color=#0000ff size=2>We just completed a project with KONE's high efficiency
elevator system. We assumed hydraulic to be the baseline, and the KONE
traction elevators to be the EEM. KONE has their own software where they
ran the analysis for us for both system types. They provided the baseline
and EEM energy usuage (kW) of both elevator systems. We plugged these
values into eQUEST as a direct load to the electric utility meter and used
the elevator default schedule in the eQUEST library.

<DIV>I was also just in the process of developing a calculation. I sent an email
to Otis Elevator inquiring if they had worked through this already, but recieved
no reply. There is an interesting ACEEE paper on elevator energy
consumption and efficiency at h <A

<DIV>I would be interested to see how anyone has calculated savings or
collaboration if you are working through it now.</DIV>

have submitted a LEED-CS v2.0 project for review where we took credit<BR>for
elevator efficiency (I haven't received any comments back yet, so I <BR>don't
know if they will go for it). That being said, I also review LEED<BR>EAc1
submissions, on behalf of the USGBC, and would likely allow such an<BR>ECM as
long as the calculation methodology was clearly laid out and well
<BR>supported.<BR><BR>I used manufacturer data (horsepower ratings) for the
traction elevator<BR>and compared to a "typical" hydraulic elevator. I
couldn't find any<BR>reputable source to create a partial load schedule for
the motor, so I <BR>applied the appropriate elevator schedule (in this case it
was an<BR>office) from the schedule tables that can be found at the end of
the<BR>Appendix G section of the ASHRAE 90.1-2004 User's Manual. I also put
the <BR>elevators on their own electric meter so that I could easily sort
out<BR>that data. It certainly isn't a highly-refined calculation,
but<BR>shouldn't be any worse than the estimate you would have to make
to<BR>account for elevator energy in the first place.<BR><BR>I've heard there
are some programs that specifically model elevator<BR>systems (more for
optimizing usage than energy), but I haven't used any<BR>of them. Anybody know
if these are a more accurate way to estimate <BR>elevator energy
usage?<BR><BR>I would also recommend reading some of the papers published by
Lutfi<BR>Al-Sharif (an engineer or professor from the UK, I believe), who is
one<BR>of the foremost experts in elevator energy usage, as far as I can tell.
