The Pearl River Tower in the country's industrial hub is slated to become one of the world's most energy-efficient office buildings
GUANGHZHOU, CHINA — Special to The Globe and MailPublished on Friday, Nov. 27, 2009 12:00AM ESTLast updated on Monday, Nov. 30, 2009 3:16AM EST
In an artist's rendition, the Pearl River Tower soars above the Guangzhou skyline looking like a cross between a flattened rocket ship and a cellphone.
Still a half-completed, hulking concrete shell, the 71-storey building in China's southern industrial hub is billed to become one of the world's greenest office towers when it's finished late next year.
"We believe it will be the most energy-efficient tower in the world," said Roger Frechette, an engineer and the Chicago-based director of sustainable engineering with Skidmore Owings and Merrill LLP (SOM), the U.S. firm that designed the building and is overseeing its construction.
"Hopefully it will be the first of many built in the world. We really need them now," Mr. Frechette said in an interview during one of his many trips to Guangzhou. He calls the 2.2-million-square-foot tower "the project of a lifetime."
Though the total cost of the building has not been disclosed, it will use about $13-million (U.S.) in environmental technologies and adaptations, including wind turbines to supply its power, and heat-saving and cooling technologies to minimize the amount of electricity consumed. The tower's top 10 floors are to serve as the headquarters of the state-government-affiliated Guangdong Tobacco Co., with additional office space to be leased later.
The state affiliation has allowed the designers to test what they believe is a new frontier in sustainable construction, which they say at present may be possible only in China. While the recession has slowed building work in other booming centres such as Dubai (where SOM was the architect behind the spindle-like Burj Dubai skyscraper), massive government spending in China has kept the cranes operating.
Until recently, environmental concerns have taken a back seat to the incredible pace of development in China, where the government has resisted accepting targets to limit carbon emissions ahead of next month's UN climate summit in Copenhagen.
But there is increasing interest in the use of green technologies. Under law, China is required to produce 15 per cent of its energy from renewable sources by 2020. The 2006 law is driving the construction of massive wind farms, the world's biggest plant to convert sunlight to electricity, and an entire city - Ordos in Inner Mongolia - built on the concept of sustainable living.
In Beijing, developments such as the Modern MOMA office and residential complex include geothermal heating, wastewater recycling to feed its surrounding gardens, and a specialized indoor ventilation system.
But the Pearl River Tower is seen as one of China's most experimental buildings yet.
"When we first put the design together, we had a lot of people look at it, even in our own firm, who said, 'You're wasting your time. China's not really interested in sustainability,' " Mr. Frechette recalls
.
"A lot of people made that assumption and I think it's wrong. ... In the last few years, we've seen China get very aggressive on sustainability."
Initially, the tower was designed to be a "zero-energy" structure, meaning it would produce as much power as it consumed using a series of wind turbines. Though that design had to be modified to fit local regulations, the tower will still use half as much power as regular office buildings for heating and cooling, ventilation and lighting.
Two floors of the tower will have wind turbines built inside; the building is designed to funnel the prevailing winds in through openings in its walls to keep the turbines running.
Double windows and automated window shades will help regulate the temperature; rooms will be cooled using chilled water run through copper pipes, saving space over traditional air conditioning systems.
The architects also promise that the cutting-edge ventilation system will produce better indoor air quality, a key issue in China where air pollution and outbreaks of airborne viruses such as H1N1 and, in years past, SARS are major concerns.
Opinions are mixed as to whether the tower will live up to its billing. "China's green technology must fit with China-specific conditions," cautioned Qin Youguo, a professor in the School of Architecture at Beijing's prestigious Tsinghua University.
"Being green here means the technology helps people in harmony with nature in a low-energy and sustainable way," Prof. Qin said. "What works as green technology in another country may not be green in China if it doesn't fit the situation here."
While Prof. Qin criticized many of the efforts thus far as showpieces with little real impact, others in the industry say real progress is being made. Architects say Chinese developers' interest in green concepts such as water recycling and energy efficiency is growing, and that clients are also calling for such ideas in project proposals.
"Generally, I can feel more interest of Chinese developers on the green concepts, such as environmentally friendly, power-saving, water-saving, low-carbon-emission [designs], especially in the last couple of years," said Ma Weijun, assistant chief engineer at Shanghai-based East China Architectural Design and Research Institute Co. (ECADI), one of China's leading architectural firms. "Sometimes, it is the clients' requests but we also guide our clients in this way. I can feel the change through our clients," Mr. Ma said.

