INTRODUCTION TO STUDIO UGANDA The architecture school of the State Academy of Art and Design in Stuttgart, Germany offered the “Studio Uganda” in the summer semester 2019 within the Masters of Arts architecture program. The studio’s task is to develop an architectural design proposal for a training and community center for the St. Gabriel community in Kashenshero, Mitooma District, Uganda Africa. The foci of the studio are on climate responsive design, as well as on the consideration of construction methods taking into account regionally available resources. With this goals in mind the Studio Uganda was collaboratively operated and supported by two architectural chairs of the state academy of arts and design: Unit for building technology and climate responsive design (Prof. Rudolph) as well as the Unit for Structural Design and Technology (Prof. Engelsmann). The semester was divided into the preparation of analysis, formulation and reflection of urban and architectural design strategies, as well as the conception and elaboration of the concrete architectural design project. In addition to the consideration of stake- and shareholders, spatial program and social aspects, the focus of the design is on the integration of sustainable construction methods as a smart response to the local climate and resources. This means in particular the intelligent combination of aspects of the local climate, the availability of materials and craftsmanship competence, as well as the resulting form-finding and construction methods, against the background of later feasibility. This book comprises the final work of the Studio Uganda in regards to analysis, masterplan concept as well as individual architectural design proposals. The design process was organized in the way that students in groups of two to three people collaboratively worked on specific site research themes, summarized in the chapter “Analysis” and masterplans, summarized in four different “Masterplan” chapters. Within these masterplans the students individually or in groups of two further developed their architectural design proposal. The chapter organization in this book follows closely the working process of the studio Uganda. Within the masterplan chapters the associated individual architectural design proposals are presented.

STUDIO UGANDA TEAM The team of the Studio Uganda comprises the following students of the school of architecture of the State Academy of Art and Design Stuttgart: Benjamin Adolphi, Lea Eichelbrönner, Natascha Fakler, Anja Geiger, Laura Lehle, Samia Matar, Heba Mostafa, Ines Schlecker and Lea Wiedemann The studio was organized, led and supported by the following academic team: BUILDING TECHNOLOGY AND CLIMATE RESPONSIVE DESIGN Prof. Dipl.–Ing. Matthias Rudolph, Acad.Assoc. Dipl.–Ing. Christian Degenhardt, B.A. Mohammed Hamza - ( gt.abk-stuttgart.de) STRUCTURAL DESIGN AND TECHNOLOGY Prof. Dr.–Ing. Stephan Engelsmann, Acad. Assoc. M.A. Oliver Kärtkemeyer (ke.abk-stuttgart.de)

COLLABORATION UGANDA MARTYRS UNIVERSITY The studio was operated in close exchange with the Uganda Martyrs University (UMU) in Kampala - Faculty of the Built Environment (Prof. Olweny, TA Ahimbisibwe). The Faculty of the Built Environment offered the same studio task to their architecture students at the Uganda Martyrs University (UMU) in Kampala. In addition the architecture students of UMU shared their local project research supported by an on-site visit in Kashenshero during early spring 2019 with the ABK students to support the development of their off-site basis of design. EL BUENO TECHNOLOGIES Furthermore the close collaboration with the clientâ&#x20AC;&#x2122;s representative, Mr. Derick Kwizera from El Bueno Technologies, a legal Limited Liability Company that deals in project management, architectural auditing, building designing and construction activities based in Kampala, supported the successful development of the studio`s progress in design. Mr. Derick Kwizera visited the studio in Stuttgart for one week at the end of May 2019. This was a great opportunity for feedback and information exchange between the studio Uganda and the clientâ&#x20AC;&#x2122;s representative. UNIVERSITY OF PADERBORN Last but not least the studio would not have been started without the pro-active impulse of Mr. Tobias Klaus, a research assistant in the field of renewable energies at the University of Paderborn. Trained as a political scientist, Tobias Klaus has been working on renewable energies since 2007, and since 2010 has been involved in the development of PV projects, especially in rural electrification in seven African countries (afrisolar e.V., REED). He successfully brought in his expertise into the organization of the studio as well as his practical and technical experience during his supporting visit in Stuttgart for one week at the end of May 2019.

PROJECT SITE & CLIENT The Christian community - Parish Council St. Gabriel - has decided to plan and build a training and community center in Kashenshero. This should not only serve Kashenshero, but also the region as a meeting point and strengthen the local identity and development. Kashenshero is a village developed area in the southwest of Uganda in the border region to the Democratic Republic of Congo and north of Rwanda, approx. 340km away from the capital Kampala. The project area / property is located in Kashenshero, Mitooma District in southwest Uganda. The area is characterized by a rural, mainly agricultural structure. The location of the property is:

0°37'43.8''S 29°59'06.1''E

The plot has an area of approximately 8900 m² and is intended for development by the Catholic "Parish" of Kashenshero. The topographic map of the property shows that the NO-SW oriented terrain slopes SW with a height difference of about 14m. On a length of 180m this results in an average gradient of 7.8%.

PROJECT GOALS Like many other more agricultural areas of Uganda, the younger generation is attracted to nearby or distant cities due to the lack of development prospects in the local region. Within this context, the client, the catholic community of Kashenshero (Parish), wants to strengthen the local development and to prevent a migration of the young population by establishing the new St. Gabriel Entrepreneurship Center. The community comprises approx. 20,000 - 30,000 members in the region within a radius of approximately 25 km. In addition, the new center shall be used as a community center for various workshops, music and cultural events. For larger events, an outdoor area on the site shall be designed to provide space for larger gatherings of people, e.g. larger celebrations such as Christmas, Easter. Excerpt from the analysis of the St. Martyrs University regarding the objectives of the project: FUTURE VISION FOR KASHENSHERO AND MITOOMA In line with Uganda’s National vision of “A transformed Ugandan Society from a Peasant to a Modern and Prosperous country by 2040”, Mitooma District theme is “Strengthening the Community for Sustainable Wealth Creation through Youth and Women Empowerment, Education, Health and Infrastructure Development”. Additionally, Kashenshero Town residents have a goal to become a municipality, have a larger trading center, a new road (which is currently under works) connecting Mitooma district to Rukungiri via Kashenshero. The town vision reads “A prosperous and healthy population readily accessing quality services in a well-planned and environmentally sustained town by 2040”.For the social center The proposed social center is viewed as a place to socialize and have celebrations, that brings the community together. Several Kashenshero residents expressed the importance of holding celebrations as a community and the development that would come of working together. A number of community members expressed the importance and need for the youth to be a large part of the development of the social center and in turn the growth of Mitooma. This is in line with the Mitooma District theme for development as this is an investment on time. It was mentioned that the youth merely required guidance in that regard. The technical skills imparted at this center are projected to economically benefit the community. As the social center will be church owned, activities planned within the area would directly benefit not only the Parish, but also provide self-employment opportunities to town members. Therefore, Parish leaders project that the social center could be financially advantageous to the church as it is dependent on church-goers.

PROGRAM & DESIGN FOCUS PROGRAM The program is based on the information provided by the client and can be adapted to the individual design specific objectives. The design brief comprises the development of an overall concept for the site area, taking into account the objectives of the project, the existing neighboring buildings and the local infrastructure. The development of a masterplan for the entire site is followed by an architectural concept and elaboration of individual buildings with special consideration of the local climate and resources. Since it is planned to implement the concept, special attention shall be paid to the construction method and the local opportunities of implementation. Further objectives are to be discussed and formulated with appropriate concepts. The proposed program listed below serves as a guideline and can be supplemented accordingly.

− − − − − −

Training and production bakery approx. 50-100m² with wood fired stove Bistro ~ 20-30m², in which the products of the bakery are offered Bank with ~ 50m² with small banking room and entrance hall Multipurpose and event space for 150 persons approx. 200-300m² Outdoor meeting place for 5000 people min. 2500 m² for gatherings and festivals Accommodation with ~15 rooms with common room and washroom and extensibility for up to 25 persons

General Considerations / Notes: − − − −

Event space might be separable into smaller areas for workshops Event space might be used as main stage and operable facades to the outdoor mee ting place Outdoor area in general shall be designed with consideration of outdoor comfort / shading / weather protection In the future the plot can be extended up to 100 acres

CLIMATE AND ECOLOGY An essential design factor is the handling of the unique climate situation in Kashenshero and the resulting questions about climate responsive construction. The aim is to design a building ensemble that will become an integral part of the site and its ecosystem by using local resources for construction and operation instead of causing externalized environmental costs. In addition to the efficient use of resources, the aim is to enable as high a proportion as possible of self-sufficiency with energy during operation. Strategies and technologies for handling materials, energy and water cycles should be taken into account in the design. In contrast to Germany, there is no feed-in tariff. Solar power generation, e.g. through photovoltaics, is therefore a key means of self-sufficiency. The use of renewable energies should not be an "add-on" but an integral part of the architectural design. MATERIAL AND CONSTRUCTION The project task comprises the development of an architectural and a structural concept for the supporting structure and building envelope. Materials and construction methods can be freely chosen, but must be related to locally available technologies and materials. The building envelope must be chosen according to the climatic requirements. The development of the design also includes the development of essential structural details and the elaboration of the foundation.

FUTURE AND VISION Samia Matar

For Kashensero and Mitooma In line with Uganda’s National vision of “A transformed Ugandan Society from a Peasant to a Modern and Prosperous country by 2040”, Mitooma District theme is “Strengthening the Community for Sustainable Wealth Creation through Youth and Women Empowerment, Education, Health and Infrastructure Development”. Additionally, Kashenshero Town residents have a goal to become a municipality, have a larger trading centre, a new road (which is currently under works) connecting Mitooma district to Rukungiri via Kashenshero. The town vision reads “A prosperous and healthy population readily accessing quality services in a well planned and environmentally sustained town by 2040”. For the social center The proposed social center is viewed as a place to socialize and have celebrations, that brings the community together.

