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 (buildings, homes, offices, and stores) to my online listing of LEED Platinum Certified Building Projects Worldwide, which I had last updated a year ago. The listing is organized by country and—within the U.S.—by state. Some of the listed projects are linked to online case studies. The listing includes projects of all types, from every LEED rating system: New Construction (and Major Renovations), Existing Buildings/Operations & Maintenance, Neighborhood Developments, Commercial Interiors, Core & Shell, Homes, Schools, 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; a year ago only 16 countries had LEED Platinum rated projects. The nine countries that gained their first LEED Platinum projects over the past year are: France, Hong Kong, Italy, Japan, Mexico, the Netherlands, Switzerland, Taiwan, and Turkey. The other countries with LEED Platinum projects are: Australia, Brazil, Canada, China, Finland, Germany, Great Britain, India, Saudi Arabia, South Korea, Spain, Sri Lanka, Sweden, Thailand, the United Arab Emirates, and of course the United States. 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. A year ago, Alabama and West Virginia did not yet have any LEED Platinum projects, but now they do.

In terms of the absolute number of LEED Platinum certified projects in each state, here are the top 5 states with the greatest number of LEED Platinum projects (at last count):

• California (164 projects)
• Oregon (64)
• New York (61)
• Texas (51)
• Massachusetts (40)

So California has more than 2.5 times more Platinum projects than any other state—but that’s not too surprising since it’s the most populous state in the country.  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 when you add in the 50 states, here are the Top 5 with the greatest number of LEED Platinum projects per capita:

1. Washington, D.C.
2. Oregon
3. Montana
4. Vermont
5. New Mexico

The range of Platinum project types is very broad. In addition to high-profile projects (such as the iconic TransAmerica Pyramid in San Francisco, which got the Platinum rating for its upgrades under the LEED for Existing Buildings: Operations & Maintenance rating system) and a number of high-end offices, retail spaces, and luxury residences, LEED Platinum projects also include several public buildings and many modest homes and affordable housing developments. For example, there are dozens of Habitat for Humanity-built LEED Platinum homes around the country, and more than 75 affordable Platinum homes built in New Orleans alone through various initiatives, including Make It Right.

* 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: the Tyson Living Learning Center in Eureka, Missouri; the Omega Center for Sustainable Living in Rhinebeck, New York (which also got a LEED Platinum certification); and the Eco-Sense home in Victoria, British Columbia. The latest project to achieve this certification (along with a LEED Platinum certification) is the Hawaii Preparatory Academy Energy Lab in Kamuela, Hawaii.

Most conventional paints and coatings contain and emit Volatile Organic Compounds (VOCs). Some types of VOCs contribute to smog, and many VOCs are emitted or “offgassed” indoors and contribute to indoor air pollution. VOCs can cause respiratory problems and some are known carcinogens.

I have written a 4-page overview of VOCs and other toxicity issues related to paints and other types of coatings. For the free download, just click on this link:

How to Select Less-Toxic, Low-VOC Paints, Primers, Stains, and Coatings [PDF]

Fortunately, almost every major paint manufacturer (and retailer) now has a low-VOC or zero-VOC product line. Most of these products are also low-odor, as some VOCs are responsible for to that noxious “new paint smell.”

I maintain an online product listing of Low-VOC and Zero-VOC Wall Paints, which I recently updated. The listing includes natural paints (e.g., plant- or mineral-based), as well as more conventional synthetic (e.g., latex/acrylic) paints.

A few paint manufacturers, such as AFM Safecoat and YOLO Colorhouse formulate their entire line of paints and primers to be low- or zero-VOC and low-toxic. While most low-VOC paints are interior paints, some brands (including those two) also offer low-VOC exterior paints.

My listing indicates which paint lines have been Green Seal certified or SCS Indoor Advantage Gold certified. GreenGuard also certifies paints; it has a basic Indoor Air Quality Certified program, as well as a more stringent Children and Schools Certified program. All of these certification programs are primarily focused on testing products’ VOC emissions.

