Energy efficiency of buildings - Calculation of the net, final and primary energy demand for heating, cooling, ventilation, domestic hot water and lighting - Part 1: General balancing procedures, terms and definitions, zoning and evaluation of energy sour
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 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 an overview of the procedures for calculating the energy need, delivered energy and
primary energy for heating, cooling, lighting and the domestic hot water supply of buildings. The central
balance equations are described in this part.
Furthermore, it explains the general terms which apply for all parts of the DIN V 18599 series. The general
balance calculation method is outlined together with separate information on calculations for residential
buildings and non-residential buildings. The procedure for defining zones of buildings is explained. In the
Annex, factors for assessing the environmental effects of the energy use (primary energy factors) are listed.
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 contain an illustration similar to Figure 2 as shown here and in which the respective
energy components dealt with are shown in colour.