UGANDA 2040 & THE VISIONS OF YUWERIMUSEVENI

„Uganda Vision 2040 provides development paths and strategies to operationalize Uganda’s Vision statement which is “A Transformed Ugandan Society from a Peasant to a Modern and Prosperous Country within 30 years” as approved by Cabinet in 2007. It aims at transforming Uganda from a predominantly peasant and low income country to a competitive upper middle income country. It builds on the progress that has been made in addressing the strategic bottle-necks that have constrained Uganda’s socio-economic development since independence, including; ideological disorientation, weak private sector, underdeveloped human resources, inadequate infrastructure, small market, lack of industrialization, underdeveloped services sector, underdevelopment of agriculture, and poor democracy, among others. The Vision 2040 is conceptualized around strengthening the fundamentals of the economy to harness the abundant opportunities around the country.The identified opportunities include: oil and gas, tourism, minerals, ICT business, abundant labour force, geographical location and trade, water resources,industrialisation, and agriculture among others that are to date considerably under-exploited. Achieving the transformational goal will thus depend on the country’s capacity to strengthen the fundamentals including: infrastructure (energy, transport, water, oil and gas, and ICT); Science, Technology, Engineering and Innovation (STEI); land use and management; urbanisation; human resource; and peace, security and defence. Projections indicate that Uganda will graduate into a lower middle income country by 2017, progressing to an upper middle income category by 2032 and attaining its target of USD9500 in 2040. Projections further indicate that Uganda will be a first world country in the next fifty years. To achieve this transformation the average real GDP growth rate will have to be consistent at about 8.2 per cent per annum translating into total GDP of about USD 580.5bn with a projected population of 61.3 million in 2040.

S. MATAR

Uganda Vision 2040 identifies key core projects that need to be started including: A Hi-tech ICT city and associated ICT infrastructure; Large irrigation schemes in different parts of the country; Phosphate industry in Tororo; Iron ore industry in Muko, Kabale; Five regional cities ( Gulu, Mbale,Kampala, Mbarara, and Arua) and five strategic cities ( Hoima, Nakasongola, Fortportal, Moroto, and Jinja); Four international airports; A standard gauge railway networkwith high speed trains; Oil Refinery and associated pipeline infrastructure; Multi-lane paved national road net work linking major towns, cities and other strategic locations; Globally competitive skills development centres; Nuclear power and hydro power plants (Ayago, Isimba, Karuma, and Murchison Bay); Science and Technology parks in each regional city; International and national referral hospitals in each regional cities.“ Addional to the Vision of „Uganda 2040“ President Yoweri Kaguta Museveni ( born 1944) is and will be President of Uganda at least untill 2035. Museveni`s Vision of a modern Uganda comparatively to Europe. The population statistics are from UBOS Census 2014, with projected figures up to April 2017, based on district population growth rates published in the Census 2014.

VISION FOR THE DEVEL- There is also an opportunity for the project to be exemplary as a sustainable project in the OPMENT community, with innovative and sustainable ENTREPRENEURSHIP CENTER

The Parish and Community Vision Through interviews with the Parish Priest and community members, it is clear that the establishment of and entrepreneurship center is a welcome development in the Kashenshero community. They wish for the entrepreneurship center to grow into one that will help boost the economy of the community. This is in line with the Mitooma District theme, â&#x20AC;&#x153;Strengthening the Community for Sustainable Wealth Creation through Youth and Women Empowerment, Education, Health and Infrastructure Developmentâ&#x20AC;?. In addition, one of the goals of the Kashenshero Town Council administration and in turn, the residents, is to grow Kashenshero Town Council into a municipality which has a large trading center that attracts residents from neighboring towns. The site location along a major road connecting Rukungiri District to Mitooma and Bushenyi Districts provides the opportunity to attract and engage individuals from neighboring towns and districts.

The farmer hopes for more harvest yield and that the younger generation will have the opportunity to learn more about the business and will get more skills in agriculture. In the next steps, we have considered schoolchildren and graduates. They wish for a future and a good future. On the other hand, they need more activities and the exchange between other young people. In the latter case, we are taking on the older generation and they are more concerned about health care and that they can still make contacts and have their families around them.

Kashenshero and the site are located along the road from Mitoma to Rukungiri and the plot is situated as usual in this area on a hilly landscape. It is near the current Parish center of Kashenshero with church, health center, secondary school and the town council buildings. The land and the potential expansion is arranged around a little valley. Special characteristic of this site are the overgrounded power lines which separate the site from the road. The vegetation is mainly grasland and up the street is a tree avenue. Surroundings: Around Kashenshero, Buildings are mainly developed along the road, what can be explained with life that takes place on the roads. The village of Kashenshero is an acculumaton of houses along the major road, but there are many dispersed houses around along smaller roads that belong to Kashenshero in terms of using schools, church, etc. The church is visited within a radius of ca 25 km. Many houses are build orthogonal to the street with shops on the streetside and private areas behind that. banana plantation

TRANSPORT & MOBILITY Laura Lehle

During the 1970s and early 1980s, the economic crisis and civil strife that affected the country greatly hindered the development and maintenance of urban transport infrastructure. There are approximately 800,000 vehicles in the country, with a potential of additional 20,000 vehicles per year. Over 70% of these vehicles are registered in Kampala City and run the city roads daily.

â&#x20AC;&#x17E;Boda Bodasâ&#x20AC;&#x153;, the motorcycle taxis, are quite common in most towns and trading centres. They are costly and to a great extent risky. According to Police statistics, the National referral hospital causality ward at Mulago receives an average of 5 people per day with injuries caused by Boda boda. In Kashenshero Town Council, we mostly have to deal with boda boda pedestrian traffic. Not to be ignored are the people who walk several kilometers to get to the trading center. Especially the girls and boys cover a long distance to get to school. Relating the St. Gabriel community center in Kashenshero, the development of traffic has to be kept in mind, since the site is located directly next to the road.

Matatu (03)

Dirt road next to the site (on left side) (02)

In Kampala, the capital of Uganda, public transport has largely been neglected by government and has thus not been well managed. 14-seater commuter taxis were introduced mainly to serve Kampala and its environs. Uganda Taxi drivers and Operators Association (UTODA) an association of mainly semi-illiterate persons, manages commuter transport in major towns. UTODA is the dominant organization responsible for collecting and managing commuter transport services.

There are no finances and adequate capacity to build public transportation systems or to expand roads to handle the new traffic. The challenge is how to plan for an increasing importation of second hand vehicles in the city of Kampala which in essence has created high levels of traffic congestion, parking difficulties, difficulties for pedestrians, massive air pollutants and an increase in greenhouse gas emissions.

According to the Ministry of Water and Environment (2017) about 92% of the population of Mitooma have access to safe water (not comparable to European standards - no drinking water ). Most of the people (68,3%) are served by protected natural springs. Shallow wells, deep bore holes and rainwater tanks are serving another 17,2%. Since 2014/2015 Kashenshero Town Council is connected to the national water grid, initiated by the NWSC (National Water and Sewage Corporation), which serves an additional 14,6% by public taps.

In general, Uganda is very rich in energy resources, thus it is absolut procreative. Ugandaâ&#x20AC;&#x2122;s main source of energy is biomass, itÂ´s responsible for 94% of the total energy consumption in the country. Furthermore, hydropower, solar energy, wind energy and geothermal energy, cogeneration and fossil fuels are available. The supply of electricity at national level is very low with 26,7 % in 2018 with only 10% in the rural areas. The energy for electricity mostly consists of hydropower.

In Kashenshero, the main souces of energy are biomass, hydroelectricity and solar energy. Kashenshero TC maintains a power supply line, which passes right through the site of St. Gabriel community center along the dirt road. But it is most likely, that this line is not very reliable. Because of that, a lot of households are using generators and batteries. A few have installed PV panels. Also it is common to use wood for cooking.

How is the village linked to the region / to the rest of the country? In terms of transportation, economy, migration fl ows, infrastructure, etc.? There are three main types of trade in Kashenshero: Markets, where regional products are sold, Shops that sell regional and other products and Door to Door Trade, where are non-regional products sold off. SHOPS

By Doot to Door trade are mainly sold non organic products. This kind of trade is costly because it often requires having a bicycle or a motorscooter. IMPORT AND EXPORT There is an Export between Kashenshero and its neighbourhood towns Kati, Mitooma, Rukungiri and Busheny: Kashenshero mainly exports agricultural products. Leading product are coffe, bananas and eucalyptus timber. Throuthought the whole country of Uganda, the main export product is coffee. Uganda imports mainly technical equipment and petroleum from other countries.

INTRODUCTION The Republic of Uganda is located on the equator and is about the size of the UK. Apart from the dry north, Uganda is a very rich and fertile land with a diverse vegetation and wildlife. It is considered as one of the youngest countries worldwide: 48%> 15 years, 2% <64 years. On average, an Ugandan woman gets 6 children Since the 60s, the Ugandan population has increased about sixfold. It is a multi-ethnic state populated by more than 40 ethnic groups (Bantu peoples 60%, Nile peoples 15%) and goes mostly back to the former kingdom Baganda. Like in the most African countries, Uganda does not that much depend on institutions.The community is very important and so everyone is looking after each other. Most of the time the religious structure holds the community together and means more for the people than the establishment. Culture appears to have an impact on many of their lives. For instance, it is considered a bad omen if a visitor leaves one’s home or shop without nourishment. The Ugandan population attaches importance to social gatherings which may include competitions, music and dance performances, workshops and weddings. Uganda came late in contact with religion that has not grown on African soil: It was not until the 19th century, Islam and Christianity took root. Arab traders and missionaries spread their beliefs with such lasting success that today there is only a small minority of traditional African faith (80% Christian, 12% Moslems). Religious freedom is constitutionally guaranteed in Uganda and inter-religious conflicts are the exception.

Education in Uganda

INTRODUCTION Uganda is one of the poorer countries, with little economic power, an expandable infrastructure, and most of the working population is found in agriculture and rural areas. Especially in rural areas, the illiteracy rate of Uganda is still very high, children often help their parents in the farm work and the visit to the school is partially neglected. The Ministry of Education and Sports is responsible for all education in Uganda. The Uganda Education system follows a four-tier system i.e. 3 years (nursery school), 7 years (primary school), 6 years (secondary school) and 3 to 5 years depending on the duration of the course of University. Bushenyi district has a private university; Kampala International University, in Ishaka town; a technical school and a number of primary and secondary schools (Mazige & Aruho, 2010). 87.6% 86.7% 88.5% 40.8% 37.9% 43.5%

Of these, 30 are found in Kashenshero sub county with 11 particularly located in Kashenshero town council, where the site is situated. Religion is one of the major drivers of education in the area .Schools are situated next to places of worship (churches and mosque). This is helpful in supporting students in the schools and contributing to morally stable people. According to the National Population and Housing Census (2014) the offi cial school going age is 6 to 12 years for primary education, 13 to 18 years for secondary education and 19 to 24 years for tertiary education.

