Low-Cost, High-Payoff Green Home Improvements and Retrofits

Homeowners (and renters) are increasingly interested in making green home improvements, and they’re particularly interested in knowing which improvements have a low cost and a clear payback—i.e., a decent Return on Investment, or ROI. Here are some commonly agreed upon suggestions for relatively easy and economical projects that reap surefire savings (in energy, water, and dollars):

  1. Switch to LED and/or compact fluorescent (CFL) light bulbs. (Note: When buying CFLs, look for low-mercury products. Also, because CFLs contain mercury, they cannot be thrown in the trash; they must be recycled by a hazardous waste facility. Some stores, such as Home Depot, collect used CFLs. You can find other places near you that take used CFLs on Earth911.com.)
  2. Switch to WaterSense plumbing fixtures (e.g., dual-flush or other high-efficiency toilets, and ultra-low-flow faucets and showerheads). [MORE INFO here.]
  3. Switch to Energy Star appliances and electronic equipment when it’s time to replace old units. Install an Energy Star ceiling fan(s), to reduce or eliminate your use of air conditioning.
  4. Insulate your hot water pipes and water heater; and add insulation to your attic (and/or walls and basement).
  5. Have a home energy audit done to check for air leaks and identify other inefficiencies; a home performance contractor should then make the needed improvements. More and more companies are springing up to offer these services. (One very experienced company in California is Advanced Home Energy, formerly called Recurve.) You can search here for a contractor near you who has been accredited by the Building Performance Institute. If you live in California, check out the information provided by Energy Upgrade California.

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 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).

A number of federal, state, and local tax credits, rebates, and other financial incentives are available for installing energy-efficient equipment or renewable energy (e.g., solar) technologies at your residence.

The BP Oil Disaster in the Gulf of Mexico: How to Help

Just a quick post to provide links to information on the BP oil drilling disaster in the Gulf of Mexico, and some of the key organizations and agencies that are working to minimize the impacts of it and provide emergency rescue and recovery assistance. The oil slick is shaping up to be far worse than BP originally said it could be, and probably even worse than the Exxon Valdez spill. It’s going to be devastating for the ecosystems and animals, as well as fishermen and other people who live in the region. These are a few groups you might want to support, as well as articles linking to other efforts:

Gulf Restoration Network (Donate. Volunteer. )

Institute for Marine Mammal Studies in Gulfport, MS

If you’re on the Gulf Coast, and you see marine mammals (e.g., dolphins, manatees) or sea turtles that have been affected by the spill, please call this hotline: 1-888-767-3657.

To report oiled birds or other wildlife, call this hotline: 1-866-557-1401.

Coalition to Restore Coastal Louisiana: Volunteer registration

“Deepwater Horizon Oil Spill Impact: Get Involved“ article (w/ more links) from Huffington Post, posted on GlobalGreen.org

“Gulf of Mexico Oil Spill: The What, When and Where…and How You Can Help” article (w/ more links) on Planet Green (Discovery)

For additional info on the spill, see these sites:

    And for an overview of BP’s previous accidents and the company’s controversial environmental record, take a look at this Wikipedia page.

    As for longer-term solutions to prevent this type of disaster from recurring, the best things that each of us can do are: 1) to demand that all of our governmental representatives support energy conservation and clean/renewable energy legislation, and 2) to decrease our own consumption of oil, gasoline, fossil-fuel-generated electricity, and petroleum-based products, including plastic. (Reducing our demand for oil will help to reduce the need for drilling and exploration to boost the oil supply.) Look for more details on these topics in later posts.

    Flea and Tick Treatments That Won’t Poison Your Pet

    Fleas and ticks (and mosquitos) can bring severe itching, allergic reactions, discomfort, and even serious diseases (such as lyme disease) to your pets, so it’s important to protect your pets from them. However, studies have found that some common flea and tick control treatments—products that are readily available at stores and have been recommended by many vets—aren’t just harmful to fleas and ticks; they can actually poison pets, and some are also dangerous to humans and other animals.

