J1V3 Assessments Australia
Performance-Based Energy Modelling for Complex Development Projects
Supporting projects throughout New South Wales, Victoria and Queensland with integrated energy efficiency and development expertise.
Senica provides J1V3 Assessments and advanced energy modelling services for commercial, mixed-use and complex developments throughout Australia.
We help project teams evaluate performance-based energy compliance pathways that deliver flexibility, efficiency and high-performing building outcomes.

What is a J1V3 Assessment?
A J1V3 Assessment is a performance-based energy modelling methodology used to demonstrate compliance with applicable building energy efficiency requirements..
Unlike prescriptive pathways, J1V3 assessments evaluate how a building performs as a whole by comparing the proposed design against a compliant reference model.
This allows project teams to assess alternative design solutions while achieving energy performance objectives.
When Is J1V3 Appropriate?
J1V3 assessments are commonly used where projects involve complex architectural design, extensive glazing, innovative building systems or performance-based design approaches.
The methodology provides greater flexibility than prescriptive compliance pathways and allows project teams to optimise building performance while responding to architectural and operational objectives.

Benefits of the J1V3 Pathway
