The dynamic model of EN ISO 52016-1 for the energy assessment of buildings compared to simplified and detailed simulation methods

The research investigates the new hourly method of the assessment of building energy needs for heating and cooling introduced by EN ISO 52016-1. It is compared against both the hourly model of EN ISO 13790 and a detailed dynamic simulation tool (EnergyPlus). The deviations between methods are discussed through a case study. The new method, if properly customized as regards input parameters, provides results close to the detailed simulation, as regards the energy need assessment. The work is aimed at contributing to the normative activity through the validation of the new calculation method, as to enhance its application for the building energy rating
