<div>Dear Sebastian,<br>
<br>
I start with kW/ton ratings at AHRI conditions from the manufacturer. Those are good inputs into the software. I use Energy Pro, but I believe most software can take that as input.<br>
<br>
It is theoretically possible to estimate performance with evaporative pre-coolers if you have reliable effectiveness and chiller data.
<br>
<br>
Most programs will allow VFD or multi-speed pumps as well.<br>

<div dir="ltr">Hi all,
<div><br>
</div>
<div>I'm trying to assess possible energy savings from improving different areas of a chiller plant (cooling towers, adding free cooling, VFDs, controls). Currently all the information I have is a snapshot of the chiller plant performance at 2pm every day of
the summer.</div>
<div><br>
</div>
<div>Is there a simple way to evaluate kWh saved? If modelling is the best option which software is the best for this kind of analysis?</div>

</div>
<div>Thanks for any help,</div>
