Hello Dear All,
I'm modeling a building with office in top floors and retail in lower
floors. My baseline modeling calibration looks good. But when I looked at
further the modeling results, I found the following problems:
*1) Many zones have insufficient heating capability. *The warning messages
are like following:
ZONE EL1 North Perim Zn (G.N3)
might have insufficient heating capability.
Check that the SYSTEM or ZONE HEATING-CAPACITY plus this
ZONEs BASEBOARD-RATING is adequate to maintain the ZONE
specified DESIGN-HEAT-T for the calculated peak ZONE load
(see LS-A or LS-B for the ZONE peak load.)
ZONE EL1 North Perim Zn (G.N3) has a THERMOSTAT-TYPE
of REVERSE-ACTION, which, when added to the issues listed
in the messages above, will cause excessive underheating.
For more details, you can look at the detailed simulation output file.
*2) The model result has many unmet hours.*
PERCENT OF HOURS ANY SYSTEM ZONE OUTSIDE OF THROTTLING RANGE = 10.98
PERCENT OF HOURS ANY PLANT LOAD NOT SATISFIED
= 0.00
HOURS ANY ZONE ABOVE COOLING THROTTLING RANGE
= 754
HOURS ANY ZONE BELOW HEATING THROTTLING RANGE
= 347
I'm wondering if you can help me figure out these problems and give me
guidance on how to resolve them.
For your information, I also attached the equest models and weather file.
Please let me know if you need more modeling information.
Thanks,
Qi
