Wear Your Grass on Your Sleeve

Grass Skin Rug by earthwormstudio.

It's like a bear skin rug - without the bear. Hopefully the bear left behind is out there somewhere, being a bear. Instead, curl up and watch your favorite movies on a nice piece of the countryside. The right patch of grass can be downright comfortable and even adds a great splash of green to any naturally day-lit room. And why stop there? Strike a pose in your best Grass Yeti suit.

The grass family is one of the most abundant plant forms on earth. It is important in every ecosystem it inhabits - providing a vital energy source to the food chain around it. It also helps to filter rainwater into the soil below and even holds the top layer of earth in place. And it's entirely renewable for the cultavatively curious. Why wouldn't you want some grass walls, floors or clothes?

How Tall is Too Tall

Photograph by Declan McCullagh Photography.

We often say that we should follow the biological examples set forth by nature when we design. But what happens when our ambitions are greater than the limits of natural design? Take the height of a tree for example - in many cases, the taller the tree, the more energy it can harvest. Since trees naturally grow close to one another, they need to grow vertically to reach the sun amidst it's neighbors. The taller the tree grows, the more access to life-giving sunlight it has. However, any successful quest for the sun would surely be folly - and nature knows it. At the upper limits of a trees structural and functional capacity there is a point where the need for more height becomes obsolete. Growing taller would mean too much energy is invested in moving water from the roots to the upper branches and leaves. The quest for height is counteracted by the physical limits of the trees natural capabilities and thus, an upper limit is reached.

Coastal Redwoods via Coastal Care.

The tallest tree now generally accepted as the tallest living is a 379.1 ft (115.56 m) Coast Redwood in Redwood National Park, California. The height of the Coast Redwood Tree is within the upper limits of a trees natural boundary. Any taller, and the energy required to function would be too great to validate it's successful existence. What are the upper limits of buildings?

The Burj Khalifa.

The tallest building in the world is the Burj Khalifa in Dubai, UAE. It measures 2,717 ft (828 m) tall. The building, designed by Skidmore Owings Merrill, is undeniably a marvel of modern design and construction. The sheer enormity of the structural, mechanical, and planning needs of a building this tall alone warrant it's status as one of humankinds greatest achievements. The structural system of the building was an elegant solution to excessive height. According to Gulf News:

"To support the unprecedented height of the building, the engineers developed a new structural system called the ‘buttressed core', which consists of a hexagonal core reinforced by three buttresses that form the ‘Y' shape. This structural system enables the building to support itself laterally and keeps it from twisting."

The strength of this revolutionary system allowed the engineers to add more floors than building was originally designed for. The building will apparently also use solar power to heat 140,000 litres of water a day for use in residential and commercial use in the tower. However, the building still consumes a massive amount of resources to operate. Consider the comparison by The Red White and Green:

• Water: Around 250,000 gallons of water a day
• Electricity: At peak times, roughly 40,000 kilowatts — the equivalent of 500,000 100-watt light bulbs burning at the same time
• Raw materials: Nearly 40,000 tons of steel — enough to stretch a quarter of the way around the earth if laid end to end
• Wasted space: The upper 30+ floors are so tiny, they can only be used for storage.

The building is an enormous achievement of excess. Beautiful and terrifying.

But can they become bigger without some type of radical new technology? Can a building of that size exist without consuming more than it takes to operate? Give back even?

The Tower of Babel by Pieter Bruegel the Elder.

A building twice the size of the Burj Khalifa boasts of the idea of reaching for the gods - a true Tower of Babel. A feat that surely will be attempted, and probably even achieved some day. But like the tree before it, will it do something for humanity, the earth, or for something else altogether - our ego and physically awe-inspiring proof of our dominion over this planet. Will the world be better with it, than without it? That's what nature knows. and is trying to tell us. It only allows for something to exist when that something is a both a benefit to itself and everything else around it.

Of Bricks and Bacteria

On average, the kiln-drying process for one brick emits 1.3 pounds of carbon dioxide. Every year, 1.23 trillion bricks are made around the world. The environmental pollution associated with this process totals more than that of all aviation pollution worldwide. Fire-kilned brick has been around for over 5000 years, making it one of the oldest - if not the oldest - manufactured building material in the world. Introduced to the world by the Romans, the technology surrounding brick has changed little over that span. However, as manufacturing and technology increases, the environmental impact of the material is being unearthed. The traditional method has never changed because there was no reason to change it. Now there is. And now you can grow a brick.

