Unveiling of LEED v4
SET TO DRIVE TRANSFORMATION IN BUILT ENVIRONMENT/
WHEN THE U.S. Green Building Council (USGBC) created the LEED
green building program in 2000, no one could have known that this idea
would turn into a global movement with more than 1.5 million square
feet certifying to LEED every day. Today, LEED has grown to more than
184,000 LEED credentialed professionals and over 51,000 projects participating in LEED, making up 9.7 billion square feet of construction space.
The hallmark of LEED and its ability to affect market transformation is its continuous improvement cycle. Fueled by input from the green
building community, USGBC and hundreds of volunteers have worked
to evolve LEED as our understanding of building science, the emergence
of new technologies, the needs of the marketplace, and the deepening of
our environmental priorities change.
The result, LEED v4, is a technical update to the rating systems
that offers a new global perspective, an improved user experience and
a better focus on building performance. This past November, USGBC
launched LEED v4 at the Greenbuild International Conference and Expo
With a focus on performance outcomes, LEED v4 is structured to help
LEED users have a better understanding of how to manage their buildings'
performance to ensure they are reaching their full performance potential.
Performance is addressed in technical changes within each credit category:
Location and Transportation. For the ﬁrst time in the building and
construction rating systems, Location and Transportation is called out as
a separate category. The purpose is to reward projects within relatively
dense areas, accessible to a variety of transportation options and on sites
with development constraints.
Sustainable Sites. Sustainable Sites emphasizes the vital relationships among projects, ecosystems and ecosystem services. This category
drives site performance by encouraging restorative environmental solutions (on- and off-site) that take advantage of ecosystem services and
preserving habitat and biodiversity.
LEED IN THE WORLD
PAINTING THE PICTURE OF LEED V4
What does LEED v4 look like? With LEED 2009, the primary changes
were foundational, such as rating system alignment, the development of
LEED Online v3 and updates to the professional credentials and certiﬁcation process. LEED v4 builds on these changes to improve the clarity,
functionality and interconnectivity of the LEED program while focusing
on additional improvements described below.
NEW MARKET SECTORS
The building industry now uses LEED on a wider variety of project
types than ever before. From stadiums to convention centers, commercial offices to hospitals, each space type has unique needs and challenges
when using LEED. LEED v4 addresses 21 different market sector adaptations - each reviewed by market leaders either owning, designing or
operating those space types - to identify the unique needs of that market and appropriately address those needs within revisions to LEED
v4. LEED v4 provides new solutions for the following sectors:
NUMBER OF LEED PROJECTS REGISTERED &
CERTIFIED IN TOP REGIONS BY GSM
and North Africa
* Existing schools
* Existing retail
* Data centers (new and existing)
* Warehouses and distribution centers (new and existing)
* Midrise residential
IMPROVED ENVIRONMENTAL OUTCOMES
LEED v4 emphasizes the potential for projects to contribute positively to
their communities and to the planet. USGBC developed new impact categories that serve as the driver for determining the technical requirements
of the rating system and reposition the LEED development trajectory
from encouraging buildings to "do less bad" and instead "do more good."
* Gross square meters (GSM) are reported in millions.
* Includes projects registered through the USGBC, GBCI, Canada GBC, and Indian GBC (partial data).
