To undertake a JV3 assessment, you need to model your building in a 3D manner. After that, you must introduce your building fabric and shading features to the model and implement specific modelling parameters. These parameters and profiles for a JV3 assessment are detailed in NCC Vol 1.0, Section J, Specification JVb and Specification JVc. ESD consultant is not able to change these parameters but can offer more realistic hourly profiles for the operation and services used in the proposed building. Also, JV3 assessment demands a thermal comfort modelling and you must claim that your proposed solution doesn’t affect the occupant’s comfort in the building.