Ginger Krieg Dosier, 24 year-old architecture professor with a passion for microbiology, and chemistry, and winner of the Build a Better Brick competition sponsored by Metropolis, has invented a brick manufacturing process that works sans heat. According to Bustler:

"Dosier's process replaces baking with simple mixing, and because it is low-tech (apart from the production of the bacterial activate), can be done onsite in localities without modern infrastructure. The process uses no heat at all: mixing sand and non-pathogenic bacteria (sporosar) and putting the mixture into molds. The bacteria induce calcite precipitation in the sand and yield bricks with sandstone-like properties."

The brick represents a twofold advantage over the traditional methods of kiln-firing. First, the environmental impact. By replacing the most environmentally damaging part of the manufacturing process - the firing - the process is rendered almost entirely natural. The brick relies on the active ingredients to produce chemical reactions to achieve the brick's hardness and strength. Second, again by replacing the firing process, the physical infrastructure required to manufacture the brick has been reduced. Without the need for large firing kilns, the process becomes much more suited to rural and developing areas where a manufacturing operation can be set up quickly, on site and local, and without permanent structures or facilities.

See the whole process of making a brick here at Metropolis.
As a type of unit masonry, the brick lends itself to small-scale and mass production. However, the idea of growing structural components is intriguing. Could the scale be increased, and entire building structures be grown organically from the ground up? Moreover, if the active ingredients were designed to not just activate, but multiply, could we see structures grown with the precision typically reserved for Mother Nature? Strength where required, and lightness where it is not. This would relate very well to the theories of Neri Oxman and iGem Synthetic Biology.

The Library as Vending Machine

There is something mysterious and exciting about walking down a dark narrow library aisle - the stacks closing in over top of you, the dusty smell of aging paper, and the possibility of stumbling upon a book you never even knew existed. This is the experience of silently wandering through countless libraries all over the world. Unfortunately, this experience is also at odds with the fast-paced immediate retrieval experience that is the digital age we find ourselves in currently. Starting your search may be as easy as typing in the broadest definition of the topic, and result in countless digital paths of inquiry - akin to browsing through dusty stacks as organized by Dewey. However, if you know exactly what you are looking for, the ability to narrow down feedback results can be as precise as you can type. Results can be almost immediate - and all from the comfort of your home computer or mobile device. This is the wonder and detachment of the internet and digital information.



The new Joe and Rika Mansueto Library at the University of Chicago has bridged the gap between physical records and digital accessibility with it's "Automated Storage and Retrieval System" that "takes inspiration from commercial inventory techniques". The books and manuscripts are stored in special preservation-condition bins and bar-coded so that the system knows exactly where to send it's robotic retrieval arms for delivery. The user short-circuits the traditional method of library searching, and instead, is greeted by the worlds largest vending machine. Instead of Honeybuns and Cheetos's, pressing B5 will bring you Shakespeare and Darwin.

The technology is indeed highly sophisticated and brings a new level of organization and ease to a process once fraught with uncertainty and confusion. The search for information has become more direct and efficient, however, gone are the days of exploration and tangential discoveries that often lead to new avenues of research. The Joe and Rika Mansueto Library uses an online catalog that allows users to digitally "search" the library holdings. It would be interesting to know if a certain amount of "randomness" could be built into this search so users are given several options to branch out their search. The catalog could have a built-in "I'm Feeling Lucky" function similar to Google's Search Engine, or even a recommendation function similar to Amazon's "User Who Searched for This Product Also Searched For..."

Of Robots and Clouds

In the summer of 2022, Qatar, a small country on the Arabian Peninsula will host the FIFA World Cup. In the summer of 2022, temperatures are expected to reach, as they do now, up to 120 degrees Fahrenheit (50 C). FIFPro, the global football players union stated that temperature extremes such as this "...[do] not provide suitable conditions for a festival of football such as the World Cup". FIFA officials initially stated that the tournament, which is historically played in the summer months of June and July, would be moved to the winter months, but have since stated it would go on as planned during the summer.

Qatar engineers plan to air-condition the host stadiums through energy collected from solar arrays to combat the excessive heat, but also have a new trick up their sleeve: Robotic Clouds. According to a video clip on BBC, The "clouds", constructed of lightweight, inflatable materials, driven by four turbine engines are powered by integrated solar collectors and would be remote controlled to follow the path of the sun, thus "shielding it from direct sunlight and providing a favorable climatic environment" for the stadium.

