The present research proposes a preliminary investigation of the new hourly method for the assessment of building energy needs for heating and cooling introduced by the EN ISO 52016-1 standard. It was applied to a case study and compared with a fully detailed dynamic model (EnergyPlus). The comparison was performed considering two building operation modes: in a free-floating condition, the hourly differences between the indoor operative temperatures were analysed considering the different contributions to the heat balance; in an ideal heating and cooling system operation, the heating and cooling energy needs were compared on a monthly basis. The discrepancies between the calculation methods, both in the indoor operative temperature and in the thermal energy needs, were investigated and the causes of the deviations were identified.

Abstract

The present research proposes a preliminary investigation of the new hourly method for the assessment of building energy needs for heating and cooling introduced by the EN ISO 52016-1 standard. It was applied to a case study and compared with a fully detailed dynamic model (EnergyPlus). The comparison was performed considering two building operation modes: in a free-floating condition, the hourly differences between the indoor operative temperatures were analysed considering the different contributions to the heat balance; in an ideal heating and cooling system operation, the heating and cooling energy needs were compared on a monthly basis. The discrepancies between the calculation methods, both in the indoor operative temperature and in the thermal energy needs, were investigated and the causes of the deviations were identified.
