ABSTRACT INHABITABLE PRODUCTIVE LAND is an architectural and urban approach for a solution to the existing lacks and problems in a determined area. The area tackled with this solution is related to the unidentified territory present between an urban settlement and a very productive agricultural zone. This project, inspired by the rapidly growing world population and its subsequent food demand explores the possibility of introducing a self-sufficient patch in terms of agricultural products within the previously mentioned unidentified area. The integration of a productive area within and residential solution at an architectural scale is the first challenge tackled for the creation of a connecting global system that is both producing food and hosting the consumers. Through this project, it is shown how creating integrated areas of different uses could be an important contribution for more sustainable and responsible future cities.

INHABITABLE PRODUCTIVE LAND Emergent Technologies and Design


INTRODUCTION The increasingly rapid world population growth leads to an increase on the food demand and creating an extension of the area dedicated to agriculture. The rural zone is being expanded at the same time as cities are too. Up to the discovery of greenhouses system as an industrialized agriculture system, the traditional way to satisfy these two requirements had been through the reduction of forest surface. The innovation and research on plastic materials has had an incredible contribution to the permanence of this system as one of the most effective manners to produce food without being vulnerable and dependent of the site context. Agrarian cities that tend to integrate residential with agricultural uses at the same area has been an interesting topic of study in architecture for the 20th century. Almeria, south of Spain, with the largest concentration of greenhouses in Europe, produces millions of tones of products every year to feed a high percentage of European population. Furthermore, it mean important benefits on site at a local and regional scales, not only reducing the transport and logistic issues but contributing to the development of the local economy creating jobs directly and indirectly.

Greenhouses expansion and Population | 1974

2005

The world population is increasing rapidly. By the time this dissertation has being written, 7 billion people is already inhabited in the world. This will lead to the staggering impacts which are direct or long term influence. Living space, food supply, fresh water supply, and energy resources are some of the necessities that will be in shortage condition. As the United Nation predicted, it is believed that the world population for the next 30 years will reached 10 billion people which means the problems that have been mentioned before will become cumulative matter if not treated immediately.

The United Nations Food and Agriculture Organisation (FAO) estimated that to meet the need of the 10 billion world population, the farmers will have to provide 70% more food however most available farmland is already being farmed, and also the productivity is decreasing because of soil erosion and wasting of water. A major ‘sustainable intensification’ of agricultural productivity on existing farmland will be necessary.

On the other side of the story, the emergent of greenhouses in Mediterranean basin especially in south of Spain has arising rapidly. This is due to the temperature rising during the past 30 years. Where we can see it as a sea of greenhouses in the area, there are several residential unit that needs to be around the area as a housing for workers and as a neighbourhood of people who already live in that area. While only living in the urban area is already uncomfortable due to the hot arid climate, imagine housing surrounded by reflective plastic of greenhouses where people still need a comfortable area to settle in these circumstance. this opposite phenomenon will lead to the question: “HOW DO WE LIVE WITHIN THE GROWTH OF GREENHOUSE AND EXPANDING OF CITY”

16

INHABITABLE PRODUCTIVE LAND Emergent Technologies and Design

The UN also reported that climate change coupled with poor farming practices make the productivity of the world’s farmland decreasing, 25% of the farmland is now ‘highly degraded’ with soil erosion, water degradation, and biodiversity loss. Another 8% is moderately degraded, while 36% is stable degraded and 10% is ranked as ‘improving’. In Western Europe, highly intensive agriculture has led to pollution of soil and aquifers and a resulting loss of biodiversity. 70% of fresh water in the world use for growing food however the population still need fresh water supply for their needs. Recycle and reused the waste water and rain become potential solution to be looking forward. The fresh water resource around the world is becoming even scarcer and salinized, while groundwater becomes more polluted by agricultural runoff and other toxins. In consequence to that, irrigation technology system must become more efficient because most of the systems that perform now are below their capacity.

