[Equest-users] How to model HP with supplemental heat?

[Karen Walkerman]

Create hourly results which report the hourly supplemental heat for the
building (or for each unit).  You can also include any other variables you
think you need, such as outdoor air temperature and return air temperature.
 Use a spreadsheet program to calculate the hourly part load, efficiency and
energy use of an equivalent gas system.  Then add up the hourly gas use.

To add variables to the hourly results output, go to Project&Site.  Hourly
results are under Simulation Output.

To view the hourly report, go to File --> Export Hourly Results.
