diplomsko delo

Abstract

V diplomski nalogi je predstavljen preračun toplotnih izgub hiše z uporabo standarda SIST EN 12831 in s programskim orodjem Integra CAD Suite za enostanovanjsko hišo energetskega razreda A2. Izdelani so izračuni toplotnih prehodnosti posameznih gradbenih elementov; predstavljeni so tudi ogrevalni in prezračevalni sistem hiše ter energetska izkaznica objekta. Iz toplotnih izgub smo izračunali letno porabo energije za ogrevanje obeh metod in rezultate primerjali z dejansko letno porabo ter s porabo iz energetske izkaznice. Transmisijske toplotne izgube se ujemajo odlično; na 1 %, medtem ko se prezračevalne izgube ujemajo na 16 %. Odstopanja se pojavijo predvsem zaradi razlike v metodologiji izračunavanja.

Secondary title:	Heat loss calculation of a living house and description of heating and ventilation system
Secondary abstract:	The thesis represents the calculation of heat losses using the standard SIST EN 12831 and the software tool Integra CAD Suite for an existing house of energy class A2. Calculations of thermal transmittance of individual building elements have also been made. The heating and ventilation system of the house and the energy certificate of the house are also presented. We used heat losses to calculate the annual energy consumption for heating of both methods and compared the results with the actual annual consumption and with the consumption from the energy certificate. Transmission heat losses match almost perfectly. The deviation is only 1 % while ventilation losses have a deviation of 16 %. Deviations occur mainly due to differences in the calculation methodology.
