Dear all,
I'm modeling a commercial kitchen under the LEED for Retail rating system.
Per the end use classifications in the LEED template Section 1.6 Table
EAp2-4, its seems advisable to have process loads output from eQUEST
separately along the lines of Refrigeration, Cooking, commercial kitchen
equipment.
I currently have all of them lumped under equipment loads in two different
HVAC zones which makes the program output all the consumption under one
heading 'miscellaneous equipment'. This captures the equipment's latent
and sensible contribution to heating and cooling loads. (Accurate but no
breakdown)
If I created separate meters and input the process equipment as direct
loads, I'm unable to assign the heat they emit to any particular HVAC zone
which is unacceptable considering their contribution to the heating and
cooling loads. Kind of a catch-22. This method also does not allow
differentiation between sensible and latent contributions. (Broken down but
not accurate)
Is there a workaround?
Thank you,
Ramana.
Hi Ramana,
One option would be to create separate meters and input the process equipment as direct loads (electric or gas consumption) as you have described. You could then go to the individual space(s) and under the 'equipment' tab define an internal energy source with the source type set to 'process' (internal energy sources deemed process will not contribute to a utility load). This will effectively create a heat gain (or loss) within the room and you can assign the appropriate fraction of sensible/latent gain. This should allow you to define the input power as direct loads on meters, and subsequent internal gains in specific spaces.
