Green roof tops Daum Communications / Ilshin Building, Seoul, Korea

Seoul is not known for it eco-friendly building designs, but a couple of buildings I encountered recently, which have significant green roofs, have made me thinks that there may be hope yet for this city.

A Green roof according the Wikipedia:

A green roof is a roof of a building that is partially or completely covered with vegetation and soil, or a growing medium, planted over a waterproofing membrane. This does not refer to roofs which are merely colored green, as with green roof shingles.

The most significant benefit of green roofs are:

• Reduces cooling cost in the summer
• Reduces the city’s average temperature
• Reduces stormwater run off

The best known green roofs are Chicago City Hall, The GAP Headquarters and Ford Motor Company’s River Rouge Plant.

Yesterday I visited the new offices of Daum Communications, the distant-second-but-nicer-place-to-work Korean portal site (#1 is Naver.com). It is housed in the newly completed Ilshin building in Hannam-dong which is also the home to the Italian embassy. On the roof of the building I was surprised to discover a green roof. The chairman/CEO of Ilshin Spinning, Kim Young Ho, the building’s owner, is no stranger to design and architecture, having graduated with an architecture degree from Pratt in NY, and served on the board of the Korean Institute of Architects and also know for his formidable modern art collection. The anecdote recounted by one of the Daum staff was that he delayed the opening of the staff cafeteria on the 2nd floor of the this building because he was not happy with the design of trays.

A couple of weeks ago, I found myself at Ewha Womans University (Note: “Womans” is not a misspelling), one of the oldest and most prestigious universities in Korea. I was very impressed by their recently completed the Ewha Campus Complex, which was designed by French architect, Dominique Perrault. The building itself unnoticeable at first glance since it is half buried in the ground, but this makes for an impressive green roof.

Ground was recently broken for Dongdaemun Design Plaza, which replaces the aging Dongdaemoon Sports Complex. The London-based architect Zaha Hadid was awarded the commission following an international competition. The most prominent feature of the design is its fluid surface green roof that weaves and connects the various part of the design.

Digging through some old photos, I found this set I took in 1994, of Mapo area, in Seoul. This area had been home to many informal settlers (so called "moon village" or ???) but had been "condemned" to be redeveloped and replaced by more of Seoul’s ubiquitous apartment blocks.

David Kilburn, in a comment to one of my previous post Hanoi: Think different wrote about Seoul:

… A Korean architect I know describes modern Seoul as a city designed to drive people insane. This is a far cry from Korea’s own architectural traditons where it was always important that buildings were designed to nestle harmoniously into the landscape, neither dominating nor destroying it. The geomantic ideas that are better known as the Chinese “Feng Shui” were always important. Nowadays, the landscape is eradicated to pave the way for squadrons of identikit apartment blocks? Who benefits, certainly not the residents. The real beneficiaries are the owners of constructio companies, real estate speculators, and the corrupt politicians and bureaucrats who play their own role in detroying quality of life.

David has a very interesting documentary The Destruction of Kahoi Dong about the destruction of Han-ok’s (traditional Korean houses) in Seoul.

The last time I visited Hong Kong was in 1989.

Some things have indeed changed. For one thing, it’s part of China now. Also the skyline has many new additions, including the 88-floor (415m) 2 International Finance Centre tower, which is apparently the world’s 8th tallest building and tallest in Hong Kong. This will be soon surpassed by the International Commerce Centre being constructed across on the Kowloon side which will stand at 118-floors (484m).

Hong Kong also has a shiny new Norman Foster designed airport. Clean and efficient and the landing is not as super-hairy as the old Kai Tak airport. At the old airport you passed through mountains, cleared slums and then after a steep bank landed on a strip that seemed to go out into the water. As much as this is thrilling to some, I would prefer something a lot less eventful.

Many things haven’t changed. Hong Kong still maintains itself as one of the financial capitals, a shopping haven, one of the world’s most important shipping ports and trading gateway to China. And trams still run through its streets as do ad-covered double-decker buses.

