Dear All,

Currently, I am trying to model *water side economizer* for a high rise
building located in moderate climate. After going through help menu i
realized that software can address modeling this partially with some
reasonable accuracy. The major limitation is that the
program assumes a water-side economizer is used in an "all or nothing"
mode. If the water-side economizer can handle the entire cooling load, then
it will be used. Otherwise, the loop will use its other chillers
. Does anyone mind sharing their experience in modeling water side
economizer with success and acceptable accuracy.

Any insight would be highly appreciated.

Thanks in advance,
