The thermal transmittance of vertical opaque building envelope plays a key role in the
evaluation of thermal performance of residential buildings. This parameter is mostly determined
by standardized procedure, which often generates values that differ from those obtained in real
conditions. More accurate methods are based on in-situ monitoring of heat fluxes, however,
those methods are often expensive or time-consuming. The proposed project is aimed at
formulation of a computational fuzzy model for prediction of thermal parameters of residential
building envelopes in real conditions. At model formulation, the results of experimental analysis
are used. Such an analysis involves determination of basic physical, thermal and hygric
parameters of selected materials. Validation of the model is done on the basis of heat flux
monitoring in selected building envelopes exposed to various climatic loads. The validated
model is then used for generation of knowledge base allowing for prediction of thermal
properties of residential building envelopes by application of fuzzy decision-making.
