Weekend Projects to Save Water in Your Backyard
Stumble it!
We know we need to save water, no really we know, but sometimes we just need a little encouragement to get beyond the low hanging fruit. It is fairly easy to install low flow faucets and showerheads in the house, conserve more, and take shorter showers, but when it comes to saving water outdoors, that’s another story. In most backyards, sprinkler systems were installed well before saving water was a huge issue like it is now, so systems are inefficient and wasteful. With enough time, money and work you could fully replant your yard with drought tolerant plants, rip out your lawn and install a highly efficient irrigation system. If you don’t have the time for that, here are a couple backyard projects you can tackle soon, like this weekend or this month. (more…)

Celebrate Independence Day the Eco Way!
This weekend is the Independence Day holiday– and that means we’ll be lighting up the BBQ, consuming beverages, throwing out paper plates and generally wasting resources while we enjoy ourselves. So we’ve come up with a list of easy things you can do to lower the environmental impact of this fun, important holiday. It’s Independence Day, the Eco Way!
1. Light that BBQ with Propane. Wood and charcoal may seem like more natural fuel sources, but propane burns cleaner. You’ll have less smoke and less of a challenge keeping a fire going. Make sure that you refill or recycle your propane tank once it’s empty.
2. Use reusable plates and cups– or use recycled and/or biodegradable ones. Think of all of the millions of plastic and paper plates and cups being tossed out this weekend! It’s scary. You can really help out by either using sturdy, reusable plastic-ware and washing it after use. Or you can get compostable and biodegradable tableware that are great and will make an interesting conversation point for your event!
3. Put out a clearly-labeled recycling bin next to the trash basket. Make it clear to people that “this is the bin for your cans, bottles, plastic cups, etc.” If you make it easy for people, they will do it. And you won’t have to sort stuff at the end of the party!
4. Use tap water rather than bottled water. We know it’s hot, and bottled water is easy, but just fill some big pitchers up with water for people. You’ll cut your plastic use in a big way.
5. Skip the at-home fireworks. Naturally something that explodes, creates lots of light and leaves a cloud of smoke also comes with pollution. Fireworks also release heavy metals like lead into the air. Leave the fireworks to the professionals.
6. If you’re planning to go to the beach, know the condition of the beach before you go. Check out Beaches911.com to learn about the health conditions of the beach, any beach closures, and also eco-smart boating tips.
7. If you are taking a road trip of any kind, make sure to maximize your gas mileage. You could either rent a hybrid if you don’t have one– or make sure your tires are well-inflated, keep the AC as low as possible, and follow these tips for how to green your road trip.
Have a safe, healthy, fun holiday!

Sears Tower to Get Green Retrofit
Courtesy of Environmental News Network and Reuters
The tallest building in the Western Hemisphere will undergo a $350 million “green” retrofit that its owners said on Wednesday will make the 110-story office tower a beacon for environmentally sound space.
Plans call for the 1,450-foot Sears Tower to reduce its electricity consumption by 80 percent and water usage by 40 percent. It will be renamed the Willis tower later this summer in a deal with new tenant global insurance broker Willis Group Holdings.
To achieve the savings, owner American Landmark Properties and its partners plan to:
- Replace the 1973 tower’s 16,000 tinted single-pane windows and create a “thermal break” between Chicago’s frigid winters and hot summers and the interior.
- Install gas boilers equipped with fuel cells, which generate electricity, heat and cooling.
- Revamp the tower’s 104 elevators and 15 escalators to cut their electricity usage by 40 percent.
- Conserve 24 million gallons of water with new restroom fixtures and “condensation capture.”
- “Harvest daylight” by installing systems that automatically dim lighting based on available natural light.
- Install solar panels to heat water.
- Erect wind turbines on building setbacks, if possible.

Green Remodel Thoughts Straight From The Toilet Tank
I recently had the good fortune of participating in a New York Times piece (published in the Home section today) on green home consultants. After a few hours of in-home work and many more of analysis, reporting, product research and follow-up with my clients, it was somewhat ironic that the lead image for the story was a picture of me peering into the tank of a toilet!
One could argue a toilet is a fitting representation of our times, after all. The economy remains in the tank, we continue to do relatively little as a society to combat climate change, and the residential green sector continues to dragged down by the horrible housing market (unless you happen to be in one of the few sectors directly benefiting from stimulus funding).
However, we still see a very bright future for the overall green remodeling/retrofit market. The lowest hanging fruit on the path to a lower-carbon economy lie in our homes, from weatherization to low-flow water fixtures to efficient appliances and lighting. The environmental savings can be significant, and many projects will start contributing to your bank account in less than a year. Although each of our individual actions might be a drop in the bucket (as noted by some of the skeptical folks interviewed in the Times article), our collective actions will amount to significant change and send a message to both companies and our elected officials that the old way won’t work anymore.
The first step is getting started, of course, and a good green consultant can help by explaining both the environmental and economic benefits of particular green projects. Even with that information, a long list of recommendations can be pretty hard to digest. As a result, we always recommend that projects be tiered in a way that puts the ones where you get the most bang for your buck first. Tackle green projects in these four groups, and we guarantee that you’ll soon be on a logical and profitable path to a lower impact:
- Make the easy fixes that have high environmental and economic benefits first. Many first steps can be done for $0 - $100, and can cut major chunks out of your energy, water and carbon footprints. Good examples include turning down the temperature on your water heater, replacing inefficient lighting, installing low-flow water fixtures, sealing leaks and drafts and installing a programmable thermostat.
- Swap out key house systems, starting with the biggest hogs and/or systems that have multiple impacts. Once you’ve cut your baseline down based on #1, turn to these bigger projects. Great places to start are the water heater and furnace, since they influence the energy use of everything downstream, and the clothes washer, since it consumes both water and energy and produces greenhouse gases and wastewater.
- Install sustainable systems where possible for remaining water/energy needs. By now, you’ve probably cut your energy, water and sewer bills by 30-50%. But there’s a huge added benefit to this tiering of projects: you’ve also reduced the cost of major sustainble system upgrades. These projects, like solar panels, solar hot water heaters, wind turbines, graywater systems and rainwater capture/reuse systems, will be as much as 50% less expensive if they follow the projects in Tiers 1 and 2!
- Offset the rest. In most existing homes, it’s nearly impossible to competely cut your outside energy use and associated carbon footprint. Buy offsets for this remaining piece. We believe it’s always best to cut your own carbon footprint first rather than paying someone else to do it via offsets, but they’re a great solution for those stubborn emissions that elude even the most eco-committed of us.
Of course, a consultant isn’t necessary for any of this. Many websites offer great resources to help you sort through the options. And many online tools like our Environmental Impact Calculator can help you estimate the savings of green home projects, both environmental and economic, so that you can create a prioritized list based on your home’s unique characteristics.
Oh, back to the toilets. Toilet leaks can be huge water guzzlers, and I see leaks in as many as 10% of the homes that I visit. In this case, though, they were in perfect working order!

