Description
This query calculates the (weighted average) share of residences and buildings
connected to a district heating network and then returns the average length of
the main distribution pipelines per connected building (residence object)
depending on which 'bracket' this weighted share is in.
The more objects are connected to the network, the higher the bracket and the
higher the average pipeline length per connection.
It is assumed that the total share of all temperature levels of district heating
determines the bracket.
