Dear all,
When submitting the LEED Online templates, I am asked to enter the:
a. Number of hrs heating loads not met
b. Number of hrs cooling loads not met
Are these the same as the BEPS report's "HOURS ANY ZONE ABOVE COOLING
THROTTLING RANGE" and "HOURS ANY ZONE BELOW HEATING THROTTLING RANGE" ?
OR
Shall I add the hours of each month of every zone (the last 2 columns of
SS-F Zone Demand Summary for each zone)? (HOURS UNDERHEATED & HOURS
UNDERCOOLED)
Accordingly, how can we satisfy the ASHRAE requirement for the maximum
unmet load hours of 300hrs?
* Shall I add the hours underheated and hours undercooled of the
SS-F report, or
* shall I add the "HOURS ANY ZONE ABOVE COOLING THROTTLING RANGE"
and "HOURS ANY ZONE BELOW HEATING THROTTLING RANGE " hours of the BEPS
report, or
* Shall I multiply the "% of hours any system zone outside of
throttling range" of the BEPS report by the "hours fans on" of the SS-E
report?
All the three above seem to give me different answers! Which one is the
most accurate?
Many thanks!

There was an in depth discussion of this not too long ago. Look for that
thread and if you still have questions email us again.

Quickly, the answer is your last suggestion: multiply BEPS % by the 'hours fans on.'
This does not break apart the heating and cooling figures, so you must extrapolate in a manner you're comfy with to weight between the two. I reference the zone reports to do this weighting.
Carol's making a good point that will doubtless save you time in the future... Any eQuest user should have the following archive search sites bookmarked in their browser:
- http://lists.onebuilding.org/pipermail/equest-users-onebuilding.org/ (tip: search for my name and the word 'coincidental' for some suggested write-ups on your question)
- http://lists.onebuilding.org/pipermail/bldg-sim-onebuilding.org/
These archives are a primary resource when you have eQuest-specific questions, and you can basically get an instant response if your question has already been discussed ;).
