Western ideas of how healthcare is deliv- ered are only as relevant as their ability to be suc- cessfully implemented. In areas of cultural or political transition, basic needs like healthcare serve as the building blocks for new communities. Our permanent, scalable and expandable strategies for these facilities reflect the values of cultures and access to natural resources that each context has to offer in Afghanistan and beyond.
  3. 3. 4 5Off the Grid: A Different Direction inBringing Healthcare to Developing Nations As the team was developing the design for the Afghan 100 bed prototype, there ap- T peared to be a specific niche that the project was addressing. A confluence of a particular need, a particular quantity of services, and an architectural solution that is simple, flexible and transferable to many sites. We recognized that the model being he idea is a healthcare prototype that bridges a designed can fill a void in the healthcare fabric of many developing nations; and that if this void is filled, it could bring a leap in the quality of life of thousands at a minimal gap in the society of developing nations. The gap be- investment. So when an ideas competition was announced within the firm, we start- tween rural clinics and urban hospitals.

There have been many architectural competitions about bringing, small, portable, often temporary, chy of security and wealth. It’s not just about access healthcare facilities to underserved populations. This project takes another approach to care; it’s about access to the future, by putting down by proposing a permanent, site-specific building that encourages the participation and investment of the locals. It is not trying to import Western solutions, it is using uni- roots and investing in local, long term growth.

They must be small enough to operate off the grid, yet large enough to achieve an economy of scale in water and power production. We think of these buildings as more than health centers, but rather social centers: places for edu- cation, security, and employment. By providing a hub of infrastructure, the 100 bed hospital becomes a community catalyst, an engine for change.
  4. 4. 6 71.0 World Health IndicatorsThere are literally hundreds of sites in need of permanent, scalable healthcare. Using World health data, we selected four sites including Afghanistan forfurther study. Using indicators including infant mortality, life expectancy and skilled professionals at live births a picture of need begins to evolve. More Newborn life is fragile.than half a million women die every year of complications during pregnancy or childbirth. Most of these deaths can be avoided as the necessary medicalinterventions exist and are well known. The key obstacle is pregnant women’s lack of access to quality care before, during and after childbirth. Investing Almost four million childrenin health systems - especially in training midwives and in making emergency obstetric care available round-the-clock -- is key to reducing maternal mortal-ity.Nearly 10 million children under the age of five die every year - more than 1000 every hour. These children could survive and thrive with access tosimple, affordable interventions. Helping countries to deliver integrated, effective care in a continuum, starting with a healthy pregnancy for the mother,through birth and care up to five years of age is crucial. Investing in health systems is key to delivering this essential care. die every year within a monthWe have identified 3 other case study sites in addition to Afghanistan to further explore the implications of our strategies. of their birth.

  8. 8. 14 151.1 A Scalable Strategy Areas in crisis in need of healthcare resources need to balance the immediate needs of care with the rebuilding of physical com- munities. We believe that the community hospital built to reflect the communities needs through expedient and simple construc- tion can serve as the rebuilding blocks needed. The fundamental planning modules represent a simple and achievable outcome for areas of the world most in need of quality, permanent healthcare. An expandable strategy of building in rural areas accomplishes this.

Services that are highly technical, such as cardiac cath., can be brought to many new patients. Services that are too specialized for wide use, such as lithotripsy and cataract surgery, can be brought to rural areas. The “Hub” clinic provides an interface for the local and international community to interact, via technology and expertise. It is the beginning of new expectations for both the patient and the care industry. A higher expectation, that suffering is no longer acceptable, that medicine is not just for the urban and the wealthy.

While population data is somewhat unreliable for Afghanistan, Pashtuns make up the largest ethnic group at 38-44% of thepopulation, followed by Tajiks (25%), Hazaras (10%), Uzbek (6-8%), Aimaq, Turkmen, Baluch, and other small groups. Dari (Afghan Farsi) and Pashtoare official languages. Tajik and Turkic languages are spoken widely in the north. Smaller groups throughout the country also speak more than 70 otherlanguages and numerous dialects.Afghanistan is an Islamic country. An estimated 80% of the population is Sunni, following the Hanafi school of jurisprudence; the remainder of the pop-ulation--and primarily the Hazara ethnic group--is predominantly Shi’a. Despite attempts during the years of communist rule to secularize Afghan society,Islamic practices pervade all aspects of life. Islamic religious tradition and codes, together with traditional tribal and ethnic practices, have an importantrole in personal conduct and dispute settlement. Afghan society is largely based on kinship groups, which follow traditional customs and religious prac-tices, though somewhat less so in urban areas.

