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.

These days, more homeowners (and renters) are interested in making green home improvements, and they’re particularly interested in knowing which improvements have a low cost and a high (or fast) payback—i.e., a good Return on Investment, or ROI. A few of the most common suggestions for easy, low-cost projects that reap significant savings (in energy, water, and dollars) are:
- Switch to LED and/or compact fluorescent (CFL) light bulbs. (Note: When buying CFLs, choose low-mercury products. And CFLs cannot be thrown in the trash; because they contain mercury, they must be recycled by a hazardous waste facility. Some stores, such as Home Depot, collect used CFLs.)
- Switch to Energy Star appliances and electronic equipment when it’s time to replace old units.
- Install Energy Star ceiling fans, to reduce or eliminate the need for air conditioning.
- Switch to WaterSense plumbing fixtures (e.g., dual-flush or other high-efficiency toilets, and ultra-low-flow faucets and showerheads).
- Insulate your hot water pipes; and add insulation to your attic (and/or walls and basement).
- Have a home energy audit done to check for air leaks and identify other inefficiencies or areas that need improvement; a home performance contractor should then make the needed improvements. More and more companies are springing up to offer these services. (One of the first companies on the scene was Recurve, formerly called Sustainable Spaces.) You can search here for a contractor near you who has been accredited by the Building Performance Institute.
For other ideas and helpful cost/benefit assessments, check out this new book: Green Sense for the Home: Rating the Real Payoff from 50 Green Home Projects, by Eric Corey Freed and Kevin Daum (Taunton Press, April 2010). Here’s the publisher’s description of the book: “When does a green home project make financial sense? The authors of this book provide the answer to this and other questions relating to the cost (and relative value) of environmentally friendly home improvements. They walk readers through 50 green home projects and break them down according to the positive impact they have on the environment, as well as the impact they may have (both positive and negative) on the reader’s wallet. They evaluate a wide array of projects, including insulating pipes, weatherizing doors and windows, composting and recycling trash, installing a solar hot water heater, installing green countertops, upgrading appliances, building with reclaimed materials, and installing radiant heat.”
Other recent books include Green Home Improvement: 65 Projects That Will Cut Utility Bills, Protect Your Health & Help the Environment by Daniel Chiras, PhD (RS Means) and This Green House: Home Improvements for the Eco-Smart, the Thrifty, and the Do-It-Yourselfer by Joshua Piven (Abrams).
For additional information and tips, these are some online articles and websites with lists of green improvements that are good investments:

The 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.
Platinum 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.

The following websites have some of the most well-presented and up-to-date, free online collections of case studies (or profile articles with in-depth project information) on green homes and green buildings around the country. They feature new construction as well as renovation projects.
These three sources provide case studies and information on residential projects only (primarily single-family homes):
These sites primarily feature commercial and institutional buildings, though they also include some case studies of residential projects:
- High Performance Buildings Database provided by the U.S. Department of Energy and BuildingGreen. The case studies in this database are very comprehensive; they include information on costs, the team process, and lessons learned, as well as details on the projects’ green strategies and materials. Currently, the database contains case studies on more than 275 buildings, including more than 130 LEED certified projects. Note: In order to get full access to the case studies through the BuildingGreen site, you have to be a member/subscriber (which I believe is well worth the price if you’re actively involved or have a strong interest in green building). If you’re not a subscriber, you can get free access to complete versions of a subset of those case studies (112 of the 275) via the Department of Energy’s database (unfortunately, this site hasn’t been updated for a few years, so it doesn’t include the most recent projects that are posted on BuildingGreen). In addition, you can see complete versions of some of the LEED case studies via the U.S. Green Building Council’s site (select “Projects with Case Studies” on the search form), and case studies on the annual award winners of the AIA COTE (American Institute of Architects’ Committee on the Environment) Top Ten Green Projects via the AIA’s website.
I have written many case studies on green building projects over the years. In addition to the two recent Green Building Advisor case studies mentioned above, I’ve prepared in-depth case studies on the David Brower Center, Berkeley; Alder Creek Middle School, Truckee; Colorado Court affordable housing, Santa Monica; the Linden Street Apartments, Somerville, MA, and other projects. Links to some of my published case studies are posted on MLandman.com.
