In a sustainable city development project in Flanders (Belgium), a district sports centre according to the PassiveHouse standard is planned. To evaluate the requirements of this standard, simplified calculation method for assessment of the annual heating and total primary energy use based on EN ISO 13790 is used. As these calculations are strongly affected by the boundary conditions, they can only offer representative results for evaluation of the performance level of the design if the boundary conditions are defined properly. Therefore, to reassure objective and unambiguous evaluation, a variety of parameters is defined specifically for district sports centres: indoor temperature, occupancy rate, ventilation rate, user profile, internal heat gains and sanitary hot water use. The paper gives an overview of these boundary conditions and amplifies the effects of these properties on the net energy demand for heating and cooling and total primary energy use for heating, ventilation, lighting and sanitary hot water production in a districts sports centre. Two levels of energy performance are distinguished: (1) reference case according to the Flemish EPBD requirements from 2014 and (2) Passive House standard. Moreover, the calculated end energy use for gas and electricity are compared to a database with measurements of 86 existing sports centres in Flanders (Belgium).