VEGETATION IN UGANDA Natasche Fakler

Kashenshero is located in south west Uganda in MWinston Churchill, the fromer British prime minister named Uganda ‚Pearl of Africa‘. One of the main reasons for this terminology was its staggering landscape and the diversity of species. Uganda is part of the Great Rift Valley, whose Central African Trench marks the western boundary of the country. This tectonic fracture area formed lakes like ‚Lake Edward‘ and volcanic mountains like the Rwenzori Mountains. Because of the sunken mountain peaks in the fog, it is also named ‚Moon Mountains‘. The always in snow covered Margherita Peak is the highest summit of the Mount Stanley and also the tallest mountain in the Rwenzori Mountians. Along this top runs the border to the Democratic Republic of Congo. In the altitude between 3000 and 4000 meters maintain a unique flora characterized by gigantism, the giant growth of plants. Therfore, the mountain area is the target of many expeditions. In eastern Africa Uganda is the most watery country. About a fifth of the country overcast by water. The origin of the Nile is located in Uganda. One of the spring is a drain of the Lake Victoria and flows via the Owen Falls, through Lake Kyoga and over the Murchison Falls into Lake Albert. For over 75 years the usage of water from the Nile was regulated in agreements. Now they need to be renewed. According to experts if it‘s not clearly defined there could be a war about the water usage. The vegetation of Uganda mainly consists of subsistence cropland (43,9% of the surface). In the north-east and between the Lake Victoria and Congo is open grassland (10,5%), the midlands are mostly closed grassland (11%) and in the North, East and a bit between the Lake Victoria and Congo is bushland with 7,7%. Only 0,6% of the land surface is used for settlement. Uganda shelters ten national parks and several nature reserves. The Bwindi Impenetrable National Park in which about half of the remaining world population of mountain gorillas live and the Rwenzori-Mountains-Nationalpark, with its singular landscape, is part of the UNESCO world heritage since 1994. The site is located in the highlands south-west. Here, cultivation is even on the high mountain slopes intensive. The land is covered with scattered patches of thick forest or elephant grass and mvuli trees, providing excellent timber. In the cooler western highlands are a higher proportion forest and long grass, while the south-west is mostly wooded and the vegetation gets shrubby to the north and dry to the north-east. The savannah habitat mainly in the North and East is dominated by grassland dotted with Borassus Palms and woodland with forest patches. The woody vegetation is dominated by acacia-dotted savanna species, Olea and Boscia species. Furthermore the forest savannah mosaic vegetation is scattered throughout the country in areas close to water bodies. The vegetation of forests have a high amounts of evapotranspiration increasing the rainfall around the region. Until the middle of the last century Uganda had good wood reserves, but due to the dictator Idi Amins nearly half of the forests were felled. Since then the forest decreased constantly and if nobody stops the prognosis are that in 40 years Uganda wouldn‘t have any forest any more. The deforestation rate is currently 2% of the still remaining forest areas. In many cases the woody areas need to be used for plantations. Not infrequently, this means the clear-cutting of the few rainforest areas.

FORESTRY NATURE CON- Planning Strategy - the decision to dedicate 20% of the forest SERVATION estate to management as Nature Reserves, The goal of the new forestry policy is “an integrated forest sector that achieves sustainable increases in the economic, social and environmental benefi ts from forests and trees by all the people of Uganda, especially the poor and vulnerable”. Man and Biosphere concept of reserve design envisages the defi nition of discrete management zones, arranged concentrically around a totally protected ‘core’ area, and providing for progressively more intensive use towards the periphery of a reserve. The forestry nature conservation is organized in different objectives: fi rst the forest management objectives (e.g. protect viable populations of all species, wild genetic resource, reservoir of seed material, dispersal agents and ecological services..). Second the buffer zone objectives such as: protect and/ or restore the natural vegetation and ecological attributes of areas immediately adjacent to nature reserves, environmental protection zones will protect the natural vegetation and ecological attributes of hilly and mountainous areas, or recreational use and Eco-tourism development. Last but not the least production zone objectives containing e.g. to provide a maximum sustainable yield of sawn timber, pulpwood and other products from plantations, provide a yield of building poles, fi rewood and other wood and non-wood products for industrial, commercial and/or subsistence use, create areas for environmental monitoring and applied research, as well as provide areas for education and training and so on.

30% as Buffer Zones and 50% as Production Zones. - Important points in the planning strategy are biodiversity considerations, economic considerations, social considerations and management considerations. Design of national network of forest Nature Reserves 1. Identify biologically important sites 2. Combine biological and socio-economic considerations 3. Examine options for a diverse national network of complementary protected areas 4. Select ‘prime’ sites for Nature Reserve establishment 5. Select ‘core’ forest sites for Nature Reserve establishment, based on the occurrence of ‘concentrations’ of species not found elsewhere. 6. Additional ‘core’ forests for nature reserve establishment, based on their contribution to the national protected area systems 7. Based on the list of sites selected, assess the potential for equivalent/alternative sites where nature reserve status seems inappropriate. 8.

NATIONAL PARKS The following National Parks are close to the site: Bwindi Impenetrable National Park The vegetation of Bwindi is tight, with its many shades of green, making it rightfully deserve the title Impenetrable. The impenetrable forest is a tropical and subtropical moist broad leaf forests and is biologically rich and important for the conservation of the afromontane fauna, especially species endemic to the western rift valleyâ&#x20AC;&#x2122;s mountains. The topography is very rugged, with narrow valleys intersected by rivers and steep hills. Furthermore, the park has more than 220 tree species, 1,000 fl owering plant species, and more than 100 fern species including the threatened brown mahogany and Brazzeia longipedicellata. Queen Elizabeth National Park The National Park has a massive variety of habitats including the savanna grassland, beautiful crater lakes, swamps, tropical rain forest. However, it has fi ve levels of vegetation in the different sectors; bushy grassland, Acacia woodland, Lake shore or swamp vegetation and forest grassland. The vegetation is a variety consisting of mostly tightest of small

trees including acacias, Capparis tomentosa and Dichrostachys cinerea and evergreens. The parkâ&#x20AC;&#x2122;s grasslands harbors wildlife, forest grassland harbors primates. Kabatoro gate has a chunky ground cover with dense vegetation dominated by candelabra thorn that makes game viewing a challenge. The open savannah plains are on the western shores of the adjacent stunning Lake George, just near to the area where the Kazinga Channel confl uences with this lake. Fringes of Vossia cuspidata with shrubs such as Aeschynomene have developed at lake shores. Kibale National Park This evergreen rain forest park is located near the Fort Portal in the Western part of Uganda, east of the Rwenzori Mountains. Some endangered timber species of trees include Cordial millennia, Entandrophragma Angolans, and Lovoa swynnertonnii. The forest understory is dominated by shade-tolerant shrubs and herbs, which include Palisota schweinfurthii and Pollia condensata, in addition to ferns and broad leaf grasses.

GENERAL Heba Mostafa

Kashenshero has a tropical climate. It is located at -0.6288 latitude and 29.9851 longitude and altitude at 1500m NN. The climate is all year round constant with an annual average temperature about 20,5°C. Analyzing the weather data from the weather station in Mbarra (around 85 km far from Kashenshero; altitude 1422m) it can be said that the the summers are short and warm; the winters are short, comfortable, and wet; and it is overcast year round. Over the course of the year, the temperature typically varies from 15°C to 28°C and is rarely below 13°C or above 31°C. The temperature difference between day and night is about 10°C. Because Mbarara experiences signifi cant seasonal variation in monthly rainfall, the weather can be categorized in three seasons: a rainy season from March to May and from September to December, a dry season from June to August and a transitional period from December to February. The annual precipitation is about 981mm. The most rain falls during the 31 days centered around April 16, with an average total accumulation of 104 millimeters. Compared to Stuttgart it rains twice more time in Mbarara. In the dry season the chance of precipitation is around 20-50mm. The least rain falls around June 30, with an average total accumulation of 17 millimeters.

SUN PATH

The equator crosses through Kashenshero very close, which makes the sunlight shine the same way from above every day, and the temperature stable during the year. The length of the day does not vary substantially over the course of the year, staying within 9 minutes of 12 hours; with the shortest day falling in mid June and the longest in late December. Hence the sun elevation is high. The sun elevation on 21. December is 67° with an Azimuth of 178° and is inclined to the south. On 21. June the sun elevation is 66° with an Azimuth of 1.6° and is inclined to the north. The sun elevation on 21. March is 88° with an Azimuth of 45,5°. Hence the day length is constant with approx. 12 hours. The shortest day is on 31. March with 12 hours and 6 minutes of daylight. The longest day is the 1.

About 6086h (total 8760h) in the year the absolute point, as it determines whether perspiration humidity is between 6.6 and 16.5 g/kg. will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. During the rainy season humidity is mostly high, while in the dry season it is more comfortable. Hence the relative humidity is all year round between 55-95 % and mostly high. About 6084h (total 8760h) in the year the relative humidity is between 26 - 100%. As shown in the psychometric chart the humidity ratio is above the comfort zone, therefore there is a need of dehumidifi cation. This can be achieved by natural ventilation or increasing the air movement by e.g. ventilators in the indoor spaces. Based on the absolute humidity the comfort level is characterized at 12g/kg.

PASSIVE DESIGN STRATEGIES

Ragarding to the passive design strategies the most important aspects that should be considered are the orientation, horizontal insolation, daylight, ventilation, shading and thermal mass. By using thermal mass materials the temperature cycle between day and night could be shifted, because there is a temperature difference about 10Â°C. As the horizontal insolation is very high, shading strategies and ventilation for the roof should be considered. To achieve comfort in the indoor and outdoor spaces the orientation of the buildings is important referring to the wind direction. As the east and west facades are all year round exposed to the sun, the smaller building areas should be in East-West direction. Temperatures between 11 - 20Â°C is from all directions.

LOCAL CRAFTSMANSHIP

The local craftsmanship includes several different crafts, including:

• weaving reeds and fiber • pottery • brush-making • kilns: producing bricks (burned and air dried) in nearby towns

WEAVING

Weaving materials are papyrus reed, bamboo and especially eucalyptus offcuts. With this, they weave eucalyptus mats called „Ekirago“, which find wide usage as floor mats, room separation or as counter-top-covering.

POTTERY

The pottery in nearby towns produces fired clay pots and fired clay charcoal stoves, which are then sold by retail traders within Kashenshero trading center. Local kilns are mostly small and informal and often run by self-employed people. PROFESSIONAL BUILDERS

The majority of skilled builders receive building and construction training from Kabira Technical Institute in Ruhinda County, about 12 km from Kashenshero Trading Centre.