This robotic cloud may be part of the natural evolution of the "Goodyear Blimp" phenomenon, which began in 1925 as a platform for advertisement and eventually the television and video broadcasting of sports events. Add to this technology the ability to create remote controlled micro-climates, and a new breed of airships is born. One where, as BLDG BLOG notes "the next step in temporary event architecture will be a remote-controlled swarm of rearrangeable horizontal and vertical surfaces, forming ceilings, roofs, walls, floors, ramps, and stairways."

The idea of a technology enabling users the power to control their environment is not a new one, but is still an extremely powerful one. One can easily imagine entire fleets being used to alter entire environments, programmed to mimic the circadian rhythms of far-off regions to enable agricultural production until now rendered impossible due to harsh climates. Or conversely, in a dystopic realization of the technology, climate warfare where fleets of robotic clouds are positioned to disrupt agriculture and other physical and social benefits of the sun.

I am reminded of a scene from the recent The Simpson's Movie where helpless Springfielder's stand trapped under a dome and watch a live feed from their captor on a huge video screen above...

Nature in Architecture by Michael Pawlyn

In this TED Talk, designer Michael Pawlyn of Exploration discusses the advantages of biomimicry for the future of architecture and design. Pawlyn begins by citing a few examples of nature's own inventive ways of adapting to specific climate needs and indeed, makes a very clever analogy out of this evolutionary advantage:

"You could look at nature as being a catalog of product's and all of those have benefited from a 3.8 billion year research and development period, and given that length of investment, it kind of makes sense to use it."

Throughout the talk, Pawlyn uses examples of existing technologies and projects that learn from nature's example and use bio-mimicry to solve what he sees as the three necessary steps to becoming truly sustainable:

1. Radical increases in resource efficiency
2. Linear to closed loop systems
3. Fossil fuel economy to solar economy

Perhaps the most intriguing indictment against us is expressed in Pawlyns second step - the comparison of our current method of resource use versus the way nature does. Our current mode of design, consists of extracting resources, turning them into "short-life products", and then disposing of them. However, this contrasts greatly with the way nature uses resources. In the natural model, everything that is created is used, - the waste generated in one system, is used for energy in another. By altering our current mode of design to a "systems" model, we are able to add value to waste, which is currently now a completely negative by-product.

Buckyball Distraction

Kowloon Walled City

Kowloon Walled City was an urban Chinese island in the British-owned territory of Kowloon, Hong Kong characterized by it's incredible density, labyrinthine structure, and social make-up of pimps, gangsters, and opium dens. Founded as a Chinese outpost in 920 AD, the city was condemned to demolition in 1987 by the government of Hong Kong. It was demolished in 1993 after a six-year eviction process of it's residents. The city-within-a-city became notorious for it's reputation as an urban construction of hell-on-earth and indeed became a walled zone where most people could not enter without a high possibility of incident.

In 1993, prior to demolition, a team of Japanese researchers was allowed to map the interior of the settlement and produced these colorful section diagrams showing both the social and sectional topography. The tangle of activities and spaces show an existence of incredible complexity and spatial relationshio to the inhabitants surroundings. However, as frantic and limitless as the graphic seems, it stands to reason that the true experience of the space was even more extraordinary than illustrated.

Ice-Nine, Or How to Grow Concrete from Bacteria

In Kurt Vonnegut's 1963 satirical novel Cat's Cradle, the protagonist follows the trail of a brilliant researcher's children who hold with them ice-nine - a chemical invention small enough to be carried under the fingernail, but potent enough to freeze all water on earth solid. The element is described as a "seed" that alters the atomic composition of liquid:

"There are several ways", Dr. Breed said to me, "in which certain liquids can crystallize - can freeze - several ways in which their atoms can stack and lock in an orderly, rigid way." That old man with spotted hands invited me to think of several ways in which cannonballs might be stacked on a courthouse lawn, of the several ways in which oranges might be packed into a crate. "So it is with crystals, too; and two different crystals of the same substance can have quite different physical properties."

He goes on to describe the stacking process:

The theoretical villain, however, was what Dr. Breed called "a seed". He meant by that a tiny grain of the undesired crystal pattern. The seed, which had come from God-only-knows-where, taught the atoms the novel way in which to stack and lock, to crystallize, to freeze. "Now think about cannonballs on a courthouse lawn, or about oranges in a crate again", he suggested. And he helped me to see that the pattern of the bottom layer of cannonballs or of oranges determined how each subsequent layer would stack and lock. "The bottom layer is the seed of how every cannonball or every orange that comes after is going to behave, even to an infinite number of cannonballs or oranges."