Unfortunately, synthetic paints often contain other toxic compounds, beyond VOCs, such as phthalates (which are endocrine-disrupting chemicals), propylene glycol and glycol ethers (PGEs), certain heavy metals, and toxic biocides or fungicides. (Green Seal’s certification standard prohibits the use of some of those compounds.) See this Pharos article for additional information on paint toxicity.

The sustainability of one’s home depends as much (if not more) on its location as on how the house is built. If you’re looking to buy land or to buy (or rent) a house, consider sustainability criteria when comparing the locations of different properties.

The following are some of the key “location efficiency” issues to consider. (Some of them only apply to buying land that you plan to build on.) Try to choose a spot that meets at least some of these criteria:

Seek a property that…

• …is located close to your (and your family’s) jobs and schools; close to shops, parks, civic buildings, and other services and amenities your family regularly uses; and close to public transit stops—ideally within walking distance (i.e., less than 1/4 mile, or 1/2-mile max.). Living in close proximity to such things will save you gas, money, and driving time; reduce your stress level and your odds of getting in a car accident; and also reduce traffic and air pollution!
• ...has been built on before. It’s best to choose a property that has an existing house or other structures that can be renovated and reused. (If a structure is unsafe or beyond repair and must be demolished, have it deconstructed carefully so that you can recycle, reuse, donate, or sell its salvageable materials; and then rebuild on its original foundation or footprint.)
• …is an infill site (i.e., surrounded by other developed parcels) that is already (or can easily be) hooked up to existing infrastructure for roads, water, wastewater, and utility lines (to reduce the costs, resource waste, and sprawl associated with extending or building new infrastructure)—unless you’re planning to live entirely off-grid (with on-site power, water, and wastewater treatment). If you are planning to live off-grid, be sure that the property has a good source of clean water on site, as well as adequate solar access and/or wind or biomass resources for generating your own electricity.

And avoid buying or building on a property that…

• …is within a floodplain zone; on a known earthquake fault; or on coastal land that’s susceptible to erosion or located in a tsunami zone;
• …is a Greenfield site (i.e., land that has never been developed / cleared / built on before);
• …contains sensitive habitat, endangered species, wetlands, or prime agricultural land (unless you preserve the key areas for continued agricultural use or conservation, whichever is applicable); or
• …consists of steep slopes (often defined as slopes with a grade of 15% or more), which would need to be substantially graded to enable development of the site. The grading and development of steep slopes can cause soil erosion and increased stormwater runoff, which in turn can cause water pollution, flooding, and potentially mudslides.

Living in an environmentally sensible and sustainable location has numerous benefits. You can reap significant financial savings (e.g., by reducing the amount of driving you have to do; or by avoiding or minimizing the need to build new infrastructure or to do extensive site grading). Location efficiency can also yield broad, collective benefits for society and our shared environment, such as:

• reducing sprawl-related automobile dependence, traffic, and air pollution;
• protecting public health, environmental health, and the climate;
• conserving natural resources, habitat, and open space; and
• contributing to the creation of livable, walkable, healthy, and vibrant neighborhoods that enhance your community’s quality of life and local economic opportunities.

One of the best ways to learn about green homes is to explore examples of real-world projects—by touring green homes or reading about them online. Completed projects can give you ideas for your own home. And we all benefit from hearing about not only the most successful aspects of model projects, but also about the lessons learned the hard way by homeowners or builders who have already “blazed the trail.”

The following websites feature free collections of case studies (or profile articles with in-depth information) on green homes around the country. Some of these sites showcase home renovations and remodels, as well as new homes.

• GreenBuildingAdvisor.com’s Green Homes case studies include technical data on energy use/savings, cross-section drawings for builders and designers, multiple photographs of each home’s features, and in-depth project descriptions. You can search for specific case studies by region, and there are categories for Remodels and Near-Zero-Energy Homes. Among the case studies are two that I wrote: one about a green addition and renovation in Pacifica, CA, and another about a beautiful solar home on the Oregon coast.

• Natural Home magazine’s articles on green home projects

• LEED for Homes certified project profiles, new homes only (U.S. Green Building Council)

• Passive Houses (Passive House Institute)

• GreenPoint Rated remodel case studies (Build It Green, California)

• REGREEN remodeling projects and case studies (American Society of Interior Designers / USGBC)

• High Performance Buildings Database case studies (U.S. Department of Energy / BuildingGreen): Go to “Search Options,” then select “Building Type,” and choose “Single-Family Residential,” or search by location. Most of the case studies in this database are on commercial and institutional buildings.