ROOFING

STRUCTURE

There is basically two types of structures available: 1. brick-built walls combined with a wooden structure for the roof, which is holding corrugated steel sheets for the roofi ng. 2. Wooden beams and bars are used to built the whole structure for the walls and the roof. The cladding for the walls is then made out of corrugated steel sheets or wooden planks. The roofi ng is almost all the time corrugated steel sheets as well. Concrete is basically only used for certain columns and special girders, on which brickbuild walls continue. WALLS

Most walls are built with some sort of brick, usually kiln-fi red clay bricks (for more information see the list of building materials). They are usually not plastered. Only in rural regions you can fi nd walls made

Roofs are almost all the time made with a wooden support structure and corrugated steel sheets for cladding. The use of reed and thatch does not seem to be much appreciated any more, probably because it needs much more maintenance. Using tiles for roofi ng is possible, but seems to be seldom so far. FLOORING

fl oors are usually not paved but covered with woven papyrus mats (Ekirago). OPENINGS

houses often only have simple openings as windows, sometimes with metal-grills to protect from unlawful entry. Sometimes they have glazing and often they are equipped with wooden window shutters.

Due to the climatic conditions in Uganda, in Kashenshero life takes place especially on the street. The aim of the design is to create large shaded space between inside and outside. The extensive room program is categorized into 3 types. S M L, which differ in their size and room quality. Any function will fi nd its place in one of the three types. Reduction of buildings allows a high fl exibility, adaptability and re-usability. Type S is designed to allow a sale. This can be from one fruit stand to reach a bank. Type M includes education and training centers such as a joinery or classroom. Type L is a meeting place at which events and meetings can take place. The typological approach allows the village to expand its educational center and assign it with the desired function. Only regional materials are used to guarantee independent extension. The construction consists of local wood, the lamellae of the facade is made out of a traditional wickerwork. So is both a very day-time shuttering as well ventilation guaranteed.

MASTERPLAN CONCEPT

for educational purposes. It is linked by a road to the school in the north, over which also delivery can take place.

The master plan is a well thought out structure of buildings of different typologies. They are arranged in a way that the diverse actions mutually support each other without disturbing actions at same time. ZONING

The property is zoned. In the area at the crossroads buildings of type S are placed. There, the everyday market takes place. The path along the shops leads to the center of the property, where a green location invites you to linger. Adjacent to this is the assembly SITEPLAN hall, the type L. By this one reaches the street in the south. The classroom buildings (type M) are set back in the west. There is a quiet zone

117

VEGETATION

The buildings are loosely arranged on the property to integrate the existing vegetation. Green areas and trees serve as shading and cooling buffer zone. BUILDING CONCEPT

All buildings follow a superordinate concept, which emerges from the main requirements of sun protection, weather protection and privacy. There is a cover - core system that divides each building into different zones. The deeper you go into the building, the more protected you are.

TYPOLOGIES

The given space program includes many different functions: meeting hall, square, workshops, shops, bank, classroom, retail and accommodation. SORTING

The individual functions have requirements that overlap. For example, the requirements of a store and a bank are similar. Even the requirements of a workshop are comparable to those of a classroom. They can be grouped to create three typologies.

BISTRO / KIOSK

TRAINING/ WORKSHOP AREA

CRAFTS RETAIL

FURTHER EDUCATION/ LECTURE

TOWN COUNCIL MEETING

The three typologies differ mainly in their size but also in design (plan layout, choice of material and zoning). Type S is designed to be, for example, a bistro / kiosk, bank or crafts retail. Type M meets the requirements of a training / workshop area, further education place and town council meeting. The large gathering hall is type L, where a variety of events can take place. FUTURE

The typological approach allows fl exible growth of the community center.

ECOLOGY

CYCLE

The aim is to foster the local economy by taking the resources and knowledge that is locally available to draw and use. Local building materials play a big role as well as almost lost construction techniques. MANPOWER

The population of Kashenshero should be involved in the planning and construction process right from the start. The participation of the villagers gives the project an important identity, which is absolutely necessary for success. The Community Center is meant to be a growing project that thrives on change and adaptation. The local people are trained to be able to adopt the building concept and apply it independently.

121

The individual institutions on the property should play each other and promote each other. For example, the fruit can be used on the plantations of the agricultural school in the bakery. These products are in turn sold in the shops. The apprentices in the joinery are to participate in the expansion of the building. ENERGY AND WATER

The region is connected to both public water and electricity. The supply, however, is relatively unreliable and must be supported by local measures. A cistern is to be built on the property to catch the water in the rainy season. This can be used either fi ltered as process water or unfi ltered for irrigation. The power supply is supported by PV systems.

BUILDING MATERIAL

It is mainly clay and wood are used, that is available on the property or in the immediate vicinity. Even traditional crafts, which are only limited to products till now should fi nd their way into the architecture. These include the local braiding techniques with papyrus, from ECONOMY which mats and baskets are currently made.

MARKET SITUATION

TYPE S

123

Lea EichelbrĂśnner

The first type of the series is type S. This can be used for a bistro or small bank office or a kiosk or retail store. It should offer space for 1 to 3 people inside and opens up to the outside to connect to the street life. The smallest buildings are located in front of the site to invite people from the street and lead them further into the community center. Through different usage in type S the floor-plan as well as the openings vary. A retail store should offer space for a salesman and room for storage. Other than that a small bank office should hold space for a consulting room and a waiting area as well as space for an ATM. For a market stall it should be possible to use the outside space since buying fruit and vegetables is a daily need and should be accessible from the street. The buildings are simple, flexible and can adapt to use depending on need. Furthermore the retail buildings can be extened when needed. The most important requirement for Type S is shading from the sun as well as protection from rain. It should be possible to lock the storage room.

In close connection to the workshops from Type M it is possible to sell locally made products like baked goods from the bakery for example. If there is a workshop for crafts that are made by the people working there those also could be sold in a retail store from Type S.

SHAPE

ZONING

The start for creating the shape was the basic form of a square. Two sides are cut of to create two opening sides to the front. Due to the climate conditions the west facade must be kept small. The big facade orientated to the south-west offers ideal space for the wind to ventilate the building.

The building itself is separated into 3 zones. There is the outside area which is potentially roofed. Then there is the indoor space and at last there is the storage core. The different zones offer different qualities of stay.

BUILDING ENVELOPE The facade is not a classic building envelope. In stead of closing the building, it creates a smooth transition between the exterior and the buffer zone. The facade is the identity of the building. It determines both the comfort in the interior and the appearance of the building. WEBBING

OPENINGS

131

There are different types of openings for the different usage options. The example of the bakery retail shows an options where you can slide the woven element up and create a roof overhang to protect from sun and rain. The opening offers the opportunity to sell from the inside to the outside. Other than that there are openings for a door where you rotate the opening element to open it up like a door. It creates the entrance into the building.

The woven frames are The more direct sunlight is directed at one side of the building, the more closed it will be. In the east and west, the elements are very dense and allow diffuse light into the interior. Areas with lower DETAIL irradiation are provided with a more open structure. On the north and south facades the webbing is very light. The wind coming from south-west direction can easily pass through. Fortunately, the two factors of minimum radiation and maximum ventilation can be complied very well.

The second type M is slightly larger than type S. It deals with the topic of education. In Uganda, many young people are moving to the city. They hope to find better opportunities to earn money. Unfortunately they have to leave their families and rarely find acceptable work. To counteract this phenomenon, the community wants a skill center. With the skills learned, people can become selfemployed and find well payed work. In the skill center the offer ranges from from a bakery to a carpentry up to some classrooms for business and agriculture classes. The Workshop buildings are simple, flexible and can adapt to use. Like this, the community can change or envelope their skill program over time. In Uganda life takes place on the street. That is why all workshops are connected to the outside. Furthermore the workspace can be extended when needed. The buildings try to form a space between inside and outside, protected from sun and rain, they can be used all day.

The constructive principle of all types is similar, but is redefined due to the varying span widths. The workshops buildings require beams of 8 m in length, which are still available locally.

The arrangement of the buildings creates different court situations. Some of them are connected and form communication areas. So the exchange between the trades is possible. Other courts are more private and can be used as extended workspace. The whole area is planted with trees to generate a shaded space.

The third type of series is Type L. A meeting hall with a variety of specifications was required. It should be able to accommodate groups of 15 to 500 people. The usage period varies a lot. In everyday life, rooms for choir and dance rehearsals should be available. At the same time the place should fulfill the quality of stay of a village center, where the inhabitants can meet informally. On public holidays large-scale events of the parish are to take place there, to which up to 500 persons from the surrounding villages arrive. Also for private parties and weddings to be created space that can be rented by the villagers. In order to fulfill the requirements, the most rudimentary conditions are investigated: the most important is the protection against sun and rain. In principle, a large roof would already meet these needs. A zoning of the covered area gives the opportunity to better meet the requirements of the different events. As with the other two typologies, the cover - core system is used. The cover protects against sun and rain. It is accessible to the residents at all times and forms the buffer zone between inside and outside. The two cores are the protected indoor spaces.

ARCHITECTURAL CONCEPT

The hull area serves as a sheltered outdoor space that can be used for the daily meeting of villagers, as a stage for performances or as an extension area. The inner cores are the more protected areas. The larger core is a multi-functional room. There can be readings, PROCESS choir rehearsals, courses, small concerts. In the smaller core is a kitchen located. There, catering can be prepared for major events such as a wedding. In everyday life it can be used as a bar where drinks can be consumed during a football broadcast.

The idea is a big roofed zone to protect the people from sun and rain. The assembly hall is a place between inside and outside, because life in Uganda, in Kashenshero takes place outdoors.

INTRODUCTION The new St. Gabriels community center in Kashenshero, Uganda, is constructed like a market square, where the people of the community come together and meet for several reasons. It is a place, where new skills and information are exchanged and educated to support the growth of Ugandas economy in a long term. New opportunities are opened up considering studying, research and how to do business. Combined with the skill center, the market square is a social meeting point, where leisure time can be spent. The car and boda boda-free zone allows networking in a quiet place, framed of the surrounding buildings with the large connecting timber roof. The intermediate spaces between the buildings invite to interact in between and support the high signifi cance of being outdoors for working, chatting or just pausing. All in all, the market square of Kashenshero is a project, which strengthens the identity of the community, animates to participate and the care for each other.

MASTERPLAN

MASTERPLAN CONCEPT In Kashenshero, the site forms the center of the village. The site is close to the church and the bustling commercial center. A secondary school is next to the street, the school is designed as a conversion and forms a courtyard. The surrounding buildings have a typical structure in which the houses are distributed over a large area. The agricultural community is growing in population density, which is refl ected in the core of Kashenshero and the denser development. In the planned property, the existing house structures are absorbed and thought further. The property is located on a trade route which will be expanded by 2040 according to "Uganda vision 2040". The road should connect Mitooma and Rukungiri to provide better transportation routes and improve infrastructure for the people of Kashenshero and the district and beyond. The property is also located at a central hub and in the vicinity there are public buildings.

