Newsletter articles - LEED v4 and Concrete Mixes

In May, the committee published two articles in SEAW's Equilibrium:

A study of the carbon impact of Seattle's continuously-approved mix design compared to NRMCA averages.

A primer on some of the alphabet soup of terms used in LEED v4 and other sustainability discussions, particularly related to LCA (that's life cycle analysis).

More tall(er) wood in Vienna

Here's a story on a proposed 276-foot wood building in Vienna. The comment related to fire is interesting given the discussions going on in the US. And another article from Dezeen with more renderings and graphics.

Introduction to LEED v4

Cascadia and LMN are hosting an Introduction to LEED v4 on May 4. From Cascadia:

On October 31st of this year, registration for LEED v2009 will be officially closed, and less than 5 years from that, on June 30th, 2021 -- known as the Sunset of LEED v3 -- no project will be receiving certification under v2009.

LEED v4 represents the future of green building. However, LEED v4 is quite different from the previous version in many ways --  different rating system, redefined prerequisites and credit requirements, a heavier focus on materials, as well as an expansion to cover more building types. All with a greater aspiration to encourage projects to do more good.

Knowing the upcoming change can vastly impact our industry and leave you with questions, Seattle Collaborative is hosting a presentation to introduce the upcoming LEED V4 for you, so reserve your ticket and come learn the vital basics about LEED V4. The presentation is approved for 1 hour of AIA Continuing Education credit and 1 hour of USGBC Continuing Education credit.