• Mother Earth News: Green Homes section, which regularly includes articles that profile green home projects

In addition to the LEED for Homes, Passive House, and GreenPoint Rated certifications that are mentioned above, homes can also be certified under the rigorous Living Building Challenge program. The first home to achieve the Living Building Challenge certification is the Eco-Sense home in Victoria, British Columbia. The International Living Building Institute has posted this comprehensive case study on the Eco-Sense home.

Please click here to see our more recent update and analysis of LEED Platinum projects (from January 2012). (Note: That post has more current data, so it supercedes the following, older post.)

Platinum is the highest rating in the LEED green building rating system; it’s one level higher than Gold. Building projects that have attained this rigorous level of certification are among the greenest in the world.

I recently added the latest set of Platinum-rated projects (buildings, homes, offices, and stores) to my listing of LEED Platinum Certified Building Projects Worldwide. This unique listing is organized by country and—within the U.S.—by state. Some of the listed projects are linked to online case studies. The listing includes projects of all types, from every LEED rating system: New Construction (and Major Renovations), Existing Buildings/Operations & Maintenance, Commercial Interiors, Core & Shell, Homes, Schools, and Retail. It is primarily compiled from the data provided in the USGBC/GBCI’s directory of LEED certified projects and the USGBC’s most recently posted list of LEED for Homes certified residences.

There are now hundreds of LEED Platinum certified projects. As of my latest review of the data (at the very beginning of 2011), it appears that projects in 47 of the 50 U.S. states (all states except Alabama, North Dakota, and West Virginia) have achieved the LEED Platinum rating to date, along with projects in Washington DC and Puerto Rico.

California has more than 130 LEED Platinum certified projects (at last count), which is more than twice as many as there are in any other state, and it’s also more than twice as many as California had only a year ago.  In terms of the absolute number of LEED Platinum certified projects in each state, California is followed by Oregon (with almost 60 projects), and then Texas, New York, and Massachusetts (each of which has between 30-40 projects). If you take state populations into account, Oregon clearly has the lead (for the greatest number of LEED Platinum certified projects per capita).

Worldwide, Platinum rated projects now exist in 16 countries. Outside of the U.S., there are projects in Australia, Brazil, Canada, China, Finland, Germany, Great Britain, India, Saudi Arabia, South Korea, Spain, Sri Lanka, Sweden, Thailand, and the United Arab Emirates. Among these, India has the most, with 20 projects so far.

The range of Platinum project types is very broad. In addition to high-profile projects (such as the California Academy of Sciences in San Francisco, and the William J. Clinton Presidential Center in Little Rock) and a number of high-end offices and luxury residences, LEED Platinum projects also include several public buildings (such as San Jose City Hall) and a surprising number of affordable housing projects. The following are just a few examples of the many affordable housing projects that have achieved the LEED Platinum rating: 51 single-family, detached homes built by Habitat for Humanity in St. Louis, MO; the General Colin L. Powell Apartments in the South Bronx, NY; Wisdom Way Solar Village homes in Greenfield, MA; Autumn Terrace mixed-use housing development in San Marcos, CA; Vista Dunes in La Quinta, CA; and a variety of affordable homes in New Orleans, Louisiana.

Note: 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, three projects have achieved the Living Building Challenge certification: the Tyson Living Learning Center in Eureka, Missouri; the Omega Center for Sustainable Living in Rhinebeck, New York (which also got a LEED Platinum certification); and the Eco-Sense home in Victoria, British Columbia.

Outdoor education is an important branch of environmental education. The concept of “nature-deficit disorder” is described in the bestselling book Last Child in the Woods.

It’s especially important for urban youth, who may never have spent any time outside of their neighborhoods or cities, to be given opportunities to explore and learn in nature/wilderness settings. At-risk youth can benefit greatly from outdoor learning experiences provided by wilderness programs such as Outward Bound, as well as farm-based programs like those offered by the Center for Land-Based Learning.
