Dusko,
That's also the methodology I followed for a recent project in eQuest.
You can find an equation for the evaporation rate in the ASHRAE
Applications Handbook. Another source is
http://www.rlmartin.com/rspec/whatis/index.html.
Hope this helps.

I cannot comment on Energy+. However, as far as eQUEST, I've modeled a
natatorium (indoor pool) including the latent load. In one of the
ASHRAE books, there's a methodology for determining the latent loads of
a pool as a function of activity, water temperature, and I believe a few
other factors. I ran through these calculations and inputted this load
into the "Internal Energy Sources" under the Equipment internal gains
tab. I created a schedule based on when the proposed pool cover would
be off (pool in use), and called it a "process" load. I believe I set
the Latent HG ratio to 1.0 and Sensible to 0.
The results of my model seemed to be reasonable.
Maybe with this methodology, it might allow you figure something out
with Energy+; otherwise, eQUEST may be your best, closest approximation,
for this project.

Hi,
Is it possible to model swimming pool in Energy+? I could not find the
way to model latent loads due to water evaporation
Thanks
