    <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>
        <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><br>
