Fuzzy logic assessment of thermal performance of concrete wall

This paper presents a fuzzy logic model for prediction of the U-value which considers outside temperature, outside relative humidity and elevation. The fuzzy logic model uses the Takagi Sugeno inferencing and was derived and tested on data available in literature for the Czech Republic. The model shows good agreement with the reference data obtained with a simple estimation tool also available in literature. The presented fuzzy logic model was tested for application and can be used for prediction of the U-value for the weather conditions in the Czech Republic, both in lowland and highland, and also anywhere in between. This approach proved promising for further development.
