Greening Guangzhou

Guangzhou, the third largest city in China, suffers from the worst air pollution in the country. Owing to coal-fired electricity plants, as well as the use of coal and heavy oil in manufacturing, the air pollution is estimated to be the equivalent of smoking 8-10 packs of cigarettes a day.

Acknowledging this situation as unsustainable, the local government, in conjunction with the national government and local business, have set out to improve not only the environmental conditions, but also the aesthetic conditions for the ten million who live in Guangzhou.

World Architecture News (WAN) reports:

"Heller Manus Architects has been awarded the contract to design Guangzhou’s Southern Axis... Heller Manus will now develop their plans for 14.78 sq km of the city incorporating waterfront and transit oriented development with a ferry terminal, central government districts, and a variety of urban land uses."

Heller Manus is based in San Francisco, and promotes designs that suitably blend function with the local culture. WAN notes, "The Heller Manus concept was chosen for its balance of growth with sustainability and preservation, while promoting amenities for better livability."

Green roofs appear to be a significant element of the design, in addition to larger green spaces. In the context of improving Guangzhou, green roofs will help reduce the choking, fine particulate matter air pollution, as well improving storm water runoff. Both clean air and clean water are challenging not just for Guangzhou, but for China as a whole.

Grow indoors

Green roofs will also improve quality of life issues for the residents. Green roofs will provide green space for residents to escape the crowded city life and enjoy the view. Other possibilities include urban agriculture to improve food security.

As China continues to grow, its population is becoming more aware of the environmental consequences of rapid industrialization. Projects such as the modernization of Guangzhou, and dream cities such as Dongtan, will help prevent catastrophic and irreversible environmental damage and improve the overall health of its citizens.

Germany's ECO CITY

Germany, already a leader in green roofs, is now working on its own ECO CITY. Full of green roofs, wind turbines, and other sustainable technologies, ECO CITY hopes to revive the historic Hamburg-Harburg Harbor.

Total Gym® Home Fitness Equipment - Over 1 Million Satisfied Customers. Get the Body You've Always Wanted!

Hamburg-Harburg Harbor, situated on the North Sea, has been a hub of trade and industrial activity since the 19th century. Although the original factories have since left, the historic area still has many classic buildings that ECO CITY wishes to retain and reuse in the renovated and sustainable city.

Site reclamation and renovations are difficult enough, however, ECO CITY takes this project to the next level. Inhabitat.com and World Architecture News both report one of ECO CITY's goals is to achieve certification from the three leading "green" building bodies (from WAN):

"...USGBC’s Leadership in Energy and Environmental Design (LEED) Program, the Building Research Establishment Environmental Assessment Method (BREEAM), and the German Sustainable Building Council (DGNB)’s Program. Currently, ECO CITY is seeking the highest level of environmental certification from all three programs."

To achieve top marks from each of these bodies, buildings must produce renewable energy, be built with recycled materials, and use the renewable energy to sustain the project, e.g., solar lights, passive cooling, etc.

Green roofs are a key element of the project, not only to reduce storm water runoff, but also to improve the quality of life of the workers in the area. ARUP, the designers of Dongtan, the green city in China, is one of the key developers of ECO CITY. Their experience with green building, and Dongtan in particular, will help make ECO CITY a success.

Ireland's Green Roofs Videos

Ireland is one of the world's greenest countries, at least in terms of flora and fauna. However, Ireland is also the home of ancient and modern green roofs.

Long before China, Chicago, or New York put green roofs on buildings, the Irish had done it in Newgrange. Newgrange, is home of a megalithic burial site, a mound that covers about an acre, covered with a green roof. The site was thought to be built around 32oo BC, and is typical of other mound sites throughout the world, all of which have green roofs. Free Shipping on any purchase over $25

What has Newgrange to do with modern green roofs in Ireland? Everything! Historically, Ireland's agrarian culture and temperate climate has created in its populace a love of the land and local environment. It should come as no surprise then, that "...Miles Sampson, a County Clare-based architect specializing in sustainable homes," has created a very green home in Ireland, with a series of green roofs. Click here for the lowest available Air France fares.

According to Matt Hickman at Mother Nature Network,

"The building of one of his low-energy homes, a “Geomorphological House,” in the rural west of Ireland has been captured on film and even if you aren’t intrigued by the home’s various green features (grass sod roof, vacuum tube solar panels, recycled newspaper insulation, heat recovery ventilation system, etc.)."

