Sears Tower to Get Green Retrofit
Stumble it!

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.

Oregon Home LeapFrogs Competition With 100% Sustainable Wood
The rewards of building green are many, but they often come with some frustrations on the side. One of the greatest challenges can be sourcing building materials - that great green design or green building certification might rely on materials that are very tough to find in your market.
Wood products are a case in point. If you insist on using only the best green wood in your project (wood certified by the Forest Stewardship Council, or FSC), then be prepared to run around a bit. You might be able to find FSC-certified core building materials such as framing lumber, flooring or decking at your local home improvement store, but you’ll likely be more challenged finding local sources of doors, windows, cabinets and finish materials.
With some hard work and a great contractor, though, it’s possible to use nothing but green wood, as shown by the 2008 winner of FSC’s “Designing and Building With FSC” award. Portland, Oregon builder Green Hammer, Inc. won the award after using nearly 100% FSC-certified wood in their LeapFrog project (the only exceptions were some limited materials salvaged from local buildings or milled from on-site trees). Among the wood products used were FSC-certified Douglas fir, hemlock and spruce from local forests for framing lumber, floor, trim and cabinets and FSC formaldehyde-free plywood. Best of all, Stephen Aiguier, president of Green Hammer, estimated that the use of FSC wood only added 1-2% to the cost of the project (via GreenSource Magazine).
The LeapFrog house is notable for many other reasons as well, among them its LEED Platinum rating from the USGBC. Some of the other non-wood highlights include:
- Geothermal heat pump for radiant floors and panels, and domestic hot water;
- Advanced framing techniques (staggered studs) that minimize thermal bridging in the walls and allow for an uninterrupted layer of insulation;
- Rainwater catchment system with purification that provides 100% of the home’s water needs (wow!);
- “Cool” metal roof without any plumbing or ventilation penetrations - energy efficient, offers the possibility of lasting for 100 years, and assists in funneling clean water to the catchment system.
Oh, and if your interest has been piqued AND you happen to live in the Portland area, there’s one for sale! The $690K pricetag is a bit steep, but I’m sure the huge energy and water bill savings with this home will take a big chunk out of that through time.

The 10 Dumbest Green Buildings on Earth
Written by Alex Felsinger, courtesy of Green Building Elements.com
While any structure built in a way that lessens its footprint is welcomed, some of the buildings that people try to turn green simply make no sense.
LEED certification, in all its greatness, does not take the building’s intended purpose into account; this leaves us with some hilarious, unabashedly self-contradicting buildings. Here are the ten of the most laughable green buildings:
1. BP’s Helios House Gas Station - Los Angeles, Cal.
Yes, there is an LEED-certified gas station. It’s actually a nice building, complete with rainwater collection, solar panels, recycled building materials, and LED lighting. However, don’t think you’ll be able to refuel with biodiesel or charge up your electric car—they’re only in the petroleum-dealing business. How green of them, right?
2. Justin Timberlake’s Golf Course/Lodge - Woodstock, Tenn.
So Justin Timberlake decided that he wants to buy a golf course and fix it up with an LEED-certified lodge. While it’s an improvement compared to most other golf courses, the fact remains that maintaining a golf course takes chemicals and lots of water. In the United States alone, golf courses total more than 1.7 million acres and consume around 4 billion gallons of water every day. How does a green lodge counteract the water used to maintain the course? Justin, if you really want to be green, you should have turned it into a wildlife sanctuary instead.
3. Nestle Pure Life Water Bottling Plant - Boiling Springs, Tenn.
While this isn’t the only LEED-certified water bottling plant, it’s listed for having the most greenwashed name. Ozarka, Arrowhead, Ice Mountain, and Deer Park water bottling plants also have LEED certifications of some sort, but they couldn’t compete with Pure Life in the name department. If anyone needs a reminder of why bottling water is a bad idea, here are five reasons to ditch the bottle. Oh, and Nestle as a whole won’t be getting an award for their treatment of the planet and its people any time soon.
4. Logan Airport Terminal A - Boston, Mass.
Activists in England have put their freedom on the line protesting against a third runway at the enormous Heathrow Airport; do you think they’d be more satisfied with the runway if the airport terminal was LEED certified, with solar panels and the whole bit? You’d be right to assume they wouldn’t, because whether they take off from a green building or not, airplanes are still one of the top causes of global warming.
5. Toyota Car Dealership - Rockwall, Tex.
While Toyota is almost synonymous with green when it comes to cars, in reality they’re not much better than any other car company. They have a full line of vehicles, including four-wheel-drive SUV’s, some of which are 8-cylinder. In fact, their entire fleet’s average gas mileage is worse than Chevrolet’s. Perhaps they should clean up their cars before trying to green their dealerships?
6. Antilia Tower - Mumbai, India
While this probably will not be LEED certified, it has been often mentioned as being one of the greenest building concepts on the planet. While it does look beautiful and will act as a giant carbon sink in the middle of the city, there’s a major problem: it will be the home of one family. No matter how green this building is, that is a complete waste of space in a city known for its overcrowding.
7. Civic Center Parking Garage - Santa Monica, Cal.
The only green parking garage I want to see would be located at a train or bus station for people to drop off their cars to finish their commute on mass transit. To quote every politician involved in the 2008 campaign, “You can put lipstick on a pig, but it’s still a pig.”
8. Vacation Home Development - Las Vegas, Nev.
You only need one house, people! Granted that seven of these eight homes are 1/12 shares, these homes are being built in a desert (Las Vegas) and if anyone needs a water-capture system, it’s people who live there year-around. Simply due to their excess, vacation homes may be the least environmentally-friendly structures on earth.
9. Spaceport America - New Mexico
Another case of the rich attempting to make the rest of us think they’re doing the world a favor. Recreational space travel, at least with the current technology, is a huge and unnecessary carbon polluter. But hey, the spaceport will be LEED certified, so everything’s going to be fine, right?
10. Every Fancy New Building - Dubai, United Arab Emirates
I know, I know — I cheated on this one. I couldn’t pick just one since they’re all ridiculous for the same reason. The government is intent on making Dubai one of the biggest, most gaudy places on earth. Perhaps to compensate for unending excess, they’ve mandated that all new buildings must have specific eco-minded properties, but when you take all of it in at once, you know it’s nothing but a giant waste of resources.

