[EnergyPlus_Support] Heating Design and simulation

["t.t111ir" <t.t111ir@xxxxxxxxx>]

Dear team ,

Zone  Mean Air temperature : is the average temperature of the air temperature at the system time step .

zone/sys Air temperature : this is very similar to the zone mean air temperature but this temperature is also available at the detailed system timestep.

i dnt undrestand the diffrence between two output : zone/sys air temperature and zone mean air temperature 

i have a question about heating design and simulation process .

at design stage , energy plus do design for the coldest day of winter and use heating setpoint temperature then it detemine the capacity of the building ,

but for simulationg this building for another day it uses thermostatic setpoint temperature and then it determine how much enrgy is actualy used by plant ?

i want to know   summary of predictor and corrector procedure , in engineeringrefrence.pdf (energyplus document):

using equation (2) , an estimate is made of the air energy required to balance the eqution with the zone air temperature equal to the setpoint temperature .
with that quantity as a demand, the air system  is simulated to detemine its actual supply capability at the time of the simulation. this will include a plant simulation if necessary.
the actaul air system capability is used in equation 10 to calculate resulting air temperature.

it means at first it detemine the capacity of building with heating setpoint and after that with this , it simulate the energy consumption of buildin according to themostat heating set point , and then with that consumption it calculate air temperature ??

and also i want to know the temperature that people sens is operative temperature ?

thanks in advance