I did the usual touristy things. I wandered through the infinitely looped and connected shopping malls and made the trip up to the Peak via the Peak Tram. Another new thing, there they built the Peak Lookout and charged HK$20 to take the escalators to the top for the view down to the skyscrapered financial district. What a rip-off! But I had to commend the thorough capitalistic mindset of extracting (extorting) money even for the view.

Even as a tourist, I was very impressed at how efficient a city Hong Kong is: The 24-minute train ride from the new airport to the center of the city. Buildings connected via covered walkways so that you don’t get wet and remain chilled. Public transport is cheap and fast. HK$5 (=US$0.65) for a 4-stop trip on the MTR from my hotel in Causeway Bay to Central. And apparently this efficiency is the reason people choose to do business here, reflected in the minimal red tape. When I asked my brother, who works for HSBC, where Hong Kong citizens’ loyalty lies, it is indeed money over state. Many Hong Kong businessmen fled to Canada, Australia, UK and other countries before the handover in 1997 only to return after they secured their citizenships.

Hong Kong is by far one of the most cosmopolitan places I have been to. They don’t care where you come from, just as long as you have the money or you are willing to do business. Given how global Hong Kong is, it’s still amusing to see that taxi drivers and clerks at 7-Eleven don’t speak English and didn’t have a clue as to what I was talking about. And Statue Square in front of HSBC which is the heart of Hong Kong still gets inundated with Filipino maids on Sundays, which is their only day off.

The weather was awful most of the two short days I was there, so I hung out a lot indoors. I ended up buying 2 books: Outliers by Malcolm Gladwell and Creating a World Without Poverty: Social Business and the Future of Capitalism” by Muhammad Yunus, founder of the Grameen Bank, father of microfinance and Nobel Peace Prize Laureate in 2006.

It’s hard to believe that it has been 20 years since I visited Hong Kong, which was half a lifetime ago. now that I have reached about the halfway mark of my life, I think it’s about time I figure out how to spend the rest of my life. I now realize the irony in my second book selection, given that I am was in one of the most capitalistic cities in the world. But it seemed appropriate that this is at the core of a decision that lately I have been thinking very hard about: whether to pursue capital gains or social gains.

According to people like Muhammad Yunus and Bill Drayton the world is changing. There is emerging a new type of business: Social business or social entrepreneurship. You know it’s gathering steam with you can see it appearing as MBA tracks in major business schools such as Oxford, Duke and Stanford just to name a few.

According to Yunus, Social Business is defined as:

Social business is a company that is cause-driven rather than profit-driven, with th potential to act as a change agent for the world.

Bill Drayton elaborates in an interview in 2007 that:

In the last two and a half decades we have seen all across the world, the structure of the social half of the world become as entrepreneurial and competitive as business.

They both forecast that we will see radical change in the way business will be conducted in the future, especially given the backlash against the greed of the past decades and the present danger to the world not being nuclear annihilation as it was in the 60′s and 70′s but the destruction of our life-giving environment and the fragile state of the world’s economy.

The current economic crisis is indeed a harsh wake-up call that there needs to be a fundamental change in attitude and values and not only in way we conduct business. If we can put our minds so singularly to solving business issues and the generation of wealth, it can also be applied to solving the crisis in environmental and social justice we are facing.

It’s strange how physical trips often lead us on thought trips.

A half-day walk through Hanoi

Hanoi is a walkable city.

You would never know this with all the traffic overflowing in the streets. Of course the locals will prefer to ride their scooters. It’s actually dangerous to cross the streets when you are overwhelmed by bicycle motorcycle, automobiles and bus traffic coming from all directions, with traffic signals and traffic lines ignored most of the time.

But the scale, the tree-lined streets, and the distance between landmarks do lend itself to a leisurely stroll. Deep down inside you know Hanoi is in fact a very walkable city, it just forgotten it for a while. Recovering this aspect will be something that will be key to making more tourist friendly and a more of an attractive destination.

