Old Buildings, New Life

The shift from building new commercial spaces was bound to turn from erecting sparkling new mega-buildings on greenfields to retrofitting run-down but still valuable older buildings in good locations close to transportation or other amenities.

No one knows this better than the U.S. Green Building Council (USGBC). Its LEED green building certification is often called upon to rate these buildings. To date, more than 40,000 projects participate in the commercial and institutional rating systems of USGBC, which represents 7.9 billion square feet of construction space.

Ashley Katz, communications manager for USGBC notes that many of these commercial ratings are for existing buildings. “LEED for Existing Buildings: Operations & Maintenance has seen explosive growth since 2008. More certifications are awarded under [the existing buildings program] on a square-footage basis than any other LEED rating system. And this is important because existing buildings make up the vast majority of the U.S. building stock.”

As a result of this growth, LEED projects are predominately existing buildings that have received certification based on verified energy performance. “We believe that the rapid uptake of this tool signals that the market is becoming increasingly aware of energy performance and is ready to move further toward even higher levels of performance,” Katz says.

USGBC’s experience is backed up by research. The McKinsey & Company report, “Unlocking Energy Efficiency in the U.S. Economy,” which addresses reducing U.S. greenhouse gas emissions, states that existing buildings will make money and will meet 85% of our new energy demand through 2030.

And the 2009 McGraw Hill Construction’s “SmartMarket Report” estimated that the green building retrofit and renovation market was 5%–9% by value, or a $2–$4 billion marketplace for major retrofit projects. By 2014, that share is expected to increase to 20%–30%, representing a $10–$15 billion market for major projects.

Katz points out the Adobe Systems project in Northern California as particularly representative of the retrofit commercial projects and why they are growing and will continue to grow: Adobe spent $1.4 million on 64 separate projects and received $389,000 in rebates, $1.2 million in annual savings, reported a 10-month payback, and 121% ROI.

These kinds of numbers are valuable for companies that need to see a strong ROI and must defend spending in a still-recovering economy.

Another example of a retrofit with a solid bottom line is the Armstrong World Industries’ corporate headquarters in Lancaster, Pa. Originally constructed in 1998, the glass and steel building was recently rehabbed for $138,000. Company leadership believes it will recoup that money in three years. For its outlay of money, the company got:

• waterless urinals, dual-flush toilets, and water sensors for the faucets so the company could greatly reduce its water footprint. Those changes and a fix to the humidification process reduced the annual use of water from 800,000 to 420,000 gallons
• occupancy sensors
• the purchase of 2 million kWh of wind power, which provides 75% of the project’s electricity use
• landscape with low-maintenance plants, no irrigation, and a catch basin that slows stormwater release.

Another project, the Joe Serna Jr. California EPA Headquarters Building in Sacramento, Calif., studied its investment in LEED Platinum certification and found it had increased its asset value by $12 million (for a $500,000 investment), while diverting 200+ tons of waste from the landfill and enjoying a building that was better than a third more energy efficient than California’s 1998 energy code.

The team for that project actually took on some untraditional methods, such as a vermicomposting program (worm composting), which diverts more than 10 tons of waste from landfills, and saves $10,000 annually. Plus, by eliminating garbage can liners and using reusable cloth bags in centrally located recycling bins, the headquarters saves $80,000 per year.

While success stories abound in the retrofit of existing buildings, some pundits warn of the potential “post-fossil-fuel age,” where many commercial buildings, high-rise buildings in particular, will be hard to maintain and may be abandoned for easier to maintain buildings.

In an interview with with Grist.com’s Kerry Trueman, James Howard Kuntsler, author of The Long Emergency, among many other books, warns of the impact of a capital scarce, energy-scarce future on mega-structures, which serves as a reminder that builders and owners must consider how buildings will weather an uncertain future where materials or energy might be scarce or expensive.

“The skyscraper is obsolete,” Kuntsler claims. “The main reason we’re done with skyscrapers is not because of the electric issues or heating-cooling issues per se, but because they will never be renovated! They are one-generation buildings. We will not have the capital to renovate them—and all buildings eventually require renovation. We likely won’t have the fabricated modular materials they require, either—everything from the manufactured sheet-rock to the silicon gaskets and sealers needed to keep the glass curtain walls attached.