To highlight his design, videos were made describing their features and construction. They are quite enjoyable! Please enjoy the videos of this great house with green roofs in Ireland!

Colombia Joins the Green Roof Movement

When many people think of green roofs, they generally think of cities such as Chicago, Washington, DC and Shanghai. While these cities definitely need the benefits of green roofs, non-polluted environments can benefit also. Take Colombia, with its varied geography and mild climate, is a great location for green roofs.

A recent project, designed by G Ateliers, in Guatapé, Antioquia, Colombia sports green roofs on structures that blend into the surrounding environment. FREE SHIPPING on orders over $50.00 at InhabitLiving.com

The structures, known as "Ecological Shelters," are about 2 hours from Medellin and were built for potential use in eco-tourism. The idyllic country-side, with rolling hills, and a large lake nearby creates a perfect setting for "getting away from it all."

What is also nice about these "shelters," is that the green roofs were designed to be used daily, and not just for their benefits, such as reduced HVAC costs, storm water runoff management, and air pollution reduction.

Masdar, the Green City for Abu Dhabi

While I have written about green cities in the past, Dongtan, in particular, the only city that has started construction is Masdar, in Abu Dhabi.

Designed for 40-50,000 residents and another 50,000 commuters, Masdar will utilize solar as its primary electricity source. The first 10 MW power station went online in January 2009, according to UAE Interact.

Additional green features include grey-water recycling systems, an highly-efficient desalination plant, as well as "... the world’s largest solar thermal driven cooling and dehumidification system. " In addition to green systems for electricity and water, the building materials themselves had to be green. The steel had to be recycled steel, as well as the aluminum.

Another interesting highlight of the city, besides having no cars and the use of "personalized rapid transport pods," is the planned use of sequestered CO2 to improve the efficiency of oil drilling.

Although green roofs don't appear in the plan, the volume of flat roofs is significant. The need for electric power determined the use of the flat roofs, instead of green roofs. Additionally, green roofs in the desert aren't efficient, as they required significant water resources. Indoor gardens.

The city was designed by Foster and Partners of London.

A Green Roof in Cape Town

While green roofs have really taken off in Chicago, China, Germany, and San Francisco, they haven't seen as much growth in Africa, until now.

SouthAfrica.info reports:

The Cape Town International Convention Centre and the South African government are at an advanced stage of negotiations on a partnership to expand the hugely successful conference and expo venue, and in the process to create "the greenest building in South Africa".

Although South African continues to struggle with crime and economic issues, they are have taken a big step in improving the "greeness" of their buildings, but public and private.

In this particular project, "... would be built to requirements set by the Green Building Council of South Africa. It would be designed to use 40% less energy per square metre than the present CTICC, consume 95% less potable water, and produce 25% less waste to landfill."

What would any post on blog be without a green roof comment? The CTICC will have a green roof! The South African climate in general, and Cape Town in specific, is an excellent environment for a green roof. The cooling effect and storm water management capabilities add tremendous value to this building.

Not only does this project bring positive environmental value to buildings and area, it also brings jobs and revenue. "...the project would result in direct spending in Cape Town of R2.27-billion over an anticipated three years of construction," and "...513 "direct jobs" and 720 "indirect jobs" would be created in 2012, increasing to 1 276 direct jobs and 1 892 indirect jobs by 2018."

As more green roof projects become reported in Africa, I will report them here. Best wishes to Cape Town and their CTICC project!

Green Roof in Lima, Peru

In my previous posts, I have discussed green roofs from all parts of the world, though there has been a strong emphasis on China. Part of this emphasis has been that China is in desperate need of cleaner air, and there appears to be a desire to build more sustainable buildings. $20 Off AeroGardens

However, there are wonderful examples of green roofs throughout the world. This post's example comes from Lima, Peru. According to LivingRoofsinc.com, the picture at the top left is of the LarcoMar commercial center. What looks like just a city park is actually an extensive green roof. LarcoMar is a very popular tourist destination built into the cliffs that bound the Pacific Ocean. It is also home to very high-end retail. Organic Flowers & Gourmet Gifts

So, if you are Lima and looking for that new Versace bag, stop by and see the beauty of this great green roof!

Another Green City for China

In the 9/25/2008 issue of "China Daily," there is an article titled "China Singapore Team Up on Green City Project."

China, in cooperation with Singapore, is looking to build a new, green city on a piece of land that would otherwise be unsuitable for habitation.

