[Equest-users] Team eQUEST: Lowdown Showdown Report

Nick, Aaron, Cara, Pasha, Chris,

I'd like to add my congratulations to those of others for your great 
work at the Lowdown Showdown.  It's very impressive what your team was 
able to achieve on a strictly voluntary basis, and shows how much 
innovative modeling can be done with eQUEST/DOE-2 .

For my personal curiosity, I'd like to ask the team:
(1) how much of your work was done using eQUEST "out of the box", and 
how much of it tweaking the underlying DOE-2.2 engine? This question 
applies mostly to the modeling of low-energy HVAC strategies, esp. the 
solar chimneys.
(2) what was the motivation to use Radiance to calculate daylighting 
instead of the native daylighting capabilities in DOE-2?  (this is not 
meant as a challenge - I simply have never looked into the 
strengths/weaknesses of the DOE-2 daylighting calculation)
(3) great to see the multi-variant analysis of 60,000 runs, especially 
the colorful 3-D surface plot :-)   What were the two axes being 
plotted?  There are those who dismiss slow runtimes as just an 
annoyance, but my experience is that fast runtimes open up whole new 
ways of analysis.  When DOE-2 runtimes got down to a few seconds, I 
started doing a lot more experimental design.

I also suggest that you send your post to BLDG-SIM to get more 
distribution, especially among readers less familiar with eQUEST.

Once again, congrats!

Joe