“From now on, we need desperately to tone down our grandiosity. … Our cities have attained a scale that is inconsistent with the economic and energy realities of the future. The optimum building height, we will re-discover, is the number of stories most healthy people can comfortably walk up.”

LEEDing States

USGBC just released its list of top ten states in the United States for LEED-certified projects in 2010.

The top LEED states per capita, including the District of Columbia:

• District of Columbia: 25.15 square feet
• Nevada: 10.92 square feet
• New Mexico: 6.35 square feet
• New Hampshire: 4.49 square feet
• Oregon: 4.07 square feet
• South Carolina: 3.19 square feet
• Washington: 3.16 square feet
• Illinois: 3.09 square feet
• Arkansas: 2.9 square feet
• Colorado: 2.85 square feet
• Minnesota: 2.77 square feet

Of the projects represented on the list, the most-common project type was commercial office and the most-common owner type was for-profit organization. The cities most represented in the list were Chicago and Washington, D.C.

The Better Way to Know if a Building Is Green

An exhibit at the American Institute of Architects headquarters shows off the LEED for Neighborhood Development rating system

The architecture firm Farr Associates, the Chicago Architecture Foundation, and the U.S. Green Building Council have produced a fantastic exhibit on how to create green neighborhoods. It opened in Chicago last year and is now on display at the American Institute of Architects headquarters in Washington.

This carries some symbolism. When it comes to sustainable communities, the architecture profession has been both hero and villain. It has been a hero because many of the early (and continuing) leaders of smart growth and sustainability in our built environment have been architects, from William McDonough to Peter Calthorpe, from Andres Duany to David Dixon. Frankly, in my opinion, architects were way ahead of the environmental community in forging solutions to sprawl. And it’s a good thing that they were, because they gave us environmentalists something positive to advocate.

Winners of the 2011 Skyscraper Competition

eVolo magazine has run a tidy little competition for the last five years, inviting architects to innovative new skyscraper typologies. Today, the winners of the 2011 Skyscraper Competition were announced and we’ve got a recycling wind turbine, an energy- and water-harvesting horizontal tower, and a re-imagining of the Hoover Dam.

Jury members included SOFTlab principals Jose Gonzalez and Michael Svizos, architecture critic John Hill, Mitchell Joachim of Terreform One, CarloMaria Ciampoli of Live Architecture Network, and a host of other working and teaching architects (see the full list here).

FIRST PLACE: ‘LO2P Recycling Skyscraper’ by Atelier CMJN (Julien Combes, Gaël Brulé)

“The idea behind this skyscraper is to recycle the old cars and use them as building material for the new structure. The building is designed as a giant lung that would clean New Delhi’s air through a series of large-scale greenhouses that serve as filters. Another set of rotating filters capture the suspended particles in the air while the waste heat and carbon dioxide from the recycling center are used to grow plants that in turn produce bio-fuels.”

SECOND PLACE: ‘Flat Tower’ by Yoann Mescam, Paul-Eric Schirr-Bonnans, and Xavier Schirr-Bonnans

Imagined for medium-size cities where vertical skyscrapers do not fit the skyline, the flat tower is a “new high-density typology that deviates from the traditional skyscraper. The medium-height dome structure is perforated with cell-like skylights that provide direct sunlight to the agricultural fields and to the interior spaces. The dome’s large surface area is perfect to harvest solar energy and rainwater collection.”

THIRD PLACE: ‘Reimagining the Hoover Dam’ by Yheu-Shen Chua, United Kingdom

This project merges the programs at the current Hoover Dam — viewing platform, a bridge, and a gallery – into a “single vertical super structure.”

