Revisions

  • May 24, 2022, by Michael Wetter:
    Set air pressure to be the same pressure as is recorded in the weather data file. This changes the annual cooling energy for Case 900 by about 4%.
    This is for #3005.
  • May 12, 2022, by Jianjun Hu:
    Changed the floor to be raised floor, disabled linearize the emissive power, changed weather data and adjusted infiltration rate from 0.5 ACH to 0.414 ACH for the altitude.
    This is for #3005.
  • January 21, 2020, by Michael Wetter:
    Changed calculation of time averaged values to use Buildings.Controls.OBC.CDL.Reals.MovingMean because this does not trigger a time event every hour.
    This is for issue 1714.
  • October 29, 2016, by Michael Wetter:
    Placed a capacity at the room-facing surface to reduce the dimension of the nonlinear system of equations, which generally decreases computing time.
    Removed the pressure drop element which is not needed.
    Linearized the radiative heat transfer, which is the default in the library, and avoids a large nonlinear system of equations.
    This is for issue 565.
  • December 22, 2014 by Michael Wetter:
    Removed Modelica.Fluid.System to address issue #311.
  • October 9, 2013, by Michael Wetter:
    Implemented soil properties using a record so that TSol and TLiq are assigned. This avoids an error when the model is checked in the pedantic mode.
  • July 15, 2012, by Michael Wetter:
    Added reference results. Changed implementation to make this model the base class for all BESTEST cases. Added computation of hourly and annual averaged room air temperature.
  • October 6, 2011, by Michael Wetter:
    First implementation.
