IDA ICE 4.6 changelog

New in ICE 4.6 (rel. to ICE 4.5.1)

  • Forum
  • Registration
  • Changed IDA license handling menu to only include update license
  • Replaced sample IFC file "SmallOffice_d_IFC2x3.ifc"
  • Added documentation to supervisory control
  • The applets used in Room Wisard are now signed (to avoid blocking)
  • MINMAX replaced with MINMAXD in heating and cooling fan coil macros
    and in VAV_T+CO2 control macro.
  • Possibility to show a diagram with same variables from all (or selected) zones
    Available by right clicking the variable in legend
  • Added signal CO2vol to zone proxy and zone sensor (unit = ppm (vol))
  • Added duration of cooling and heating period to the zone energy report
  • Checking t > g for windows with shades
  • Show list of references to meters, AHU, control macros (as was for resources)
  • Add sill height columns to the table of windows
  • Possibility to shift IFC model
  • Added capacity parameter to heat exchanger form (default: unknown)
  • Decoupling: added TQ connection between decoupled half-walls

[Beta 2]

  • Do not block modeler when waiting output from solver
  • Zone AHU may be connected with plant from "AHU" side
  • Support adding fileds to forms (by ICE extensions or by scripts)
  • Removed decoupling: it will be an extension
  • New option for leaks: given flow

[Beta 3]

  • The windows inserted in [vertical] facades are now shown in floor plan

[Beta 5]

  • Added Cd factor for openings (incl openable windows)
  • Added opening size for openable windows
  • New version of SketchUp reader to support SketchUp 2013 files
  • Zoom selected object in 3D view
  • The selection of connected facade changed to hierarchical menu
    (building part -> fasade/roof [-> roof part])
  • Display coordinates in status bar when drawing a zone

[Beta 6]

  • For detailed windows:
    Calculating glazing properties with and without shading.
    The result may be stored as "simple" glass construction and shading.

[Beta 7]

  • Zooming 3D view with mouse wheel
  • More options for duration diagram
    Display "over" and "under" times for.

[Beta 8]

  • Carpet plot
  • Custom time schedules (e.g. from source files) may be defined in
    control macros
  • Added a column with sensible cooling load

[Beta 9]

  • New ICE site (Download & Info Center).
    Redesign of the help menu and process guide.
  • Additional shading objects (fixed shade, fixed fins) may be inserted into face in 3D view
  • Allow user-defined signals in AHU and Plant proxy
  • Logging and animation of window integrated shading control

[Beta 10]

  • Export systems to IDA Viewer (not openable in IDA Modeler)

[Beta 11-15]

  • Using "Mode" dialog to insert features in floor plan
    (double-click feature in palette to open dialog; click multiple place to insert; Ok button to exit mode)
  • Carpet plot
  • Shading objects (without control) may be insertion into faces (in 3D view)
  • Shading transparency [without diffusion and reflection]
  • Fixed logging local AHUS and fan coils to Systems report
  • For detailed window: Calculate parameters at reference conditions
    with possibility to save results as simple glazing and shading
  • More detailed categories of enclosing elements in the table "Zone totals"
    and in the input data report
  • New fan coil: CAV. Removed "Undefined" fan coil.
  • Solar panel: added temperature limit

[Beta 16]

  • Shading transparency [without diffusion and reflection] also for imported objects
  • Improved animation controls

Changes in models and functions called from models

  • TankStrat Shunt not used in very first IV.
  • SyntClim Fixed calculation of RelHum
  • CEDETZON New option for MiscMeasure: XCO2Vol
    CESIMZON
  • CESIMZON Allow negative CO2FSrcEquip
  • MLEAK New option: given flow
  • WitType Excluded error when not connected with DetWin model
  • StInjCtr Defined default binding for input signals
  • CELVO Fixed time constant for caclulation density
    CELHO (default value = 30s)
    MLVO
    MLHO
  • DETWIN Fixed expression for Nu[i], was SIN(degrees)

Fixed bugs

  • Internal shading of floors did not work properly when compass or building is rotated
  • Bug in "paste here" building body
  • The local cooling and heating was reported twice in the diagram "zone energy sources"
  • Fixed some license bugs
  • Fixed bug in generating facades form IFC
  • Fixed logging of output signal from schedule - did not work with "always_on" and
    "always_off" schedules
  • Fixed "Call of undefined ASK-USER-FOR-CHOICE-FROM-LIST"
  • Fixed symbol of interface reference in control macro (was lost in version project)
  • Fixed changing occupant type in ESBO
  • Fixed copying plot line of operative temperature
  • Fixed crash in calc-part-sizes
  • Fuxed clothing in design load dialog (did not work)
  • Avoid crash when importing IFC file with too complicated roof
  • Fixed reloading resources from DB - in case when the new resources use other
    DB entities that are not yet loaded (e.g., new version of wall construction
    requires loaning new materials)
  • Fixed moving building body relative to the ground level (for editable body only)
  • Disabled zero design air flow for active beams (unless the power is also zero)

[Beta 2]

  • Fixed comfort report for >1 year sumulation