The knowledge for agriculture should continue to be trained and optimized. The aim of the agriculture-concept is to cultivate new plants, such as bamboo, to gain a better understanding of how to process and optimize the economy. In the Masterplan, the buildings are arranged as the typical development in Uganda. They are oriented to the street and form a courtyard that acts as a market-square. The big roof protects all the boxes and close almost the courtyard. An association with the perimeter block development. The big roof as the magnifi cent element and the boxes as less important are the result of the design concept, as a structure in a less-built-up area. The outcome was the understanding of living together, the culture and the climate- and its effects.

SPACE PROGRAM

The space program is a variety of everyday needs and considerations of activating the place to support education, opportunities and visions. In an agriculturally infl uenced space and places are needed for experimenting and researching. For this purpose, new workshops are to be created. A new common kitchen as meeting area and learning place. The focus is always on the coming together and gather. Furthermore, kiosks will be available for the necessities and a small pharmacy, an Internet cafĂŠ for international exchange and research. An entrance zone designed as a pavilion with generous sheltered roof. In the pavilion, the residents of Kashenshero get attracted at the fi rst station at the water kiosk and are supplied. This water kiosk is self-suffi cient by the water cycle and offers work. The inhabitants are activated and entertained by several stations. There is an event hall and next to it a sports bar. In addition, there is a bank that provides a degree of independence and a library for acquiring skills and a retreat for students.

The property is zoned into an entrance, an exit and a connection to the outdoor event area. The entrance is at the head of the property and on the street. In addition, at this point is a junction of the streets and pulls people into the market-square. Having arrived at the center, the exit is found towards the terrain to the road at the physical end. In the space between event hall and sports bar, a path is zoned wide and connects the open event place. EXTENSION POSSIBILITIES

The extension of the development is divided into several phases. In the fi rst phase a part of the roof complex will be built and then the second part. The buildings below can be built in the next phases. Box for box. This system can be used indefi nitely and can be connected to the new building complex. In another situation, the concept / system can be more variable and be thought of being double and divided or added in small or large structures.

In the Area, a lot of eucalyptus Wood is available, which will be used and other stronger wood from the area. It is mainly dry clay and wood. For the construction of the roof are no metal connection planned to provide high costs. So the traditional wood crafts from Germany can be re-cultivated in Uganda. The collaboration of the traditional techniques with wood and the knowledge of environment and nature creates the aim of this project.

INTRODUCTION The newly planned Community Center should create identity and strengthen the sense of community. A center that will also work in 20 years . It is designed to integrate all cultures, tribes and religions and participate every family, old man and graduate and every farmer. In the Community Center should also provide education. There are different strategies. The education and the know-how are promoted in different areas. For example, in the library, Internet cafĂŠ or the experimental garden. The community center is a central place for participation, education and production. Through the space program and the complexity of construction and the understanding of living together in a community, these attributes are fueled to a result.

ARCHITECTURAL CONCEPT The design deals with the topics of living outside and inside. The emphasis was on the elaboration of a likeness of these two life forms and simultaneously with their hierarchy. Through the master plan, the buildings were set and oriented by the climatic analysis. In the center of the plot is the marketplace, which creates a space that can take the speed of the street and life can take place. A place for everyday life. The wind fl ows through the spaces and through the marketplace. The common roof over the building allows shadowed whereabouts. The roof and the building is designed in a way that it follows the topography and the building is embedded in the slope. The different levels are used for the route guidance. Ramps open up the space and enable a high quality of stay. The pavilion serves as the entrance gate and the event hall as the physical end. The roof is placed that the boxes can be pushed under it in a grid of 6x 1m.

This creates an equality between Intermediate-space and closed space. The ridges of the roof are each above the intermediate space to ensure more quality of stay. The boxes are the only closed elements and in the background. The boxes sit on plateaus and are connected by ramps on the square or over steps. The boxes open to each other and interact with each other. The focus is on the effective community and the strengthen the idea of a community beyond the district. At the Market-square People are learning, eating and living together.

CLIMATE DESIGN CONCEPT

The orientation is along in north-south direction. Open ends of the roof allow constant ventilation. The intermediate spaces are not completely ventilated. In this case, an adaptation of the architectural concept was inserted in the roof openings. The roof shape favors ventilation by following the topography (wind rises and enters the next building). The roof structure, which makes the climate in the space as well as in the building itself comfortable. The warm air of the close areas rises through permeable ceiling (eucalyptus boards) and gets out. The high ridge over the intermediate space gathers the warm air and by design a height, is a greater range of air stratifi cation possible. The metal layer allows a good low E value. The metal stores the heat and gives it only over conduction (low heat radiation). The clay wall with its thermal mass is supportive (saves the heat during the day and returns it at night when the room is not used). The wide overhangs by the self-suffi cient roof provides a good shading of the facade and the intermediate space.

INTRODUCTION Regarding to the climate analysis the most important aspects that should be considered are the orientation, the horizontal insolation, the ventilation and the shading. To protect the buildings from the exposed sun on the east and west facades the buildings are orientated south north but rotated a bit to be ventilated better from the south-west prevailing winds. To strengthen the community and provide education and production areas the masterplan is divided into three areas: the town square, the workshop and production courtyards and the event-space. The idea is to create an interaction between all areas and to connect them all together.

MASTERPLAN

MASTERPLAN CONCEPT The training and community center for the St. Gabriel community in Kashenshero is intended to serve as a meeting point and place to strengthen local identity and development. The education and the community should be strengthened through various uses such as workshops, production and teaching facilities and cultural events. In order to enable interaction between all areas, the urban design is divided into three areas: the village and market square with the shops, bank, bistro and bakery, the workshop and production area and the event and gathering hall. In the northern part of the site the village and market square, acts as a contact and meeting point. Due to its good accessibility and the direct access by the street, the daily activities can take place here. The shops with approx. 20mÂ˛ of fl oor space should enable interaction between all zones through their arrangement and size and attract the inhabitants and visitors to explore the further uses on the site. The workshop and production area is located on the middle level of the site.

Due to the close arrangement and the shifting of several parts of the building, inter-spaces and small courtyards are formed here. This provides direct exchange between the workshop areas and creates spatial connections to strengthen the interaction. The shifted parts of the building also provide mutual shading between the buildings. The workshop areas are divided into three zones: the indoor space, for concentrated work, the roofed inter-space, for the pathways, and the outdoor space for direct interaction and communication. The roofed pathway creates a direct access from the town square, through the workshop area and down to the event hall, hence creating a new street on the site that connects all areas together and provides good access between the zones. The site declines to the south, therefore the three areas are at different levels and enable visual connections from the town square. The buildings are orientated southwest in wind direction to achieve natural ventilation.

CLIMATE CONSIDERATIONS

193

SUN PATH

WIND

The equator crosses through Kashenshero very close, which makes the sunlight shine the same way from above every day, and the temperature stable during the year. Therefore the buildings should be shaded well. The length of the day does not vary substantially. Regarding to the sun altitude and the wind direction the buildings are orientated to south-west. As the buildings are shifted they can shade each other and also create partially shaded courtyards. As the sun elevation is very high at 11 am the horizontal surfaces should be covered to protect from the direct solar insolation. In December the sun is inclined to the south as the building parts facing south should be protected in that period. In June the sun is inclined to the north so the south parts of the buildings are shaded. As the solar insolation is high on the horizontal there is an opportunity to harness solar energy.

Regarding to the site in Kashenshero the main wind direction is characterized from south - west depending on the local topography of the site. Hence the wind direction is stable it offers an opportunity to use the wind for natural cooling. By rotating the buildings about 50Â° to face the wind direction, they can be all ventilated as they are also on different levels. Good ventilated indoor spaces are important because the humidity is very high.

The aim is to use the local resources from the site and take advantage from the high solar insolation and the heavy rains. RAINWATER

The idea is to use the rain water for the sanitary and cleaning. The rainwater is collected by the roofs and subsequently fi ltrated to remove the sand and dirt from it. The water is collected in underground tanks and can be used for the sanitary and cleaning. The plants can be irrigated by a waste water treatment system. The water is purifi ed in a two step process before being released into the nature again. The purifi ed water can be used than to irrigate the plants or to fuel the fi sh pond.

The site is connected directly from north to the street. Therefore there is a direct connection between the town square and the street, where people can meet and the everyday life takes place. As there are roofed pathways in the workshop area they create a direct access from the town square, through the workshop area and down to the event hall, hence creating a new street on the site that connects all areas together and provides good access between the zones. The workshop area is higher than the street level so there is just a visual connection between the street and the workshops to keep them protected from the street.

The aim of the workshop areas are to strengthen local identity and the development of Kashenshero. The production and skills center should provide education and working opportunities for the community. Therefore the workshop area offers different uses as learning and lecture areas, weaving, carpentry and tailoring spaces to strengthen the local identity of Kashenshero by learning, producing and selling at the same place. Thus the community can learn from each other and improve their skills over time. As the daily life in Uganda takes place outside, the workshop area provides different spaces between inside and outside. The closed indoor spaces are for the concentrated work, the shaded inter-spaces connects the areas together and allows the communication between the areas. By shifting the building parts shaded outdoor spaces are created to allow the direct communication, collaboration and exchange between all areas of the workshop space and create spatial relations. Open, semi-open and closed areas are created.

STRUCTURE & MATERIALS

MATERIALS

The idea for the vaulted roof comes from the traditional roman architecture and from the traditional round houses in Uganda. As the vaulted roof is a good climate strategy for warm areas and provides well ventilated space and is traditionally build with brick. Brick has a high thermal mass and shift the temperature cycle between day and night and is and advantage for Kashenshero as there is a temperature difference about 10Â°C. STRUCTURE

The building has a platform the protect the building from the heavy rain periods. The walls are made out of brick and the doors are movable and made out of bamboo and can be open completely to connect the indoor with the outdoor. The lamellae windows are also made out of bamboo and can be open depending on the sun elevation. The brick vaults lie on reinforced concrete beams.

In order to build in a sustainable way and in accordance with the location the workshop should be made out of Hydraulic compressed earth blocks. This bricks are non-fi red and are produced using the clay soil from the site to reduce production costs and protect the environment. Hydraulic Compressed Earth Blocks are nonfi red bricks, produced out of a mixture of soil, clay, sand and water. They also contain less than 5 % cement to make them more resistant against water. The clay content needs to be between 15 and 30 %. The mixture, with a moisture content of approximately 10 %, is hydraulic pressed from two sides. They need to be cured for minimum two weeks while they are covered to maintain high humidity and temperature. So the bricks can withstand the climate of both hot sunlight and heavy rainfall and create a cooler interior climate, too. The idea is to use the bricks for the fl oor, walls and roof the integrate the building into the environment.