Metabolism study for urban settlement

Image1. Agricultural city by Kisho Kurokawa Source: http:// metteingvartsen. net/2011/09/giant-city/

Overview

Metabolism movement

In Agricultural city project by architect Kisho Kurokawa, Metabolism derived the idea where natural growth is provided as a grid system. Each of the square units composed of several households autonomously, Clustering units together to creates a neighborhood. Residential unit multiply spontaneously without hierarchy as traditional rural settlement which has developed throughout history of Japanese. The method of this referred as metabolism.

Metabolism movement formed by a group of Japanese architects and planners in 1959. It has an idea of the ​​ city of the future inhabited by a high density characterized by large scale. With fexibility and transformable organic growth, the precursors of this movement believed in a deep influence of space and functionality on the society and culture of the future.

The project takes into account not only the bases of Metabolism movement, but through the study of the individual clustering cell with the concept of urban living quality and living in natural environment. The analysis of an environment greatly involved in the project which leave the configuration and management of open spaces, public circulation spaces, built up area.

Despite the sometimes otherworldly designs, the ideas took hold and continue to inspire architects today.

Biological Metabolism In any biological organism, there are flows and processes of energy and material throughout it. This metabolism develops with the organism’s morphology, emerging together through dynamic forces acting upon them in the conversion and movement of resources throughout the organism.1 All living forms must acquire energy and material from their environment, and transform matter within their bodies to construct their tissues, to grow, to reproduce and to survive.2 In an analogical manner the urban system needs resources to perform and grow.

Urban Metabolism The current question nowadays is indeed related to the fact that the needed resources are coming from outside. “The most densely populated regions in the world consume biological resources at more than twice the rate the ecological systems at these regions can regenerate. Currently, more than half of the fuel energy consumed in western areas is already imported from other places.3 These regions are no longer generating their requirements but are dependent of other regions’ production. Therefore, this increased demand limits its expansion. There are many indicators that suggest that the system is close to the threshold of capacity.4 The current architects, planners and developers’ interests might lead to the study and design of new urban patches that minimizes the external resources consumption. This new systems will be able to produce most of their own needs while hosting a sustainable development.

Located at southeast of Spain which has direct connection with provinces of Granada, Murcia, Almeria positioned in Mediterranean Sea basin that makes climate become subtropical desert arid. The total area of this province is 8,774km2 which is ranked 27th in Spain. Inhabited by 691,764 inhabitants in 2014 census (ranked 23th in Spain) which mean its population density is 79.7/km2 for the province that slightly lower than Spanish average. An interesting fact which has been found by the census reports from IPCC and INE showed, Almeria is the only province in Spain that has increased number of population and economic whereas larger provinces like Madrid and Barcelona were having deflation caused by Europe global economic crisis. One of the reason is the geographical condition, Almeria is one of the most productive agricultural zones in Europe with more than 10,000ha of land cultivated commercially (greenhouses). Despite of this expand, These sea of plastic greenhouses along the sea side create the “Albedo effect” which make the temperature around Almeria decreased by 0.3°C per decade reaching a balance of virtually zero change since the temperature risen during the 1980s. These greenhouses industry are cultivated by immigrant workers, around 100,000 legal and illegal workers are believed to work in the facilities with their low wages and lack of rights are thought to help the businesses remain profitable. The facts that Almeria has very little amount of water resources due to its lowest rainfall and driest area in Europe with annual precipitation average which only 226mm (226litres/m2), make it lack of fresh water but it has the highest hours of sunshine 3050 hours/year which make Almeria become home to Europe’s largest solar energy plan (The Solar Platform of Almeria)

Permaculture is the systematic method framed in 1978 by two Australians (Bill Mollison and David Holmgren) as an integrated approach to designing healthy, productive, wildlife friendly, places and communities in-away this system also create sustainable architecture that able to maintain the habitat by itself. This system working side by side with natural ecosystems without interrupting them, even make the existing condition become more productive because permaculture is emphasizing the landscape patterns, the function of the land, and the relationship how each element is placed in coherency with each other. In the end a high level of synerWgy come out as the result with maximal benefits that able to produce big amount of food with least input and no waste. This permaculture is developed from several disciplines, some of them include organic agriculture, agroforestry, integrated agriculture, sustainable development, ecology study. The word “Permaculture” formerly referred to “permanent agriculture” but was expanded to stand also for “permanent culture,” as it was seen that social aspects were integral to a truly sustainable system as inspired by Masanobu Fukuoka’s natural farming philosophy. The three core principles of permaculture are: Care for the earth: Provision for all life systems to continue and multiply. This is the first principle, because without a healthy earth, humans cannot flourish. Care for the people: Provision for people to access those resources necessary for their existence.

