Energy Generating Pavement Hits the Streets

Keywords: eco-technology
Source: Pavegen, World Architecture News


According to inventor Laurence Kemball-Cook a paving stone on a busy street is stepped on by more than 50,000 pedestrians everyday and he’s seen the light by harvesting that pedestrian power. Every time the rubber Pavegen stone is stepped on, it flexes 5mm and the dynamo technology stores the kinetic energy produced.

The Pavegen System could power lights, computers, automatic doors and ticket machines at tube stations information displays, street lighting, shop frontages, train and bus timetables and wayfinding solutions.

The slab glows when stepped on indicating that energy has been generated to users. Five paving slabs distributed over a section of a pavement will provide sufficient power to illuminate a bus information panel overnight.

Details:
- Retro-fitted into pavement/ flooring in either interior or exterior spaces.
- The public can actively take part in the energy saving process themselves and there is a strong visual link between the slab and a sustainable attitude.
- Depending on the application, the buy back period can be 1 year or less.

Power:
- Each slab generates 2.1 watts per hour when located in an area with high footfall. Based on a hit rate of a footstep every 4-10 seconds.
- Testing at trial sites has shown that 5 hours of walking at peak time will generate enough power to illuminate a bus stop for over 12 hours.
- 5% of the energy generated per footstep is used to illuminate the central low energy LED lamp.
- Energy is stored within Lithium Polymer batteries: opt. A: 1 battery per 5 unit or opt. B: One battery per unit. Depending on functionality of system.

Materials:
- Top surface: recycled rubber car tyres, internal components: recycled aluminium and the exterior housing is marine grade 316 stainless steel.
- Toughened clear glass with an optical film.

Durability:
- The system requires annual servicing and is designed to withstand 5 years of use equating to 20 million steps in interior and outdoor environments.
- Removable gear tray allows hassle free servicing taking just minutes.
- Engineered to withstand harsh winter conditions without corrosion.

Vandalism:
- Anti-tamper stainless steel bolts are used to prevent unauthorised personnel accessing unit.
- Shock absorbing dampeners to prevent damage to mechanism when large vehicles and high impacts affect the pavegen slab.

Installation:
- Retro-fitted into pavement/ flooring in either interior or exterior spaces.

Colours:
- Available in a variety of colours including grey, red, blue and other mixes.
- Custom branding options: To promote your brands sustainability credentials, Logos can be added to central lamp as shown or etched onto glass.

Trials will take place in several locations throughout the UK in early 2010 with local authorities, schools and airports. Pavegen was designed by Laurence Kemball-Cook who is director of Pavegen Systems ltd. Laurence worked on sustainable blue sky research lighting projects while working as an Industrial Design engineer at Eon UK plc. Pavegen is developed in conjunction with Loughborough University and Advanced leds ltd over a two year period.

Solar Powered Shoes



Keywords: green-technology
Source: eccoterre

Using the included solar cells and LEDs, any set of sneakers can be quickly finessed into surreal garden or street lighting. The kit comes in two sizes—kid and adult—and is available with white or colored (”mood-changing”) lights. Toss one on the ground to illuminate the doorway of your home at night, or fling a pair into a tree—in the spirit of shoe-tossing—to puzzle passers-by.

Both entries of this week are related to the new energy generating technology. Interestingly, both technology look at improving the walking experience of pedestrians, and transform the walking energy into electricity. This idea is great in that it not only create another way to generate electricity, but the energy generated is directly used for improving the pedestrians' walking experience, which may further more encourage more people to use walking as their priliminary means of transportation.
These two designs also call up our attention on much energy we used on lighting the streets at night. It is a inconsiderable amount of energy but for the safty reason we cannot it. Generating electricity by pedestrians themselves solve the problem of keeping street lights on all the time. Maybe we can extend this techonoly even to cars and other vehicles, build in electricity generating panel on the streets and highway so that light only turns on when there are cars passing by.

Sun Valleys in 2010 Shanghai World Expo

Source: Inhabitat, Shanghai World Expo


This incredible Sun Valley is one of a six giant funnel-shaped canopies that are currently springing up in Shanghai in preparation for the 2010 World Expo. When they are all completed they won’t just be a pretty sight – the towering LED-studded structures will also collect rain water and act as massive sun collectors that filter daylight to the causeway and levels below.

70 million visitors are expected to attend the upcoming World Expo in Shanghai next May to view the myriad of dazzling, green-themed international pavilions that will be on display. Construction on these eye-catching Sun Valleys is expected to be completed by the end of this year, and the main cone has has already been lit up at night to the bedazzlement of city residents.

