Carol,
 
I got the attachment from an eQUEST training CD. Marlin Addison is
listed as the author.

I also found some formulas when tooling around in the archives the other
day and could love to get comments, if any about their utlity:

EIR=(1/EER-0.012167)/((1/3.413)+0.012167)
and
EIR=((1/SEER*0.778+1.4)-0.012167)/((1/3.413)+0.012167)

Anyone remember these that knows the source and utility? Is there one
for HSPF?

Hi Michael, to modify the EIR (which is in Btu/Btu) in the detailed
mode, click on the Air-Side HVAC icon at the top of your screen, then
double click on the heat pump. Under the cooling and heating tabs you
will find a Unitary Power tab where you can change your EIR.

Hi All,
 
I am still fairly new to equest and I am having a bit of trouble with
setting up my HVAC.  I created a building model using the equest wizard
and now I have made a number of changes within the detailed DOE2
interface.  The building uses air source heat pumps for the HVAC and I
would like to change the EER/COP values without going back to the
wizard, but I cannot figure where these values are stored.  Is there an
easy way to make changes like that within DOE2?
 
Thanks,
Michael Shields
