The set of Energy Performance of Buildings (EPB) standards has been published in summer 2017. For the calculation of the energy performance the overarching EPB standard (EN ISO 52000-1) lists different options for the time interval (hourly, monthly, seasonal, yearly and bin). This article provides some background information why an hourly time interval is recommended.

Previous series of articles (REHVA 2015/1, REHVA 2016/3 and REHVA 2016/6) introduced the new set of international (CEN, CEN ISO) standards for the assessment of the overall energy performance of buildings (EPB).
The strongest interest is in those EPB standards that are ‘collectively’ needed to calculate the overall energy performance, either for existing buildings, for new buildings or for new building designs.
