[Equest-users] Unmet Hours

[Nick Caton]

Michael, 

 

90.1's passage (G3.1.2.2) regarding unmet hours requirements is
something I had to re-read many times to get my head fully wrapped
around it... Here's my current interpretation:

 

1.       You need to have 300 or fewer hours in each model.

2.       The proposed is not allowed to perform worse than the baseline
by more than 50 unmet hours.  If it does you have to make the baseline
"underperform" so they're within 50 of each other. 

3.       The baseline is permitted to perform worse than the proposed
(by any degree) as long as it's still 300 or fewer unmet hours.

 

You haven't said whether you're talking about your baseline or proposed
model, but the above points should guide you as to whether you need to
make an adjustment.  Refer to G3.1.2.2 for review and further info.

Subject: [Equest-users] Unmet Hours

 

Hi All,

 

I am working on filing out the LEED paperwork for submittal and for
unmet hours I am wondering does the reviewer want the total unmet load
hours for the building, or an average per zone?  My building has about
100 zones, most of which have 0 unmet hours, but I have one zone which
has significant (more than 50) unmet hours.  Does this mean my model
exceeds the requirement that the difference between the baseline and the
proposed be less than 50 hours?

 

Thanks for any advice.
