Scope

The DIN V 18599 series of prestandards provides a methodology for 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 construction and existing buildings. The procedure for calculating the balances is suitable for: balancing the energy use of buildings with partially pre-determined boundary conditions; balancing the energy use of buildings with freely-selectable boundary conditions from the general engineering aspect, e.g. with the objective of achieving a good comparison between calculated and measured energy use ratings. The balance calculations take into account the energy use for: heating, ventilation, air conditioning (including cooling and humidification), heating the domestic hot water supply, and lighting of buildings, including the additional electric power input (auxiliary energy) which is directly related to the energy supply. This document provides a method for calculations relating to the domestic hot water system of buildings. This document describes the energy use of domestic hot water systems with their subsystems (control and emission, distribution, storage and generation). For this purpose, both the thermal losses and the auxiliary energy of the individual subsystems are determined and, provided these occur within the heated zone, are made available for the ensuing calculations described in DIN V 18599-1 and DIN V 18599-2. Information is given on the possible influence of space heating according to DIN V 18599-5. Other systems, (such as ventilation of residential buildings (see DIN V 18599-6)) that can make demands on or supply certain subsystems, can accordingly be taken into account and analysed, with DIN V 18599-1 acting as the link between the Parts. It is also possible to calculate the energy balances of several building zones in which there are several units to be balanced. Figure 2 shows the scope of the present document as a diagram. For the reader's orientation, all other parts of the DIN 18599 series of prestandards contain an illustration similar to Figure 2 as shown here, and in which the respective energy components dealt with are shown in colour. The energy need values calculated using this procedure cannot be used to size individual components. Systems not covered by this document shall be assessed by analogy with this document while taking account of the physics specific to the individual systems.
