[Bldg-sim] Estimating VAV savings

[Adam Gonthier]

Hi John

 

Thanks for your reply.  Since we already have the BIN analysis, we are
trying to be consistent with what we have rather than redoing a whole
bunch of work (in the sense of building an eQuest from scratch).

 

Thanks again.

My drift is that it would be easier to integrate both technologies in
ther eQuest program. There you would have the VAV rise and fall of
airflow, coupled with the air economizer effects.

 

Blatent plug for ther program..

	Hi all

	 

	I am attempting to estimate the cost savings which result from
upgrading an air distribution system from constant air volume to
variable air volume by the addition of VAV boxes.  We have already done
a BIN analysis for estimating the savings resulting from the addition of
outside air economizers, and I have had some difficulty in figuring out
how to modify this analysis to incorporate the VAVs.  

 

I assume that I can do this by figuring out how to adjust the supply
flow for each temperature bin, but I am not sure how to do this
appropriately.

 

Can anyone please help me on this, or direct me to a resource that I may
have overlooked while doing my research?

 

Thank you all very much
