! Basic file description:  Basic test for EnergyPlus.  Resistive Walls.  Regular (no ground contact) floor.
!                          Regular roof.  No Windows.
!
! Highlights:              Very basic test to see that EnergyPlus "works".
!
!
! Simulation Location/Run: DENVER_STAPLETON_CO_USA_WMO_724690, 2 design days, 1 run period,
!                          Run Control executes two design days (see RUN PERIOD object)
!
! Location:                Denver, CO
!
! Design Days:             DENVER_STAPLETON_CO_USA Annual Heating 99%, MaxDB=-16°C
!                          DENVER_STAPLETON_CO_USA Annual Cooling (DB=>MWB) 1%, MaxDB=32.6°C MWB=15.5°C
!
! Run Period (Weather File): Full Annual Simulation, DENVER_STAPLETON_CO_USA_WMO_724690
!
! Run Control:             No zone or system sizing, design day run control (no weather file simulation)
!