This is a great move, but I think it is totally possible to dramatically reduce pollution and energy use in China via cheaper means. Like city planned for public transportations instead of private cars, that and ESPECIALLY less suburbs.

In time globalwarming Rox1...China is changing, but it will not be overnight.

Talking about a cap on emissions is just that, talk.
Doing something like Pearl River Tower is doing something.

It will not be easy. With the TV ad, people will just spend. What do you think when a nice BMW Z3 drives by.
It will take another 10 to 20 years when People in China will do the same thing. They still have the moral "why those foreign can drive a nice car and not me?". Also, it is not fair for them not have a chance to have a nice car by themselves.
The only thing is sure. "we are lucky that we have the car early. We can drive before Global Warming is an issue"

It's taken the G&M a long, long time to discover this story. China has been making plans to green its economy for some years now. Go check out their deals with Singapore to create eco-cities. It's very ambitious. G&M should get that good-time boy McKinnon cover holiday resorts in Asia, and have someone serious to discover the big stories taking place in China.

Vehicles are small thing, oil only takes about 10% of Chinese energy consumption, the imported energy only meets about 5% of Chinese energy demand.
People need to realize the scale and scope of China...

phcheng:
the things is, comparatively, it's far easier for underdeveloped countries to make the green shift, since there are far less infrastructures to replace. Cities that are still growing could take this chance to build itself with the most innovative ideas. Build around the ideas of public transit and walking streets, instead of private cars.
Yes, we need private funds. But we ought not to be slave of capitalists now or are we? Modern China is still in the early development stage, if it could bypass the established development models, the Chinese could create something new altogether.
Look at the state of 401 and tell me what the Chinese should do with their highways when everyone starts driving their own cars.
"It will not be easy. With the TV ad, people will just spend. What do you think when a nice BMW Z3 drives by. "
What's the authoritarian government for then? I've seen it, the way local government heads beg the investors is simply degrading, just fncking degrading. Where's their pride? Where's their gut?
When a nice BMW Z3 drives by, people should be taught to think, what the fck is that thing doin here, it didnt even pass the chinese emission requirement.

Talk about Human Rights, we all born to be equal, and enjoy the same rights to pursue happiness. The only fair way to deal with the problem is very simple. Ask the leaders of all nations to come up with a per capita green house gas emission cap apply to the whole world. As the Chinese official point out yesterday, the Chinese would not accept that they are only deserved to live one third, one fourth, or even on fifth the living standard as the developed word people enjoy now.

China to announce intensity caps on GHG's at Copenhagen, inconvenient truth be told as Lomborg points out they will still double total emmsions by 2020....hurray! Announce then slink away, meanwhile Canada is villified by the left as do nothing, whatever!

Here's a copy of my message to the David Suzuki Foundation regarding Climate Science and Climategate:
With all due respect to your earnest organization,
Climategate:
a) data manipulation
b) subversion of the peer review process
c) intimidation of science journal editors
d) persecution of skeptics
e) revelations of a non-consensus internal to CRU models and data
f) communications through an unelected UN panel stacked and hand-picked by CRU members
g) millions of dollars of grant money at stake
h) destruction of data
i) obstruction of the freedom of information act
j) unprofessional conduct
I can not support the largest wealth transfer in human history based on a science so full of arrogance and pettiness. The probability of error in this group appear extreme as demonstrated by the collective conduct. Rationality has not been demonstrated.
Respectfully.

welcome to the real world, get use to it. next time, perhaps you could focus on the trillions of dollars already SPENT on weaponries. Your rational brain should tell you which is the worser to spend taxes on.

Not only does smog come out their air, it comes out of their mouths as hot air and b.s.! Human Rights Abusers and Mfg of mickey mouse and cheap quality products. Just got automotive blub made in china for GE from Canadian Tire in pack of 2 only one works turn signal, what crap they produce and we do not want this autoelectric car of theirs being sold in Canada. Do you get the message China. Your Crap Shoot!

John Q. Public...
The cost of becoming environmentally responsible (including reducing greenhouse gases) = paying more for consumer good you don't really need, driving smaller vehicles, being more energy efficient at home and at work, reducing your consumption of processed foods.
Cost of doing nothing = possibly condemning your children (and mine) to a world that is more desperate than the one we see today.
The cost of doing something is so far less then the cost of doing nothing. I am willing to take the word of science.