    Some conventional flea and tick treatments (including many of the topical, spot-on treatments that are applied directly onto pets’ skin, as well as flea collars, powders, and sprays, and even some ingestible products) contain highly toxic pesticides, some of which have been shown to cause a range of serious reactions in pets, from skin problems, vomiting, and excessive drooling to neurological problems (e.g., seizures or uncontrollable shaking), heart attacks, and death. So, tragically, some pesticides end up serving as pet-icides…

    The Center for Public Integrity did a study in 2008, and found that at least 1,600 pet deaths related to spot-on treatments were reported to the EPA over the previous five years. According to the NRDC, cats may be more susceptible to adverse reactions than dogs, since they are more likely to lick the treatments off of their fur and they often lack enzymes for metabolizing or detoxifying the pesticides. Many of these pesticides are toxic to humans, as well, and children are especially vulnerable to exposure.

    Avoid products that contain pyrethroid, pyrethrin, or permethrin pesticides, organophosphate insecticides (such as tetrachlorvinphos/TCVP; chlorpyrifos, dichlorvos, phosmet, naled, diazinon, and malathion), carbamates (e.g., propoxur, fenoxycarb, and carbaryl), or Amitraz. [This list was updated on May 26, 2010.] Many common flea/tick control products contain at least one of these ingredients. (Towards the end of this post, you will find a link to a listing of some specific products to avoid.) Please note: Never use products on cats that are meant for use on dogs (and vice versa), and never give your pet more than the recommended dose.

    It’s disturbing that so many of us might have been unwittingly sickening our animals (and possibly shortening their lives) by using these products, often at the recommendation of our veterinarians, who trusted the manufacturers’ assurances of the products’ safety. It’s yet another example of how you can’t trust that a product is safe just because it’s been allowed into the marketplace. According to the Humane Society, the EPA did not start reviewing pet products for safety until 1996, and there is still a backlog of products that need to be tested. However, the overarching problem is that some ingredients that the EPA had deemed “safe” clearly were not. In 2009, the EPA announced that it would be developing stricter testing and evaluation requirements and could place new restrictions on flea and tick products.

    Fortunately, there’s no need to wait for those changes to take effect. Safe and natural alternative products and methods for controlling fleas and ticks already exist. Here is some guidance from the NRDC on ways to prevent flea problems. And when treatments are necessary, some pet supply stores and many online sites (see links below) now carry flea and tick products that are made up of plant-based ingredients, such as peppermint oil, citrus oil, clove oil, or Neem, which is a natural insecticide that comes from a tree. See the NRDC’s Flea and Tick Product Directory to look up the ingredients and risks of specific products. Some flea and tick solutions can even be made at home. Fleas and ticks are repelled by rosemary, thyme, eucalyptus, and lavender. So to ward off the bugs, you can tuck sprigs of one or more of those plants under your pet’s bed cover (or under your rugs), or boil some of those herbs in water and pour the cooled water onto your pet, rubbing it into their coat. (Note: Some herbal or “natural” ingredients can cause allergic reactions or toxicity in animals. Be sure to test any treatment in a small dose first; and always apply treatments sparingly and only as needed. Also, never use pet products that contain pennyroyal oil, which is toxic to animals. Furthermore, while some sources say that adding a little bit of garlic to a pet’s diet will repel fleas, other reputable sources say that garlic can be toxic to dogs and even more so to cats, even in small amounts; so I steer clear of using garlic, just to be safe.) If your pet has a flea infestation that does not respond to any of the plant-based solutions listed above, look for the lowest-risk commercial products listed in the NRDC’s directory, which include Spinosad-based products, such as Comfortis.

    NRDC’s research has identified many common products that should be avoided, due to their high toxicity risks. According to the NRDC, such high-risk products currently include K9 Advantix II, and a number of products made by Hartz, Sentry, Sergeant, Vet-Kem, Adams, Bio Spot, Happy Jack, Verbac, Zodiac, and other companies.

