residential green building

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):

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.

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.

  • 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.

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.

If you’re thinking about doing a major renovation of your home or building a new home, I hope you’ll avail yourself of the growing number of resources on how to design and build houses that consume very little energy and that produce at least as much energy as they consume (i.e., net-zero-energy homes).

One of the most recent books on this topic is: Energy Free Homes for a Small Planet: A comprehensive guide to the design, construction, and economics of net-zero energy homes, by Ann V. Edminster (Green Building Press, December 2009). The publisher says: “Energy Free is designed to equip building professionals and homeowners alike with a toolkit for creating homes that use no more energy than they produce—this means homes that are free from the vagaries of energy-price fluctuations and that help to free society of the high political and environmental costs of fossil fuels. The author includes…step-by-step guidance on how to make decisions that will yield an energy-free residential project, whether a single-family home or multifamily building, new or existing, in an urban or a rural setting.” For more info about the book, click here.

One approach to designing and renovating homes so that they use very little energy is the Passive House approach, espoused by the Passive House Institute. The Passive House (or Passiv Haus) standard was originally developed in Germany. Passive houses are designed to reduce energy consumption by 80-90% compared to conventional houses. The first new home being built as a Passive House in California is a project of the Community Land Trust Association of West Marin (CLAM). The home, known as the Blue2 House, is an affordable second unit behind another home in Point Reyes Station; the main house was also renovated using some Passive House techniques.  CLAM is chronicling the home’s construction process and progress on a blog.

Other resources worth checking out include: GreenBuildingAdvisor.com, which has published several case studies of net-zero and near-net-zero energy homes; the Home of the Future program from the Sacramento Municipal Utility District (SMUD); the Department of Energy’s Building America program; and Affordable Comfort Inc.’s Thousand Home Challenge and Deep Energy Reductions programs.

I’d like to let everyone know about these important new books, which were written by a few of my esteemed colleagues. Please click on the links below for more information about each tome:

Thriving Beyond Sustainability: Pathways to a Resilient Society, by Andres Edwards (New Society Publishers) — This book will be available in May (2010), but it can be pre-ordered now. Here’s an excerpt from the publisher’s description of the book: “Thriving Beyond Sustainability draws a collective map of individuals, organizations, and communities from around the world that are committed to building an alternative future—one that strives to restore ecological health; reinvent outmoded institutions; and rejuvenate our environmental, social, and economic systems. The projects and initiatives profiled are meeting the challenges of the day with optimism, hope, and results, leading the way in relocalization, green commerce, ecological design, environmental conservation, and social transformation.” Click here to read reviews of the book, the book’s Foreword (by Bill McKibben), Table of Contents, or an annotated bibliography.

Fundamentals of Integrated Design for Sustainable Building, by Marian Keeler and Bill Burke (John Wiley & Sons, 2009)— This book serves as an in-depth textbook for design students and a comprehensive reference for practitioners. It presents the history, issues, principles, technologies, process, and practice of sustainable building design, as well as case studies of model projects. In addition, it promotes active learning by providing design problems, research exercises, study questions, and discussion topics.

The good folks at BuildingGreen recently announced their eighth annual Top Ten Green Products. Of the ten they selected, three of my favorites are: Baltix office furniture; Mobile solar power generators; and Pentadyne flywheel energy storage for uninterrupted power supply systems (the flywheel essentially uses magnets and physics, as an alternative to using batteries).

GreenDollarSignThe following are key online resources for information on federal, state, and local environmental tax credits, rebates, and other financial incentives. Most of the incentives that are available are for installing energy-efficient equipment or renewable energy (e.g., solar) technologies.

FEDERAL

These are good directories of federal income tax credits, grants, other incentives for energy-efficient products—for consumers, as well as businesses, builders, and manufacturers:

Click here for a clear summary of the main tax credits currently available: essentially 30% of various energy-efficiency improvements (up to $1,500) and 30% of the cost of solar energy installations. For info on federal grants (to organizations and agencies), go to Grants.gov.

STATE AND LOCAL

Check out the Database of State Incentives for Renewables and Efficiency for a compendium of options, organized by state. Also check with your municipality (city and county governments) and local utility companies. Many offer their own green rebates and incentives. And this is a great summary of energy-efficiency grants and funds provided to state and local agencies by the 2009 economic stimulus/recovery bill (ARRA).

CALIFORNIA

For those of you who are in California, there are numerous entities offering green rebates and other incentives. Take a look at these resources:

If you know of other useful directories or resources related to green financial incentives, or if you have made use of energy tax credits or other green incentives, please share your experiences or suggestions by leaving a comment below.

NEW (added 1/19/10): Also check out the directory of energy rebates and tax credits at EnergySavvy.com. Enter your zip code and the site will give you a list of applicable state, local, and federal incentives.

I recently added the latest set of Platinum rated projects to my listing of LEED Platinum certified building projects worldwide. The listing is organized by countries and states, and some of the projects are linked to in-depth case studies. As of this month (October 2009), I know of LEED Platinum certified projects in 44 U.S. states plus Puerto Rico, as well as projects in 9 other countries: Australia, Brazil, Canada, Germany, India, Saudi Arabia, South Korea, Sri Lanka, and the United Arab Emirates. There are all types of Platinum projects: commercial, residential, institutional…new construction as well as renovation.

LEED_platinumPlatinum is the highest rating in the LEED green building rating systems. Building projects that have attained this rigorous level of certification are among the greenest in the world.

I update the listing every month or two. If you know of a project that has officially achieved LEED Platinum certification but is not yet included in the listing, please let me know.