Here’s one of my favorite walks, if you have a half day to spare:

1. Opera. Start preferably after lunch at the Highlands Cafe next to the Opera. Nothing like a good coffee to start the tour. My personal favorite from their menu is Mango Mania. The Opera was built at the turn of the 20th century by the French colonists modeled on Garnier’s Opera in Paris. Crossing the road is a real challenge for the first time visitor. Just remember to walk slowly and predictably (whatever you do, do not run) so that the traffic can be aware of your presence in the street. Once you cross the road, walk down Trang Tien street towards the Hoan Kiem lake. This historic street has many bookstores that have good materials in English and maps of Hanoi and Vietnam.

2. Hoan Kiem Lake. The undisputed spiritual heart of Hanoi. The name means the The Lake of the Returned Sword and legend has it that emperor Le Loi was handed a magic sword by a tortoise here that brought him victory against the Chinese Ming Dynasty. The walk around its periphery is one the more calm experiences in Hanoi if you can mentally block out the noise. Once you make the a 3/4 circle, cut back up Hang Trong and then down Nha Tho to face the cathedral.

3. St. Joseph’s Cathedral. A scale-down replica of the Notre Dame in Paris completed in 1886. The streets around the cathedral have attractive boutiques, souvenir shops, restaurants and cafes and is one of the more gentrified, tourist friendly parts of town. If you already feeling tired, drop by the Moca Cafe. For those seeking exotic home furnishings, Mosaique Boutique provides interesting buys. When you are ready to move on, take the alley to the right of the cathedral and make you way down Phu Doan towards Hoa Lo Prison/Hanoi Towers.

4. Hoa Lo Prison. AKA The Hanoi Hilton during the Vietnam War (or the American War as the call in here) incarcerated downed fighter and bomber pilots and crew. It was famous for being the POW home of Senator John McCain, and Pete Peterson who later became the first US ambassador to Vietnam since the US resumed diplomatic ties with Vietnam in 1997.

5. Hanoi Towers. A large part of the Hoa Lo Prison was demolished to make way for the Hanoi Towers. At 25 stories, it was the tallest building in Hanoi when it was completed in the late 90′s. You can stop the tour here, and finish at another Highlands Cafe for some refreshments. You can also go to the 4th Floor of the residential tower to a restaurant called “Jaspa’s” and order their famous Bun Cha.

6. Quan An Ngon. What’s a walking tour without a dining destination to motivate you. This one is well worth the walk. Housed in a spacious French-style Villa, which I was told used to be owned by a wealthy Vietnamese doctor, now is the venue for a very reasonably priced restaurant that serves glorified “street food”. A favorite for both Vietnamese and visitors alike, you should try to go beyond the familiar spring rolls. It will be a rewarding experience.

Old Town, Hoi An, Vietnam

I took a weekend trip to central Vietnam a few weeks ago. We arrived in Da Nang and took a taxi south to Hoi An. Hoi An seems to be known for 2 things: beach resorts and its Old Town designated a UNESCO World Heritage site in 1999. Maybe I was tired after spending the previous 2 weeks charretting on the project I am currently working on, but I was a bit disappointed by what I saw. The architecture was nice, but it seems like one big souvenir shop. Every building was selling some kind of “cultural artifact”. Is this what happens when a place gets designated a Heritage site?

Talking this weekend to Michael Waibel, a prominent socio-geographer who has been working in Vietnam for over 10 years, he told me that before it had the designation, it was just another disintegrating town, and at least now the locals have an income and finances to restore and revitalize the area. However I begin to wonder what is it we are preserving? What is the point of preservation?

This is what UNESCO has to say about the matter in its Historic Districts for All: a Social and Human Approach for Sustainable Revitalization, a manual for revitalizing historic districts:

Cultural urban heritage related the history of the city, its inhabitants, religions and social and cultural transformations. This heritage is deeply anchored in the spatial and economic structure of the cities, their buildings and monuments. The people living and working in the city identify with it. Today, historic districts are symbols of the city’s image; above and beyond their own cultural value they fulfill an important mission in modern urban development: they create the identity and the city’s image and are key geographic factors for the local and regional economy.

