The paper presents the development of a method that determines building material and surface properties using relative simple and low-budget experiments, The method comprehends an optimal design of an experimental set up for smart determination of heat and moisture properties using both normal and inverse modeling techniques.

It is concluded that the suggested methodology of the inverse problem technique seems promising for estimating material properties but requires that: (1) All measurements errors must be known; (2) The (measured) signals itself should deliver enough input power into the system; (3) The simulated objective data should be sensitive enough for changes in material properties.
