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:

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.

While the majority of businesses still have a long way to go to be environmentally sustainable, it’s clear that interest in greening the business world is on the rise. One of the many signs of this is the growing number of Sustainable MBA programs cropping up around the country (e.g., the Presidio Graduate School’s MBA in Sustainable Management, Dominican University’s Green MBA, and at least 20 others). Another indicator is the gradual greening of massive companies like Walmart, which recently developed a Sustainability Index to assess the sustainability of its supplier companies. We’re also seeing the emergence of “green” banks, such as New Resource Bank. And some cities and counties have established Green Business certification programs for local businesses.
Given the significant environmental, social, economic, and health impacts (as well as the political influence) that many companies have, it’s critically important that we support and create businesses that implement responsible and sustainable policies and practices—businesses that reflect our values and whose practices and products aren’t compromising the length or quality our lives.
Among U.S. companies, a few that have shown early and exceptional leadership in sustainability are: Patagonia (the recreation/outdoors outfitter), Interface (the commercial carpet company), Seventh Generation (household products), and Straus Family Creamery (organic dairy).
Two of the many recent books on green business are:
And a seminal book on green business is:
These are some of the major online hubs for news and information on green business:
Also, author and consultant Andrew Winston has a good green business blog.
And last but not least, the following are some of the most prominent groups and networks that help companies improve their corporate social responsibility (CSR) efforts and their environmental performance:
