White City


“An area of west London that has been dominated by the sprawling former headquarters of the BBC for decades will be transformed almost beyond recognition within the next few years — providing 6,000 new homes … and establishing a new creative district to rival Soho.” – Mark Bridge. The Times.

Key Challenges

  • Sufficiently remove condensation risks from the light steel frame system
  • Confirm success through graphic and numerical reports
  • Accurately calculate the bracket effect (Chi-value) for the rainscreen

The Brief

  • Calculate screen cladding U-value
  • Perform a comprehensive condensation risk assessment
  • Calculate complex 3D bracket Chi value

Our Approach

We first modelled a spread of indicative junctions, particularly those that show a greater chance of internal condensation risk
The numerical thermal modelling showed a risk within the steel frame system


With close discussion with our client we were able to run variations of design to remove the risk of interstitial condensation