Get Ready for Sustainable Summer Fun!
Happy June everyone! We’re eager for summer to arrive– aren’t you? There are many things we can all do to ensure that we have a fun, eco-friendly summer. Read on and get that barbeque apron at the ready!
What You Need to Know Before You Mow
As the grass grows longer, we get the mower ready to go to work. You will probably be shocked to learn that gas mowers are MAJOR environmental offenders. According to the California Air Resources Board, lawn mower engines contribute 93 times more smog-forming emissions than do cars on a gallon-for-gallon basis. The pollution from a year’s use of an average gas-powered lawnmower is equivalent to the pollution from driving a car 86,000 miles. YES, it’s that bad. And some chainsaws and trimmers are even worse.
So please consider ditching your gas mower and getting either a battery powered or push mower. This Brill Luxus 38 push mower gets great ratings for usability and effectiveness. And there are some great cordless electrical mowers here, too.
Don’t Be an Enviro-Hog at the BBQ
When we have a summer BBQ, most of us generate a pretty impressive amount of waste. You can cut down on the trash going to the land fill in several easy ways. First, make sure to put out two trash cans: one for the food junk and one for recyclable glass & cans. As you know, if you don’t have a separate can, people will dump all of their cans and bottles right in with the other trash. If you don’t have a second can, then put out a cardboard box and write RECYCLE on it. Then you can toss the whole box in the recycling bin after the party!
Next, don’t use traditional paper plates and plastic utensils. Get yourself some compostable and biodegradable alternatives. These are just as functional as the plastic/paper kind but will decompose over time. Or if you don’t want to go that far, look for paper plates and napkins made out of recycled materials.
And what about the left-over veggies, salad and buns? You know where those go–right into your handy composter, to make healthy mulch for the garden.
Be Water-Wise this Summer
Don’t forget that water is one of our most valuable natural resources. In the Western US this summer we’ll be facing a fierce drought, given what little rainfall we’ve had so far this year. Please be sure to conserve water by 1) watering only in the early morning when the sun and evaporation are lower and 2) adjusting your sprinklers so that they only water your yard and not your driveway or street.
With all of the outdoor recreation and beach trips, showering can increase over the summer. Save as much as 40% of your water and energy per shower with this new Delta Fluidics showerhead that offers low-flow efficiency and high-flow comfort.
Cool It with a Ceiling Fan
Energy Star ceiling fans are much more efficient than air conditioners and can cool your house by a few degrees or more. Run a ceiling fan instead of AC whenever you can, and even if you do run AC, run it at a higher temp and use the ceiling fan to recirculate the cool air. See our selection of Energy Star ceiling fans here.

Water from Melting Greenland Ice Sheath May Impact Northeast US Coast
From the Environmental News Network (ENN.com)
New research by the National Center for Atmospheric Research points to the possibility that water from the melting Greenland Ice Sheath could change oceanic circulation in the North Atlantic, in a way that would raise sea levels off the Northeast by about eight inches more than the average global sea level rise that is expected with global warming.
Results of the study are being published this week in Geophysical Research Letters. They suggest that moderate to high rates of ice melt from Greenland may shift ocean circulation by about 2100, causing sea levels off the northeast coast of North America to rise by about 30 to 51 centimeters (12 to 20 inches) more than other coastal areas.
The research builds on recent reports that have found that sea level rise could adversely affect North America, and its findings suggest that the situation is even more urgent than previously believed.
“If the Greenland melt continues to accelerate, we could see significant impacts this century on the northeast U.S. coast from the resulting sea level rise,” says scientist Aixue Hu, the paper’s lead author. Hu is at the National Center for Atmospheric Research (NCAR) in Boulder, Colo. “Major northeastern cities are directly in the path of the greatest rise.”
To assess the impact of Greenland ice melt on ocean circulation, Hu and his coauthors used the Community Climate System Model, an NCAR-based computer model that simulates global climate.
They considered three scenarios: the melt rate continuing to increase by 7 percent a year, as has been the case in recent years, or the melt rate slowing down to an increase of either 1 or 3 percent a year.
