Platinum
is the highest rating in the LEED (Leadership
in Energy and Environmental Design) green building certification program.
Building projects that have attained this rating are among the greenest in the
world.*

I
recently added newly certified Platinum-rated projects to my online listing  of  LEED Platinum Certified Building Projects Worldwide. The listing includes
projects of all types, from every LEED rating system: Homes, Schools, New
Construction (and Major Renovations), Existing Buildings/Operations &
Maintenance, Neighborhood Developments, Commercial Interiors, Core & Shell,
and Retail.

As
of my latest review of the data (at the beginning of January 2012), it appears that there are now more than 1,045 LEED Platinum rated projects worldwide. While the
vast majority of LEED projects (almost 950 of them) are located in the United
States (where LEED was created), Platinum rated projects now exist in 25  countries.
After the U.S., India is the country
with the most Platinum projects, with about 35 projects so far (up from 20 a
year ago). Canada  and China also have many Platinum
projects.

Within
the United States, 49 of the 50 U.S.
states (all states except North Dakota)—plus Washington D.C. and Puerto
Rico—now have building projects that have achieved the LEED Platinum rating. In
terms of the absolute number of LEED Platinum certified projects in each state,
California
has the most (with at least 164 projects, at last count), followed by Oregon
(with 64 projects), and then New York
(61), Texas
(51) and Massachusetts
(40). However, on a per capita basis
(i.e., as a percentage of population size), Washington D.C. has more LEED
Platinum rated projects than any of the states. And among the 50 states, Oregon has the greatest number of LEED
Platinum projects per capita, followed
by Montana, Hawaii, Vermont, and New Mexico

Homes
that have achieved the LEED Platinum rating range from luxury residences to
modest houses to rental apartments in multi-family affordable housing
developments, and everything in between. They also span a broad range of design
styles, from traditional to modern.

Here
are case studies of a small but diverse sample of LEED Platinum-rated
residences:

Another green building certification, which is widely considered to be an even
higher bar to reach than LEED Platinum, is the Living Building Challenge.
To date, four projects have achieved the Living Building Challenge
certification, including one home: the Eco-Sense home  in
Victoria, British Columbia.
