Also, the ground and building DSM is saved in the output folder for later use. The column voxel is decided based on the pixel resolution of the input data. If zero values are found (especially at the end of the row) that means that the wall column has reached its maximum height. The following columns are irradiance for each wall voxel starting from the ground and moving upwards as going right in each row. The Energyyearwall.txt is formatted in the following way: first and second column is the relative row and column number from upper left corner of the modelled grid. Energyyearwall.txt show total wall irradiance for each wall column. The geoTIFF Energyyearroof.tif show pixel wise total irradiance in kWh. If this is ticked, Energyyearroof.tif will be loaded into to the map canvas.Īs mentioned earlier, three mandatory datasets are saved if the model runs successfully. Add Roof and Ground Irradiance Result Raster to Project.Also, the ground and building DSM is saved in the output folder to be used later in a SEBE visualization plugin (UMEP -> Post-processing -> Solar Energy -> SEBE (Visualisation)). One raster showing irradiance on ground and building roofs named Energyyearroof.tif is saved as well as a text file of wall irradiance (Energyyearwall.txt). (2015).Ī specified folder where result will be saved should be specified here. For more detailed information on this, see Lindberg et al. the core loop in the model iterates 145 times. SEBE first distributes the radiation on 145 sky patches on the sky vault and then generates shadows on the DSMs based on these patches, i.e. When the box is ticked, it is possible to save the radiation distribution from the sky vault calculated from the meteorological file. Since diffuse and direct components of short wave radiation is not common data, it is also possible to calculate diffuse and direct shortwave radiation (see above).
