v3.0 [Jun 20, 2011]
E : Updated for the latest v19 of the IGDB glazing database. E : Fix for natural ventilation data showing up under DHW on the HVAC tab under certain circumstances. E : Increased enthalpy limits for mixed mode control. Daylighting: Improved error control in daylighting. E : Boilers and chillers added to HVAC templates and unitary performance data correctly labelled.
E+: Fix for bug where airflow through holes is reported at the surface level instead of hole level in recent versions having knock on effect on CFD boundary condition imports. E+: New Unitary DX cooling coil option for AHUs with additional option for single speed or 2 stage with humidity control. E+: Fix for Unitary heating and cooling performance data not always displayed on HVAC tab in model data. E+: Fixes and improvements for cooling tower dialog. E+: Mixed mode natural ventilation option now only shown for calculated natural ventilation and compact HVAC. Daylighting: Can now handle very large contour map data sets. Daylighting: Improved handling of merged zones. Daylighting: Fix for crash in some roof zones. Daylighting: New option to include/exclude other buildings from Radiance simulation. CFD: Fix for bug where CFD surface patches can transform into other opening types in certain cases. CFD: Fix for component block CFD boundary conditions being missed when contained in merged child zones. All: Fix for lost custom openings when drawing partitions. All: Fix for bug preventing construction lines from being deleted at surface level. All: Fix for sub-surface texture bug.
