Re: [EnergyPlus_Support] Re: Sizing according to ASHRAE 90.1

No, it means that if the reheat coils are operating during the cooling 
season, which they sometimes do, that the zone temp will be controlled 
to the thermostat heating set point (20C). If the zones are over-cooled 
and require that the reheat coils turn on, the air temperature in the 
supply duct after the reheat coils will be whatever it needs to be to 
bring the zone temp back up to to 20C.

Run a simulation and review the zone temp when the reheat coils are 
active. The zone temp should be maintained at the zone thermostat 
heating set point temperature. You can then look at the supply air temp 
leaving the reheat coil and see what temperature that node is.