Top 10 EcoPrinciples for Communities
Written by Keith Rockmael, courtesy of GreenBuildingElements.com
With the economy in turmoil, a real estate prices dropping, green communities and green building will become more important. It’s easy to see how broken our current community model is in terms of the urban sprawl; the average American commute continues to grow longer. Between 1969 and 2001, the number of vehicle miles traveled for commuting jumped from 4,180 to 5,720.
The Sierra Club notes that today’s average American driver spends what amounts to 55 eight hour workdays behind the wheel every year. Gas won’t stay at the current level so we need to look at developing more sustainable communities.
San Francisco area architect Michelle Kaufmann and Kelly Melia-Teevan came up with a top 10 (sorry Letterman) EcoPrinciples for Communities.
1. Smart Design
Some architects play God; instead of working with nature they go against it. Building orientation remains a big, no cost key, as well as designing to use less, and to collaborate with the landscape.
2. Energy Efficiency
Kind of a no brainer here. Everyone from Obama on down seems to be talking about energy efficiency. While some aspects remain somewhat pricey such as photovoltaic systems, other energy saving methods such as passive solar layouts, sealing building envelopes with super efficient insulation and glass and harnessing alternative energy sources offer not only a decent ROI but save the Earth’s resources as well.
3. Water Conservation
Here in the Bay Area we are headed for a drought. Ideas for water savings include basic ideas such as xeriscaping. Who needs a lawn anyway? Sculpting bioswales into the land, irrigating with rainwater catchment systems and paving with only pervious ground surfaces can conserve gallons without much added cost.
4. Reduce Waste
As one of the Three R’s, Kauffman suggests designing easy to access, easy to use recycling centers. How smart can it be to drive with a plastic bag of aluminum cans to the faraway recycling center? Also, she offers ideas such as integrating on-site composting, and facilitating “living machines” (engineered waste treatment system designed to process a building’s sanitary drainage on-site).
5. Healthy Environment
Everyone seems to forget this area in terms of Green Building. It won’t do much good to maintain a clean environment but have sick people living in unhealthy homes. A sustainable neighborhood will offer easy access to exercise, encourage cooking classes and establishing on-site food production instead of driving to some fast food joint for a completely unsustainable meal.
6. Diversity
Cities such as San Francisco thrive because of the richness of diversity. A sustainable community will create an assortment of residents from different backgrounds, ages and cultures. The housing will offer both market rate and affordable rate housing options.
7. Smart Location
The name says it all. Kauffman suggests building and designing for environmental, social, and economic benefits. Might builders think about building near easy access to mass transit and choosing areas near sources of quality food? Is that too progressive?
8. Respect the Land
Something that seems to have disappeared from the vocabulary – r-e-s-p-e-c-t. That’s right just like Aretha. New green communities would protect the existing landscape and ecology by adopting functional, comfortable density, minimizing site disturbance and protecting biodiversity by maintaining native ecosystem.
9. Smart Auto Strategy
As much as we’d like to rid ourselves of cars completely it just isn’t going to happen. However, we can lessen the intrusion and impact of automobiles in communities by implementing smart parking requirements, and separating parking streets from pedestrian streets and bike lanes. Constructing more narrow streets in an effort to encourage walking and biking rather than driving isn’t rocket science.
10. Shared Resources
Create more community within the community (see how that works) by introducing resource sharing (bikes, cars, tools, garden equipment, child care), establish community victory gardens, and building playgrounds, parks, athletic fields, picnic areas, etc rather than just concrete jungles.
Let the greening begin.

