Is anyone out there actually seeing LCA’s show closer to a 50/50 split on embodied vs operational on high performance buildings that move towards electrification, renewable energy, and clean grids?
Because this seems to be the messaging Architecture 2030… :
or CLF’s graphic showing embodied being the heavy dominator, like this:
I post this because due to some amazing LCA and research work by @lkaufman and me (#humblebrag) - we have not seen high performance building profiles shift the total ghg emissions towards embodied.
We still very much see an operational dominating emissions profile on a number of low EUI buildings, EVEN ones that lean towards electrification, on-site renewable energy, and have future grid cleaning scenarios. Even with a concrete/steel structure, our last LCA was showing an 80/20 split towards operational on a grid that is cleaning now and supposed to be zero-carbon by 2050.
What is everyone else seeing?