From the article: "The eco city is located in Tianjin's Binhai New Area. It will cover a total of 30 sq km - 20 sq km in Hangu district and 10 sq km in Tanggu district. It is 15 km from the central part of the Binhai New Area, 45 km from downtown Tianjin, and 150 km from Beijing."

The planners are estimating a population of approximately 350,000 when complete in 10-15 years. Additionally, it will have five commercial centers.

From a sustainability point of view, "Clean energy and renewable energy resources - such as wind power, solar energy, underground heat pump and air source heat pump - will reduce carbon emissions in the city. All the buildings in the eco city will have to conform to green architectural design standards." Green roofs are included in the design.

This is the latest in a green building boom in China. Shanghai working on a green roof program, Dongtan is the green city in southern China, and Songjiang, the new green resort being built. In each of these cases, green roofs play a key role in reducing air pollution, the urban heat island effect, storm water runoff, as well as improved energy efficiency.

Interview with Atkins, Part II

This is the second part of the my interview with Atkins regarding the Songjiang resort complex, in Songjiang, China, near Shanghai. Read Part I here, and the original post ("China's Green Resort) here. Many thanks to Atkins for their time and cooperation with this interview.

Assuming the overall project is successful, does Atkins expect other Chinese hotels to use green roofs or event to remodel existing structures to promote cleaner air?
This depends on the context and location. Green roofs have their use and place but not in all situations. However it is our intention to promote green issues in hotel design in appropriate forms in all our projects.

What are the risks to this project? Specifically, are the current global credit situation or the cost of oil creating stress on the project?
Risks are that the budgets may be reduced and thus reduce the sustainability elements in this particular project. However certain features such as the green roof are an integral part of the design and cannot be omitted.

Outside of the Shimao, who are the key stakeholders in the project?
Shimao are the developers. They are currently negotiating with the prospective hotel operators. At the moment, the operator’s identity is confidential.

Has this project inspired inquiries by other hoteliers to create their own Songjiang-type hotels?
Yes we have had inquiries from a number of developers/operators in China as a result of this success. Some have specifically requested for sustainable content within their concepts.

Interview with Atkins, Songjiang's Architect

This article is the first of a two-part interview with Atkins, the architects of the Songjiang resort complex.

Many thanks to Atkins for their time and thoroughness in answering the following questions.

What were the motivations of Shimao to build Songjiang? In particular, why would they choose such a unique design?
The site is within a larger context of the ‘Shimao Wonderland’ development – a themed leisure/tourist destination. The challenge was to successfully develop such a difficult ‘brownfield’ site within this scheme.

What were the key differentiators between Atkins and its main competitors that ultimately led the Shimao to choose Atkins for the Songjiang project?
Our solution successfully integrated ‘green’ elements with the concept. The combination of the ‘green roof’, the’ hanging gardens’ and the underwater aquarium elements clearly expressed the client’s plan for the development. There is an ‘organic’ quality to the design which enables it to fit into the environment so effortlessly.

My readers are very interested in green roofs. What was the motivation to use such a large green roof?
It was the best way to integrate the building into such sensitive environment. The area is known for exceptional landscape and several green hills. This building was conceived as another ‘green hill’, and is meant to be a natural addition to the local landscape. Moreover, the environmental benefits in terms of biodiversity and the benefits to the building through the acoustic and thermal insulation lead to its utilisation.

In modern history, China has seen the natural environment as both a hindrance and a great resource. Is China trying to have both growth and environmental sensitivity with this project?
Yes, this project is intended to express the traditional and respectful attitude of the Chinese to nature. In all our architectural projects around the world we are specifically drawing attention to the importance of sustainability in building and harmony with natural environment.

China's Green Resort

China is one of the fastest growing economies in the world and suffers the effects of that rapid growth. Air pollution and storm water runoff effect their major and minor cities.

The Chinese government has acknowledged these problems and has taken steps to improve the situation. One way is through green roofs.

Shanghai has defined targets for the number green roofs (details here) and design firms are lining up for cities' worth of opportunity.



Outside of Shanghai, in the Songjiang district, Atkins has designed the "Songjiang Garden City," with a resort as the focal point. According the Greenroofs.com:

The innovative design of the 400-bed resort hotel stands two levels higher than the rock face of the 100 metre deep quarry and includes underwater public areas and guestrooms... Sustainability is integral to the design ranging from using green roofing for the structures above the ground level to geothermal energy extraction.



As this is part of a larger project, as mentioned above, I will be conducting an interview with Atkins Design to learn more. Until I publish the interview, Greenroofs.com and Atkins both have good articles about this project.

