Hello:

I have submitted projects to LEED using the same methodology without any 
problems.  Did you model custom performance curves?

Perhaps you explanation was not clear?

Subject: [Equest-users] VRF in eQuest and LEED

 
Hello everyone, 
 
We are applying for a LEED certification in a project which includes a VRF 
system in several areas.  In order to model such system, we followed the 
methodology described in the document “Energy Trust of Oregon”; and submitted  
an explanation to the LEED reviewers describing each step taken in eQuest.  We 
got the following review comment:
“The simulation software used is not capable of modeling VRF systems. The 
project team has not provided information describing  how the VRF systems 
performance has been modeled to reflect the actual design. Please provide a 
narrative and any supporting documentation demonstrating that the VRF system 
characteristics have accurately modeled.”
 
Has anyone had any similar issue regarding a LEED project?  After reading their 
comment, it seems that they might have overlooked our explanation, or maybe it 
was just not enough.  Any ideas? Does LEED accepts this approximation?   Thank 
you very much!
