Abstract

The straight way to perform the targets of the Energy Efficiency Directive is the renovation of the existing buildings. Qualitative renovation begins by professional analysis of actual energy consumption and by choosing the packet of energy efficiency measures. The methodology for continual improvement and handy decision making can help to enhance the renovation process. This paper presents the concept of the model of sustainable management of building energy performance characteristics. The model is the algorithm for continual process for evaluation of current building construction operating and maintenance information, evaluation and prioritization of energy efficiency measures, the formation of their packets for suggestions for decision maker or for building administrator. In the presented model the five main criteria (energy efficiency, environmental impact, economical rationality, comfort and duration under Life cycle point of view) are used as criteria reflecting sustainable attitude. Sequential prioritization and distribution decision tree is constructed for distribution of energy efficiency measures to the basic and additional energy efficiency measures. The case study illustrates the optimization of packets formation, and represents the systemized information output for decision maker or building administrator.