    To take action on this issue, print out some of the info from the links below, bring it to your pet store and to your veterinarian, and ask them to stop selling flea control products that contain the most dangerous pesticides (and to start selling the lowest-risk products), to protect the health of pets and their people.

    The following are a few online stores that specialize in natural and non-toxic pet supplies. (Note: This list does not constitute an endorsement of any of these companies):

    Selecting Safe and Healthy Pet Foods

    I am a dog lover. Some people who know me might even say I’m a dog fanatic. (I like cats too, by the way. I don’t currently have one, but I have in the past and I’m sure I will again.) My husband and I consider our dog an integral part of our family, and we try to make sure we’re giving her the best sustenance and care that we can. Unfortunately, many pet foods are extremely low quality and don’t provide the proper nutrition to help pets live long and healthy lives. And some foods can even be harmful.

    Remember, a couple of years back, when a bunch of pets got painful kidney stones, and some died, because of melamine in their food?  (Click here and here to see current recalls and alerts.) Contaminants and chemical additives aren’t the only problems to be concerned about. Many popular pet foods are essentially junk food—the equivalent of feeding yourself low-grade fast food and nothing else, every single day.

    For some good overviews of the problems with many dog foods, and what types of foods to look for, you should read the following articles from DogFoodAnalysis.com (link 1; link 2), and the following articles by Dr. Weil, who’s not a vet, but rather an MD and a dog lover (link 1; link 2).

    My dog’s vet recommends Chicken Soup for the Dog Lover’s Soul and Natural Balance. Dr. Weil feeds his dogs Acana Pacific. And the Dog Food Analysis site has given its highest rating (6 stars) to certain product lines within the following brands: Innova EVO, Wellness Core, Instinct, Orijen, Taste of the Wild, Horizon Legacy, Artemis Maximal, Blue Wilderness, and Go Natural Grain Free Endurance. You can look up the DogFoodAnalysis review and rating of the food you’re currently buying for your dog by using the site’s Search bar. Many products that are marketed as healthy and beneficial, such as Purina’s “Beneful,” have received very bad reviews because they contain such low-quality ingredients. In fact, most of the dog foods that were reviewed ended up getting only a 1-star rating!  (Bear in mind that some of the reviews on the site are a couple of years old, so some brands may have changed their ingredients since then.)

    Some specialty stores, such as Pet Food Express (in the San Francisco Bay Area), have a large selection of some of the higher-quality food brands. But keep in mind that not all pet foods that are expensive (or that advertise themselves as healthful) are actually high-quality. Do your research to make sure you know what you’re getting.

    Words of the Wise: On Progress and Action

    Progress tends to take longer than we’d like. Change is almost always incremental: it happens through a series of steps (and sometimes it’s two-steps-forward, one-step-back), in part because many people are resistant to or fearful of change. However, small steps gradually lead to larger strides. Individual actions often have a ripple effect. And small changes made by growing numbers of people can add up to a big impact. We shouldn’t let ourselves get paralyzed into inaction or apathy because we feel overwhelmed by the magnitude of a problem or we think our actions won’t make a difference.

    Doing something constructive to address a problem is better than doing nothing. Wise thinkers throughout history—from Euripides to Lily Tomlin—have come to this conclusion, and they have articulated it in a variety of ways:

    [UPDATE: A few more quotations were added in July and September 2012.]

    “Slight not what’s near, when aiming at what’s far.” — Euripides

    “Nobody made a bigger mistake than he who did nothing because he could do only a little.” — Edmund Burke

    “The best time to plant a tree was 20 years ago. The next best time is today.” — Chinese proverb [click on link to see the quotation in graphic form]

    “Don’t judge each day by the harvest you reap, but by the seeds that you plant.” — Robert Louis Stevenson

    “The perfect is the enemy of the good.” — Voltaire

    “The journey of a thousand miles begins with one step.” — Lao Tzu

    “Pick battles big enough to matter, small enough to win.” — Jonathan Kozol

    “We must not, in trying to think about how we can make a big difference, ignore the small daily differences we can make which, over time, add up to big differences that we often cannot foresee.” — Marian Wright Edelman