There a long list of honorable mentions, and we’ve highlighted below some especial favorites (clockwise from top left):

‘Sports Tower’ by Sergiy Prokofyev and Olga Prokofyeva, Ukraine

‘RE:pH Coastscraper’ by Gary Kellett, United Kingdom

‘White Cloud Skyscraper‘ by Adrian Vincent Kumar and Yun Kong Sung, New Zealand

‘Seeds of Life Skyscraper’ by Mekano (Osama Mohamed Elghannam, Karim Mohamed Elnabawy, Mohamed Ahmed Khamis, Nesma Mohamed Abobakr), Egypt

‘Waste Collector Skyscraper’ by Agata Sander and Tomek Kujawski, Poland

‘Hopetel: Transitional High-Rise Housing’ by Asaf Dali, United States

Architectural Landmark Near Completion as Cesar Pelli Tops Out Red Building at Pacific Design Center

LOS ANGELES, March 1, 2011 /PRNewswire/ — Cesar Pelli celebrated a milestone for the Red Building on Monday, as the long-awaited final building of the Pacific Design Center nears completion. The Red Building is the third building of the landmark West Hollywood showroom-and-office complex whose design and construction span nearly 40 years.

(Photo: http://photos.prnewswire.com/prnh/20110301/NE56547 )

At a topping-out ceremony, the architect joined developer and owner Charles S. Cohen to put in place a piece of red glass that completes the Red Building’s narrow triangular facade on San Vicente Boulevard. The 400,000-square-foot office building is slated for occupancy by year’s end.

“I am delighted to see the Red Building so close to fruition,” said Pelli, Senior Principal of Pelli Clarke Pelli Architects. “To know that the Pacific Design Center will soon be how I envisioned it is very exciting.”

Pelli conceived the 14-acre site to contain three buildings arranged around a plaza. The first, nicknamed the Blue Whale, was designed when Pelli was with Gruen Associates and completed in 1975. The Green Building, designed with his own firm, now Pelli Clarke Pelli Architects, followed in 1988.

The most dynamic of the three, the Red Building is composed of two curved, sloping towers atop seven levels of parking. Between the towers will be a courtyard planted with palm trees. The six-story West Tower slopes inward against the Hollywood Hills. The eight-story East Tower curves upward.

The ceremony also paid tribute to the “Los Angeles 12,” a group of Southern California architects featured in a 1976 exhibition at the Blue Building. Pelli, Roland Coate, Raymond Kappe, Daniel Dworsky, Craig Ellwood, Frank Gehry, John Lautner, Jerrold Lomax, Anthony Lumsden, Leroy Miller, James Pulliam and Bernard Zimmerman were in the original show. Eric Owen Moss and Michael Maltzan we also recognized at the ceremony.

A green answer to Vanity Fair’s architecture poll has its own blindspot

Renzo Piano's California Academy of Sciences in San Francisco. Credit: Tim Griffith.

When Vanity Fair recently released the results of a survey ranking the most significant pieces of architecture of the last 30 years — with Frank Gehry’s Guggenheim Museum in Bilbao, Spain, topping the list — the poll was met with extended grumbling. Some people griped about the many architects, including Richard Meier and Daniel Libeskind, who voted for their own work (Vanity Fair indeed!); others noted that the average age of those polled seemed to be around 70.

But the biggest complaint, by far, was that the results seemed completely to ignore green architecture, arguably the biggest single movement in the field since the emergence of modernism a century ago. In response, Lance Hosey, a writer and an architect who worked for years at William McDonough + Partners, a Virginia firm known for a commitment to sustainable design, organized an alternative survey for Architect magazine in which he polled a number of leading green architects and others. (Hosey e-mailed me earlier this month asking if I’d take part in the voting, which I did not.) He used the same format as Vanity Fair: He asked each voter to name the five most important green buildings since 1980, and separately the single most significant sustainable building finished since 2000.

The results were released Tuesday. The winner in the first category was the Lewis Center for Environmental Studies at Oberlin College, a building by McDonough + Partners that relies on solar panels, among other green-design features, to produce 30% more energy than it uses. (Hosey swears his old affiliation had no impact on the results, though the voters did include one current McDonough employee, Kira Gould. Unlike Vanity Fair, Architect has no plans to publish the contents of each ballot; Hosey did tell me, though, that one architect in the poll gave every one of his votes, six in all, to his own work.) Renzo Piano’s California Academy of Sciences in San Francisco, which is topped by an undulating green roof made of native plants, was named the most important sustainable building since 2000.