A New Green City for China, Interview Part II

As I have written in the three previous articles (here, here, and here), Dongtan is going to be "...a city powered by local, renewable energy, with super-efficient buildings clustered in dense, walkable neighborhoods; a recycling scheme that re-purposes 90 percent of all waste; a network of high tech organic farms; and a ban on any vehicle that emits CO₂."
To get more information about the project, I have conducted an interview with Arup, the city designer. This is the second of two articles with details from the interview.

So, how does this type of dream city actually get built? The simple answer is money. HSBC and Sustainable Development Capital LLP (SDCL) are going to provide the majority of financing for the development. Both of these companies are natural contributors for this project.

From the HSBC website, "The HSBC Group is named after its founding member, The Hongkong and Shanghai Banking Corporation Limited, which was established in 1865 to finance the growing trade between China and Europe." SDCL, from its site, "SDCL has an exclusive focus on projects which it considers: Have a positive environmental and social impact; Can create attractive levels of return on investment (commercial sustainability); and Are potentially transformational."

Continuing with the theme of balance between sustainability and Chinese design, it also helps to consider the philosophy of Mao Tse-tung, which considered nature an obstacle, and that of Hu Jin Tao, which declared the necessity for ecological balance and sustainability. In both cases, Dongtan will be the area to find that balance, both to sustain a growing population, as well as maintaining the highest ecological standards possible.

The final question I asked was whether Arup was persuing other similar projects? They highlighted two projects, Wanzhuang, in China and Treasure Island Community Development (TICD) in San Francisco. In both cases, sustainability, renewable energy, and ecological protection are the main drivers in the development.

I congratulate all of the parties involved in the Dongtan project and give my best wishes for their success. Further, I would like to thank Arup and its Press Office for being so generous with their time. As the project progresses, it is my intent to provide updates. Additionally, I will do the same for Wanzhuang and Treasure Island.

A New Green City for China, Interview Part I

As I have written in two previous articles (here and here), Dongtan is going to be "...a city powered by local, renewable energy, with super-efficient buildings clustered in dense, walkable neighborhoods; a recycling scheme that re-purposes 90 percent of all waste; a network of high tech organic farms; and a ban on any vehicle that emits CO₂."
To get more information about the project, I have conducted an interview with Arup, the city designer. This is the first of two articles with details from the interview.

As previously mentioned, the development is being led by the Shanghai Industrial Investment Corporation (SIIC). My first question was why China wants to build a "green" city, with all of the sustainable elements. The answer can be found in a speech by Chinese President Hu Jintao, at the 17th National Congress. While I am not fond of communist propaganda, he does mention several times the need to improve environmental conditions and reduce pollution.

The second question was why Arup was chosen. While the SIIC didn't comment specifically, Arup has over 30 years experience working in China and also uses a system called Integrated Resource Management (IRM), which is a tool to optimize land use. This tool accounts for water, waste, energy, and living space necessary on a given piece of land. In this case, Dongtan is projected to hold 500,000 people at capacity.

One item that will make this city unique is that Arup has provided a design specification for types of buildings. The specifications allow designers, architects, and developers to provide structures that reflect the Chinese character of Dongtan, while creating a sustainable, green living space. Many of these buildings will also have green roofs! Green roofs reduce utility costs, storm water runoff, as well as CO2 and air pollution. Green roofs also can provide aesthetic benefits for those living in and around the buildings. Since no building will be much over eight stories, these roofs should be visible from street level.

The next article will cover questions regarding financing partners, the potential for similar projects, as well as the public response. Many thanks to Arup for participating in the interview process.

A New Green City for China, Dongtan Videos

Below, you will find a three videos about Dongtan, the city in the previous post, "A New Green City for China." Don't forget to also read the interview articles either (Part I, Part II)!

The first video is part one of Alejandro Gutierrez, Program Designer at Arup, talking about Dongtan. The second video is the second half. They are a little hard to hear, but worth the effort.

The third video is a fly-over video, providing an artists impression of what the city will look like.

Please note that I am working on a series of interviews with Arup to further explain the project.

A New Green City for China

**Be sure to read the update with Interview 1, Interview 2, and videos. **
Shanghai has a growing population, heavily polluted air, dirty water, and power shortages. But just a short ferry ride away is a wild-life preserve that will soon become its first green city.

