When an energy balance is calculated in accordance with DIN V 18599, an integrative approach is taken, i.e. the building carcass and the utilization of the buildings technical installationsand equipment are evaluated together,taking the interaction of these factors into consideration.In order to provide a clearer structure, the DIN V 18599 series of preliminarystandards is divided into several parts, each having a particular focus. The DIN V 18599 series of preliminary standards providesa method of calculating the overall energy balance of buildings. The described algorithm is applicable to the calculation of energy balances for:- residential buildings and non-residential buildings;- planned or new building constructionand existing buildings.The procedure for calculating the balances is suitable for:- balancing the energy demands of buildings with partiallypre-determined boundary conditions;- balancing the energy demand of buildings with freely-selectable boundary conditions from the general engineeringaspect, e. g. with the objectiveof achieving a good comparison between energy demand and energy consumption (demand/consumption comparison).The balance calculations take into account the energy demand and consumption for:- heating,- ventilation,- regulation and control of the indoor climate conditions (including cooling and humidification),- heating the domestic hot-water supply, and- lighting of buildings, including the additional electric power consumption(auxiliary energy) which is directly related to the energy supply. The method of the DIN V 18599 is fed into the EPBD CEN standards.
