We are working on a Core & Shell project with a developer that we work with frequently. I'm looking for advice on best approaches to achieving the Whole Building Life Cycle Assessment credit- we haven't used TALLY and done this type of analysis before. What are some approaches to achieving this credit that others have found successful? I think our options are 1/ hiring a consultant to do the assessment or 2/ learning Tally or another tool and doing the analysis ourselves. Are there other options? We do have a sustainability / LEED consultant on board.

I won't try to pitch one tool or another, but I should advise you that LEED v4.1 has some important credit changes that make it both easier to apply for the credit and to achieve a larger number of potential points. Fortunately the USGBC is allowing a credit by credit substitution with LEED v4 during the v4.1 beta period. We are holding a webinar to mark the release of our v4.1 LCA guide on the 22nd. The guide is applicable to any LCA tool you may be using to achieve the credit and could be helpful in your decision to perform the analysis internally or not. https://register.gotowebinar.com/register/5659013023847490050

We’ve been using the Athena Impact Estimator tool, but are currently going back and forth with reviewers because LI #100001982 asks for the system boundary to include several categories not actually evaluated by Athena’s A-C Cradle to Grave analysis (B1 Product in Use, B2 Maintenance, B3 Repair, B5 Refurbishment, C3 Waste Processing). Has anyone else encountered this? While the Athena tool is recommended here doesn’t seem to be published guidance on how to supplement the Athena analysis to cover all these bases. From:

For those in the Boston area, have an office in the Boston area, or find themselves (intentionally or otherwise) in Boston on May 31st, I would highly recommend attending the BSA’s upcoming 1-day conference on Embodied Carbon in Buildings. There are many fantastic experts from all over the country that will be speaking (including a number of people in this group), so it should be a great conversation about the topic. There are only 25 spaces left, so if you are thinking about attending, you should register soon before it sells out. https://www.architects.org/programs-and-events/embodied-carbon-buildings Thanks, Andrea Andrea Love AIA, LEED Fellow Principal and Director of Building Science alove@payette.com 617-895-1025 PAYETTE 290 Congress Street, Fifth Floor, Boston, MA 02110 | 617-895-1000 payette.com | Twitter | Instagram | LinkedIn 2019 AIA Architecture Firm Award
