JV3 Reports and Assessments

JV3 Alternative Solution is an alternative method of compliance.

JV3 involves a 3D computer simulation to demonstrate that the annual energy consumption of the proposed building is equivalent or better than the annual energy consumption of a reference building which complies with the Part J DTS provisions.

There are many benefits to JV3 assessments.

This is mainly derived from the ability to consider the building as a whole, instead of individual components in isolation.

This provides much greater design flexibility and the ability to “trade off” between different building elements, often resulting in more cost effective building specifications such as increasing insulation rather than upgrading to double glazing.
