<div>
<p class="MsoNormal">I am working on a hospital building project which uses existing heat pump at site for service water heating.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The issue is arising in modeling baseline hot water system, which as per ASHRAE 90.1-2013 Table G3.1.1-2 is specified as gas storage water heater for hospital building type. The gas utility rates will not be available for the project since
no gas heating system is used at site.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I want to confirm whether identical system as proposed case can be considered in baseline model as the energy cost savings will need to be compared with existing heat pump at site.<o:p></o:p></p>