Our goal is to maximize staff coverage, while minimizing the privacy andinfection control issues that wards create. An open 4-patient room, with a bed in each corner, is common in these settings. Our scheme improves uponthis model by using a 6-bed space that is subdivided to act as a 3-patient room. Efficiency is increased in staffing and area, with a layout that is easier toflex at night or with low nursing levels.

  25. 25. 48 491.3 Case Study - Zambia Natural ventilation, solar shading,thermal mass and proper building orientation will provide the most benefit to the inhabitants. Buildings cre- ate the potential not only for health services but to generate clean power through building integrated wind turbines, photovoltaics and a biofuel gen- eration system. Africa is the world’s largest consumer of biomass energy (firewood, agricultural residues, animal wastes, and charcoal), calculated as a percentage of overall energy consumption. African nations have made considerable advances in the use of photovoltaic (PV) power. PV’s are readily available in Africa - in 1998, Sweden and Zambia agreed to a PV rural electrification project. In Kenya, a series of rural electrification and other programs has resulted in the installation of more than 20,000 small-scale PV systems since 1986. These PV systems now play a prominent role in decentralized, sustainable electrification. Shaded courtyards create an environmental buffer zone at the perim- eter walls as well as areas for social interaction and cultural use. Water runoff from the roofs is captured for building use or released into natural filtration areas. Waste from buildings can be effectively recy- cled into biogas through anaerobic bioreactor or digester to create electric- ity and even cooling through cogeneration. Evaporative cooling may also be employed. Approximately 5% of Africa’s power generation comes from geo- thermal sources. There are two major geothermal energy developments currently under development in Zambia. One is the Kapisya Geothermal Project, located in Sumbu on the shores of Lake Tanganyika. Geothermal heat pumps use the Earth’s constant temperatures to heat and cool build- ings. They transfer heat from the ground (or water) into buildings in winter and reverse the process in the summer. Organic Waste Stream - Organic wastes are to be collected on-site and composted for integral urban farming or sale to exterior farming cen- tres. Material Resource Recycling Stream - Relatively benign materials such as paper, cotton, plastics are to be collected, sorted and recycled. Ventures may be established with manufacturing industries to create closed loop resource cycles.
  26. 26. 50 511.3 Case Study - Zambia The Afghan version of the prototype is designed to resist very high siesmic risks. This resulted in smaller opening in exterior walls, which support the roof. In other parts of the World, the high walls of the patient wards could utilize more open area and increased natural ventilation, as shown here. The shaded courtyards act as green- houses to control sun and water expo- sure. Large gardens in these elevated containers supplement food production and reuse site water. These areas are accessed via doors directly off each of the 6 bed patient rooms. The tend- ing of these gardens by family and less acute pateints creates another venue for healthy distraction.

