I am trying to model a rainwater collector on the roof of a building that will be sent to a rainwater tank as a WaterUse:Storage component in EnergyPlus. That tank is then connected to my DHW WaterUse:Connections component as the "Supply Water Storage Tank Name" to supply cold water when the tank has ample volume, otherwise mains water will be used. Here are my issues:

1. When it is raining, my output .csv file doesn't show a change in rainwater tank volume from the initial value.
2. My annual simulations show no change in mains water used for DHW loads whether rainwater is collected or not.
3. The volume for the graywater tank also doesn't change from the initial value.

Here is an excerpt from the .idf file:

I have created a Site:Precipitation object with an annual schedule from the PrecipitationSchedulesUSA.idf dataset, and that works fine. Any help would be greatly appreciated. I've thought about if there should be a pump connected to the rainwater loop, but there aren't input or output nodes for the WaterUse:RainCollector or WaterUse:Storage components.

What are typical charging rates for creating a building energy model? Do you charge by geometry features (vertex, floors, etc.), equipment features (HVAC, lighting, etc.), or total time spent creating the model?

Is there an online resource of weekly or monthly meetings for energy modelers to interact with each other? Local IBPSA chapters or some other organization body like MeetUp, perhaps?
