The effect of dynamic primary energy factors on building energy performance

In the context of increasing environmental awareness, specific methodologies have been proposed for the definition, modelling and assessment of the buildings' energy performance. These Building Energy Assessment Methods (BEAMs) are still far from accurate, when applied on actual individual buildings. New detailed data allows to further optimize the BEAM. This paper presents a preliminary study on the influence of primary conversion factors, applied to two different calculation methods: one with an hourly time interval and one with a monthly time interval. The added value of hourly data is evaluated and the two methods, provided by the new ISO 52000 standard series, are tested. The total energy needs for space heating for both methods coincide quite well. For poorly insulated buildings the monthly calculation method showed higher results, compared to the monthly calculation method. For the well insulated buildings, the opposite became clear. The added value of hourly data on Primary Energy conversion Factors (PEFs), proved to be minimal