    “I am only one, but I am one. I cannot do everything, but I can do something. And I will not let what I cannot do interfere with what I can do.” — Edward Everett Hale<strong

    “Act as if what you do makes a difference. It does.” — William James

    “The key to everything is patience. You get the chicken by hatching the egg, not by smashing it.” — Arnold Glasgow

    “The world changes according to the way people see it, and if you can alter, even by a millimeter, the way people look at reality, then you can change the world.” — James Baldwin

    “Never doubt that a small group of thoughtful, committed citizens can change the world. Indeed, it is the only thing that ever has.” — Margaret Mead

    “If you think you are too small to be effective, you have never been in bed with a mosquito.” —Bette Reese

    “Big problems are rarely solved with commensurately big solutions. Instead, they are most often solved by a sequence of small solutions.” — Chip Heath and Dan Heath (This statement is excerpted from their book, Switch: How to Change Things When Change Is Hard.)

    “Discontent is the first necessity of progress.” — Thomas Edison

    “I always wondered why somebody doesn’t do something about that. Then I realized I was somebody.” — Lily Tomlin

    New Books: Thriving Beyond Sustainability, and Fundamentals of Integrated Design for Sustainable Building

    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.

    Sustainable Neighborhoods and Communities: Certifications, developments, organizations, and websites

    Several certification programs have emerged to rate the sustainability of mixed-use, neighborhood and community-scale developments—addressing a wider range of issues than previous rating systems for individual buildings have addressed. These broader-scale certification programs include: LEED for Neighborhood Development, and the Living Building Challenge (Update: There is now also a Living Community Challenge program). The programs’ requirements can be used as planning and design guidelines for any project, even if official third-party certification is not the goal. There is also a non-certification framework called One Planet Communities.

    1. LEED for Neighborhood Development (LEED ND): LEED ND was developed as a collaboration between the U.S. Green Building Council, the Congress for the New Urbanism, and the Natural Resources Defense Council. LEED ND integrates the principles of smart growth, urbanism, and green building into neighborhood design. It aims to promote walkable, livable communities that reduce urban sprawl, decrease automobile dependence, provide housing close to jobs and services, and benefit environmental and public health. LEED ND credits are organized into the following categories: Smart Location and Linkage; Neighborhood Pattern and Design; Green Infrastructure and Buildings; Innovation and Design Process; and Regional issues.

    LEED ND can be applied to developments of all sizes, and it can be applied to new developments or redevelopment projects. The first official, post-pilot version of the rating system was released at the end of 2009. A project can be recognized at any or all of the following stages, depending on where it is in the development process:

    • Stage 1: Conditional approval of a LEED-ND plan, prior to entitlement. (This can help projects get support from the local government and community.)
    • Stage 2: Pre-certification of a LEED-ND plan for fully-entitled projects. (This can help projects secure financing, expedited permitting, or tenants.)
    • Stage 3: Certification of a project once construction has been completed.

    LEED ND pilot developments that have been constructed include: Solea Condominiums in Washington DC (Stage 3 Gold certified); Eliot Tower in Portland, OR (Stage 3 Silver certified); Excelsior and Grand in St. Louis Park, MN (Stage 3 Certified); Whistler Crossing in Riverdale (Chicago area), IL (Stage 3 Certified); and Celadon in Charlotte, NC (Stage 3 Certified). And a couple of notable LEED ND pilot projects that are well underway are: Dockside Green in Victoria, British Columbia (Stage 2 Platinum certified plan), and Tassafaronga Village in Oakland, CA (Stage 2 Gold certified plan).

    2. Living Building Challenge: Like One Planet Communities, this is an international program that has developed deep-green standards that go beyond LEED requirements. This certification system can be applied to projects of any scale: from an individual building to a neighborhood or community design project. (Update: A Living Community Challenge program has now been created, as well.)

