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.</span></font><o:p></o:p></p>

Is it possible to model swimming pool in Energy+? I could not find the way to