And of course, the prolific advantages are described alongside the horrific consequences:

And that old man asked me to think of United States Marines in a Godforsaken swamp. "Their trucks and tanks are wallowing", he complained, "sinking in stinking miasma and ooze." He raised a finger and winked at me. "But suppose, young man, that one Marine had with him a tiny capsule containing a seed of ice-nine, a new way for the atoms of water to stack and lock, to freeze. If that Marine threw that seed into the nearest puddle...?" "The puddle would freeze?", I guessed. "And all the muck around the puddle?" "It would freeze?" "And all the puddles in the frozen muck?" "They would freeze?" "And the pools and the streams in the frozen muck?" 'They would freeze?"

In 1963, Vonnegut pondered both the possibilities and the dangers of such technology through dark humor, the absurd, and the profane in this story of invention and the human hands that guide it. In 2010, however, the potency of this allegory is all to familiar as science, theory, and invention is constantly redefining the ability of humans to solve problems.


For the annual iGem synthetic biology contest, a group of students at Newcastle University have engineered BacillaFilla - a type of bacteria that, once inserted into a concrete crack with the proper growing media, will germinate and produce a "mixture of calcium carbonate, levan glue and filamentous cells" that will densify and "activate concrete repair". Eerily, the scientific name for the compound is called Bacillus Subtillus 168. According to the team:

BacillaFilla repairs concrete by producing a mixture of calcium carbonate, levan glue and filamentous cells in the cracks. Once we have applied BacillaFilla spores onto the concrete surface, they will start germinating in the presence of media. Once the cells have germinated, they will start to swarm down the crack. At the bottom of the crack when they reach a high density, they will use subtilin quorum sensing to activate concrete repair. BacillaFilla repairs concrete by 3 different processes:

1. Some of the cells with produce calcium carbonate crystals,
2. Some of the cells will become filamentous thereby acting as reinforcing fibres in the crack and
3. All the cells will produce Levans glue which acts as a binding agent and at the same time it fills up the whole crack.

Interestingly, the bacteria only work through a swarming process whereby the bacteria propel themselves to reach the point of germination. Also, almost in a pre-meditated response to detractors and grey-goo fear-mongers, the team has implemented a genetic "kill-switch" to stop the spread of bacteria.
Of course, the ability to repair concrete from within is as exciting as the potential for a runaway concrete-producing super-bacteria is alarming. Material technologies such as this blur the lines between natural phenomena and synthetic architecture, border on Utopian ideals and science-fictional dystopias, and represent bold new ideas in research and development.

A View of the Pakistan Floods

The Indus River Watershed on August 18th, 2010.

The Indus River Watershed on August 13th, 2001.

The beautiful imagery of this satellite image belies the terrible ongoing event that is causing it. The flooding in northern Pakistan started in mid-July when monsoon rains exceeded expectations and overwhelmed an already overstressed watershed of the Indus River. Since then, the region's population of over 15 million have been terribly affected - millions homeless, over 1,500 people dead, and most with little or no access to proper shelter, sanitation, food, or health care.

The situation is expected to worsen, as more rains are expected in the coming weeks.

There are many ways to get involved. Donate time, money, or expertise to aid organizations or local communities. Spread the word about the event to friends and family. UNICEF has made clean drinking water and food to be priorities among aid divisions. Donate via UNICEF here. The Red Cross lists shelter and medical aid as a major concern for immediate relief needs.

LIVE BLOG - Promoting Green Building Rating Systems in Africa - 2015 Goals

2015 Goals

In the final day of the conference, there were several things left to do. Previously, the group spent two days engaged in discussions and brainstorming sessions. By the third day, it was evident that everyone in the room had a lot of ideas about how to move forward. There were three overarching conference goals:

1. Make commitments, develop elements of a strategy, and create a road-map for achieving those goals.
2. Develop an outline for a continental network supporting the sustainable building industry and professionals, and for assistance in establishing green building councils.
3. Provide recommendations to UN-Habitat on how this can be achieved.

Each country represented at the conference was asked what their specific goals were for the year 2015. The following are individual country goals for 2015:

Uganda: Written green building guidelines for different environmental regions in country.
Nigeria: Establish a GBC. Complete an example building (pilot project).
Tanzania: Integrate green building (re-integrate traditional sustainable building techniques) into codes. Pilot projects for schools, healthcare/clinics, and commnity centers for public awareness. Financial system in place w/industry support.
Malawi: Environmental curriculum in schools (all levels).
Gambia: Sustainable design guidelines.
Cameroon: Grass-roots awareness campaigns at the local level.
Zambia: Implement a GBC and get government commited to green building.
South Africa: Integrate social aspects into rating systems.
Ghana: Involve government and private sector into GBC development.
Ethiopia: Worldwide sharing of knowledge and goals (networking).
Morocco: Complete a pilot project in each sector.
Burkina Faso: Promote traditional methods of green building and integrate into codes/regulations. Create GBC and green building guidelines.
Egypt: Mandate zero-emission codes.
Chad: Develope institutional framework for GBC at a local level and connect to the Africa-wide and global GBC network.
Mauritius: Be self-sustainable in all aspects (energy, food, materials, etc.).
Rwanda: Tax-incentives for green buildings. Awareness campaigns.
Kenya: Increase in demand for green building among developers and the public.

