[Equest-users] Minimum Efficiency of VTAC System

[Elizabeth Gillmor via Equest-users]

The answer depends on your goal:

If you are looking for mandatory efficiency requirements for code
compliance, you would compare to the SPVHP numbers.

For Energy Cost Budget method or Appendix G analysis, you would use the
PTHP as your baseline system type, so you would use PTHP numbers as your
baseline efficiency.
Hope that helps!  Cheers,
Elizabeth
