[Equest-users] Equest-users Digest, Vol 79, Issue 12

[Sharad Kumar]

Hi Molly,

As far as Baseline system is concerned , we can choose the system type from
table G3.1.1A.
If the heating system for the building is Electric and hybrid, we can chose
the system type from the left column (i.e. System-1,3,5,7) from the table
G3.1.1A.
Also, if the heating system has to be chosen, it should be considered from
the table G3.1.1B. For example for system type-3 the heating system for
Baseline Case is fossil fuel furnace.
>From the below given excerpt  from the ASHRAE 90.1, you can refer the
Baseline case.
Hence the heating system can be chosen from these tables.
You have to keep in mind the type, area and number of floors of the
building.
