JV3 Assessment
Performance-based energy modelling that unlocks design flexibility beyond Deemed-to-Satisfy.
JV3 (now J1V3) is the verification method that gives architects room to move. We build a 3D energy model of your proposed building and a compliant reference building, then demonstrate yours performs as well or better. It is the pathway that rescues ambitious facades from DTS limits.
When you need it
Used when a commercial design does not fit the Deemed-to-Satisfy path, or where glazing and facade freedom is needed. Modelled against a reference building.

- JV3 / J1V3 verification report
- 3D energy model of proposed and reference buildings
