Title:
Abstract:	Unter Verwendung von an drei verschiedenen Standorten in Kassel gemessenen Klimadatensätzen der Jahre 2001, 2002 und 2003 sowie des Testreferenzjahres 07 des Deutschen Wetterdienstes wird der Einfluss des Standortfaktors Klima auf den Heizwärmebedarf und den Kühlkältebedarf mit Hilfe dynamischer Gebäudesimulation ermittelt und dargestellt. Hierzu werden für typische Wohnnutzungen Randbedingungen gewählt, für die das thermische Gebäudeverhalten basierend auf unterschiedlichen wärmetechnischen Standards verschiedener Baualtersklassen untersucht wird. Zur Beurteilung des thermischen Raumklimas wird die Anzahl der Übertemperaturgradstunden ermittelt und eine Beurteilung mittels PMV-Indexes vorgenommen. Um die Unterschiede in den gemessenen Klimawerten an den Messorten aufzuzeigen, werden einige wichtige Einflussgrößen anhand von ausgewählten Windrosen, Ereignistagen, mittleren Jahreslufttemperaturen und Globalstrahlungswerten dargestellt. Aus der Bandbreite der Ergebnisse lässt sich feststellen, dass eine genauere Betrachtung des vorherrschenden Standortklimas für die Innenraumbetrachtungen sinnvoll ist und weitere Untersuchungen zur Bereitstellung solcher Daten erfolgen müssen. The effect of microclimate on the energy-related and thermal behaviour of buildings, taking the German town Kassel as an example. The effect of local climatic conditions on heating and cooling requirements is determined and illustrated with the help of dynamic building simulation, using climate data sets measured at three different locations in Kassel in the years 2001, 2001 and 2003, as well as those of test reference year (TRY) 2007 of the German Meteorological Service (DWD). For the properties, which represent typical residential uses, boundary conditions were select ed for which the thermal behaviour was studied for the different thermal insulation standards of buildings of different constructions dates. In order to determine the thermal room climate, the number of excess temperature degree hours is determined and the assessment carried out using the PMV index. Some important parameters are presented with selected wind roses, event days, average annual air temperatures and global radiation values in order to illustrate the difference in climate values measured at the respective locations. The range of results allows the conclusion that a more detailed study of the prevailing local climate is merit ed for the study of indoor climate and that it is therefore necessary to carry out further studies so that such data can be established.
