OH MAN THIS IS INCREDIBLE

it's a good question. according to their calcs, the CLT requires more wood for the same floor area of panels. it's about 55% more embodied carbon for the CLT v. DLT. it's also heavier so there are also slight knock on effects for column sizing and foundations.
you generally wan't the least amount of fiber, and the least amount of table time.
that being said on projecte i've worked on - DLT has been slightly less than CLT for estimates
assuming 6 units per floor (3 per stair core) - you're looking at a 10% reduction in embodied CO2 per unit.
alas, US single stair regs don't allow 8 story PABs...
Was this a straight material swap or did they redo the structural calculations?
I was hoping they wouldn't confound C in cellulose with C as an offset.
