bldg-sim@lists.onebuilding.org<BR><B>Subject:</B> [Bldg-sim] eQUEST - percent of
hours outside throttling range<BR></FONT><BR></DIV>
<DIV></DIV>Dear all,<BR><BR>I'm working on the energy model for a school
building with 43 zones with each zone connected to a ground source heat pump.
Right now the model is for design development but eventually the same model
could be used for LEED.<BR><BR>I can't seem to get the percent of hours any
system zone outside of throttling range below 48%. The system sizing ratio of
all airside systems is currently at 2. As per HVAC design, the depth of ground
source loop is 400 ft and I tried increasing it to 600 ft and that only helps a
little.<BR><BR>In the SS-R report, the undercooled hours for different zones are
in the 200+ range while the underheated hours are in the range of 200 to 500.
I'm using the Dodge City, KS weather file.<BR><BR>Also the current annual energy
consumption is as low as 18.1 kBtu/ft2, I know that will change as the % hours
outside the throttling range changes but still seems very low.<BR><BR>Thanks for
your help,<BR> <BR>RAMANA KOTI Assoc. ASHRAE LEED® AP <BR>Sustainable
