What are the pros and cons of VURB?

VURB enables flexible, cost-effective compliance for complex designs,. However, it requires detailed modelling, making it potentially more expensive than DTS.

Short answer

VURB is powerful for custom projects but needs advanced modelling and can cost more upfront than standard methods.

Full answer

Cons: It requires precise 3D energy modelling, which increases assessor effort and cost compared with simpler NatHERS or DTS methods.

Why this matters

For high-end, customised or ambitious projects, the upfront cost of VURB modelling is often offset by long-term gains in build costs, performance and compliance confidence.