Dongtan, which according to Business Week, "About the size of Manhattan, Dongtan aims to be energy self-sufficient using a combination of wind, solar power, and biofuels." The design is being done by Arup Group, out of London, with Alejandro Gutierrez as the Project Designer. Peter Head is the Project Director, and Roger Wood is the Project Manager. The final customer is Shanghai Industrial Investment Corporation (SIIC), and they will be making the final decisions. Cheap? No. 100% Free. Trade stocks for free on Zecco.com.

According to Gutierrez, as quoted in Wired Magazine, Dongtan will be "...a city powered by local, renewable energy, with super-efficient buildings clustered in dense, walkable neighborhoods; a recycling scheme that re-purposes 90 percent of all waste; a network of high tech organic farms; and a ban on any vehicle that emits CO₂." Of course, many of these buildings will have green roofs! Water Barrels and Storage

Because this is such an interesting topic, Arup has agreed to be interviewed about the Dongtan project. My goal is to bring you the details of this emerging and fascinating story! Green roofs are going to be a part of this major endeavor, and I predict it will only help their popularity.

Bejiing Worst Smog in a Month - Green Roofs Can Help!

In an article in July 28th, This is London, about air pollution in China, states that despite its best efforts, "The grayish haze was one of the worst seen in Beijing in the past month despite tough traffic restrictions imposed a week ago to help reduce pollution."

Green roofs are known to reduce not only CO2, but also fine particulate matter air pollution. These benefits are especially important given the amount of power generated by coal, lax (by Western standards) industrial emissions standards, as well as the lack of pollution controls on vehicles.

To China's credit they have done the following:

"...include pulling half of Beijing's 3.3 million vehicles off the roads, closing factories in the city and in a half dozen surrounding provinces, and halting most construction in the capital. Some 300,000 heavily polluting vehicles, such as aging industrial trucks, have been banned since July 1."

Let's hope that the conditions improve so that the 2008 Beijing Olympics can be a successful display of peaceful competition.

Green Roofs in China, Helping Beijing Breathe

The greatest inspiration for me to blog about green roofs was my trip to Shanghai, China in January of 2008. There I saw incredible air pollution, which literally was choking.

While I sat in several different office buildings, many stories into the skyline, I observed huge swaths of flat roofs, mostly black, sitting idle. Additionally, I remembered the discussion about how energy starved Shanghai is, as well as concerns about water.

As one of my meetings ran long, and somewhat boring, I began to map out a strategy of how Shanghai could adopt flat green roofs, reduce air pollution, and minimize storm water runoff. I admit, the plan was grandiose, so that's why I settled on a blog instead.

It turns out that in 2006, several stories ran about green roofs in Beijing, where, according to the US embassy, has worse air pollution than Shanghai. Here are some quotes from articles at that time. There is also a nice mention of LEED in there.

"The Beijing Linked Hybrid project, a self-contained city of linked vertical buildings designed by Holl, includes hundreds of apartments as well as stores and schools, and every roof is green. Storm water collected in rooftops will help feed a self-sustaining water system to protect the buildings against water shortages in Beijing, Holl explained.

"They want it and they're willing to pay for it," Holl said of his Chinese clients.

China launched a nationwide drive last month to make energy-saving buildings that help ease fuel shortages and reduce greenhouse gases. The country has also signed an agreement with the United Nations to promote environmentally friendly practices in staging the 2008 Beijing Olympics." from "Landscape architects tend to a green roof" found at http://www.msnbc.msn.com/id/12512892/.

From the Christian Science Monitor:

""There isn't much pressure for us to promote the green concept," said science ministry official Yang Guoxiong at last week's green inauguration.

"The national government has incredible intentions for a green future." says Mr. Mars. "Really mind-boggling. But we are in an interesting paradox, and I am asking, 'Is it better to have high ambitions, or to be realistic?' " http://www.csmonitor.com/2006/0403/p07s02-woap.html

Let's hope the rest of China can catch the green roof wave and bring clean air to their cities and citizens.

Green Roofs in the UK

sedumsupply.co.uk

Green Roofs aren't just an interesting topic in the US, they are also found in Europe. Livingroofs.org is an organization based in the UK that is leading the charge in promoting green roofs. Their site makes an excellent point:

"In the UK, the increased pressures on urban land and increased density levels are likely to have adverse impacts on drainage, water abstraction, biodiversity, accessible green space, and local climate conditions."

This statement is strongly applicable to cities such as Beijing, Mexico City, and others that suffer from choking air pollution and difficulty managing storm-water runoff. Storm water runoff is a major pollutant to drinking water sources. Green roofs can capture that rain and filter it through the soil instead of dumping it into reservoirs and over-taxed water treatment plants.
