Filippo and Jean,<br>
My approach to autosizing has been to run the building model in
energy rate control with no setups or setbacks in the thermostat and
to records the maximum hourly value of the QSENS NTYPE from Type56.
This gives you the peak hourly sensible heating and cooling load for
each zone in the building and is very similar to the autosizing that
other programs do. You can then change the building back to a
temperature level control simulation and use the peak heating and
cooling loads to choose equipment. Be careful that you're sizing the
cooling equipment based on a sensible demand not based on total
cooling demand.<br>

<div dir="ltr">With Trnsys everything is possible. The drawback is
the time it takes. Reporting needs to be setup for a lot of
outputs (hours load not met amoungst others). One of the things
I find very "rough" is that there is no "auto-sizing". You'll
need to manually "auto-size" all componants of the system.<br>

Simulating the 90.1 Appendix G baseline systems almost
always involves the use of multiple Types. If you have
questions about a particular baseline system, please tell me
which one and I can probably give you some guidance. For the
most part the TESS HVAC library contains the components that
you would need. We do have a VAV air handler component that
I have used for LEED simulations although it is not
officially part of either the standard library or the TESS
Libraries.<br>
<br>
As far as the files that you need to submit along with
your LEED forms, in my experience this is a bit of a
guessing game between you and the reviewer. TRNSYS does not
have the kind of standardized forms that LEED reviewers are
used to. I usually submit the *.dck and the *.b17. In
general I use a Type46 (printegrator) to generate one or
more output files the contain the monthly power draw of all
the active components of the systems (fans, pumps,
compressors, heaters, etc.). I then put the contents of
those files into a spreadsheet that I submit to the
reviewer.<br>

Hi everybody,<br>
has anyone experience LEED simulation in TRNSYS
17?<br>
<br>
I have two questions:<br>
1. is there any specific type developed, or a guideline,
to simulate HVAC plant according to appendix G ASHRAE
90.1;<br>
2. what are the files that needs to be attached to the
LEED PI form? Is there any type or procedure guide to
print the correct forms?<br>
<br>
Thanks<br>
