DesignBuilder v.2.1 has some important new features as well as widespread consolidation of existing functionality. The most significant improvements in Version 2.1 are:
- Latest EnergyPlus v4
- Substantial improvements and stabilisation in CFD and related documentation
- New site licensing system using network license server
- Latent gains can be specified for equipment
- Improvements in gbXML import
- German language interface option
- LIDER export for Spanish certification (free for all EnergyPlus license holders)
Version 2.0 features:
- 3-D Computational Fluid Dynamics (CFD) allows you to analyse the airflow and comfort distribution inside and outside of buildings. A link to EnergyPlus simulations provides simulated surface temperatures and natural ventilation flow rates as boundary conditons to the CFD simulations.
- CAD BIM import from Revit, ArchiCAD, Microstation and other CAD software supporting the gbXML interoperability standard.
- Mixed mode natural ventilation to ensure HVAC and natural ventilation do not ocur simultaneously.
- New HVAC modelling options include humidity control and baseboard heaters (convective and radiant). Further significant improvements in HVAC will be phased in over v.2 development cycle.
- EnergyPlus 3.1.
- Option to edit data at opening level allowing different window and door types on a single surface
- Assemblies for modelling CFD objects and solar shading systems.
- More flexibility in the cutting tool in particular blocks can now be cut flush with other surfaces of the block
- Option to include/exclude zones from the analysis useful for modelling certain parts of a building only.
- More configurable results display give better control over simulation output and an option to save result templates
- Display of simulation results for individual surfaces and openings.
- Green roofs including irrigation control.
- Option for radiosity-based DElight daylight simulation integrated within EnergyPlus thermal simulation
- Parametric cooling design calculations and simulations.
- SBEM 3.4.a for UK and Ireland. This is required for lodging EPCs from 10 May 2009 onwards.
- Portuguese IEE certification calculations.
