[Bldg-sim] LEED and Title-24 and E-Quest and ASHRAE-90.1

[Matutinovic, Luka]

Robert,

You are correct in that presently eQuest does not have a built-in 90.1
compliance module.  You will have to create two buildings using Appendix
G (Performance Rating Method) as a guide: one will be the ASHRAE
reference building, and the other will be your actual design, which has
to comply with the mandatory provisions of 90.1 (sections 5.4, 6.4, 7.4,
8.4, 9.4 and 1.4).

Personally I can't wait for the compliance module.

Hope that helps.

Subject: [Bldg-sim] LEED and Title-24 and E-Quest and ASHRAE-90.1

I am in need of some help and guidance on using E-Quest to qualify for
LEED credits.  I am working on a California project with water source
heat pumps, that was initially analyzed using Energy Pro and showed 
barely passing Title-24 requirements.   The majority of high usage was 
in the cooling tower fans, which appeared to be modeled as running 
whenever a cooling load was present.   We were then asked to try for 
LEED certification and knowing that the Energy Pro run was barely
passing, we needed a better modeling tool and probably a more efficient
system.  In order to model this better, we decided to use E-Quest so we
could put individual cooling tower cells into the model and also use
some add-ons provided by Climate Master for their higher efficiency
units .  The first run of E-Quest failed to pass the Title-24
requirements. 

I admit to being inexperienced on E-Quest, but I did read everything I
could find and followed every guidance I could find, but I could fine
nothing about using E-Quest to compare with ASHRAE 90.1 (which I believe
is an option for LEED certification).  I also believe that when the
Title-24 compliance run is done, some default values are used that may
make our project seem less efficient, so I am trying to work around that
as well.

I would appreciate hearing any ideas that anyone has, but I would most
appreciate finding some written guidance regarding using E-Quest to
qualify for LEED certification.  Alternatively, any written guidance
that is available regarding using E-Quest for comparison with ASHRAE
90.1 (which I do believe would allow for LEED certification) would be
helpful.  I have found nothing on these topics in any of the published
E-Quest documentation that I have found.  One guide says that comparison
with 90.1 is "planned for the future" but that is about it.  That guide
was published in 2003, so I hope that we are in the future, but I do not
know for sure.

Lastly, if anyone has any written or anecdotal guidance regarding using
E-Quest to show compliance with Title-24, I'd really like to see that
too.  Is there something that prevents E-Quest from using the actual
model set (not the defaults) that can be defeated to show compliance?  
Again, I am not asking for somebody to show me how to do it, just for
somebody to show me an FAQ or a publication of some sort that I can use
in this situation.

Lastly, if I fail to figure this out, if there is someone who would be
willing to work as a consultant on the project, please contact me
off-list at 916 966 9060 or via robert at wichert.org .  E-Mail is probably
best.

Thanks for your time in reading this and for any advice that you might
provide.

Sincerely,


Robert Wichert, P. Eng