As these goals were discussed, several general themes emerged. There were four broad action-categories that each goal could be attributed to:

Policy Implementation: Codes/regulations. Political support.
Market Transformation: Financial Incentives. Industry Buy-in.
Guideline Development: GBC's. Rating Tools.
Awareness and Education: Curriculum. Pilot Projects. Awareness Campaigns.

LIVE BLOG - Promoting Green Building Rating Systems in Africa - Policy and Finance

How Can National and Local Government Policies and International Programs Encourage and/or Finance the Construction of Green Buildings and Rating Systems?

The United Nations Environmental Program (UNEP) Sustainable Buildings and Climate Initiative is a program that studies and defines the global metrics of sustainable building policies. It is a policy-oriented program and does not deal directly with the technology involved in sustainable building practices. Rather, it explores the financial impact of green building and the industry reaction to the trends. These industry reactions are explored in terms of financial markets and government policy and input.

Niclas Svenningsen of UNEP states that in actual practice, the the long-term cost benefit of sustainable design is not a reality to the construction and development industry when compared to the high cost of initial investment. For it to become real, there need to be mechanisms in place to move the long-term savings of resource-efficient design to the front-end of the finance model. Enter the Stick, the Carrot, and the Tambourine. The stick that will get developers to implement sustainable design practices are policy measures such as the adoption of codes and regulations as well as penalties for under-performing buildings. The carrot, of course, is the opposite and offers tax incentives, and other rewards for well-performing buildings and development. The tambourine, though, is slightly more intangible, but perhaps less policy-oriented and therefore more relate-able to the public. The tambourine involves actions and initiatives that public promote sustainable building practices such as public relations, marketing efforts and awareness campaigns, and educational programs.

However, according to Svenningsen, the bottom line is that sustainable design cannot be promoted as a separate agenda. The concepts and benefits of green design need to be tied to other policy agendas. For example: Schools and offices with better indoor environments have statistically better performance records. Responsibly designed communities have a statistically lower rate of poverty and crime, and have a better public health record. If the benefits are explored and extolled in terms of larger issues, the ability to be implemented within the context of industry and government as a whole, from the top-down, becomes more likely.

In the opinion of the blogger, this is an issue that LEED in the United States has failed to address. Although there are some ties to government and industry, the system as a whole has positioned itself as an actual force within the market, rather than a network amongst it. This has commodified the green building field, and being a commodity, it inherently becomes an extra to the process of design and building. It is not promoted as a part of responsible design practices, rather, it is promoted as an additional service that can be included in a project if the client is able to fund the inclusion of the practices. Little effort is put into incorporating these practices into codes or regulations, and until it is done, "green buildings" will continue to be seen as a privilege instead of the norm.

LIVE BLOG - Promoting Green Building Rating Systems in Africa - Alternatives to Nation-Specific Green Building Councils

UN-Habitat Human Settlements Advisor Robert Kehew.

Alternatives to Nation-Specific Green Building Councils

Although it is clear that the implementation of a Green Building Council is not a solution for instituting sustainable building practices in Sub-Saharan Africa, rather, it is a potential way to create a framework for developing the methods and metrics needed to advance the field of sustainability in Africa. However, a Green Building Council is a complex mechanism that relies on input and involvement from many different players within the building sector - architects, contractors, developers - as well as support from industry and government. So, while many countries in Africa lack formal economies advanced enough to support complex industry as well as battling political systems rife with corruption, the question arises, how small can a nation's building sector be and still support a full Green Building Council?

If there is a correlation between a nation's Gross Domestic Product and the size of a building sector, then the smallest existing GDP's with a full-service Green Building Council are New Zealand and South Africa. The United Nations estimates that the building sector accounts for 5-15% of a country's GDP. According to the World Bank, in 2009 South Africa is second in GDP among African nations behind Egypt, and almost twice that of the next two rankings (Nigeria and Algeria). After this, the number drops precipitously.

If a country cannot support a full-service Green Building Council, are there alternatives? According to Robert Kehew of UN-Habitat and Bruce Kerswill of the World GBC, there are.