I don’t have any issues with the winners of Hosey’s alternative survey: I admire both the McDonough and the Piano buildings, and I can understand the desire to confront the obvious limitations of the Vanity Fair project. (Similarly, given the way the Vanity Fair poll was set up, the Guggenheim Bilbao struck me as entirely deserving.) In the end, though, I have the same basic problem with Hosey’s effort as I did with the first poll: Asking voters to nominate single buildings necessarily produces results that give a skewed view of the way architecture — and more important, the way we think and write about it — has evolved in recent years.

Among critics and architects alike, there has been a rising understanding that architecture is not just about stand-alone icons but is tied inextricably to urban planning, real-estate speculation, capital flows, ecology and various kinds of networks — and similarly that architecture criticism means more than simply writing about impressive new landmarks, green or not, produced by the world’s best-known firms.

Indeed, sustainable design and its champions deserve significant credit for helping architecture as a whole adjust its values and move toward a wider, richer sense of how to measure its progress and chart its signal achievements. In that sense, it seems to me that Hosey wound up falling into the same trap as the Vanity Fair tastemakers whose shortsightedness he hoped to correct.

Maybe, in other words, the most important achievement in green architecture over the last 10 or 30 years is not a single building at all. Maybe it’s a collection of schools or linked parks or the group of advisors brought together by a young mayor somewhere. Maybe it’s a new kind of solar panel, a tax credit or a zoning change. Maybe it’s tough to hang a plaque on — or photograph for a magazine spread.

Great Green Buildings of the World – ACROS Fukuoka

Twice in the last 24 hours I have come across this green building located in Japan in the news.  Yesterday for its award of being named having 1 of the top 5 green roofs in the world (I can’t recall where I read; so if interested check your search engines) and again moments ago on the Urban Igloos Blog.  It is very striking and I want to bring it to your attention.  Apparently this acclaimed project is not getting much exposure in the US, according to Urban Igloos, so let me do my part.

EDITT Tower – Singapore Goes Eco-Friendly

Every time I see this new genre of eco-friendly-green-buildings (like the EDITT Tower) I am inspired.  These buildings are inviting to look at and like I did as a young boy exploring Navy vesels in New York Harbor with my dad, I want to explore every floor, view and perspective.  Because these buildings have the potential to change the urban living experience for future generations, including rethinking the impact of sustainable design on our personal lives, I am showcasing them here.

Freshome Blog: What, you though only Dubai and China have the most stunning buildings in the world? Guess again, because EDITT Tower (“Ecological Design In The Tropics”) will be built in Singapore with the financial support of their National University and should be the most eco-friendly in the country. The most interesting thing is that this 26-storey building will use photovotaic panels and will be wrapped in organic local vegetation that will act as a living wall insulator. More to it, the skyscraper was designed to collect rain-water, both for plant irrigation and for its “needs”. If you want to congratulate someone, T.R.Hamzah & Yeang have had their hands on the project.

Big Dig House: Recycled Residence Reaches Completion

The Big Dig was a carbon footprint disaster, but it’s salvaged materials helped seed a few green sprouts.

If the walls of the Big Dig House could talk, they’d tell you that it’s comprised of 600,000 lbs of recycled materials that were rescued from the Big Dig highway project in Boston. Inhabitat last reported on the striking modern residence in 2006 when it was still in its planning stages, and it has since come a long way from being a pile of rubble and recycled materials. We may now behold what stands today — an elegant and modern private home in Lexington, MA with an exciting backstory.

At a final cost of $150 per square foot, most of the materials for the Big Dig house were free, minus the expenses to ship the materials to Lexington, MA. Set in an area of Lexington called Six Moon Hill, the finished Big Dig House has joined other modern homes that are well known to the area.

To save time and energy, Single Speed Design, engineers and designers of the Big Dig House, used most of the salvaged materials from the Big Dig in the condition in which they were found. Using the structural materials “as is” equipped the house to take on a much heavier load than standard building materials. As such, the house features an elaborate roof garden above the garage. Slabs of concrete reclaimed from the highway support three feet of soil, and the entire garden is designed to use recycled rainwater.

The house’s exterior is elegantly clad in cedar siding and glass, giving it a clean and modern finishing touch without disguising the exposed steel tubes and beams. They say that one man’s trash is another man’s treasure. The Big Dig House is a perfect example of the treasure to be found in recycling and reuse.
