Re: [EnergyPlus_Support] Read variables during a simulation and not only at the end

You can also run shorter simulations to see results more quickly. See 
the RunPeriod object. The run period below is for Jan 1 - Jan 7.

RunPeriod,
  1,        !- Begin Month
  1,        !- Begin Day of Month
  1,        !- End Month
  7,        !- End Day of Month
  Tuesday,  !- Day of Week for Start Day
  Yes,      !- Use Weather File Holidays and Special Days
  Yes,      !- Use Weather File Daylight Saving Period
  No,       !- Apply Weekend Holiday Rule
  Yes,      !- Use Weather File Rain Indicators
  Yes;      !- Use Weather File Snow Indicators

It is always quicker to just run design days while you optimize your 
simulation. See the SimulaitonControl object.

SimulationControl,
  No,       !- Do Zone Sizing Calculation
  No,       !- Do System Sizing Calculation
  No,       !- Do Plant Sizing Calculation
  Yes,      !- Run Simulation for Sizing Periods
  No;       !- Run Simulation for Weather File Run Periods
