Energy efficiency of buildings - Calculation of the net, final and primary energy demand for heating, cooling, ventilation, domestic hot water and lighting - Part 6: Final energy demand of ventilation systems and air heating systems for residential buildi
The DIN V 18599 series of prestandards provides a 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 constructions 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 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 describes a method of calculating the values for ventilation and air heating systems of
residential buildings.
This document describes the energy use of ventilation systems and air heating systems for residential
buildings in conjunction with individual subsystems (control and emission, distribution, storage and
generation). For this purpose, both the heat losses and the auxiliary energy of the individual subsystems are
determined and, provided that these occur within the heated zone, are made available for the subsequent
calculations described in DIN V 18599-1 and DIN V 18599-2.
It is also possible to determine the use of subsystems for heat delivery to DIN V 18599-5 and DIN V 18599-8
and vice-versa. In such cases, the initial output data are from DIN V 18599-1 and DIN V 18599-2, while the
boundary conditions are obtained from DIN V 18599-10. It is also possible to calculate the energy balances of
several building zones in which there are more than one 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 V 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.
