Version Features

DesignBuilder v.2.2 introduces some important new features as well as widespread consolidation of existing functionality.

Version 2.2 features:

  • UK and Ireland SBEM 3.5.a approved
  • CFD age of air and LMA data
  • CFD numerical output
  • Boolean geometry (part 1)
  • Zone merging dialog means that use of holes to merge zones is not required any more
  • Fan energy consumption can be modelled more accurately in Simple HVAC
  • Exterior lighting energy modelling
  • Lighting gains can be defined as W/m2/100 lux avoiding modelling errors that can occur with the other 'W/m2' lighting option when illuminance requirement is changed
  • LIDER export works under Windows XP for Spanish certification

Version 2.1 features:

  • 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 gives 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.