Green Tax Credits Available in 2009
Written by Dawn Killough, courtesy of Green Building Elements.com
(NOTE: We’ve just published an update (as of March 2 2009) on some of the tax credits included in the final stimulus bill here.)
As was previously reported on Green Building Elements, Congress was contemplating how to include the continuation of energy efficiency tax credits in the “economic bailout.” Well, they did it, and even managed to increase some of the incentives.
Here is a brief run-down of the credits available in 2009:
* Purchase of hybrid car or SUV: $250 to $3,150, depending on vehicle weight and fuel economy.
* Purchase of central air conditioner or heat pump: $300, only some Energy Star products qualify.
* Furnace or boiler: $150, only some Energy Star products qualify.
* Windows: up to $200, all Energy Star windows qualify.
* Insulation and sealing: up to $500, must meet model building code as installed.
* Ground source heat pump: up to $2,000, only Energy Star models qualify.
* There is a limit of $500 in tax credits for home improvements.
Homeowners should also check the DSIRE website for applicable state tax credits.
Businesses can also get in on the act. They are eligible for the hybrid vehicle incentives and incentives for energy efficient buildings. Businesses that sell new energy efficient homes (through 2009) or efficient appliances (through 2010) can take tax credits on these products that may reduce the cost to consumers.
For more on tax credits for businesses, builders, and consumers, see Tax Incentives Assistance Project, or The Alliance to Save Energy. Of course, you should check with your tax preparer for more information on how these credits effect you, and what paperwork needs to be completed.

Berkeley Architect Constructs Self-Heating Home
Written by Becky Striepe, courtesy of EcoLocalizer.com
A California architect has constructed a home that heats itself from the warmth of its appliances. Homes like this have been popular in Germany, where a local architect built the first of its kind in 1991, but they are only just starting to catch on here in the States.
Nabih Tahan’s “Passive House” on Grant Street in Berkeley is the first one in California. It uses a ventilator to recycle the heat that radiates from the appliances, reducing the use of heat from fossil fuels by 80%-90%.
Passive House Design
In order to utilize ambient heat from appliances, the house needs to be incredibly well insulated. It’s essentially air tight, allowing the ventilation system to trap the heat and distribute it throughout the home. Passive homes have specific design requirements, such as “superinsulation” and superwindows.
It would be extremely expensive to retrofit a house as a passive house, making it more suited to new construction or a home that is undergoing a massive renovation. Even with the energy savings, it would take a long time to break even on the investment with a retrofit. The architect behind the passive house in Berkeley said:
By doing smaller insulating renovations, you can improve energy consumption and you’ll definitely make a difference. But to get to Passive House standards, you really have to either rip out the outside or the inside of the house.
Improving Your Own Home’s Energy Usage
Homeowners can still take some lessons from passive house construction, even if they can’t afford a huge renovation. According to the US Department of Energy, over 1/3 of Americans’ energy bills goes towards heating their homes. Something as simple as sealing cracks around doors and windows can make a big difference in the amount of electricity or gas you’re using to keep your home warm. Many power companies provide cheap or even free home energy audits to help determine where you need additional sealing and insulation. There are a number of inexpensive things you can do to improve your home’s efficiency.
