am working on a project that has energy savings on the domestic water heater for
the service water heating due to low flow sinks and lavs. We have been asked to
provide calculations to justify the energy savings on the energy model. The
spreadsheet I have attached shows the calculation proving our savings however I
am having a hard time connecting how eQuest models this compared to the
spreadsheet along with matching the energy consumption values from eQuest and
the spreadsheet. <o:p></o:p></span></p>
