Abstract
<jats:p>Contemporary controversy about daylight saving time (DST) is mainly derived
from different standpoints in studies investigating the positive and
negative effects of the clock shift during summer period. From the
standpoint of energy savings, most studies have consensus that the
summertime clock shift in middle latitudes, with a large difference between
winter and summer daylight hours, contributes to energy savings in
buildings. Belgrade?s mid-latitude, moderate-continental climate has a
six-month long heating season and a three-month cooling season. The annual
domination of the heating period assumes that the demand for heating energy
also dominates in the annual energy breakdown for average office buildings.
Since DST covers mainly summer time, the energy breakdown in office
buildings during the DST period is dominated by the energy demand for
lighting and cooling. The shift of time ahead of standard time during the
DST period causes a shift in temperature, daylight availability and solar
energy resources and thus a shift in the potential for the utilisation of
the surrounding energy. This paper investigates how the application of DST
in Belgrade?s climate and latitude influences the change of climate
parameters relevant for the cooling and lighting energy demand in office
buildings.</jats:p>
