Add Radiant HVAC Templates

[chriswmackey]

I think this should be done fairly similarly to the way it is implemented in Legacy where an Internal Source material can be put in a material layer of a construction. The only difference will be that people can use this special material type to customize the pipe spacing and thickness.

Then, if the Room has a Radiant HVAC assigned to it, this internal source layer will get connected to low-temperature hot/cold water loops following a template specified by the user. Given what already exists in the OpenStudio Standards gem, I think we can easily support the following Radiant templates:

• DOAS_Radiat_Chiller_Boiler
• DOAS_Radiant_Chiller_ASHP
• DOAS_Radiant_Chiller_DHW
• DOAS_Radiant_ACChiller_Boiler
• DOAS_Radiant_ACChiller_ASHP
• DOAS_Radiant_ACChiller_DHW
• DOAS_Radiant_DCW_Boiler
• DOAS_Radiant_DCW_ASHP
• DOAS_Radiant_DCW_DHW
• Radiat_Chiller_Boiler
• Radiant_Chiller_ASHP
• Radiant_Chiller_DHW
• Radiant_ACChiller_Boiler
• Radiant_ACChiller_ASHP
• Radiant_ACChiller_DHW
• Radiant_DCW_Boiler
• Radiant_DCW_ASHP
• Radiant_DCW_DHW

To implement these templates, we'll just start with what is offered for FCU systems and lower the loop temperatures before connecting up to the internal source.

@chriswmackey
This is something topical to the project done in design builder that I abhor design builder for: while knowing how to IronBug it:
with what I've learned from the round of user_data in HBE: Be happy to "next on my list" this unless there is more pressing that some minion attention to would be preferred?
