Reliable simulation of buildings' energy performance requires, amongst other things, the availability of detailed information on the magnitudes of incident solar radiation on building facades. However, the availability of the measured data concerning the incident solar radiation on vertical surfaces is restricted to only few locations. In addition, concurrent measurements of horizontal global and horizontal diffuse (or direct normal) irradiance data are likewise available only for a limited number of locations. In contrast, global horizontal irradiance data is available for many locations. This research demonstrates how to computationally derive incident irradiance values on vertical (or otherwise inclined) building surfaces from measured globalirradiance values. Given this context, three methods are considered to compute incident vertical irradiance values based on measured global horizontal irradiance data. Vertical solar irradiance measurements are described. Then, the computationally derived values are compared withcorresponding measurements. The results are evaluated based on their correlation coefficients and relative error. Finally, the application of horizontal-to- vertical irradiance mapping is demonstrated using the case of an office building at Vienna University of Technology.
