Good morning,

I am working on a project that is using Dedicated Outdoor Air Systems for
ventilation.
These units are designed to supply neutral (~70-75F) temperature air to the
building.
Heating is provided by heat pumps, but they have auxiliary natural gas
heating to supplement the heat pump heating.

Would my heating fuel be considered "Hybrid" in this case or can I consider
it "electric"? This is for a LEED project, so I am hoping someone has
experience with this type of system for LEED.

Thank you,
