Feature Idea Roombased Heat Degree Days

[JonasGhost]

Roombased Heat Degree Days would allow the calculation of rooms that have very different room temperatures, e.g. heated garage.
Also the option to exclude rooms/heat delivery systems from the hydronic system would be neat. E.G. for mini split air conditioning.

Dynamic simulation for each outside temperature with the kWh usage and heat loss for every temperature.
This would help for sizing the heat pump. This is helpful for finding the optimal bivalent point.