So the “why” in historic district preservation and revitalization seems to be rooted in a sense of identity for the local inhabitants. But the over-commercialization and the sales of mass-produced cultural artifacts you can now find homogeneously across Vietnam seems to go counter to that sense of local identity. Local crafts traditions are lost in place of what tourist will want buy. Is there a way to balance local identity with its economic sustainability? I had more questions than answers, and felt a little robbed.

Next day was My Son My son is Hindu temple complex constructed by the Champa civilization between 7th and 14th centuries, then abandoned and lost for centuries and only rediscovered by the French army in the late 19th century.

My Son is also a UNESCO Heritage site, but in stark contrast to Hoi An, My Son was relatively deeserted. The guide told me that in peak season, they get as many as a thousand visitor a day. That doesn’t seem a lot. In a well-rehearsed guide talk, he showed us on a map all the regions destroyed by US bombing during the Vietnam War. Apparently about 80% of the existing complex were lost during the carpet bombing raids.

On the way to Hu?, we stopped by the Marble Mountain in Da Nang. Don’t believe the guide when he tells you there’s only a hundred some steps to the summit. After we reached what perceived to be the top with nice temples, but he lead us rock climbing through naturally formed caves to the actual top. Ok for me but not ok for my boss who is fit for his age but close to 70. Nice view at the summit, but not worth the extreme physical effort for the benefit of our sadistic guide. What was more impressive was the huge natural caves that were used as a Viet Cong as a hospital until it was bombed. But it’s hard to know what to believe without the facts.

There are 2 way to get to Hu? from Da Nang. Through or boring tunnel or over the scenic Hai Van Pass. Our driver asked us what we wanted to do. Not having researched this fact, we elected thankfully for the Pass. Only tourists and joyriders seem to take the pass – everyone else takes the tunnel. Joyriders here are usually kids on motorcycles. We witnessed one accident where 2 kids on a motorcycles took a turn too fast and skidded out of control. Bike was damaged but the riders seemed ok.

Citadel, Hu?, Vietnam

Hu? was the imperial capital of Vietnam during the Nguy?n Dynasty between 1802 and 1945.

It wasn’t intended that way, but we ended up doing all three UNESCO Heritage site in Central Vietnam, the Citadel in Hu? being the last one. The Citadel is a sizable complex apparently modeled in part after the Forbidden City in Beijing, but only a scaled-down version, a fraction of its size.

We took a trip down the Perfume River to visit a few of the Imperial tombs. The most interesting of which was the tomb of the short-lived Emperor Kh?i ??nh (1885-1925). His was built of cement that had weathered pretty badly, now almost dark grey or black in some places. He was a francophile and the interior was constructed from a mosaic of broken French ceramics, and took 17 years to construct. Sadly for him, it was not completed before his death.

At this point, I was so exhausted that I stopped registering any new information and just mechanically took photographs. Still some came out pretty nicely. Check out the rest of the Da Nang, Hoi An, Hue Flickr photos set.

Panorama view from 25th floor of Hanoi Towers *

Hanoi Panorama

The view from the penthouse suite balcony of the Somerset Grand Hanoi, a.k.a Hanoi Towers is pretty amazing.

We’ve been looking for more economic alternatives for accommodations in Hanoi since we’ll visiting and working in Hanoi on a regular basis for the next year and a half, when we came across this one. It didn’t hurt to just look. It’s located on the 25th floor of the Hanoi Towers and has its own balcony overlooking downtown Hanoi.

The apartment was nice, but what was more surprising was the view: how few high-rises block your view. You would never get a view like this in Seoul, or any other major East Asian city. Hanoi is comparatively unspoiled and the government has done a good job resisting the pressures of development of Hanoi’s downtown area.

