IDA ICE 4.7 changelog

New in ICE 4.7 (rel. to ICE 4.6.2)

Enhancements

  • New version of ESBO
  • The climate data is adjusted to compensate the difference between
    a) hourly mean values and instanceous values
    b) longitudes of location and weather station
  • For detailed windows with glazing without integrated shading,
    a shading layer layer may be added either on outer or on the
    inner side of the window
  • In custom control macros, the access to parameters of controlled
    device made easier (no script required)
  • Mapping IFC spaces to zone templates
  • Converting all IFC spaces to zones
  • Autosave
  • Saving results of multiple simulations
  • Redesigned page "Results"
  • Support light sensor on the outer side of window
  • Using monthly weather data (from ASHRAE 2013 Fundamentals)
  • New cooling load (with multiple simulations and monthly weather data)
  • Automatically download missing climate data
  • Possible to remove tanks in ESBO (modelled as small tanks).
    The default model is without tanks.
  • Radiance daylight calculation and visualization
  • The shade from window recess is treated as semitransparent - to
    compensate the reflection that is ignored
  • Set 2D views in 3D: front, back, top, bottom, left, right
  • Visualization and animation of integrated and external shades with new geometries
  • Support left and top margins for any area pane (was only for floor plan)
  • The default simulating date for cooling/heating simulation is now recalculated
    after change of location.
  • Import of IFC files with extra information from Simplebim:
    1) transparent panels in curtain walls imports as windows in walls
    2) explicit given shape of a building storey imports as a building body
    3) construction type of a curtain wall imports as a construction type of a wall
    4) a type of a curtain wall (internal or external) imports as the type of the wall
  • Possibility to change building location and orientation at advanced level.
    The shading is also recalculated after change of simulation time.
