Dreidimensionale Ermittlung des thermischen Komforts mit detaillierter Berechnung der Strahlungstemperaturen auf Basis von Messdaten aus Drohnenbefliegungen.

Urban thermal comfort maps based on a three‐dimensional sampling algorithm and UAV‐based radiometric measurements A new methodology and workflow to assess outdoor thermal comfort and thermal stress in urban areas is developed. The new methodology is applied to a case of an urban quarter in the city of Graz. The method recognizes the significance of detailed and accurate spatially resolved determination of mean radiant temperatures taking into account all relevant radiative components. The method relies on 3D‐data acquired from drone (unmanned aerial vehicles UAV) flights, pre‐existing city models and a Monte‐Carlo ray‐tracing algorithm using directional sampling curves based on a 3D‐model with human topology. The detailed three‐dimensionally determined mean radiation temperatures are used to calculate thermal comfort level maps using UTCI and PMV calculation. [ABSTRACT FROM AUTHOR]
