In an analysis of the results, by comparing the actual parameters, taking into account the condition of public buildings, it is necessary to evaluate the energy savings after implementation of energy saving measures. A complex comparative analysis of data processing methods is presented, on the basis of which an assessment of the changes in the process of application of energy saving measures for buildings, in its entirety, and in particular the energy projects in two Bulgarian cities, in view of their dynamics and future development.

When water stress occurs in cucumbers, it creates conditions for changes related to the color surface texture of their leaves. The purpose of this work is to search for relationships between data obtained from spectral characteristics and those from determining physiological indices of cucumbers. It is established that the separation of the different stages of the development of water stress in cucumbers does not depend on the choice of a method for reducing the amount of data of spectral characteristics, but on the used separation functions of discriminant analysis. When using linear separator functions, the total classification error reaches values above 10%, which makes the use of these functions inappropriate. The ability to predict physiological parameters of cucumbers by using reduced spectral data was evaluated. The results obtained are generally unsatisfactory. Further research is needed to make the methods and tools proposed in this paper suitable for use in practice.
