The answer is 190 kg CO2e/m2 (with a lot of caveats to go alongside).
Why is counting the upfront carbon performance level1 for CAT B office fit-out important?
Through an optimistic lens, the shell and core plus CAT A of a building last 60 and 20 years respectively, with multiple CAT B fit-outs every 5 to 10 years. Over 20 years, the carbon impact of CAT B fit-outs can equal that of the initial construction. This cumulative CAT B carbon cost is why our research is so important.
Peers in the fit-out industry can use this cross-sector research as a starting point. Stakeholders will be able to benchmark their own limits, set upfront carbon limits, and encourage transparent industry discussions about the research that is still needed.
Day to day everyone can play a part by:
1. Setting accountability
2. Establishing baselines and limits
3. Engaging with stakeholders
4. Share and collaborating
The cross-sector research findings have been submitted to the UK NZC Buildings Standard to help inform their setting of upfront carbon limits for the office sector going forward. To find out more download your copy: https://shorturl.at/GaEu2