    3. One Planet Communities: This is an international program that is part of the One Planet Living program developed by BioRegional, a UK-based environmental organization. The One Planet Living program is based on 10 principles in the following categories: zero carbon, zero waste, sustainable transport, local and sustainable materials, local and sustainable food, sustainable water, natural habitats and wildlife, culture and heritage, equity and fair trade, and health and happiness.  The first North American project to be endorsed by One Planet Communities is the 200-acre Sonoma Mountain Village in Rohnert Park, California. Sonoma Mountain Village is also registered as a LEED ND project. [Newer post, July ’15: One Planet Communities: Greener Villages and Developments]

    In addition to these programs, many organizations are working to advance the sustainability of neighborhoods and communities in a variety of ways. Two active organizations that are focused primarily on planning, design, and development include: Partnership for Sustainable Communities (for whom I recently did some research and writing) and Urban Re:Vision. A number of local, grassroots initiatives for community sustainability, resiliency, and energy independence—such as Transition initiatives—are also gaining steam around the country and the world. Update (added 4/21/10): For a searchable database of “ecovillages” around the U.S. and the world, see the Global Ecovillage Network website.

    Click here to download a more comprehensive listing of organizations and websites focused on sustainable communities (4-page, 80 KB PDF file – updated June 2010). The listing includes national, California-based, and San Francisco Bay Area resources.

    For other good info on sustainable communities, smart growth, and green neighborhood design and development, check out Kaid Benfield’s NRDC blog.

    In a later post, I’ll be covering larger-scale, municipal-level sustainable planning initiatives for entire cities and regions. Stay tuned.

    Recommended Film: The Cove

    If you haven’t seen it already, I’d recommend watching The Cove.  I’m not the only one who thinks it’s a good film. It has won dozens of film awards, and it was recently nominated for an Oscar for Best Documentary. (You can get it on Netflix, iTunes, or On Demand cable, or buy the DVD.)

    The Cove is suspenseful and riveting—reminiscent of a spy flick like Ocean’s Eleven—but it’s a documentary about real events: the authorized but carefully concealed killing of more than 20,000 dolphins (each year) in Taiji, a small town in Japan. The film has a brief segment of disturbing footage, but it is not overdone; and there’s beautiful and humorous footage, as well, to balance out the drama and tension.  For more information about the dolphin slaughter, or to take action against this practice, go to TakePart.com/TheCove. (Note: Mass dolphin killings also happen in Denmark’s Faeroe Islands.)

    The film also tells the compelling story of the personal, moral transformation of Ric O’Barry, the man who captured and trained the dolphins who were featured in the 1960s TV show Flipper, the popularity of which spurred the more widespread capture of dolphins to be used for human amusement and entertainment. After recognizing the folly and tragedy of these practices, O’Barry has dedicated his life to saving dolphins and releasing them from captivity.  For information on the captivity of dolphins for marine parks and swimming-with-dolphins programs, check out this Humane Society webpage.  And click here to see a funny and relevant cartoon from The New Yorker.

    A third important issue—an environmental issue—comes up in the film, as well: the high levels of mercury that are found in dolphins and in some types of fish, such as tuna. Mercury exposure can cause severe neurological impairment (EPA mercury webpage).  For more information on mercury contamination in seafood, marine life, humans, and the environment at large, go to this NRDC webpage or GotMercury.org.

    Towards the end, the film briefly touches on the issue of overfishing, which turns out to be one of the primary causes of the dolphin slaughter tragedy that the film has exposed. According to O’Barry, the dolphin-killing fishermen say they consider dolphins “pests” that are eating all of “our” fish. The fishermen use this to justify the slaughter, when in fact it is humans’ fishing practices (such as industrial-scale trawling operations), our high levels of fish consumption, and water pollution—as well as the damming of rivers, in the case of certain species of salmon—that are responsible for the steep decline and imminent collapse of many fishery stocks. For information on which types of seafood to avoid buying (due to overfishing and/or contamination issues), see the Monterey Bay Aquarium’s Seafood Watch site and download their Pocket Guide.
