Comparison of the simplified methods of the ISO 13790 standard and detailed modelling programs in a regulatory context

Journal Article


Abstract


  • The CEN standards that support the European Energy Performance of Buildings Directive requirement for

    calculation of the energy consumption of buildings allow various methods to be used for the same calculation. The

    impact of using the different methods within the updated ISO 13790 standard for space heating and cooling energy

    calculations was examined with a parametric analysis of a common building specification. The impact was assessed

    by considering the energy band, which would be assigned for the building based on the calculation results. The

    standard describes three different methods that can be used for the calculations: a monthly quasi-steady state

    method, a simplified hourly method and detailed simulation. For most cases studied, differences in the building

    rating given by the various methods were a maximum of one band. More significant differences were noticed in some

    cases. Parameter values in the monthly method were determined, which would lead to improved matching.
