Living Zero Homes Tour Coming Near You
Stumble it!
Tour Locations for the Living Zero Home Tour
Want to get a first hand glimpse of a net-zero energy home that generates all its necessary power from renewable energy? You may get a chance if you live in one of the areas that the Living Zero Home Tour is traveling through. Starting just a week ago in Chicago, the Living Zero Home Tour is showcasing a net-zero energy home featuring energy efficient appliances and building technologies. The home will continue to travel through November so you can experience and see for yourself how energy efficient technologies are integrated and how they can easily lower monthly utility bills as well as your reduce environmental impact.

California Architect Thinks About White Roofs
Written by Susan Kraemer, courtesy of GreenBuildingElements.com
If every building had a white roof, we would be able to cool the surrounding areas. That is the reasoning behind a California law about to go into effect next month requiring light reflective roofs on all new buildings. It is already the law for new flat roofs here.
Here, architect Richard Meier and his partner Michael Palladino have apparently created a design to go one further. It’s entirely white; roofs, walls, and interiors.
So this luxury design of a cool and airy Southern California beach house is glamorous and climate friendly.
Well, no. The McMansion-sized size of the thing at 4,280-sq.-ft is not so planet friendly; because it takes more energy to heat and cool a larger space. But this house would be well suited for a ground heat exchange to passively heat and cool itself with 55 degree air cooled from 10 feet under the ground.
As architects in California get closer to 2020, they will need to think more about passive cooling and heating and zero energy houses, as that will be the law by 2020. All new building must be zero energy by then.
Incorporate solar roofing on the white roof, and this could be a zero energy house.
The blue of a solar roof would visually extend right out to the ocean. (And conceal that horrible mess of mechanical contraptions on that roof.) White elastomeric cool roof paint under the solar panels would help cool the modules making them more efficient on hot days.
But are architects thinking about these things?
With 2020 almost upon us: “The beams at the roof, located above the horizontal framing, express the structural rhythm and layering of components,” explains the architect. “This cadence is repeated with the joinery of the painted aluminum exterior wall panels and modular windows. The mass of the exterior plaster walls are juxtaposed to the transparent glazed facades, creating a mosaic of layered materials.”
Blah, blah, blah.

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!

8 Easy Ways to Save Energy and Money This Summer
The heat of summer is upon us, and that means folks are cranking up the AC, making an extra batch of ice, and generally burning energy 24-7. But we need all need to continue to try to conserve as much energy as possible to save resources and slow the march of global warming. And we get to save money at the same time– nice one!
Here are the eight easy things we can all do at home to cut our energy consumption.
1. Keep your home at an eco-conscious temperature. 78 degrees is plenty cool in the house. Turn down the AC and get a programmable thermostat so you’re only cooling the house when you really need to.
2. Work with the sun to keep your house cool. Close all shutters and blinds during the day to keep the sun out– then open windows at night to cool the house and feel the breeze (if you have any!).
3. Let the air dry your dishes and clothes. The dryer and dish washer use a lot of energy– and the air does the drying job just as well. Plus your clothes will last longer. See some great clothes-drying racks here.
4. Take shorter showers and do not take baths. Hot water heating is one of the major uses of energy in any home. Showers are the way to go– and keep ’em short. Baths use much more water and heat than do baths (unless you’re taking 30 minute showers!). You can also look into solar hot water.
5. Ditch the beer fridge. It’s amazing how many homes have two refrigerators. Please do not use more than one fridge. And if you have an old model, get a newer Energy Star model.
6. Use ceiling fans rather than AC. They are much more energy-efficient and you can get very reasonably priced Energy Star models.
7. Get solar screens for your windows. These screens cut 75% of the heat coming through your windows, but don’t impact your visibility. They are really great energy savers. See solar screens here.
8. Spend one night each week in candlelight. It’s romantic, fun and inspires new conversation. If you’ve got kids, how about turning off the TV one night and playing a board game by candlelight? Clue would be particularly spooky!

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.
