[Equest-users] checking my glasses?

[Aaron Smith]

That's what I see too.  Sounds unusual, especially since Zone 4 has a
minimum EER in Table 6.3.2 to eliminate economizers.  They're required in
the 2010 version for >/= 54,000btu/h.

has anyone read ashrae-90.1 2007, page 36 ?? it seems to say that climate
zone 4a (new york city) does NOT require air economizers? this is apparently
new york city adopted code  !!

Javed,  I had a similar issue with high pumping energy on a model last year
Send us your .pd2 and .inp and weather file and I can run it on my computer
and see if I can help you find the issue that is pushing your model results
too high.

Send the .INP and .PD2. And version number. Not all of us have gone to 3.65.

am facing a major issue in pumping power annual consumption. The proposed
case pumping power is almost 7 times higher than the ASHRAE baseline case
which  has great impact on my overall anticipated savings. I've generated
hourly report to see the pump operations power and found propose case pump
is running all year round whereas baseline is running as per building
operating hours. I've thoroughly checked all the schedules assigned and it
seems fine to me. My gut feeling is there is some load which is driving the
pump to run throughout the year. I would appreciate if someone can give
expert advice to troubleshoot this.
