Simulation of homes has been traditionally carried out using the Chenath/NatHERS software, most frequently for compliance purposes. The DesignBuilder (DB) software suite provides additional functionality for analysing the design of thermally comfortable and energy-efficient homes. The DB graphical user interface (GUI) allows for building geometry input from CAD files, rendering of sunpath and shadow diagrams, daylight analysis, prediction of the impact of passive solar and natural ventilation strategies on space thermal comfort, as well as prediction of annual energy use for heating and cooling.
Australia’s National Construction Code (NCC) allows for energy simulation of buildings by comparing a Proposed Design against a Reference Design. Long used to test commercial building compliance using Section JV3 of Volume One, this compliance path is also available for detached housing under Section 2.6 of Volume Two via the VURB (verification using a reference building) method.
Typically, Day 1 of the training workshop focuses on residential buildings, concentrating on the use of DesignBuilder to analyse house designs. Day 2 normally covers Section J compliance for commercial buildings using the JV3 Alternate verification using a reference building method (Volume One). Cooling load calculations using the ASHRAE Heat Balance method, and modelling of detailed HVAC systems will be addressed. New DesignBuilder features and the use of computational fluid dynamics (CFD) will be demonstrated.

All new DesignBuilder version 6 licences and upgrades come with one (1) complimentary hour of email or phone support. A range of online support resources are listed below:
- Introductory video tutorials
- Webinars for specific topics
- Online Help (V6)
- Knowledge base, FAQ, and Support Desk
- Hardware and operating system requirements
Additional, specialised, project-specific support may be purchased in blocks of time. A typical support request might use 20 minutes in which case a 60-minute support block would cover three incidents.