Kehew lists Government-sponsored rating systems and Sub-Regional GBC's as options. Government rating systems are able to focus primarily on energy efficiency and can easily integrate simple rating metrics into existing regulations, however, many governments already deal with corruption and other issues that may minimize the importance of sustainable design within the larger political and social context. Sub-Regional GBC's are systems that may straddle several nations that share trading relationships, common codes and regulations, and/or cultural ties. This allows several countries to share cost, responsibility, and benefits. This model, however, also relies on the cooperation and power-sharing between potentially strained political systems and relationships.

Bruce Kerswill of the World GBC recommends a phased approach to growth where larger, more developed nations act as a hub for smaller nations and assist in the development of rating systems and networking. This model requires that the developing country may need to adapt or customize the existing rating tools to suit their individual country-specific needs. This works well where countries share geographic similarities or borders, but may require additional time and effort where similarities or geographic proximity do not exist.

Beyond this, are there more options? The immediate reaction from the writer of this blog is that GBC's may not be appropriate for countries at this stage of development. Where GBC's are systems that help to quantify, coordinate, and track the performance of green buildings (a very simplified definition), they are essentially bookkeeping measures. Where a nation lacks the infrastructure to support this system, it is possible that implementation of educational programs and community awareness campaigns about sustainable concepts and methods may be a better use of resources. Once these ideas and technologies are in place, and the advantages of sustainable design are understood and experienced, it would be a natural progression to then begin to quantify those results.

LIVE BLOG - Promoting Green Building Rating Systems in Africa - What is Appropriate for Africa?

Speaker Akin Akindoyeni

What is Appropriate for Africa? Country-Specific Challenges Facing the Green Building Industry in Africa.
During this session four panelists - each representing a different country in Africa - were posed a set of questions and asked to answer in terms of their own country-specific experience and ideas. Discussion was then opened to audience members after panelist response. This was easily the most interesting session of the day, as it highlighted many commonalities between the different countries and participants, but also raised many cultural issues that were unique among them. This was a long session, so highlights in note form below.

Panelists:
Akin Akindoyeni, Chairman - Council of Registered Builders of Nigeria, Nigeria
Dr. Kamugisha Byabato, Engineer and Lecturer - Tanzania Energy Research Institute, Tanzania
Tony Lee Luen Len, Mauritius GBC, Mauritius
Elijah Agevi, Kenya Private Sector Alliance, Kenya

QUESTION 1: WHAT ARE THE KEY CHALLENGES FACING GREEN BUILDING IN AFRICA?
Akindoyeni: Need to educate the general population on the consequences forseable in the future if the current building trends are maintained. Genral population does not understand that current actions will have negative consequences.
Agevi: Priorities. 70% of Africa is poor, and most need access to other basic life-needs (shelter, job, education, access to water, food, and proper sanitation) before sustainable building technologies and strategies can be considered.
Len: Out-of-sight, out-of-mind. Fear of unknown (lack of understanding of green concepts and the desire not to build out of comfort zone). General population has little participation in development and the decision-making process.
Byabato: The concept of green design is not unknown to Africans. Traditional building techniques are inherently sustainable (solar shading, building orientation, water collection). Africans have a desire to be modern, but in the international sense - not in through a contemporary African perspective. The move to modern has pushed away the traditional techniques in lieu of the international style which is not appropriate in Africa (environmentally, culturally, or politically). These new post-colonial technologies systems, and governments are not reconciled with the traditional.

-COMMENTARY OPEN TO AUDIENCE-

Representative from Cameroon: Too much concern for profit in the short-term.
Representative from Sudan: (Comments specific to post-conflict nations). Lack of infrastructure and facilities. Post-conflict nations just want to re-build. Desire for most immediate solution. Cheap. Fast. Familiar. Many post-conflict countries are funded by outside sources, so they may be subject to the agendas of the funding organizations/countries.
Representative from Ghana: No advocacy from the intellectual class. Politicians and government are the elite that push development. Action needed at the local level. No action from the top-down.

QUESTION 2: WHAT NEEDS TO CHANGE IN TERMS OF GREEN STANDARDS?
Akindoyeni: Change needs to happen at the elite level. If a country has a building code, it needs to be updated AND enforced. Education needs to occur at all levels. Change needs to be forced (later redacted during discussion to use the word enforced). People who do not understand, will not change.
Agevi: Change the mind and way of thought about sustainability (cost vs. net benefit) at all levels. Aggressive awareness campaign aimed at all stakeholders. Tax incentives. Mainstream standards and codes need to be adopted and enforced. Solutions must be sensible and cost-sensitive.
Len: Update building codes as per region. No more one-size-fits-all set of regulations.
Byabato: Look to traditions. "Slums were not created by God. At independence, only the leaders changed - the rules did not. Africa is still playing by rules created for them, not by them." Use public buildings as public examples. All new buildings should be built by these [updated] standards. No exceptions.

