Calculation of Solar Energy Use as a Part of Determination of the Energy Performance of Building

The paper presents an actual national methodology in Croatia for the calculation of used solar energy in solar systems. It is based on Directive on the energy performance of buildings (2010/31/EU) and EN 15316-4-3 standard. The method has been successfully used in the calculation and proposing measures for increase energy efficiency in buildings. This contributes to increase the share of renewable energy sources, and thus reduces the consumption of primary energy. This paper presents a comparison of the calculation performed according EN 15316-4-3 which is based on monthly values and detailed hourly calculation based on hourly meteorological data of the test reference year. Comparison of the data is given for domestic hot water solar system of a family house located in the Mediterranean coastal region.
