What is IES VE and why do you use it?
IES Virtual Environment (IES VE) is one of the world's leading integrated building performance simulation platforms. It allows detailed modelling of thermal, energy, HVAC, lighting and ventilation performance in a single integrated model. We use IES VE because it's accepted by certifiers, councils and rating schemes across Australia, and produces highly accurate simulation results based on real climate data and dynamic thermal analysis.
At what stage of design should building energy modelling be done?
Building Energy modelling adds the most value when done early — at concept or design development stage — when design decisions are still flexible and changes are low-cost. However, we can provide modelling at any stage, including construction documentation for compliance purposes or post-occupancy for performance verification.
Is building energy modelling required for compliance?
It depends on your building type and the compliance pathway chosen. Building Energy modelling is required for J1V3 Section J assessments, NABERS energy ratings and some Green Star credits. For NatHERS residential assessments, NatHERS-accredited software (rather than IES VE) is used. We'll confirm what's required for your specific project.
What building types do you model?
We model a wide range of building types — commercial offices, retail, hotels, mixed-use residential and commercial, educational facilities, healthcare buildings and industrial facilities. Both new buildings and major refurbishments can be modelled.
What information do you need to start?
Architectural drawings (floor plans, elevations, sections), glazing schedule, construction specifications (wall, roof, floor), HVAC design documentation and a site plan with orientation. For early-stage concept modelling, we can work with less detailed information and make reasonable assumptions — refining the model as the design develops.
