How about using name such as "Visual Environment Energy Modellin" or "Visual Env" so now name is different than the real one.

EP-Quick is now compatible with the revised input language
of EnergyPlus 3.0. The object names and keywords in the
latest version of EnergyPlus that changed are now supported.
You can still use EP-Quick on all of the releases of
EnergyPlus since version 1.2.1.
EP-Quick is free and available for download from:

Dear all,
When you are rotating the building through 4 different orientations, do you
change the glazing so that the glazing with the highest SHGC is always faces
north, or do you put the glazing with high SHGC on the original north
facade, and then rotate the building so that the high SHGC glazing faces the
east, south and west orientations in subsequent simulations?
Yours faithfully,

Baseline Chiller COP
To: <bldg-sim at lists.onebuilding.org>
Message-ID: <D83FD813F91349C98DF04F42F88467FF at hotinkit>
Content-Type: text/plain; charset="us-ascii"
Regarding to the Performance Rating Method of of Ashrae 90.1 (2004), there
is an issue of determining baseline Chiller COP need to be clarified.
Regarding to the baseline HVAC system, the parameters need to be set
according to Appendix G of Ashrae 90.1 Standard.
According to table G3.1.1A and table G3.1.1B of App. G3.1.1, the baseline
HVAC system for a building with area larger than 150,000 sqft is specified
as variable air volume with reheat with centrifugal chiller >300tons,
whereas the equipment efficiencies should be modeled at the minimum
efficiency levels in accordance with section 6.4 of Ashrae 90.1 Standard.
Then referring to table 6.8.1 J of section 6.4 of Ashrae 90.1 Standard,
minimum efficiencies for centrifugal chiller COP(standard) should be 6.1.
However, What is the minimum efficiencies for the baseline design COP under
the following condition,
1) If the proposed HVAC design is design to work with leaving chilled water
at 42.8F and entering condenser water temperature of 85F,
2) If the proposed HVAC design is design to work with leaving chilled water
at 42.8F and entering condenser water temperature of 89.6F, and this chiller
is designed to be a ice storage system.
Should the baseline design be modeled at COP 6.1 or should the baseline COP
be estimated by the equations listed below the table 6.8.1 J?
Please advise.
Thanks you for any kindly helps.

I would be glad to set up a new mailing list for users of
IES-VE using onebuilding.org, all we need is a name.
Unfortunately, I do not have permission to name the list
IES-VE-users or VE-users or anything that might be
trademarked. If someone can come up with a good name that is
not trademarked, I will set up a new mailing list.

Dear Ulrik,
Since the intent of the Standard is to assign the better glazing performance
to non-North walls, I always rotate the glazing characteristics with the
building. (e.g., I assign the "North" glazing characteristics to the
elevation that, after rotating, faces North)

A90.1-2007 removed the reference to SHGC_All and refers to the Chapter 5
tables. You should be able to use the SHGC_north in the baseline if you

This is an interesting discussion (one that may have already occurred
previously). According to the 90.1 User Manual:
"SHGC - The budget building design's fenestration solar heat gain
coefficient is set to the maximum required for the climate. The
prescriptive standards give SHGC criteria for all orientations and
provide an exception for north facing fenestration. The exception is
not used for the baseline building; the criteria for all orientations
are used for all orientations..."
However, even the LEED-NC EAc1 template differentiates between the North
SHGC and the rest of the fenestration....if the exception is not to be
used, why would the USGBC have a place to enter the SHGC(north) for the
baseline building?? And why would they accept two different SHGCs for
the baseline building on the template?
I can't seem to find any NC or CS CIRs that address this.

When you are rotating the building through 4 different orientations, do
you change the glazing so that the glazing with the highest SHGC is
always faces north, or do you put the glazing with high SHGC on the
original north facade, and then rotate the building so that the high

Sorry, I should have read further before posting. In the LEED-NC
reference guide, it states:
"The four Baseline Design energy models are identical to each other,
except that the building orientation for each model is modified as
described in ASHRAE Std 90.1 Table G3.5.1a, and the window SHGCs are
revised to reflect the minimum ASHRAE Building Envelope Requirements for
the revised building orientation."
In other words, the USGBC, whether on purpose or not, has provided its
own exception to 90.1 that allows you to use the SHGC(north) in the
baseline models. And yes, after rotating, you have to reassign the
proper SHGCs to the new "north".

I'm no statistician, but I've always been dubious about that calculation.
You are taking the mean of two means, which seems to be getting farther
and farther from actual data.
It also seems to punish some of the climates that are best suited for
natural ventilation, since having cool nights significantly drops the
acceptability limits. I assume they are pushing you to take advantage of
night pre-cooling and thermal mass, but I find it curious that there are
no allowable hours outside of the range. All of the pre-cooling in the
world isn't going to help you keep the temperatures down during that one
string of 90 degree days in the tmy2 file...

There is a small difference between the arithmetic mean of the monthly

data. Like you say, it's probably a legacy from the old pen and paper
days.
I've heard that some would use occupied period only to calculate the
mean. However, I can not find any reference in the text of A55 to
justify this. Being able to average the warmer occupied hours would make
things a whole lot easier - even the 80% acceptability temperature can
regularly be lower than the summertime peaks. It's a tough call for
natural ventilation.

All;
I certainly do NOT think the 2007 PRM requires that the baseline glazing "North" SHGCs be "moved" as the "North" exposures change in each of the simulations that generates the "baseline building performance." I could see how one might think that, but say it ain't so. I assume the baseline "North" SHGC is applied to what would be "North" glazing in the proposed and unrotated baseline models, and those glazing parameters are left in place for that facade as the baseline model is rotated. I don't think this has been fodder for a USGBC CIR or ASHRAE interpretation yet, but maybe I'm out of touch. Addendum A to 2004, which removed the glazing redistribution requirement, still used SHGC_all for all baseline glazing. I thought this had been incorporated verbatim in the 2007 edits but noooooo. Time to get out the magnifier and channel my inner attorney.

A90.1-2007 removed the reference to SHGC_All and refers to the Chapter 5 tables. You should be able to use the SHGC_north in the baseline if you follow 2007.

Hi Brandon;
I've been doing some "reverse engineering," and I keep coming back to the
same problem: my FLOOR AND SPACE polygons appear in eQuest exactly where I
expect them to, but all of the EXTERIOR-WALL polygons, if no translations
are applied (ie X, Y, Z, AZIMUTH, TILT = 0) , appear rotated 180 degrees
around the building coordinate X axis relative to where I would expect them
to be. Also, oddly, the TILT and AZIMUTH transformations, when specified,
take place relative to this rotated coordinate system -- ie, the AZIMUTH
rotation is about the buidling coordinate *negative *z-axis -- while the
translation transformation (as specified by X, Y, and Z) take place as
expected (in the building coordinate system).
Very strange stuff. I get the feeling that this has something to do with the
EXTERIOR-WALL coordinate system being dependant on the SPACE coordinate
system which is, in turn, dependant on the FLOOR coordinate system. As it
stands, my FLOOR, SPACE, and EXTERIOR WALL object that represents the floor
all use the same POLYGON object -- does anyone know if this in itself is a
problem? My instinct is that I'm somehow misunderstanding this relationship,
but I've done some fiddling in this regard and haven't been able to change
very much...
Again, if anyone has any insight on this issue, it would be greatly
appreciated.
Thanks a lot,
Josh
