[Bldg-sim] Manual J,D and S Calculations

[RobertWichert]

In California, we can use either Manual J or ASHRAE methods for loads.  
EnergyPro uses the ASHRAE methods, so that is OK to use.  I would ask 
how EQuest does loads, and if it's ASHRAE, I'd use that if you are 
familiar with it.  We are also allowed to use Manual D or ASHRAE methods 
for ducts and the ASHRAE methods are in the ASHRAE handbook.  For simple 
residential, it's a simple duct losses spreadsheet that you can make up 
yourself.
