The use of a simple simulation tool for energy analysis

The purpose of this paper is to present a new method to energy analysis. The method consist three different phases: in the first phase the target values of energy consumption are determined. In the second phase the potential differences between target and measured consumption are inspected by auditing the building. The effect of different energy saving measures are analysed in third phase. All these phases are assisted with a simulation tool. This tool uses effectively data base for generating input values for calculations. Minimum information need is the year of construction and type, location and volume of the building. During the audit the input values are checked and supplemented. The tool consist also semi-automatic procedures for fault diagnosis and energy saving measures. The calculation method itself is now quite simple and based on steady-state method.
