Vikram,

If you look at LEED NC CIR ruling date 2/20/2009 you'll find a similar
situation in a hospital, that was told to use PTACs. This is a situation I
looked up a while ago. I modeled my special pressurization requirement
rooms with PTACs quickly and saw the baseline used less energy than my
proposed design with the chiller / boiler. I didn't go back to look into it
in much, I've got that on my list to do. I can only think it was because
the PTACs fan and coils cycle as needed and don't need to keep running like
the chiller and boiler in the hospital. Anyone have any other insight into
this?

Good luck Vikram.

I’m modeling a building that has baseline system 7. If I read this
correctly then all lab spaces will have their own system and that system
will conform to system 3  from table g3.1.1A. Is that correct? If so – are
all of my lab spaces going to be packaged single zone units? That doesn’t
seem right – especially since lab spaces are more than 50% of the building
area in this case.


I’d appreciate anyone’s help with this.

Vikram, you should follow the exception (c) if you have a few zones in a
larger building that have special requirements, different from the bulk of
the System 7.  This I think would be intended for cold rooms, server rooms,
etc.

For your case with roughly 50% labs and 50% other, you may instead want to
use the exception (a) to add a second system type in order to account for
differences in space requirements between labs and other spaces.

The design building is probably a good guide – if you are accomplishing
your proposed design with one system, then you might find some way to use
one system 7.  If you have separate lab/office AHUs in the proposed design,
then two systems under exception (a) may be called for.

Depending on the size of the lab, you may end up with several System type 3
or 4 in the baseline, but for larger labs I think the intention would be to
make two System 7’s.

You may also want to look for the Labs21 guide to Appendix G which includes
some other unrelated suggestions.

I can only find that Energy Plus has done the test, but not that it is
BESTTest certified?

What about TAS 8.5, does anyone know where the BESTTest certification is?

All the EnergyPlus testing reports are posted on the EnergyPlus web site:
http://energyplus.gov/testing.cfm
ASHRAE Standard 140-2007 incorporates many of the IEA BESTest methods.  IEA
does not certify software--just provides tests.

Hi Ross

Typically the vendors publish their BESTEST data online. The BESTEST system
is one of self-certification, not a central authorising body….. (see
http://www.iea-shc.org/task34/index.html )

ASHRAE Standard 140 incorporates some of the IEA BESTEST suite and I
understand over time will incorporate more. (
http://www.nrel.gov/docs/fy06osti/40360.pdf )

I am not aware that ASHRAE ‘certify’ software in the way you seek.

Dear,

could anyone help me out with conversion factors primary energy to
electricity for Canada and Italy?

Thanks!

Hello,

We are in the very early stages of a project and are weighing the pros/cons
of a VRV/VRF system vs. geothermal. Any general lessons learned with using
VRV/VRF systems, or pros/cons of certain software packages in modeling them
for demonstrated energy savings?

Thanks,

I believe EnergyPro can model these systems.

Hi Allison
Trace 700 can model VRV/VRF systems.
I haven't tried in Trace before, but, looks pretty easy.

Awhile ago I found a lot of this type info on Natural Resources Canada's
energy webpage:
http://nrcan.gc.ca/eneene/statstat/index-eng.php

it's huge, but maybe some strategic searching will get you to PE factors

 I created a chilled water meter and its utility rate. For the utility      
 rate, all parameters are either left blank or undefined except taxes are   
 set to base. After exporting the DOE2 sim report, I found there is still a 
 charge for chiller water meter. Does anyone know why the charge is not     
 zero for the chilled water meter?                                          
                                                                            
 Thanks,
