reviewer is referring to is in Section G3.1.3.11 (not G3.1.11). The model you
sent currently has one primary CHW pump attached to each of your two chillers,
a separate primary CHW pump on the primary loop, one secondary CHW pump and one
condenser water pump. You labeled your primary chiller pumps “Secondary
Pump CHW 1” and “Secondary Pump CHW 2”, which is probably why
the reviewer thinks you only have one primary pump (the one on the primary CHW
loop labeled “Primary CHW Pump”). I suggest making the following

<p class=MsoNormal><em><i><font size=3 face=Arial><span lang=DE
style='font-size:12.0pt;font-family:Arial;mso-ansi-language:DE'>"It
appears as if the pumps and circulation loops were not modeled correctly for
the Baseline Case. It appears based on the PS-C reports that there is only one
primary chilled water pump and one condenser water pump for the Baseline Case.
However, ASHRAE 90.1 Section G3.1.11 requires that each chiller be modeled with
separate condenser water and chilled water pumps interlocked to operate with
each associated chiller. Please model two primary chilled water pumps and two
primary condenser water pumps in accordance with Section G3.1.11. Also update
the chilled water valves to two-way valves so that the secondary chilled water
loop operates as a variable flow loop with pumps riding the curve. Provide
updated PS-C reports confirming that the changes have been made."</span></font></i></em><span

<p><em><i><font size=3 face=Arial><span lang=DE style='font-size:12.0pt;
font-family:Arial;mso-ansi-language:DE'>"It is unclear why the pump flow
for the secondary chilled water loop is so much larger than that of the primary
chilled water loop when the temperature differential for both loops is expected
to be the same. It also appears based on the outputs in PS-C that the secondary
chilled water loop is operated at the same load for every hour that it is on
even though it is a variable speed pump. Please update the secondary chilled
water loop flow to be consistent with the primary chilled water loop flow, and
confirm that the secondary chilled water loop is operating as a variable flow
loop."</span></font></i></em><span lang=EN-GB style='mso-ansi-language:
