Upcoming Training:  Location and Dates

DesignBuilder is running a full training workshop in Sydney over Monday to Wednesday, 13-15 May.  The venue is:

North Sydney Training Centre
Level 2, 80 Mount Street
North Sydney 2060
Ph: 1300 859 892

Please email us at for further information and to book a place at the workshop.

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 .

Participants who are new to DesignBuilder should attend Day 1; they may enrol for either Day 2 (residential buildings) or Day 3 (commercial buildings), or enrol for 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 (Volume One).  Cooling load calculations using the ASHRAE Heat Balance method, and modelling of detailed HVAC systems will also be addressed.  The use of computational fluid dynamics (CFD) will also 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:

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.
