FUTURE FOCUSED
FUTURE FOCUSED
Whilst arguments against net-zero whole life carbon tend towards a fear of the unknown , we can still think about the future . There is no one-size fits all solution . What may work on one project may not be the same elsewhere . It is important to get buy-in from everyone on the team that you are seeking to achieve a low-carbon structure , and taking advantage of periods of value engineering is really important . Traditionally an area where sustainable measures are dropped , this is now key to helping to reduce the embodied carbon load .
Typically , at Thornton Tomasetti we can achieve a 10-20 % reduction of embodied carbon below project baseline . However , in more aggressive projects we have managed to achieve a 40 % reduction . We have been collecting the embodied carbon data for all of our structural projects over the last eight years . As a result , we know that , for most building types , we must focus on slabs as the biggest contributor to embodied carbon . We also know that green rating systems have a low impact on reducing the