ROOF STRUCTURE As the solar insolation on the horizontal surface and the rainfall are very strong in Kashenshero, the idea is to protect the vaulted roof with a membrane structure. The membrane is a lightweight structure and can be introduced as a new roof structure in Kashenshero. By combining the traditional brick vault structure with a modern membrane structure a new architecture is created. It can be a low tech or high tech membrane structure depending on the skills and fi nancial means. The advantages of a membrane are that it has a low wight, can be assemble easily, has a short construction period and is translucent. There are membranes (e.g PVDF) which has a high light transmission, are UV-resistant, dirt- and water-repellent and do not absorb moisture.

Such membranes could be used as roof structure to protect from the high solar insolation and the heavy rains. And it also offers more roofed outdoor spaces for the workshop. The simulation on the facade also proves that there is about 500kWh/m2 less radiation on the facade by covering the building with a roof.

BREATHING COMMUNITY WORKSHOPS Benjamin Adolphi

INTRODUCTION Supporting and promoting knowledge exchange is the main goal in these community workshops. Generating a space which is set back from the public to generate a community feeling but still open enough and accessible for interested individuals was therefore necessary. The buildings are functionally and climatically optimized, considering a large variety in usage and providing large shaded outside space and enhancing natural ventilation. Long known technologies and local materials are the basis for the introduction of three new building technologies. The design uses a repetitive and expandable structure for a simple building process which can act as a model or even generate a new building standard. Accommodation space allows guests to stay on site for several days to receive training in different crafts and technologies.

The roofs shape is generated through people to walk from the public area to the multi-purpose hall and experience the crafts- the special support structure system called "Zollinger-System". The roof is extended in manship when walking on the workshop direction of the courtyards to generate large courtyards without having to enter private sheltered terraces in front of the workshops. workshop space. COURTYARDS

3 ZONES

Widely functional and adaptable workshop spaces are housed in two building rows. In-between spacious courtyards are placed, generating shared outside space for the craftsmen community, The whole complex follows the given topography but levels the terrain in the areas needed, especially in the courtyards. These courtyards generate meeting space for the workshop community, give access to the workshops for delivery, and allow to extend the workspace for special work-steps, that need extension over the regular workshop space. To connect the workshops as much as possible to the courtyards, they are open-able to the courtyards on both sides.

Each Workshop has two large dedicated outside terraces to each side of the workshop. The one in front is only separated by a small platform from the courtyard ground and therefore considered more public. The other on the backside has a larger difference in height to the lower courtyards and is therefore considered as the more private outside space for the craftsmen. The inside space of the workshops is kept rather small, since it is mostly used for storage of material and tools. The craftsmen are mainly working in front of their workshops, where they can work sheltered from sun and rain. This also allows the craftsmen to see, what others are doing, which promotes knowledge exchange.

SPACING BETWEEN BUILDINGS The space between the buildings is 3x the height of the first building, this enables the wind to fully come back to ground level, after being elevated by the first building. This is crucial for a good ventilation of the second building!

CLIMATE DESIGN CONCEPT Since the overall climate in Kashenshero is very decent with temperatures between 15 to 30Â°C, the main challenges for the buildings concerning climate are enabling a good ventilation of the buildings, protecting people from the strong, almost vertical sun during noon and thinking of solutions for potentially strong monsoon rain. ORIENTATION TO THE WIND

The workshop buildings are oriented to the main wind direction. Most of the time wind comes from the valley, rising upwards the site from south-west direction. With this in mind, the buildings rooms were opened up as much as possible in south-west and north-east direction. This is done by the use of a porous facade structure with woven reeds. With this, a constant fl ow of fresh air, coming from the shaded outside spaces can enter the rooms. The roofs pediment areas are oriented in the same direction, to maximize the air exchange and to fl ash off warm air collected under the roof. The distance between the two workshop buildings is three times the height of the fi rst building, which makes sure, that air fl owing over the fi rst roof can reach ground level fully, before being blown up again by the next building. With this, we can maximize the air exchange in the courtyards and make sure, that the second row is fully ventilated without compromise. Topography also helps here with putting the second row of buildings higher than the fi rst row.

BLOCKING OUT STRONG RADIATION

Strong radiation coming from the sun is a topic, which mainly is of infl uence by the decision of form and materials for the roof. Large roof overhangs to both sides of the workshops guarantee shaded and protected space in front of the workshops on every day of the year. Dedicated sheltered spaces on both sides are necessary, since the sun comes from south as well as from north, depending on the time of the year. Material-wise, wooden shingles are used for the fi rst layer of the roof, which with its three layers provide a good insulation and heat protection, especially compared to metal sheets. Underneath the wooden shingles, a layer of metal sheets blocks almost any radiation coming from the sun, before they can continue too the room ceiling or to the roofed outside space. Air doesn't heat up under the roof, since most of the heat gain is already blocked by the wooden shingles. A light structure out of bamboo and eucalyptus mats is used as a room ceiling. This protects from to much wind pressing the warm air back inside the rooms, while still allowing warm air to pass through easily. The walls of the dormitory area are much more enclosed and made out of rammed earth, to make use of the effects of thermal mass. This not only prevents overheating during the day, but can help to generate a more comfortable climate during the night, since people would feel to cold with outside temperatures.

THERMAL MASS Thick walls with high thermal mass are used on all sides for accomodation and dorms and on two sides in the workshop space. This not only prevents overheating during the day, but can help to generate a more comfortable climate during the night, since people would feel to cold with outside temperatures.

RAINWATER SYSTEM

Since Kashenshero has a very limited freshwater system and no sewage system, the collection, use and treatment of rainwater is a important part of the project with high educational potential. Water is collected by the large roof area, fi ltered and then used for different purposes, such as showering, washing of fl ushing of toilets, before treated in a two way process. The treatment process of the water is shown in the diagram on the left page. The water leaving the treatment is then safe to feed back into nature or can be used for watering plants or a fi sh farm.

Various simulations proof, that the design works as intended. A shading simulation shows, that shaded space in front of the workshops is available all year round, even when the sun is low at least on one side. A radiation simulation (see last page) shows, that the radiation coming from the sun is 80% reduced in front of the workshops. A viewfrom-sun simulation shows the times when sunlight is shining on the buildings walls. After 10am until almost 5pm almost no sunlight is impacting on room-enclosing walls.

exploded view of the buildings strucural system

Why Zollinger system? Its a very simple structure, basically only made out of the repetition of two parts (see blue and red colored parts below). One rather thin wooden plank, a lamella, is the basis of the system. Only the tapering on the end of the lamella differentiates the two lamella types, each for one direction in the structural system.

B. ADOLPHI

The advantages of the Zollinger system: Large span widths are possible with small and short wooden parts. 40% less amount of wood is needed compared to traditional roof trusses. A much greater part of the wood of a tree can be used, since the single parts don't need to be long. The wood species can be less load-bearing than the typical construction wood

mats. This perforated ceiling allows warm air rising from the rooms to pass through easily. The vertical grid is also made out of bamboo. Its main function is to slow down wind speed under the roof, while sill enabling consistent air change under the roof

ROOF

The roofi ng is a two layer design, consisting of wooden shingles on top and metal sheets underneath. The metal sheets main use is for blocking the radiation coming from the roof before entering the shaded space. Both materials allow for a light roof, which allows smaller sizing of the wooden structure. A pitch of the roof of at least 22Â°at any point guarantees a long life of the shingles.

WALLS

The roof structure is designed in the same grid as the layout of the building, which allows that most walls are structurally activated and work as room separation at the same time. It further leads to a pillar-free layout. Woven reed on a metal grid is used for the workshop-doors.

BUT WHY WOODEN SHINGLES?

FOUNDATION

Wooden shingles are a traditional roofi ng material in Europe, but haven't been considered in Africa jet. They are simple to make even by hand and if done right, a wooden shingle roof can last a very long time. With the application of a shingle roof in my design, I want to introduce this technique to the local community and start a shingle-production in one of the workshops. Not much machinery is needed for the production. 2

ROOF STRUCTURE

One structural system: A simple wooden structure generates a giant roof, which shelters a whole row of buildings and generates a lot of shaded outside space in front of the workshops. The use of the "Zollinger"structure system enables a pillar-free layout.

Working with topography: The foundation of the building is made out of concrete. This guarantees a stable foothold on the steep site. Strip foundations are positioned under each load bearing wall. A 30cm thick rammed earth layer creates a fl oor for the rooms. Bricks are used for stairs and the walls facing the courtyard. The function of the foundation platform is not only to provide a solid anchoring to the ground, but also creating the terraces to have leveled out courtyards and no stairs in the workshops. 11

T WO AREAS

The two buildings each provide space for workshops and accommodation. The workshop spaces are on the north-east part, where the passageway goes through. These areas are a bit more public and are also closer to the street, which makes deliveries of new material easier. The accommodation, which consists of two apartments on the upper building (a larger 4-bed apartment for longer stays and a smaller 4-bed apartment for shorter visits) and a 20-bed dormitory all are in the south-west part, and therefore in a less noisy, more private area, which is closer to the surrounding nature as well. Each of these accommodations have their own sanitary facilities and provide inside space for activities in the evening or during cold or rainy weather. Large terraces are part of every workshop as well as every accommodation and provide

FLEXIBLE WORKSHOP SIZES

Workshop spaces are available in two sizes, a smaller space in half a building segment and a larger space occupying a full segment. This allows a great fl exibility in the different crafts that can take place here. The bigger segments can also be divided fi rst by non-bearing walls, until a business is ready to expand to a whole segment. Each segment always has a front-terrace and a backside-terrace, providing a spacious sheltered and shaded outside area, still under the roof. The large workshop doors can open up fully to these dedicated outside spaces and can extend the usable workshop space a lot. Generally, the dedicated outside spaces in front of the workshops are the main working areas for the craftsmen, since most people rather want to work in front of their workshops than inside.

1.1

INTRODUCTION The three aims of our design are to strengthen the community in Kashenshero by supporting the exchange of knowledge and techniques, thereby helping people to become selfemployed and enhance the economy. Currently, 70% of the Ugandan population is working in the agricultural sector, especially in rural areas. Nevertheless, agricultural yields correspond only a small part of GPD and agricultural products are imported from distant countries, e.g. cereals from Europe and South America. To strengthen the local economy, knowledge and techniques should be mediated to local people in order to be able to plant these products themselves, whereby we have been particularly concerned with wheat. To demonstrate the production process from the beginning to the end, spaces between our four buildings are used as cultivation land. We build a mill for processing grain to flour and a bakery to finish the flour to bread. Theoretical knowledge about plantation is taught in seminar rooms.

near the road. There is a public square with Boda-Boda Station and a water fountain. Deeper in the property, the space becomes more private and is used as the exterior space for the gathering hall. This private area is delimited from the road by trees and power lines. To the south of the gathering hall, open spaces are used exclusively as training grounds and the mill is only accessible from the street via a small courtyard.