More Paris than Seoul

I had the strong sense that Hanoi has the potential of looking more like Paris than Seoul or Singapore in the future. Cities like Paris have many charms but the consistent density and height of its buildings reinforce its appeal and identity. The low-rise condition of Hanoi makes the city seem more humane and beautiful.

The other feature of the view that amazed me was how much greenery there already exists in Hanoi. Two factors contribute to this: tree-cover along major streets and trees that line the numerous mini-lakes you find around Hanoi. You don’t really realize how many lakes there are in Hanoi until you see the satellite image of downtown Hanoi. In the image below, I have indicated with stars all the lakes in the downtown area. The yellow star indicates Hoan Kiem Lake which is by far the most important and beloved lake in Hanoi and represents the spiritual center of the city. Once you can look past the weathered buildings and the ubiquitous motorcycle traffic, you realize that water, trees and nature seem to be at the heart and very identity of Hanoi.

Seoul: a failed model

If you look at Seoul, there are many relics from the past dotted around the city. You have the royal palaces, the gates to the walled city and names of places from the past city fabric buried under the new infrastructure. But rarely do they have space to breath. For example, you have the massive, ugly, Rafael Viñoly-designed monster, the Samsung Jongno Tower, towering over and suffocating Boshingak, the ancient building that houses the bell that announces the start of the New Year. In the history of Seoul’s development, growth and modernizing were given high priority over preservation and heritage. Hanok, the traditional Korean houses which were pervasive all throughout Seoul, were viewed as inferior and backwardly and replaced by concrete “A-pa-tu” apartment blocks. It is ironic that Hanok’s are now making a comeback. Jongno and Cheongyecheon, at the heart of the city were given over to the development of high-rise office blocks, and the identity of Seoul was gradually lost. What’s the point in belated attempts to recover the heritage when it has been lost already?

Ugly Seoul

The danger is replicating the Seoul model elsewhere. It is a failed model that is lopsided towards only serving growth and economy and not the social and cultural well-being of its inhabitants. If urban planning and design are taken only as engineering exercises, the solution will be Seoul. But the city is not an engineering project. Even more so when that city happens to be the capital of a nation. The engineering approach is the easy thing to do: to forecast growth and model housing and infrastructure needs and configure the city to efficiently handle those growing needs. In an unintentional imperialistic gesture, Korean or Japanese engineers will develop Hanoi based on what they know and experienced – in the image of the likes of Seoul, Tokyo. They cannot dream what Hanoi can be.

If you start thinking about all the issues that need to be considered, the mind goes into a state of overload and paralysis. One needs to consider the issues of what to preserve, how to implement regulations, how to solve the traffic, transportation and motorcycle issue, how to promote development… and the list goes on.

People First

The solution may be simple: put people single-mindedly first. This seems to have worked well for Bogata, which emerged from a crime-stricken capital of a civil war-torn country, into a city that has one of the best transportation infrastructure and urban bicycle programs in the world under the brief tenure of Mayor Enrique Peñalosa (1998-2001). The lesson here is, it’s still ok dream big and to imagine a better future. But is takes an enormous amount of courage and leadership.

What to do in Hanoi? At the very least, Hanoi can freeze or restrict development in the downtown area for the next 20 years. In 20 years, the Vietnamese economy will be much stronger, and at a point where they will have the means as well as the methods to do a much better job caring for the cultural heritage embodied in Hanoi. Though painful now, the future generations of Hanoi and Vietnam will thank us if we do that.

Think Different

Most developing nations can only see into the short-term future, and end up sacrificing their heritage for development and growth. All the developed cities in East Asia and Southeast Asia attest to this. Hanoi can be different. It has the potential of becoming the only remaining well preserved, sustainable gem of a city in all of Asia.

Encouraging is the fact that in Hanoi, both national, local officials and academics understand this already. But there is mounting pressure from the private sector to develop and tap the real-estate value of downtown. Once you open that tap, Hanoi will likely see the unpleasant effects flooding in uncontrolled urban development on top of the natural flooding it experiences regularly.

