This webinar introduced our recently published Technical Note on fire performance of facades, TN116 Fire performance of facades – Application to built-up walls.

This is the third TN in our series of four that replace former guidance in TN98.

After a quick recap of TN113 and TN114, we introduced the new guidance, discussing the scope and key takeaways.

Following the presentation, we answered questions about this guidance.

CWCT Webinar 04 - Embodied carbon tool (FaCE), Part 1, January 21 2026

This webinar introduced our recently published embodied carbon calculation tool, FaCE, produced in collaboration with WSP.

After a brief introduction, we had a walkthrough of the tool, showing the various inputs and subsequent results.

We intend to arrange a second webinar to show a more complex example using the tool.  Prior to this, we would really like you download and try using the tool, and then provide your feedback.  This is really important – we are very keen to make this tool as useful as possible, and feedback will help with this process.  Please click here
