Upcoming training

UPDATE: there was an issue with the registration form which was on this page previously, so if you did register your interest earlier for the training, please do e-mail us again directly at  ; we apologise for any inconvenience.

Owing to circumstances beyond our control, DesignBuilder Software Australia has had to change its upcoming software training.  The Perth, Western Australia workshop scheduled for 1, 2 and 3 April 2019 will not take place.  Instead, we are running the same training in Sydney on Monday-Wednesday, 13-15 May.  Details of the venue will be announced shortly.

Please email us at for further information.  

Day 1:  Introduction to building simulation and the DesignBuilder software system (compulsory for all participants).

Day 2:  Compliance for NCC Vol Two residential Class 1 buildings via VURB; daylighting analysis and comfort for passive-solar houses. Naturally ventilated houses will also be covered.

Day 3:  Compliance for NCC Vol One Section-J for non-residential buildings via JV3; HVAC cooling load calculations; Detailed HVAC system modelling and CFD will be addressed .

All participants have to attend Day 1; they may attend either Day 2 (residential buildings) or Day 3 (commercial buildings), or they may attend all 3 days.

Simulation for 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.

Day 2 of the training workshop will be focused on Residential buildings, concentrating on the use of DesignBuilder to analyse house designs.  Day 3 will consider Section J compliance for commercial buildings using the JV3 Alternate verification using a reference building method (Vol One).  Cooling load calculations using the ASHRAE Heat Balance (HB) method, and modelling of detailed HVAC systems will also be addressed.  The use of CFD will also be demonstrated.



All new DesignBuilder version 6 licences and upgrades come with one (1) complimentary hour of email or phone support.  Extensive free support is also available from our web-based Support Desk, part of a wide range of free, online support resources:

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.