-COMMENTARY OPEN TO AUDIENCE-

Representative from Egypt: Do not force the poor. They are the ones who need access to sustainable design the most, but forcing them will not work. Lead by example.
Agevi Response: The biggest issue with codes and regulations is enforcement.
Byabato: (Response to earlier comment by Sudan - no infrastructure, etc.) "The advantage of underdevelopment". If there is no inherent infrastructure or institutions then there are no physical barriers to new development strategies - only mental and cultural.

QUESTION 3: WHAT CAN REALISTICALLY BE ACHIEVED IN THE NEXT FIVE YEARS?
Agevi: Mainstream awareness. Audits on existing buildings and industry stakeholders. Change in language (i.e. sustainable as part of normal design, not an extra). Regional thinking. Need champions.
Len: GBC set up fully in Mauritius. Pilot projects.
Akindoyeni: Building profession to cooperate in sustainable design practices. Use rating systems as a campaign tool. Example buildings and best-practice examples.
Byabato: Engage and involve financial institutions in building practices. Make financial institutions into stake holders.

LIVE BLOG - Promoting Green Building Rating Systems in Africa - Introductory Session

The conference assembly hall with attending members.

The UN-Habitat Conference on Promoting Green Building Rating Systems in Africa opened this morning at the UN Compound in Grigiri, Kenya. Representatives from twenty African nations, seven countries from Europe, Asia, and North America, and delegates from the United Nations were in attendance as Inga Bjork-Klevby, Deputy Executive General of UN-Habitat welcomed the assembly and introduced the goals of conference:

"In the United States, the building industry is responsible for approximately 40% of the green-house gas emissions for the country. At present, there are no figures for African cities. How do you measure the effectiveness of green building strategies where little or no record is kept? The purpose of this conference is for participants to understand the available options in terms of sustainability so they can make informed decisions. It is not the responsibility of the people, but of you, the building industry - architects, engineers, builders, developers, and legislators - to generate and organize ideas to meet the challenges of the future of urbanization."

Tirop Kosgey, Permanent Secretary of the Ministry of Housing in Kenya echoed the sentiments of Bjork-Klevby:

"We need to harness the full potential of technology to address the effects of climate change and to build sustainably, to build smart infrastructure, and create robust building codes. We need to move beyond advocacy, and put into place, legal and legislative standards."

The opening remarks by both Bjork-Kevby and Kosgey were clear: accountability would be placed squarely on the shoulders of the building industry, and the only way to truly promote sustainable design in Africa is through collaboration, education, and the incorporation and enforcement of legislative guidelines.

LIVE BLOG FROM NAIROBI - Promoting Green Building Rating Systems in Africa

Architecture for Guerillas will be blogging live from Nairobi, Kenya on the UN-Habitat Conference on Promoting Green Building Rating Systems in Africa. The objective of this conference is to familiarize industry professionals in Africa with an experience-based perspective on sustainable buildings, best practice examples of green buildings and technology, and the implementation of rating systems to objectively measure and track sustainable building technology and trends. The conference also seeks to introduce and encourage a global network of professionals dedicated to developing these tools.

Stay tuned for updates and commentary.

The Archigram Archival Project Now Online

Don't wait. Just click here to see it.

In a surreal world not so far away, Warren Chalk, Peter Cooke, Dennis Crompton, David Greene, Ron Herron, Michael Webb and countless collaborators formed the group Archigram. Part architectural visionaries, part cultural commentators, and part machine, the group would go on to create a technicolor utopia of projects that walked off of the page and presaged the future collision of architecture, technology, and the society of tomorrow. In an exhaustive effort of archiving, research, and archi-sleuthing, the architectural research group EXP at the University of Westminster have published the Archigram Archival Project - an online repository of over 200 examples of the groups work. The project was funded by the Arts and Humanities Research Foundation. If anyone has searched for the work of Archigram in the past, many will understand the pain and frustration at the dearth of available information on the Archigram projects, but this website opens a new door into the archi-mechanical techno-utopias of a truly unique architectural movement.

