This module scales the default layer with a given factor. Often heat and cold demands are reported in an aggregated manner in energy balances. Using this calculation module, it is possible to us the distribution of default Hotmaps heat and cold demand density maps to dis aggregate such values. This is done by scaling the default Hotmaps heat and cool density maps up or done to reach the desired value.
This module scales the default layer with a given factor. Often heat and cold demands are reported in an aggregated manner in energy balances. Using this calculation module, it is possible to us the distribution of default Hotmaps heat and cold demand density maps to dis aggregate such values. This is done by scaling the default Hotmaps heat and cool density maps up or done to reach the desired value. The calculation module provides a new raster by scaling a raster density map by a user-chosen factor. It generates a new raster by multiplying each cell of the input raster by the given factor.
The input parameters and layers, as well as output layers and parameters, are as follows.
Input layers and parameters are:
Output layers and parameters are:
Each cell's value of the input raster is multiplied by the multiplication factor.
If we know the total consumption of an area, and the indicator Total head demand does not correspond this value, it is possible to scale the heat demand by the ratio (Total_real / Total_default). The following figure gives the example of a multiplication factor value of 0.5.
Here you get the bleeding-edge development for this calculation module.
Here, the calculation module is run for the case study of Vienna, Austria. First, use the "Go To Place" bar to navigate to Vienna and select the city. Click on the "Layers" button to open the "Layers" window and then click on the "CALCULATION MODULE" tab. In the list of calculation modules, select "CM - Scale heat and cool density maps".
After pressing run a new density map is calculated on the basis of the selected map. The default value here is the heat density total map. After the calculation, the total new heat demand is shown on the right side, under indicators. (Here the default value is 1 and therefore, no change in the indicators occurs).
After closing the calculation modules and switching to the layer section, the newly calculated heat density map can be found at the very bottom of the LAYERS tab. This layer can be downloaded by the user and also can be uploaded to the user account for the purpose of further calculations.
