ICE 4.0 Build 5 released 2010-10-20

New in ICE 4 Build 5
====================

* Added two new reports: Thermal comfort according to EN-15251,
  with and without cooling.
  The new reports are switched off by default

* Supported "hanging" walls (i.e. not adjacent to the floor,
  or only partially adjacent to a floor).

  Such walls may appear in a zone that intercects multiple
  parts of the building body.

  A zone still may not have different floor levels in different
  parts of the building body.

* In the zones, rhe roof may now intersect the floor.

* Copy an object (or a field showing the object) and paste it
  to a script window to insert a reference to the object

* The user-defined extensions of ICE are now installed either in
  the user's or in the common folder (and not in program folder
  as before)

* In IFC import:
  A new way to calculate external corners
  More precise position of a wall
  Warnings about space and section intersections

* Default energy meter for electric floor heating is now
  "Electric heating".
  The field "Energy meter" of the electric floor heating made
  available at standard level.

* Default energy meter for electric radiator changed from the
  zone's default equipment meter to "Electric heating".
  The electric radiators in the existing user's system will
  keep their energy meter, but they will be not marked as
  [default].

* The toolbar is replaced with a more modern one 

* Added new system parameter
    syspars.CD_lo = 0.65 "Large opening discharge coefficient".
  Mapped to parameter CD in models CELVO, MLVO, CELHO, MLHO.

* (build 5.01) Supported floor temperature control for electric
  heated floor

* (build 5.01) Supported computed x-range for diagrams

* (build 5.02) Added transmission through doors to the zone
  energy report (Envelope transmission table)

* (build 5.02) More reliable roof import from IFC

* (build 5.05) Reordering zones by clicking Alt+Up and Alt+Down
  in the list of the zones in the main view.

Changes in models and functions called from models
=================

* CEDetZon   Dewpoint temperature in MiscMeasure computed using
  CESimZon   XHum instead of XHumLoc.

* TAIRSAT    Fixed initial guess for iterations

* RELHUM     Fixed Jacobian

* OnOffwDelay  New model

* CLIMATE    Added output variables WindVel2 and WindDir2

* A2A_AC     The model AirHeetPump renamed to A2A_AC (the old
             name was wrong)


--- in build 5.01 -----

* SIMCHIL    Corrected bug in using performance curves


--- in build 5.02 -----

* SIMCHIL    Removed event

* CEBEAM     Rewritten exponent => more robust for small flows.
  CESFBEAM

* cebeam     Min liquid flow changed to 1e-8
  Cesfbeam
  pmtMultiT
  pmtMultiM
  PMTCONTR
  HCSIMCTR
  FLHEAT
  cewathet
  CECOLPNL
  CCSIMCTR

--- in build 5.05 -----

  CEFAN      Warning if air flow is bigger than rated air flow

Fixed bugs
==========

* Inserting HC panel in zone did not work.

* If a value of a parameter was mapped to a component of an resource,
  this value was changed when editing the resource even if the mapping
  is broken. Examples of such parameters: setpoints in control macros
  that are mapped to components of "Setpoint collection" resource.

* The 3D view was not updated after changing default constructions

* IFC import: Fixed bug in the section intersection check

* Fixed cases when a wrong property page is shown

* Schedules in database with unspecified type of the output signal was
  not available in "Load from database" dialoog. 

* Fixed error in table "Envelope transmission" (transmission through
  roof during heating/cooling period and the rest of time).
  For old systems, the error is fixed when opening the system, but
  with limited accuracy (rounded to 100 kWh instead of 0.1 kWh).

* Fixed bug in the import of the roof from IFC

* Fixed using variable setpoints with user-defined control macros

* The parameter "Performance" in chiller and boiler did not work

* Fixed some bugs in online documentation

* (build 5.01) Fixed the unit for CO2 emission in "Energy meter"
  form. It was written mg/kWh, but the program assumed g/kWh.

* (build 5.01) Fixed comparing binding of variables in diff.
  False differences was reported in old versions.

* (build 5.01) Fixed heating/coolin floor. The heating worked
  incorrectly with "thermostat" control and variable setpoints.

* (build 5.05) Fixed bug in copying object of object with user-
  defined type to other system (the type was not copied)

* (build 5.05) In version project, the system marked with "do
  not simulate" are now not included in the report.

* (build 5.05) It was allowed to add extra VAV AHU to zone. This
  was not supported by the program. Now only CAV AHU may be added.