These four bars follow the natural topography of the property in their orientation. Thus, they are screwed radially, so there arise tapered EXTERIOR surfaces in between. The slopping topography is fully used, mainly for educational cultivation. Open spaces are mainly used as arable land in the form of the four-fi eld plantation.

Anja Geiger

The most public building is the Bakery. It is the entrance of the Community and Trainee Center and with its visibility, it represents the concept of the entire center: sharing knowledge. In the bistro, agricultural products that are cultivated on the site are sold in the raw state or further processed as bread in the bakery. New foods shall be established that will enable a more diverse diet. The bakery also creates a new commercial center in Kashenshero, which is dealing experimentally with new food products. The building of the bakery as a public center establishes a relation to the surrounding buildings with its structure from public to private: shop - living space - sanitary. The building separates both squares, the public square with water access point and Boda Boda Station from the rather private place for events by its north - south orientation, but at the same time forms a connection between the squares through its openness. It should be a place of gathering, meeting and fellowship. A profane counterpoint to the church, for example a gathering place after the mass.

243

MEETING The building is based on a grid with four elements, 3 that are closable and one that is completely open: this area functions as a public shaded space as a meeting and common room. Small seating niches for retreat or communication create a high quality of stay. The bar is rather closed in north and west direction and only opened through a perforation in the brick wall. To the south and east, the facade is open or openable. On these sides a shaded pre-zone emerges, a transition from public to private. FLEXIBILITY AND EDUCATIONAL PURPOSE Openable and closeable rooms allow a high fl exibility of the fl oor plan. A smaller room can be used as a daily bakery or for workshops or course events the room can be enlarged. To foster the exchange, the bakery can be also visible from the bistro through openable elements. So the visitor is confronted with the concept of the center, he can see what is happening behind. ROOF AND ATMOSPHERE The roof shape is a mixture of a shed roof and a vault. Massive parts are made out of clay bricks, the open side is a steel frame and slat construction worn. Most of the time, the slats cause indirect light falling on the clay brick wall, which creates a cozy, pleasant atmosphere inside the room.

CLIMATE DESIGN CONCEPT THERMAL MASS

Through the use of clay bricks in a very wide thickness, a good temperature of the rooms can be generated. During the day, the wall stores the sun's heat and releases it at night. At the same time, the cool air stored overnight is released into the room during the day. VENTILATION

SLATS

245

The slats are inclined, so that the weaker morning sun shines directly into the room, but from 9 o'clock the sun is held out. The higher the sun is, the more often it refl ects and the less radiation comes into the room. Rain water is collected in the troughs of the roof and dissipated laterally. In the case of vertical rain, the slats can be kept open and no rain comes in; in the rare case of horizontal rain, the slats can also be closed.

A natural ventilation in the room works automatically through the roof construction. The shed-vault construction creates a negative pressure in the cavities, so that the upper, warm air is drawn out of the room, while cool air enters into the room from below, from the shaded pre-zone. The height of the building also generates a better ventilation.

Natascha Fakler

As the third step of our four step concept the gathering hall is located between the bakery in the north and the mill in the south. With its four big barrel vaults it's the boundary of the place and represents the sense of our concept. As it has the function of education, it's a very important point for learning, meeting and communication during the day as well as during festivals or other events. The access to internet opens up entirely new possibilities and should encourage knowledge and communication. Due to pure use of local materials with new construction ideas it has an exemplary function for other buildings in different scales. People can learn from it as the construction is hold very simple and clean.

The rooms for the gathering hall are equipped with a double us. On the one hand it's daily used for education. Lessons for the farmers and students on the training center with class rooms of 80qm. On the other hand if needed movable doors and foldable walls can generate a huge indoor and outdoor space for big events. Therefore doors facing the place can be hide and walls in the valley of the arches can be opened to the site. Due to sloping space, the assembly hall is ideal for lectures and services as well as other events. Benches in the inside and outside of the facade creates a welcoming space typical for Ugandan buildings. LIBRARY

Next to the classrooms, separated by a corridor, is the library located. It's more on the private and quieter area, perfect for reading, learning and browsing. The library gets its diffuse light also due a light dome for a calm and continuous daylight. In addition the walls are perforated to get light and air inside, but to keep the private and introverted character

Anja Geiger

As a solitaire at the southern end of the property, the mill tower already marks the community and training center from a distance. It represents an innovation of multi-storey construction and the technique of a mill in rural areas. The mill should help to establish new products by providing simplified processing options on site. The technical renewal optimizes work steps. At the beginning only the most necessary machines should be used, and as the center is enlarged, the mill can be supplemented with additional machines that additionally speed up work processes. The mill is the core of the project as a symbol of innovation and strengthening of agriculture.

The supplier building houses various uses that belong to the mill. These include storage areas and silos, offices and covered outdoor work surfaces. Like the bakery, the bar has a protruding roof that generates a shadowed pre-zone.

The mill consists of two buildings: the introverted, distinctive tower and a supplier building. Similar to the bakery, the floor plan is based on a grid of seven elements. Four grid elements are filled by the supplier building and two are filled by the mill tower. A space is created between the two buildings.

TEACHING PURPOSE

As in the bakery, the visitor should always be confronted with the content of the center. Wherever possible, cereals are exhibited and The mill tower is three-storeyed to generate mill-work is presented as transparently as optimal work processes in the mill.

CLIMATE DESIGN CONCEPT THERMAL MASS

The Tower also works with thermal mass and wide wall thicknesses: During the day, the wall stores the sun's heat and releases it at night. At the same time, the cool air stored overnight in the room during the day. Small, always open windows generate a constant ventilation of the room. TOWER VENTILATION

Openings can be opened during daytime use to ventilate the room. At night, the room is ventilated by small joints between the wooden slats in the doors.

In order to avoid air heating up in the building, a double roof structure should ensure constant ventilation under the roof. Perforations in the brick wall allow air to blow through the building. VENTILATION SUPPLY CONSTRUCTION

A natural ventilation in the room works through the roof construction on the same way the bakery roof works. The shed-vault construction creates a negative in the cavities, hot air will be blown out and cold air comes in from the shaded front area. WATER AND ENERGY

The upper roof construction has a metal cover with 2 ° slope. Through a gutter, the water is collected and directed into the cyst. Electricity is produced in solar panels on the roof of the mill tower and distributed from there to the other buildings.

The excursion was mainly led and organized by Derick Kwizera, who himself grew up in Kashenshero and initiated the project. The students were also accompanied by Tobias Klaus, specialist for energy supply and sustainable development, with a focus on the Global South at the University of Paderborn and by Christian Degenhardt, academic assistant at the Chair of Building Technology and Climate Responsive Design ABK Stuttgart. The trip was divided into two parts: 1. Further development of the project at UMU within workshops 2.Trip to Kashenshero and presentation of the projects to the community

UGANDA ST. MARTYRS UNIVERSITY

The main campus of Uganda Martyrs University (UMU) is located in Nkozi - about an hour's drive south-west of the capital Kampala. There are about 5000 students enrolled in seven faculties.

After landing in Entebbe, the UMU Campus was the first destination on the trip. There the group from ABK Stuttgart finally got to meet the students and academic staff from the UMU, whom they had previously only had contacted trough e-mail. The ABK students were invited to stay close to campus in a student accommodations. A one day trip to Kampala, the Capital of Uganda, was arranged and the UMU Students gave an architectural sightseeing tour as well as a talk with Felix Holland from Studio FH Architects was set up. The students got a chance to get to know each other, to exchange ideas and work together on the project. Within the workshop, the different architectural propositions from each student, UMU and ABK, were presented, discussed and combined in order to prepare a group reviewed presentation for the Kashenshero Community Representatives.

FACULTY OF THE BUILT ENVIRONMENT

The faculty is a multidisciplinary faculty with the Emphasis on Environmental Sustainable Design (ESD). Within the Faculty of Built Environment different degrees can be obtained: 1. Bachelor of environmental design 2. Graduate diploma in environmental design 3. Master of Architecture M.Arch. 4. Master of landscape architecture 5. Master of environmental design Six students from the Master of Architecture programme were involved in the community centre project during the same period as the German students. The different ideas are now being discussed, exchanged and tried to unite in workshops.

Overall the first days were work-filled for the students and a great start to bring the intercultural group socially together. The openness on both parts and the mutual interest in ones culture made this a valuable experience for all participants on many levels.

GROUP 2: ECONOMY

After the presentation of the projects by the respective authors, the key points of the individual projects were filtered out to form three groups of specialists. Over a total of two days, approaches, ideas and concepts were considered, completed or, in the best case, brought together from different drafts within these groups. GROUP 1: SOCIAL

The members of this group focused in their respective drafts on the impact on social life within the community and what added value the community centre can create in this context. The main focus was on the subjects of women empowerment and social interaction and how architecture and the utilization can be supportive.

STUDIO UGANDA

Promoting the local economy is a central point in the development of the community centre. Which spatial conditions and innovations can strengthen it? In what way can a change or improvement in agriculture, for example, contribute to a growing economy? GROUP 3: EDUCATION

With regard to the promotion of the economy, education is always a coupled issue. Not only the innumerable children of the community, but also young adults should have an opportunity for a better life through education. The community centre plays a major role in this respect, by providing the conditions for being a place of knowledge acquisition through a certain user programme or specific facilities.

RESULTS

Each group followed a different approach and a different way to reach a result. Projects were selected for further consideration, but the main aspects of all projects were filtered out in order to create an overall system. It soon became clear that the work of half a year respectively invested in the projects, cannot be revised and interpreted differently within a two-day workshop. So the focus was on a joint brainstorming within the groups, in which the approaches and concepts of the different projects were discussed and proposals were worked out together, where each individual project can be supplemented and extended by the proposals. In this way, the understanding of the culture and the possible course of events within the community centre was strengthened and therefore each individual project was solidified again.

