Sažetak
This paper presents comparison of calculations performed by a numerical dynamic simulations software IDA ICE and those according to EN ISO 13790, widely used for determining building energy need (as implemented in Croatian national Algorithms used for energy certification, as a modification of simple hourly method from EN ISO 13790) performed by “Energetski certifikator” software. A simple model of a nearly-zero energy building was created and all heat gains and set- points that could lead to a mismatch in initial or boundary conditions were eliminated. The impact of those on the annual heating and cooling energy need was examined by adding and removing every single one of them. Numerical dynamic simulations were set up to match the boundary conditions of simple hourly method. Such an approach enables evaluation of the differences in annual heating and cooling energy need and definition of their origin. The comparison of results has shown that in most cases, annual energy need for heating and cooling calculated using numerical dynamic simulations software differs from that calculated using EN ISO 13790. Among the others, more detailed heat accumulation model of building’s envelope in IDA ICE software was marked as the main reason. Fact that solar heat gains seem to be underestimated by EN ISO 13790 and differences in heat transfer towards ground contribute to results as well.