The Sun Valleys will serve as hubs for the event and will cover the Expo Boulevard, a multilevel 1 km walkway that is the largest piece of real estate for the festival. Each of the six cone-shaped valleys stands 40 meters tall, and is constructed from steel and plastic. The sun valleys will funnel daylight to the levels below, and will also be used to collect rainwater, which will then be filtered and used throughout the grounds for irrigation purposes. The giant membranes will also shade the walkway below to help moderate the temperature for visitors.

Unique Features:

The Expo Axis is about 1,000 meters long and 110 meters wide with a total construction area of nearly 250,000 square meters. It employs new architecture style to be a semi-open structure, two layers underground and two layers aboveground. The roof design uses giant light cable-membrane structure, like white clouds floating in the blue sky.

In the whole structure, the 6 cone-shaped giant “Sun Valleys” constitute the most striking feature. The “Sun Valleys”, as the name suggests, are where the sunshine is collected. These steel structured “Sun Valleys” will be longitudinally distributed at the entrances and center areas of the Expo Axis.

Ecological Example:

△ Green Space Underground

The unique profiles of “Sun Valleys” help to disperse sunshine and air into the underground, not only improving air quality, but also saving energy consumed by the artificial lighting. During the Expo, the “Sun Valleys” will also be decorated with colorful plants. Carefully arranged, it will become an attractive ”underground garden” where visitors are unwilling to leave.

△ Automatic Regulation of Indoor Temperature

The employment of eco-technologies will achieve comfortable and pleasant interior environment for the Expo Axis. Under the giant public walkways lie 700-kilometer long pipelines for the ground source heat pump system achieving the role of heating and cooling effect with natural resources. In addition, as the Expo Axis leads to the Huangpu River, the river water can be introduced to regulate indoor temperature as the cooling and heating source.

△ Self-cleaning with Rainwater

Like the concept of rainwater collection in other pavilions, every “Sun Valley” is covered with a wide mouth vase-shaped circular glass curtain, which not only offers a better see-through effect, but more importantly collects rainwater as well. Substantial rainwater is stored in the basement. The collected rainwater will go through a series of filtration sections and become applicable for serving the “Sun Valley” areas, and perimeter pavilions for irrigation and flushing purposes.

Envision Beijing’s Sustainable City Center

Keywords: urban planning
Source: inhabitat


Skidmore, Owings and Merrill (SOM) was recently awarded the contract to create a stunning new Central Business District in Beijing. The project will integrate into the existing downtown urban district and will improve transportation infrastructure while introducing energy-efficient buildings green public space. The plan also provides a framework for new sustainable growth that would result in eliminating 215,000 tons of CO2 per year, which is the equivalent of planting 14 million adult trees.

SOM is well known for its architecture and urban design projects, and is also responsible for San Francisco’s Treasure Island Redevelopment Plan as well as the plan for Jumiera Gardens in Dubai. Their plan for Beijing’s new CBD calls for the creation of three new areas – the Cultural, Chaoyang, and the Gateway Districts, which will be anchored around new parks and green boulevards. The CBD will comprise a network of smaller, more walkable city blocks to encourage pedestrian travel and time spent in the expansive downtown parks system. Additionally, all of the streets will be built to accommodate safe bicycle travel.

A new streetcar system has been proposed to link all of the new areas with existing districts and popular destinations, providing commuters with easy access to high speed rail service. Updated transportation infrastructure will also include express commuter rail service between the Beijing Capital International Airport, the CBD, and high speed rail service to Beijing South Station.

SOM’s redevelopment plan also defines strategies for growth and expansion. They have created a framework for new infrastructure and high performance buildings that will enable the city to grow in a more sustainable manner. If implemented, the plan could reduce energy consumption within the district by 50%, reduce water consumption by 48%, reduce landfill waste by 80%, and result in a 50% reduction in carbon emissions.

SOM’s exciting new plan combines many of the necessary elements of a sustainable city – transportation, open space, pedestrian and bike friendly streets, and energy-efficient buildings. The Beijing CBD Administration Committee has stated that the plan would “enable China’s capital city to grow as a global center for commerce, yet be a green and ecological setting for healthy life.”

Ancient Church Renovated into Modern Bookstore

Keywords: Renovation
Sources: Inhabitat

Whether you’re religious or not, this old Dominican church will certainly bring you the enlightenment you’ve been seeking. After months of renovation this magnificent structure originally constructed in 1294 has opened its doors to the public as a “brand new” bookstore in the heart of Maastricht. A superb example of adaptive re-use, the Selexyz Dominicanen infuses rich and historic architecture with plentiful shelves ripe with information.

Dating back to the 13th century, the structure was a Dominican church until Maastricht was invaded by Napoleon in 1794 and the group was forced out of the country. Since that point it has been briefly used as a parish, then a warehouse, then an archive, then a giant parking lot for bicycles (not such a terrible idea) and finally made over into a bookstore.

