The energy efficiency of buildings is assessed on the base of thermal insulation properties that can help to save energy costs as well as environment. The wooden materials are widely used as they become significantly recyclable and nature-friendly. Their thermal insulation properties have to be known for construction purposes. The modern experimental methods for the Thermophysical measurements are highly desired in this field. The methodology for the experimental measurement setup has to be optimized and possible disturbing effects at measurements have to be taking into account. The first more sophisticated method is to include disturbing effect into the model or to use the second one by arrangement of the sample set geometry as close as possible to the ideal state. The pulse transient method is relatively fast in comparison with stationary methods. It is simple for experimental arrangement and reliable for large scale of materials. Measurement reliability in this paper was tested by increasing the heat pulse energy, as the estimated Thermophysical parameters have to be independent on used power. The data scattering found for all measurements was found below 2% for all Thermophysical parameters.

Abstract
The energy efficiency of buildings is assessed on the base of thermal insulation properties that can help to save energy costs as well as environment. The wooden materials are widely used as they become significantly recyclable and nature-friendly. Their thermal insulation properties have to be known for construction purposes. The modern experimental methods for the Thermophysical measurements are highly desired in this field. The methodology for the experimental measurement setup has to be optimized and possible disturbing effects at measurements have to be taking into account. The first more sophisticated method is to include disturbing effect into the model or to use the second one by arrangement of the sample set geometry as close as possible to the ideal state. The pulse transient method is relatively fast in comparison with stationary methods. It is simple for experimental arrangement and reliable for large scale of materials. Measurement reliability in this paper was tested by increasing the heat pulse energy, as the estimated Thermophysical parameters have to be independent on used power. The data scattering found for all measurements was found below 2% for all Thermophysical parameters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
