Version Features

DesignBuilder v3 introduces some important new features as well as widespread consolidation of existing functionality.

Version 3.2 features:

  • EnergyPlus v7.2
  • Detailed HVAC template wizard allows fully connected systems to be loaded to the model
  • More ASHRAE 90.1 and LEED options including Appendix G constructions and outline baseline HVAC systems
  • Improved Simple HVAC simulations with options for humidity control, heat recovery and economiser as well as faster autosizing
  • Change-over Mixed mode now available for all HVAC and Natural ventilation model options
  • Simulate phase change materials (PCM) in detail
  • Fanger PMV control
  • Constant CoP chiller
  • More flexible heated floors and chilled ceilings
  • EnergyPlus database of 110 air-cooled chillers added to existing water-cooled chillers - total count of 274 chillers
  • Latest v28 IGDB glass database and option to import Glass data from WINDOW6 files directly into DesignBuilder Pane dialog
  • Custom crack templates can be defined  for Calculated natural ventilation
  • Infiltration can be scheduled
  • Many fixes and improvements, especially in Detailed HVAC
  • Approved by Scottish Government for EPCs and Section 6 reports but not by DCLG for E&W EPCs and Part-L
  •     
    Version 3.0 features:
  • Detailed HVAC with access to a wide range of EnergyPlus HVAC systems through an easy to use diagrammatic interface.
  • Radiance daylighting calculations with integrated graphical daylight distribution contour plots and reports for LEED, BREEAM and Green Star.
  • EnergyPlus v7.0 with significant speed improvements over previous versions.
  • SBEM v4.1.d
  • Sunpath diagram option on the Visualisation screen
  • Various improvements in the BIM import and the modeller
  • v20 of the International Glazing Database (IGDB).
  • Revit plugin which speeds up the data transfer process from Revit to DesignBuilder. Supports 32-bit and 64-bit Revit 2011, 2012 and 2013. .

Version 2.4 features:

  • Compact HVAC now provides access to EnergyPlus boiler, chiller and fan part-load performance characteristics
  • DesignBuilder EnergyPlus IDF output is now much more readable through use of user-defined zone names instead of numeric references used previously
  • In Compact HVAC mode DesignBuilder outputs EnergyPlus-calculated plant energy consumption so DesignBuilder energy consumption outputs now agree with reports obtained directly from EnergyPlus
  • Uses SBEM v4.1 for 2010 UK and Ireland Part-L and EPCs

Version 2.3 features:

  • Uses EnergyPlus v6 which runs noticeably faster than previous versions
  • Simple glazing where glazing systems can be defined using basic manufacturers data (including or excluding frame)
  • Improvements in CFD robustness
  • Many EnergyPlus summary outputs such as ABUPS reports can be generated and viewed from within DesignBuilder
  • EnergyPlus daylight factor reports
  • UK and Ireland SBEM 3.5.a approved
  • Supports pay as you go licensing for SBEM EPC users
  • Portuguese IEE module
  • Ongoing improvements to gbXML import including full support for imported shading surfaces
  • Embodied carbon outputs

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
  • 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:

  • 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.