Led by architecture firm Merkx + Girod, the new installations are highlighted by a towering, three-storey black steel book stack stretching up to the stone vaults. The highest shelves are reachable by lift or by a set of stairs within the sleek, well-made stack. The views provided from the top shelf along the nave of the church are nothing short of uplifting.

At the back of the church customers and visitors can sit and admire the beautifully renovated 14th century ceiling frescoes, or chat over a cup of coffee in the café situated in the former choir. In a bit of humor the bookstore also installed a cross-shaped reading table where anyone can sit and flip through the magazines and newspapers kept in the slats of the table. So far the design has won the Lensvelt de Architect Interior Prize, and in 2008 The Guardian called it the
“best bookstore in the world”.

Selexyz Dominicanen belongs to the popular Selexyz chain and maintains a wide selection of books across all subjects, even boasting a sizeable collection of books in English. As more and more churches are being abandoned due to redundancy, maybe this is something for Barnes and Noble to think about…

Beijing 798 Art Zone


Keywords: Renovation, Art Loft

Sources: Wikipedia, Beijing 798 Official Website

Similar to Mass MoCA and many other comtemporary art loft space converted from old factory house, Beijing 798 Art Zone is the largest comtemporary art community in China. Located in the old Fashanzi factory complex, Chaoyang District of Beijing, 798 houses a thriving artist community, among 50-year old decommissioned military factory buildings of unique architectural style. It is often compared with New York's Greenwich Village or SoHo, but faces impending destruction from the forces driving Beijing's urban sprawl.

History of the Factory House

The Dashanzi factory complex began as an extension of the "Socialist Unification Plan" of military-industrial cooperation between the Soviet Union and the newly-formed People's Republic of China. By 1951, 156 "joint factory" projects had been realized under that agreement, part of the Chinese government's first Five-Year Plan. However the People's Liberation Army still had a dire need of modern electronic components, which were produced in only two of the joint factories. The Russians were unwilling to undertake an additional project at the time, and suggested that the Chinese turn to East Germany from which much of the Soviet Union's electronics equipment was imported. So at the request of then-Premier Zhou Enlai, scientists and engineers joined the first Chinese trade delegation to East Germany in 1951, visiting a dozen factories. The project was greenlighted in early 1952 and a Chinese preparatory group was sent to East Berlin to prepare design plans. This project, which was to be the largest by East Germany in China, was then informally known as Project #157.

The architectural plans were left to the Germans, who chose a functional Bauhaus-influenced design over the more ornamental Soviet style, triggering the first of many disputes between the German and Russian consultants on the project. The plans, where form follows function, called for large indoor spaces designed to let the maximum amount of natural light into the workplace. Arch-supported sections of the ceiling would curve upwards then fall diagonally along the high slanted banks or windows; this pattern would be repeated several times in the larger rooms, giving the roof its characteristic sawtooth-like appearance. Despite Beijing's northern location, the windows were all to face north because the light from that direction would cast fewer shadows.

The chosen location was a 640,000 square metres area in Dashanzi, then a low-lying patch of farmland northeast of Beijing. The complex was to occupy 500,000 square metres, 370,000 of which were allocated to living quarters. It was officially named Joint Factory 718, following the Chinese government's method of naming military factories starting with the number 7. Fully funded by the Chinese side, the initial budget was enormous for the times: 9 million rubles or approximately 140 million RMB (US$17 million) at today's rates; actual costs were 147 million RMB.

Ground was broken in April 1954. Construction was marked by disagreements between the Chinese, Soviet and German experts, which led at one point to a six-month postponement of the project. The Germans' harshest critic was the Russian technology consultant in charge of Beijing's two Soviet-built electronics factories (714 and 738), who was also head consultant of the Radio Industrial Office of the Second Ministry of Machine Building Industry. The disputes generally revolved around the Germans' high but expensive quality standards for buildings and machines, which were called "over-engineering" by the Russians. Among such points of contention was the Germans' insistence, historical seismic data in hand, that the buildings be built to withstand earthquakes of magnitude 8 on the Richter scale, whereas the Chinese and Russians wanted to settle for 7. Communications expert Wang Zheng, head of Communications Industry in the Chinese Ministry of National Defense and supporter the East German bid from the start, ruled in favor of the Germans for this particular factory.

At the height of the construction effort, more than 100 East German foreign experts worked on the project. The resources of as many as 22 of their factories supplied the construction; at the same time, supply delays were caused by the Soviet Red Army's tremendous drain on East Germany's industrial production. The equipment was transported directly through the Soviet Union via the Trans-Siberian railway, and a 15 km track of railroad between Beijing Railway Station and Dongjiao Station was built especially to service the factory. Caltech-educated scientist Dr. Luo Peilin, formerly head of the preparatory group in 1951-1953, was Head Engineer of Joint Factory 718 during its construction phase. Dr. Luo, now retired in Beijing, is remembered by his former colleagues as a dedicated perfectionist whose commitment to the obstacle-strewn project was a major factor of its eventual success.


