[BLDG-SIM] Energy-10 and LEED

[Marcus Sheffer <sheffer@xxxxxxxxxxxx>]

Energy 10 software is acceptable for LEED even though you are correct on
ECBM in 90.1.  The LEED Reference Guide lists some exceptions to the
90.1 ECBM.  For the proper building type and systems, Energy 10
would be acceptable according to my understanding.

The requirements for LEED 2.1 Energy and Atmosphere credit 1 state:
        Reduce design energy cost compared to the energy cost budget for
energy
        systems regulated by ASHRAE/IESNA Standard 90.1-1999 (without
amendments),
        as demonstrated by a whole building simulation using the Energy
        Cost Budget Method described in Section 11 of the Standard.
In my quick check of the standard, the modeling software must be able to
model at least ten (10) thermal zones.  If we are going by the letter,
Energy-10 does not qualify because it can only model  two (2) zones.  The
DOE-2 website claims that the ASHRAE standard was based on DOE-2 analyses,
so it looks like DOE-2 is the winner.

(I personally have not used Energy-10 or DOE-2.  I am working primarily with
EnergyPlus.)

I hope I have helped.

I am working on a project which had registered for LEED certification. Now
we have to make decision of the energy simulation tool we are going to use
to optimize energy performance.  Our choice is DOE-2 or Energy-10.  I am not
sure if Energy-10 is a qualified energy simulation program for LEED
certification and I appreciate if anyone could tell me more about it.

Thank you for your help!