The challenge here is to balance preservation, quality of life, urban identity with the pressures for growth and development. This is something I’ll be thinking very hard about for the next year, as our team works hard on developing the Master Urban Plan for the Hanoi Capital.

A good place to start is by first listening to the people of Hanoi.

* For you tech-heads out there, For the panorama photo at the top of this pose, I used the “File > Automate > Photomerge…” feature in Photoshop CS3, which did the painless job stitching my photos together. I found some interesting panoramas while doing some research into how best to stitch my photos together.

JINA Architects

I formally started working at JINA Architects on September 1, as an Associate Partner.

After a 9 year hiatus, I am back in architecture. Well not quite. It’s urbanism. JINA Architects is a more than a design studio. It’s currently has about 140 staff, a huge growth from having just over 30 a decade ago. Under the management of Eliot Bu (blog / mostly in Korean), it has transformed from just another architecture studio, doing mostly commercial and academic buildings, to now consulting for local and international government clients on urban design issues.

The key to its success? Design Knowledge. With any consulting practice, the key is consolidating and managing knowledge. In the case of JINA, knowledge enables the analysis of legal codes and policy that govern urban design practice. Corporations and architectural practices see the building code as a constraint they have to “deal with”. The government see the building code as a tool for regulating the quantity and quality development. And hence the lack of communication between the two. When you have a deep knowledge of codes then you can act as a medium between the two seemingly opposing entities, and the role that JINA has carved out for itself.

In the US and Europe, non-profits function to collect, analyze data and consolidate knowledge. These non-profits provide politically neutral facts that both businesses and policy makers have equal access to. Korea hasn’t reached that stage yet, with knowledge being held in closed government institution or corporate think tanks. Yet, this is one of the ultimate goals of JINA – to create a non-profit: to collect, analyze and provide access to urban design knowledge and through it to influence the quality of life and in turn, and as corny as it sounds, to change the world.

What is my role in all this? Eliot invited me to join JINA to head the project to develop the Master Urban Plan for the Expanded Hanoi Capital which they were finally officially awarded Sept 23.

Am I qualified? My lack of urban design experience surely would pose a handicap. In the words of Eliot, this is the exact reason I was offered the job, apparently. Urbanism is more than engineering and construction. It’s about the lives of people and hence more infinitely complex, and in dire need of a new approach. He wanted an outsider, untainted by ingrained urban design practices to seek a new approach that incorporates the wide range of expertise that have typically been left out.

For the Hanoi project we have experts in energy policy, international affairs, marketing, sustainability, urban sociology, cultural studies, clean energy development, Vietnam legal system in addition to local experts providing their perspective on how a city should be developed.

This a new approach to urbanism that hasn’t been attempted before and I am caught between fear and dread and shear excitement and optimism that I have been lucky enough to have been offered the opportunity to participate in such a history event of developing a master plan for a city.

We will be changing the lives of the millions in Hanoi. And I know already that Hanoi is a city that will change my life. I have to believe it is a calling, and I am humbled.

I won’t be moving to Vietnam as the title might suggest. But I will be making frequent visits to Hanoi. The title’s just a play on the last time I posted about a new job, New City, New Job. That time, I found a city and then found a new job. This time I found a new job which found a city.

Central Library, Seattle, USA (Rem Koolhaas, OMA)

How does a public library cope in a digital age? How does a physical space handle a virtual classification system such as the Dewey Decimal system, and continuously changing needs?

In the Seattle Public Library’s Central Library, designed by Rem Koolhaas / OMA, books stacks run in a spiral space AKA The Book Spiral (very cool diagram), with removable numbers in the floor so that the library is flexible enough to “learn” and adapt to new needs.

The library embodies many other noteworthy principles that you can find in OMA’s original 1999 concept book for the library.

It’s a space that exemplifies Stewart Brand‘s notion of “How Buildings Learn”.
