Zone Reheat Delta-T

eQUEST users,

I am modeling a simple 9 story office building in v3.63. The system type is
VAV w/ HW Reheat. One Fan system per floor.

With a 20F Zone Reheat Delta-T the Annual Energy Consumption is 38% higher
than it is with a 30F Zone Reheat Delta-T.

This is not intuitive to me why the energy use greatly increases with a
lower zone reheat Delta-T.

Thanks for any help,

Dennis Hunt
