To explain diversity and aggregation, we use following example model of 2 HIU’s.Image Removed

...

First of all, we make a distinction between the calculations within one dwelling, and the calculations over multiple dwellings.

...

Step 1 : recalculation of the tapflows

Step 2 : calculation of the diversity factor and it's effect on the DHW flow and DHW power at DHW side

Step 3 : calculation of the DHW flow and DHW power at CH side, influenced by a regime changing component like a heat exchanger, HIU, storage tank, ...

Step 4 : aggregation of the DHW flow/power with the CH flow/power at CH side

Over multiple dwellings

Step 5a : propagate the DHW flow/power

Step 5b : propagate the CH flow/power
