Two fuzzy logic controllers, where expert knowledge of the agriculturists and growersis emdedded, are developed. These controllers consist of a fuzzy P (Proportional) and a PD (Proportional-Derivative). The monitored variables are the greenhouse’s indoor illuminance, indoor temperature, relative humidity, CO2 concentration and the outside temperature. Moreover, necessary meteorological data are collected from a meteorological mast. The actuators of the system are the heating units, motor-controlled windows, motor controlled shading curtains, artificial lighting, CO2 enrichment bottles and water fogging valves. The fuzzy controllers’ aim is to obtain the best possible indoor conditions for any cultivation (set-points). The platform used is the LonWorks™ platform. The controllers were prototyped in Matlab™ and were interconnected into the system as a separate node by taking the advantages of the LonWorks protocol. The system is installed in a greenhouse located in the Mediterranean Agronomic Institute of Chania, Greece (MAICh). http://creativecommons.org/licenses/by-nc-nd/4.0/ International Workshop on Energy Performance and Environmental Quality of BuildingsProccedings of the International Workshop on Energy Performance and Environmental Quality of Buildings Saridakis Georgios Σαριδακης Γεωργιος Kolokotsa Dionysia Κολοκοτσα Διονυσια Dolianitis S.