Special clinics and basic Total expenditure on health as % of GDP services are offered to diabetic and hypertensive clients (2006): 5.9 at the primary care facilities. Secondary and specialized care and services are provided at the three general hos- pitals and the psychiatric hospital. Although clients may seek care at any facility, the administration and man- agement of health facilities are based on the catchment population.
  28. 28. 54 551.3 Case Study - St. Lucia Small developing island nations are among the most impacted by cli- mate change because of their vulnerability to extreme weather and rising sea levels. However, because of their small size and low levels of energy use, they have the potential to convert to renewable sources much more easily and can serve as models for other countries. Saint Lucia’s govern- ment is currently seeking to become the first “Sustainable Energy Dem- onstration Country” amongst small island nations in the Caribbean. The country is hoping to diversify its energy market by ending its nearly exclu- sive reliance on diesel generators for production and rely more on its natu- ral setting that is ideal for solar, wind, and geothermal power. The building’s orientation follows the surrounding village’s NE to SW axis to take advantage of prevailing tropical trade winds. Breezes pass over the sloping roofs and are channeled through wind turbines, then continue on to cool the courtyards. Solar hot water panels take advantage of the abundance of sunlight. Photovoltaics could also be used to assist in power generation. Shaded courtyards create an environmental buffer zone at the perim- eter walls as well as areas for social interaction and cultural use. Water runoff from the roofs is captured for building use or released into natural filtration areas. Waste from buildings can be effectively recy- cled into biogas through anaerobic bioreactor or digester to create electric- ity and even cooling through cogeneration. The Eastern Caribbean has significant geothermal potential since most of the islands lie on dormant and active subsurface volcanoes. Saint Lucia alone has approximately 680 MWe of geothermal power poten- tial. Saint Lucia’s island neighbor, Nevis, has begun constructing a large geothermal plant that will provide 10 MW of power, and the Saint Lucian government is attempting to pass legislation funding similar geothermal endeavors. Organic Waste Stream - Organic wastes are to be collected on-site and composted for integral urban farming or sale to exterior farming cen- tres. Material Resource Recycling Stream - Relatively benign materials such as paper, cotton, plastics are to be collected, sorted and recycled. Ventures may be established with manufacturing industries to create closed loop resource cycles.

Its nominal GDP for 2008 was 333.34 billion yuan (48 billion USD). Its per capita GDP of 8,824 RMB (1,270 USD) ranks last in all of the PRC. Life expectancy at birth m/f (years): 72/75 Its natural industry includes timber and forestry. Other important industries in the province include energy Healthy life expectancy at birth m/f (electricity generation) and mining, especially in coal, (years, 2003): 63/65 limestone, arsenic, gypsum, and oil shale. Guizhou’s total output of coal was 118 million tons in 2008, a 7% Probability of dying under five growth from the previous year.[1] (per 1 000 live births): 24 Guizhou adjoins Sichuan Province and Chongqing Mu- nicipality to the north, Yunnan Province to the west, Probability of dying between 15 and Guangxi Province to the south and Hunan Province to 60 years m/f (per 1 000 population): 143/87 the east. Overall Guizhou is a mountainous province however it is more hilly in the west while the eastern Total expenditure on health per capita and southern portions are relatively flat. The western (Intl $, 2006): 342 part of the province forms part of the Yunnan-Guizhou Plateau. Other cities include: Anshun, Kaili, Zunyi, Duyun, Liu- Total expenditure on health as % of GDP panshui and Qingzhen. (2006): 4.5 Guizhou has a subtropical humid climate. There are few seasonal changes. Its annual average temperature is roughly 10 to 20 °C, with January temperatures ranging from 1 to 10°C and July temperatures ranging from 17 to 28 °C.

The taller walls of the wings can face south to maximize daylighting. Roof overhangs and sun- shades further protect the facades from direct solar gain but allow reflect- ed light to enter the rooms. The UN Environmental Program estimates that CO2 levels in Beijing could be reduced by 80% if the city meets its goal of greening 70% of their roofs. Developing areas can be proactive by greening new roofs now rather than retrofitting later. Additionally, as rural farms are lost to urban development, green roofs provide an opportunity for food production. In this application, the roofs could also be used to grow plants for traditional Chinese medicines. Shaded courtyards create an environmental buffer zone at the perim- eter walls as well as areas for social interaction and cultural use. Native plantings can be used to eliminate the need for irrigation. The Guizhou province receives abundant rainfall but lacks the means to provide an efficient and reliable water infrastructure. Managing and reusing stormwater runoff is therefore a key element in the roof and court- yard design. The green roofs slow drainage during heavy rains, and filter the water for reuse in the building. China has been exploring and using geothermal energy for 40 years and its use is currently growing by 10% each year. Uses of geothermal re- sources in China are widespread including domestic heating, tourism spas, and aquiculture. The utilization of a ground source heat pump is a better renewable alternative to photovoltaics given the Guizhou region’s high percentage of overcast days.