Artistic Rebirth:

The Dashanzi factory complex was vacated at around the time when most of Beijing's contemporary artist community was looking for a new home. Avant-garde art being frowned upon by the government, the community had traditionally existed on the fringes of the city. From 1984 to 1993, they worked in run-down houses near the Old Summer Palace (Yuanmingyuan) in northwestern Beijing, until their eviction. They had then moved to the eastern Tongxian County (now Tongzhou District), more than an hour's drive from the city center.

Then in 1995, Beijing's Central Academy of Fine Arts (CAFA), looking for cheap, ample workshop space away from downtown, set up in the now defunct Factory 706. The temporary move became permanent and in 2000 Sui Jianguo, Dean of the Department of Sculpture, located his own studio in the area. The cluttered sculpture workshops have always remained open for visitors to peek at the dozens of workers milling about.

In 2001, Texan Robert Bernell moved his Timezone 8 Art Books bookshop and publishing office (founded in 1997) into a former factory canteen; he was the first foreigner to move in. One of Timezone 8's early employees was fashion designer Xiao Li, who along her husband, performance artist Cang Xin, helped artists secure and rent spaces in the area.

Through word-of-mouth, artists and designers started trickling in, attracted to the vast cathedral-like spaces. Despite the lack of any conscious aesthetic in the Bauhaus-inspired style, which grounded architectural beauty in practical, industrial function, the swooping arcs and soaring chimneys had an uplifting effect on modern eyes, a sort of post-industrial chic. At the artists' requests, workers renovating the spaces preserved the prominent Maoist slogans on the arches, adding a touch of ironic "Mao kitsch" to the place.

Later that year, Mr. Tabata Yukihito from Japan's Tokyo Gallery set up Beijing Tokyo Art Projects inside a 400-m² division of Factory 798's main area; this was the first renovated space featuring the high arched ceilings that would become synonymous with the Art District. BTAP's 2002 opening exhibition "Beijing Afloat" (curator: Feng Boyi), drew a crowd of over 1,000 people and marked the beginning of the popular infatuation with the area.

In 2002, designer artist Huang Rui and hutong photographer Xu Yong set up the 798 Space gallery next to BTAP. With its cavernous 1200-m² floor and multiple-arched ceilings at the center of Factory 798, it was and still is the symbolic center of the whole district. (Huang and Xu since designed at least seven spaces in the area and became the prime movers and de facto spokespersons of the District.) A glass-fronted café was set up in the former office section at the back of the 798 space, opening into a back alley now lined with studios and restaurants such as Huang's own At Café, and Cang Xin's #6 Sichuan restaurant, the area's "canteen".

In 2003, Lu Jie set up the Long March Foundation, an ongoing project for artistic re-interpretation of the historical Long March, inside the 25,000 Li Cultural Transmission Center . Around that time, Singapore-owned China Art Seasons opened for display for pan-Asian art, and was one of several new galleries setting up at that time.


There are many vibrant art communities like Beijing 798 are developing in different cities in China, such as the 40 Moganshan Rd in Shanghai, Old Hangzhou Silk Factory in Hangzhou. These art communities take the space of our communist factory house, which gave a rebirth of these deserted factory building. By using these architecture structures which were built under strong influence of the communist ideology, the artists inside also developed a new kind of retro art style that looks back at the communist culture through the glass of contemporary China.

Mass MoCA

Keywords: historic preservation and renovation
Sources: Mass MoCA, Bruner/Cott + Associates, Inc.

This spring, my intro architecture studio class took a field trip to Mass MoCA, a great example in how old factory buildings are renovated and transformed into a contemporary art place.

Mass MoCA locates in North Adams, MA. Its site was the former factory building of Sprague Electric Company. North Adams was a industrial town in history. Pririor to the Sparaque Electric Company, the site had been used for a mill factory and print work factory. Here is a complete history of Mass MoCA: click

MASS MoCA was opened in May, 1999. It is housed on a 13-acre campus of renovated 19th-century factory buildings. It has 19 galleries and 100,000 sq ft (9,300 m2) of exhibition space. In addition to galleries and performing arts spaces. MASS MoCA also rents space to commercial tenants.The complex occupies nearly one-third of the downtown business district.

By coupling the versatility and size of its spaces with the latest digital, fiber optic, and new media technologies, MASS MoCA is able to present and catalyze the creation of works that can be shown nowhere else in the world. Actually, its unique site gives more meaning to the works housing in the museum, expanding and redefining the nature of contemporary art.

And no wonder the Wall Street Journal commented on Mass MoCA renovation project: I have seen the future and it's Mass MoCA.
