the Din V 18599 provides a
segregation of the overall building
into various zones, since diverse
areas within the building are used for
various purposes and these require
different conditioning. A zone includes
those rooms within a building that
demand similar parameters on
account of their use (temperature,
ventilation, illumination, internal
loads, daylight provision, technical
equipment) with similar framework
conditions. every zone has one of
33 programmed utilisation profiles
applied to it (e.g. office, hotel room,
kitchen, toilet, transit areas). the
energy demand for heating and
cooling must be defined separately
for each conditioned zone. Up to
a proportion of 3% of the overall
available floor area, living space may
be appropriately assigned to different
zones than those to which they should
be designated, as long as the internal
loads are not substantially different.
to simplify the calculation process it is
permissible to determine the annual
primary energy demand in accordance
with a single zone model for the
following types of building: schools,
kindergartens, office buildings, hotels
(without internal swimming pool),
pubs and commercial premises.
However, different framework
conditions must still be applied.
Main areas of use and passages must
account for at least one third of the
total area; the building must only be
equipped with a central system used
to provide DHw and central heating
and must not be cooled. illumination
must largely correspond to the
reference lighting technology.
the calculations according to Din V
18599 are extensive and can, because
of the interactions that occur can
only be resolved by iterative means,
only be done with computer-aided
support. stiebel eltron offers
software solutions for this calculation.
this enables complex calculations
to be carried out, and even includes
manufacturer's data. in this
connection, our specialist department
offers support in all areas concerning
the energy savings order 2007.
