IDA ICE 4.1 changelog

ICE 4.1 Build 0 and 1 released 2011-01-25

New in ICE 4.1 Build 0 and 1

• Undo and redo

• Import of shading objects: added SketchUp format

• The user may reset zones to the current template (from
  zone template menu below floor plan).

• Show the shading layer of detailed window in the list of
  windows (not editable)

• IFC import:
  Improved door and window positions in a walls
  Support for multilevel spaces
  Read correctly circular walls that had been straightened
  Better external corners

• New options for diagrams:
• sorting variables
• multiple stacks in stack bar diagrams
• draw values on stack bar diagram (was only on not-stack)
• choice of position where to draw values
• tooltips and context menu works now with area diagrams and
  with bar chart diagrams
• more options for axes

• New alternative for infiltration units: m3/(h.m3 ext. surf.)

• Colorized code view for NMF/Modelica models

• Visualization of twist and tilt [Build 1: and frame fraction]

• [Build 1] "Refresh" menu rebuilds 3D view of the building

• [Build 1] Added option "Memory limit" to the first page of
  Preferences dialog. Increase the limit in case of "Out of
  memory" message. Decrease the limit if you cannot start
  multiple instances of IDA ICE due to lack of memory.
  Restart IDA ICE after changing memory limit.

• [Build 1.01] Attempt to solve problem with security of the
  communication with Microsoft Office.

Changes in models and functions called from models

• CEDETZON New output variable QLocCond: heat flow from
  CESIMZON condensation on ideal cooling units

• SKYTRACE Fixed bug introduced in 4.0 build 5.

• CCSIM Fixed bug in computation of UAExt. Error message
  if bypass factor is negative.

• DETWIND [build 1] New parameter ctrlDBand
  (=dead band/2, W/m2) in switching mode condition.
  T4 law rewritten.

• A2A_AC [build 1] Some variables renamed
  A2A_HP

Fixed bugs

• Windows in the ceiling explicitly connected to a part of
  complex roof did not work

• More accurate calculation of "number of" when creating zone
  from template (to ensure that the numbers/m2 in the list
  of zone agree with template)

• Fixed problem with copying calculated parameters and
  parameters with wrong mapping

• The small exterior wall that has no external surface
  are now modelled as adiabatic walls (they crashed the old
  version with message "Wrong value AWall = <negative value>)

• The column "Local cooling units" of zone energy report
  included the cold consumed for condensing vapour on ideal
  cooling units. This should not be concidered as sensible
  heat and therefore is now excluded.

This change does not affect the existing reports from old
simulation and the reports that will be produced from
advanced-level systems created in old versions of ICE.

This change affects only the zones with condensation on
the ideal cooling units.

• Fixed calculating adjacency for small zones.

• The double glass facade crashed in case of zero air path
  (except return air path that could be zero). Now any path
  may be zero (but not all).

• Fixed error in calculating ceiling for zones that are
  partially outside of the building (In 4.0 build 5, extra
  ceiling parts was created at the intersection of the
  zone with the building body).

In most cases, we automatically remove such parts from the
building created or edited in old builds. The exception
is the case then there are some features inserted in ceiling
parts.

• Fixed skylight model (did not work in 4.0 build 5)

• Fixed bug in editing undergroung parts of the building

• Fixed bug in saving zone templates (sometimes the changes
  made in new zone templates was not saved)

• The "fans off" option in heating load simulatuin was ignored
  by additional AHU in zones. Now fixed.

• Fixed bug with shading of horizontal windows.

• [build 1] Fixed reflection and emission in opening without
  door (was depenent on door construction)

• [build 1] Fixed bug in ceiling geometry

• [build 1] When creating new control macro, "Cancel" button
  did not work properly. Now fixed.

• [build 1] Fixed calculation of U-values of doors for table
  "Zone totals". In case for door with default construction,
  the wall construction was used instead of the user-defined
  default construction.
  In simulation, it was the same error, but only for always
  closed doors. This error is also fixed.

• [build 1.01] Fixed calculation of SGCH, T, and Tvis of detailed
  vindow in case non-zero diffusion (the bug did not affect
  simulation)

• [build 1.01] Fixed simulation of floor heating/cooling in case
  when the floor heating/cooling unit overlaps with walls on
  the other side of the floor (or ceiling) containing the unit.