After the tarred road ends, there are a few more kilometers to go until you reach the trading centre of Kashenshero. Now the students see for the first time the meadow on which the community centre is to be built. The destination: the church. There the group is already expected by the priest and is very warmly welcomed. After getting to know each other, the site visit begins immediately and many things become clear which were previously uncertain.

hospitable and open-minded people who show a lot of interest in the proposals for the community centre. A visit to the health centre, the clearly the poor hygienic conditions and the lack of equipment and doctors. The next stop is the Bubangizi Secondary School. In this school over 1000 students study and live. The students guide the visitors around the grounds and are happy about the interest in them, their school and are very curious about the German visitors. SUNDAY MASS

Everyone was invited to the Sunday mass in the church of Kashenshero, a special event for the whole town. Especially for the German participants this was a cultural highlight of the trip, which will be remembered forever. After a wedding and the normal Sunday mass, the priest introduced the visitors to the whole congregation and explained the intentions of the UMU-ABK project team and their propoA TOUR OF THE VILLAGE sals for the community center.

cuss the proposals and possibly find a project in which direction it should go. This turned out to be extremely difficult as the parish council liked the five presented projects very much. For them, the best solution would have been to merge all the projects into one, which would of course be difficult to implement from an architectural point of view. After Sunday mass the residents and future users were given an overview on the project proposals by exhibiting the presentation plans of all ten architectural propositions from all students originally involved from the start at FoBE and ABK. The interest in this small exhibition was very high, especially by the children as it can be seen in the picture. Accordingly the anticipation of what would happen in their village was high as well.

The newly planned Community Center should create identity and strengthen the sense of community. A center that will also work in 20 years . It is designed to integrate all cultures, tribes and religions and participate every family, old man and graduate and every farmer. In the Community Center should also provide education. There are different strategies. The education and the know-how are promoted in different areas. For example, in the library, Internet café or the experimental garden. The community center is a central place for participation, education and production. Through the space program and the complexity of construction and the understanding of living together in a community, these attributes are fueled to a result. Through an intercontinental and inter cultural dialogue and a participatory process with the community of Kashenshero, the community center project creates an intensive bond and an extremely strong cohesion between all participants. Through the accomplishments achieved so far collectively and with the common goal in mind, a message for the future is sent for the community in a particularly effective and sustainable way. In addition to the process of the project, the special design supports the economic development and the social interaction of the community. Within social and sporting activities, further education opportunities and health-promoting measures, the architecture of the community center provides a platform for the exchange of information and for people to come together.

MASTERPLAN CONCEPT

307

The community center creates a place where each individual has the opportunity to develop personally and professionally and where education, training and research leads to prosperity. Through the local cultivation of agricultural products on the demonstration farm and further processing in the learning kitchen, new and advanced training measures and innovative business models can be developed thus contributing to the economic growth of the entire community on the one hand and to the Uganda Vision 2040, the path to a middle-income economy country, on the other. The aim is also to introduce a new timber construction method and thereby demonstrate that a economical and sustainable construction method can be used to create buildings that require little maintenance and yet last for a long time.

PROGRAM

ACCESSIBILITY

SPACE PROGRAM

The space program is a variety of everyday needs and considerations of activating the place to support education, opportunities and visions. In an agriculturally influenced space and places are needed for experimenting and researching. For this purpose, new workshops are to be created. A new common kitchen as meeting area and learning place. The focus is always on the coming together and gather. Furthermore, kiosks will be available for the necessities and a small pharmacy, an Internet cafĂŠ for international exchange and research. An entrance zone designed as a pavilion with generous sheltered roof. In the pavilion, the residents of Kashenshero get attracted at the first station at the water kiosk and are supplied. This water kiosk is self-sufficient by the water cycle and offers work. The inhabitants are activated and entertained by several stations. There is an event hall and next to it a sports bar. In addition, there is a bank that provides a degree of independence and a library for acquiring skills and a retreat for students.

309

The extension of the development is divided into several phases. In the first phase a part of the roof complex will be built and then the second part. The buildings below can be built in the next phases. Box for box. This system can be used indefinitely and can be connected to the new building complex. In another situation, the concept / system can be more variable and be thought of being double and divided or added in small or large structures.

CLIMATE CONCEPT

CLIMATE RESPONSIVE DESIGN In order to react to the existing climate issue in the building sector as well, it is absolutely necessary to respect the local climate and act material-consciously. Within the community center, passive design strategies were applied to enhance the resources that are already locally available and can be recycled in a closed cycle (wood, air-dried clay, water). Especially in terms of water, a system has been developed that addresses water collection, water usage and natural wastewater treatment. The wooden construction also demonstrates an innovative and sustainable method of construction and is intended to serve as a role model for other public and private buildings. In addition, the focus has been placed on a climateresponsive design, guaranteeing ventilation and preventing overheating.

In addition, a simple roof structure is provided, consisting of multi-layer panels and corrugated sheet metal. The construction is to be made of local eucalyptus timber, with A-supports forming the basis of the structure.

The masonry is not exposed to rain, airdried bricks are used. The advantages of air-dried bricks are, on the one hand, low consumption of resources and, on the other hand, their return to the natural cycle. The interspaces are given a special quality of stay due to a high ridge height and at the same time the ridges are formed with transparent elements to provide suffi cient daylight in the interspaces and in the interiors.

WATERKISOK AND THE WATERSYSTEM

315

In the community centre, the scarcity of running water will in future be solved by the water kiosk and an exemplary water cycle, which can be adopted in other Ugandan villages.

The water kiosk supplies the inhabitants of Kashenshero with drinking water, which is collected from directly fi ltered rainwater using solar energy. Furthermore, the location of the water kiosk is a central and social meeting point where people can satisfy their daily needs and where they are encouraged to exchange ideas.

at the waterkiosk, the water is first filtered to generate safe drinking water

hand washing sinks in front of the restrooms teach hygiene

a small lake at the bottom of the site collects unused water and saves it for dry periods

small cesspits dispense water to the planting zones of the demonstration farm. They store the water and release it slowly. This helps to withstand drought periods. Waterflow can be controlled manually by a valve at the water collection canal.

water for washing fruits and vegetables and for cooking is available in the kitchen. A second tap on the outside of the building serves the preparation zone

the laudryroom makes use of the soft rainwater, no special treatment or filtration needed

Water Usage 1.9

Water Waste 2.1

S. MATAR â&#x20AC;&#x201D; L. LEHLE

MARKET SQUARE

MASTERPLAN

ECOLOGY ENERGY NEEDS: The process of collecting and cleaning water is entirely driven by gravity. The Incline of the site enables a completely natural water fl ow from each usage point to the treatment facilities at the lower parts of the site. Electricity, generated by the solar panels on the roof, is only needed for fi lling up the water reservoir on the highest point of the site and to serve the evacuated tube collector (solar thermal collector)

NOTE: The detailed planing and layout of the wastewater treatment facility Has to be done by an expert! The sizing of the facility has to be determined according to actual use and amount of wastewater.

Which produces warm water with warm water supply: Warm water is available in the laundry room, to improve cleaning. It is being produced by an evacuated tube collector (solar thermal Collector), which only uses sunlight to heat the water. The water fl ows slowly through vacuum pipes, which are exposed to the sun. An insulated storage reservoir on top of the collector stores the water until its needed. MAINTENANCE: The whole wastewater treatment facility needs only few maintenance: The settler has to be cleaned about once a year and the reeds on top of the natural gravel fi lter might need some care from time to time, Since they are inevitable for the system to work properly.

Advantages of the clarifi cation: Constantly controlled operations Constant control of the purifi ed water Constant maintenance Reliable system Cheaper in operation Direct energetic sewage sludge utilization possible Reuse of fi ltered out sand & gravel can treat heavily polluted water

NATURAL GRAVEL FILTER THIS NATURAL FILTERING SYSTEM CLEANS THE INCOMING WASTEWATER THROUGH BIOLOGICAL CONVERSION, PHYSICAL FILTRATION AND CHEMICAL ADSORPTION. DIFFERENT LAYERS OF GRAVEL PROVIDE AEROBIC, ANOXIC AND ANAEROBIC ZONES FOR THE DIFFERENT TREATMENT METHODS. A PLANTING WITH REEDS ENSURES THE OXYGEN SUPPLY IN THE UPPER (AEROBIC) LAYERS.

NOTE: THE DETAILED PLANING AND LAYOUT OF THE WASTEWATER TREATMENT FACILITY HAS TO BE DONE BY AN EXPERT! THE SIZING OF THE FACILITY HAS TO BE DETERMINED ACCORDING TO ACTUAL USE AND AMOUNT OF WASTEWATER.

MAINTENANCE: THE WHOLE WASTEWATER TREATMENT FACILITY NEEDS ONLY FEW MAINTENANCE: THE SETTLER HAS TO BE CLEANED ABOUT ONCE A YEAR AND THE REEDS ON TOP OF THE NATURAL GRAVEL FILTER MIGHT NEED SOME CARE FROM TIME TO TIME, SINCE THEY ARE INEVITABLE FOR THE SYSTEM TO WORK PROPERLY.

WARM WATER SUPPLY: WARM WATER IS AVAILABLE IN THE LAUNDRYROOM, TO IMPROVE CLEANING. IT IS BEING PRODUCED BY AN EVACUATED TUBE COLLECTOR (SOLAR THERMAL COLLECTOR), WHICH ONLY USES SUNLIGHT TO HEAT THE WATER. THE WATER FLOWS SLOWLY THROUGH VACUUM PIPES, WHICH ARE EXPOSED TO THE SUN. AN INSULATED STORAGE RESERVOIR ON TOP OF THE COLLECTOR STORES THE WATER UNTIL ITS NEEDED.

ENERGY NEEDS: THE PROCESS OF CLEANING THE WATER IS ENTIRELY DRIVEN BY GRAVITY. THE INCLINE OF THE SITE ENABLES A COMPLETELY NATURAL WATER FLOW FROM EACH USAGE POINT TO THE TREATMENT FACILITIES AT THE LOWER PARTS OF THE SITE. ELECTRICITY, GENERATED BY THE SOLAR PANELS ON THE ROOF, IS ONLY NEEDED FOR FILLING UP THE WATER RESERVOIR ON THE HIGHEST POINT OF THE SITE AND TO SERVE THE EVACUATED TUBE COLLECTOR (SOLAR THERMAL COLLECTOR) WHICH PRODUCES WARM WATER.

The roofed pavilion, which forms the head of the fi rst bar, serves as an entrance area and, with the function of a water kiosk, represents a meeting place. Rainwater is to be fi ltered at the water kiosk so that drinking water can be tapped directly. In addition, a further public tap is to be built, which will be connected to the national water network, thus promoting its expansion. Furthermore, a laundry room, a bank, a pharmacy and a kitchen will be integrated. In the second block are the administration with a meeting room, a library with learning and reading zones, a sports bar and the multi-purpose hall. The multi-purpose hall includes toilets and a technical room for the solar system. The individual interspaces have an overarching function linked to the use of the space.
