Title:
Abstract:	Für viele bauhysikalische Simulationen und Nachweise wird als wesentliche Eingangsgröße das Raumklima benötigt. Besonders detaillierte Angaben sind für instationäre Berechnungen erforderlich. Literaturangaben über die jahreszeitliche Entwicklung des Raumklimas sind meist recht allgemein gehalten und unterscheiden nicht nach Klimaregion, Belegungsprofil oder Raumnutzung. Ausgewertet wurden Raumklimamessungen aus zwölf Wohnzimmern eines Jahres. Aus den Messwerten werden außentemperatur- und zeitabhängige Ausgleichsfunktionen für die Raumlufttemperatur, die Raumluftfeuchte und die Taupunkttemperatur abgeleitet. Während des Messzeitraumes waren die Wohnzimmer schadensfrei und wiesen unterschiedliche Belegungsprofile auf. Aus den Messergebnissen wird ein Raumklimamodell für Wohnzimmer abgeleitet, womit auch eine Überprüfung und Bewertung von Simulationsergebnissen hinsichtlich des Tauwasserrisikos an der Wandoberfläche fensterbelüfteter Wohnzimmer möglich wird. Analysis of indoor climate measurements and determination of typical dew-point temperatures in naturally ventilated living rooms. The indoor climate is an essential input variable for many simulations and analyses in building physics. Detailed data are especially necessary for the transient calculations. Most existing information in the literature about indoor climate is universal and forgoes a differentiation between climatic region, occupancy profile or utilisation of single rooms. This paper presents room climate measurements over a period of one year in twelve living rooms. The measured values of indoor temperature and relative humidity serve to derive the dew point temperature. Dynamic, time-dependent regression functions are determined for those parameters. Furthermore, the indoor climates dependency on outdoor temperature is also being analysed and will be described by statistical functions. During the measurement period, the living rooms were free of mould and moisture damage and had different occupancies. The measurement results can be used to derive an indoor climate model and allow for an evaluation of simulation results regarding the risk of condensation on the inside wall surfaces of naturally ventilated living rooms.
