Hi William, <br>
We did a Leed warehouse herre in Canada but it was version NC 1.0, your
2.2 version.<br>
In that case process energy has to be remove for comparaison with
baseline.<br>
We aslo can reclaim up to 2 credit in process energy i.e. heat recovery
from refrigeration.<br>
If it is Leed 2009 than you have to include process energy in baseline
and proposed.<br><br>
Hope this help<br><br>

Hey all,<br>
<br>
I’m about to begin a LEED energy model for a warehouse project that
contains a very large process load. It will be a major renovation
project. The building will be broken out as 50,000 sq ft office and
300,000 sq ft warehouse. The anticipated HVAC systems on the project are
package rooftop units with DX cooling/gas heating for both the office and
warehouse areas. The warehouse space requires cooling and heating.<br>
<br>
Two issues that come to light:<br>
<br>
1. Large Process Load<br>
a. Anticipated process load will
consume roughly 40-60% of the buildings annual energy consumption. The
Exceptional calculation method has been considered. However, the process
being done at this facility is extraordinary and there is not a
“baseline” to compare savings off of.<br>
2. Baseline System<br>
a. Based on the size of the
warehouse, System 7 will be modeled. This system is a packaged rooftop
VAV with reheat with chilled water and hot water boiler system. Based on
previous experience and preliminary modeling results, the baseline system
will be more energy efficient than the package rooftop units with DX
cooling/gas heating. There’s been a suggestion by our team to request a
LEED Interpretation and to possible change the baseline system to also
packaged rooftop units with DX cooling/gas heating as that is typically
designed for warehouse type facilities.<br>
<br>
Based on these two issues, I am having a hard time foreseeing this
project being able to hit the minimum 5% savings requirement on major
renovations. I searched the LEED Interpretations database but didn’t find
one that dealt with a project that had both these issues.<br>
<br>
Any suggestions? <br>
