I have been dealing with Title 24 energy calculations, which in plain English means that in order to get a building permit you need to be compliant with projected energy usages based on the structure’s square footage, insulation for walls/ceilings/windows, etc.
I thought it would be straight-forward and just lease solar panels from SolarCity, but unfortunately you cannot offset your energy calculations with solar electricity. So I am looking at solar thermal heating for both radiant floor heat and pre-heating hot water in order to avoid propane. I have to weigh that option against a simple heat-pump system combined with propane.
But the good news is that many of the drawings for the plan set that I need for submitting a building permit are falling into place! The target for submitting the plan is June 18th!
