control as it is the case currently.
Globe temperature is proposed as a viable controller for retractable roof greenhouses in arid regions, for its ability to integrate in one simple data point temperature, radiation, and wind speed.
With the use of two globe thermometers it is possible to merge the data between outdoors and indoors to create an improved environment for vegetable cultivation while maximizing light exposure for the plants.
