The chaotic and frustrating process of searching for transparency documents is getting a total overhaul with a better search and pre-verification by GBCI.

by Paula Melton

If you’ve attempted the Building Product Disclosure and Optimization (BPDO) credits under LEED v4 or 4.1, you probably have war stories about finding, verifying, and documenting those credits—and then potentially having your environmental product declarations (EPDs) or Health Product Declarations (HPDs) rejected because of something you missed in the fine print.

All that frustration is about to go away. Meet the Better Materials initiative from the U.S. Green Building Council (USGBC) and Green Business Certification Inc. (GBCI).

Arc, the performance-measurement tool from USGBC’s for-profit arm, is now available to anyone with access to a web browser.

Have you ever wondered how your building measures up against the highest-performing buildings on the planet? With the Arc online software tool, you can now find out—for free.

Lots of credits are more achievable under v4.1, but should we celebrate? What about the environmental impact?

by Nadav Malin

After we announced the v4.1 “Should I Upgrade?” content on LEEDuser (scroll down for an example here), we got challenged by Nick Semon of Re:Vision Architecture in Philadelphia:

After ten years online, LEEDuser has become an institution. And there’s a good reason we’re still here: you.

The Vision

LEEDuser grew out of a very simple inspiration: LEED shouldn’t be so hard!

In 2008, LEED was rapidly gaining traction in the marketplace, but most people felt they needed have to hire a dedicated LEED consultant for every project, jacking up the cost significantly.

Computational design scripting for integrated performance analysis

by Elliot Glassman and Joshua Radoff

The building sector is the largest contributor to greenhouse gas emissions, and heating, cooling, and lighting are all major sources of these emissions. The solution? Good passive design can minimize the need for these end uses even while providing enhanced thermal comfort.

These updates are the best thing to happen to LEED in a very long time.

by Joshua Radoff

It’s been a while since a LEED update generated much excitement. Not like the heady days of 2009 when v3 was released, and project teams were lining up to get things registered because of the market power LEED was commanding.

Leveraging computational design scripting for daylight and views

by Elliot Glassman and Joshua Radoff

There is a mountain of research to support the positive impacts of good daylighting, but there is less guidance on how to do it well.

Version 4.1 for BD+C and ID+C, coming out in December, is about creating “stepping stones,” not about changing the fundamentals.

by Paula Melton

I sat down with Melissa Baker of the U.S. Green Building Council (USGBC) at Greenbuild to talk about LEED v4.1 for Building Design and Construction (BD+C) and Interior Design and Construction (ID+C). Baker is senior vice president for technical core. Here’s what I found out.

First, the timeline: USGBC will release a draft of the rating system in December. You’ll have a month to peruse that while they build up the registration and submittal infrastructure. The beta will start in January 2019.

A case study of Legrand’s triangulation between LEED, Better Buildings Challenge, and GHG emission reduction efforts

I count myself among a subset of sustainability professionals who work in the context of both building performance and enterprise-level strategy and planning.

Buildings need renewables—but we need to look beyond the site.

by Joshua Radoff

No man is an island, and neither is a building.

LEED should reward urban projects for vegetation and green infrastructure, but it seems to have lost sight of this goal.

by Joshua Radoff

When LEED v4 BD+C was released, there were a handful of improvements that I was really excited about: the new interior lighting credit, better daylight metrics, transit points based on number of trips, and envelope and mo

Lots of credits are out, Interiors are in, and we’re seeing our first direct measurements of carbon in LEED.

by Paula Melton

The U.S. Green Building Council (USGBC) has released a first draft of LEED v4.1 for Building Operations and Maintenance (LEED O+M). If approved by the members, this new set of rating systems will represent a radical shift in how LEED measures the performance of existing buildings.

LEED v4.1, a new iteration of the green building rating system will be piloted in 2018 with the goal of smoothing over rough spots

The latest version of LEED, LEED v4, became mandatory a little over a year ago. That was just after the U.S. Green Building Council’s 2016 Greenbuild conference. This year at Greenbuild, USGBC announced that it is fast-tracking development of a new iteration, LEED v4.1.

If LEED does not incorporate deep CO2 reductions as a requirement, it will fail its most important test of leadership

by Greg Kats

Over the last 20 years LEED has become the dominant U.S. green building design standard and is the most widely accepted and influential green building standard globally. This is an extraordinary achievement and has made for healthier, more productive and greener homes, workplaces, schools, hospitals and public spaces for tens of millions of families, students and workers.

If a new California law is successfully implemented, thanks in part to LEED's influence it will have a meaningful impact on carbon emissions from the supply chain.

by Nadav Malin

I first got interested in California’s Assembly Bill 262—signed into law by Governor Brown this week—because it appeared to be thrusting Environmental Product Declarations (EPDs) into the mainstream construction industry spotlight. Until this bill, EPDs had been an arcane tool of interest primarily to sustainability professionals.