How to Make Light Transmitting Concrete

Instructables - a member populated web archive of do-it-yourself tutorials - has a step-by-step guide on how to make light transmitting concrete using several simple materials. By setting fiber optic wires into a clay mold and pouring concrete around the assembly, the result is a solid disc (or other clever shape!) with the ability to transmit light through it's mass. The effect is quite beautiful. The traditional weight of the concrete is never lost and still remains inherent in the object, and yet a light, ethereal quality is achieved. Perhaps the area under bridge overpasses might never be dark and inhospitable again. Rather, the bridge would glow and shimmer with the movement of the cars against the sunlight beyond.

Harvesting Water from the Sky

In many places around the world, getting fresh water is not as simple as turning on the faucet. In fact, in rural areas around the world, limited access to fresh water supplies force inhabitants to walk miles to fetch water. This hike not only entails long walks and the carrying of heavy water-laden receptacles, but in many rural developing countries, the groundwater may also be contaminated or in short supply. However, in areas where fog or low-lying cloud cover is frequent enough, there is a low-tech solution that could provide clean drinking water to communities. A recent installation in Venda, South Africa - part of the fog harvesting research project by The University of South Africa, has proven the technology successful by supplying approximately 300 litres of water per day on average to the community of Tshanowa. The system is relatively simple. According to Professor Jana Oliver of UNISA School of Agriculture and Environmental Sciences:

"Each collection system consists of three six-meter-high (twenty feet) wooden poles, mounted nine meters (thirty feet) apart. Steel cables stretch horizontally between the poles and anchor the structure. A double layer of 30 percent shade cloth is then draped over the cables and fixed to the poles on each side. This forms a fog collection screen of about 70 square meters (750 square feet), with a gutter attached to its lower end. The technology behind fog collection is extremely simple, during foggy conditions, the tiny fog particles are blown against the screen and deposited on it. As the drops become larger, they trickle downwards and drop into the gutter. From there, the water is channeled through a filter to a pipe that leads to a water collection tank."

Due to the simplicity of construction and also the technology behind the concept, this seems to be a solution that would work very well in areas with little access to suitable or existing infrastructure.
A similar project by Imke Hoehler called Dropnet also uses the same technology as the UNISA but has redesigned the system to be smaller and more portable. Whereas the UNISA project is a built-in-place installation, the Dropnet can function as a re-deployable system.

Fab Fi, Or How to Make the Internet From Junk

Dubbed Fab-Fi by it's creators at the MIT Media Lab, this rusty contraption is actually a handmade reflector for a wireless internet network in Jalalabad, Afghanistan. While traveling in the region, members of the Bits and Atoms Lab showed locals how to build the reflectors from scraps of metal, wires, and tin cans. Since then, members of the community have built enough reflectors and, in conjunction with wireless routers, have boosted the range of internet connection to many locals who would have no access otherwise with 25 simultaneous live nodes in Jalalabd.
When compared to a similar World Bank funded initiative to install internet infrastructure in the region - which took 7 years and millions of dollars worth of investment to achieve similar results - the idea that teaching concepts is sometimes the best solution. Imported infrastructure is often expensive and highly sophisticated, whereas a piece of technology developed from a concept that uses local materials and methods can evolve into an extremely potent solution. By using materials that already exist at hand, the users are most likely tapping into a material stream that is both local and readily available. As these materials are probably common to their makers, their use and manipulation is that much more of a familiar process. Furthermore, the possession of imported infrastructure is often kept to the supplying entity. With locally created technology, the process can become part of a user-generated economy - something that will do more good for a distressed region than any type of imported technology.

Landscape Condenser

As a proposal for a multi-use building in Yecla, Murcia - a region in Spain known for it's production of grain, wine, oil, and fruit - Andres Jaque Arquitectos has designed a building with distinct sections of green roof, each suited for a different crop. In addition to being an extension of the surrounding landscape, the sectionalized roof-crops offer a precursor to the future of vegetative buildings. Considering that different components of buildings - roof, wall, floor - have specifically constructed variations in size, shape, and orientation, it is easy to associate their form with that of the naturally occurring landscape of a given environment. Where certain species of flora require flat, shallow troughs of land to grow, a flat roof may be suitable. However, if certain species are able to adapt to a steep incline, walls or a pitched roof may be accommodating. The natural variations in building form could also be used to limit or maximize exposure to the elements. Plants that need large quantities of sunlight to grow can be placed with a southernly exposure, whereas more sensitive crops could be shielded from too much light by a carefully placed pitched roof. The topography of a landscape has as much to do with species growth as that of the climate. As designers begin to reproduce and incorporate elements of nature into the built environment, careful consideration of all aspects of locale should be considered.