28

INHABITABLE PRODUCTIVE LAND Emergent Technologies and Design

Return of surplus: Reinvesting surpluses back into the system to provide for the first two ethics. This includes returning waste back into the system to recycle into usefulness. The third ethic is sometimes referred to as Fair Share to reflect that each of us should take no more than what we need before we reinvest the surplus. In Architectural approach, the settlement can be integrated into the ecology of the site. To meet key human needs of food, water, energy and shelter in a way that also enhances the natural environment. By understanding how biological systems work in nature and applying them to human settlement design, these principles can be harnessed for productive and biodiversity environments that are low-maintenance and self-perpetuating.


“Permaculture is a philosophy of working with, rather than against nature; of protracted and thoughtful observation rather than protracted and thoughtless labour; and of looking at plants and animals in all their functions, rather than treating any area as a single product system.

Urban Transition | Image1. Almeria Site Map Source: Google Earth

Considering the necessity to define new categories for a better understanding of the city and its urban phenomena within a context of growing urban territories, it raises the question of defining the concept of “urban transition” as a new territorial category attached to multiple and dynamics meanings. Nowadays, although the meaning of ‘urban transition’ is still undefined, it is a topic of importance as much in the theoretical as in the practical ambit of the architecture and urbanism. Particularly in the cities of the Mediterranean basin, which have experienced a rapid growth in the last years, the limit or edge, which marks where the city ends and where the countryside starts, has reached a high level of complexity. Kevin Lynch states (1959): “Edges are the linear elements not used or considered as paths by observer. They are the boundaries between two phases, linear breaks in continuity: shores, railroad, cuts, development edges or walls. They are lateral references rather than coordinate axis.” 1 This phrase could could be applied to American cities, but in the Mediterranean basin cases, this space of transition is no longer a linear element and has more than one dimension in space. Human settlements, as organisms that are not anchored to their forms, they grow and shrink at the same time. Therefore, the formation process has enlarged this space in some areas up to thousands of meters, creating an undefined space with no use, waiting to be either built up or redeveloped or left. Beyond those limits or area of transition. The adjacent urban area is affected. Since this zone is usually related to a single use, i.e. residential, and is next to the limit, it lacks of a good distribution of infrastructures, facilities and productive activities that would meet the population requirements. Subsequently, it creates social, environmental, economical and political problems caused by that lack of opportunities.

INHABITABLE PRODUCTIVE LAND Emergent Technologies and Design

For this dissertation, the approach to urban transition is similar to that one introduced by Barsky (2005) 2. He defines it as an inter phase between two geographical types, in this case these ones are referred to as urban areas and rural areas. This concept implies multiple dimensions that overtake those conventional ones from urbanism. Therefore it adds a vast complexity to the territorial planning. In this multidisciplinary work the transition will have several names such as “urban periphery”, “ Peri-urban area” or “urban transition”. The unidentified urban transition between urban and rural territory brings spatial quality issues, especially for cities located on Mediterranean coast. The rapid city growth that pushed the agricultural territory to outer part of the city and also speculators ambitions-based development of cities are some of the reason behind this abandoned territory. Bringing the agriculture back inside urban territory, could be one of the potential solution, create a symbiotic relation between two different functions. Other potential benefits that could be achieved include modulating mechanisms in a small scale which are able to manipulate the extreme macro climate, providing locally based food resources that will reduce fossil energy waste and also ecologically sustainable urban tissue. The proposed system in this dissertation will be tested within this space of contact and encounters. This area offers the possibility to overlay the desired conditions on current situations. The system will be focused then on a new patch that combines urban zones with productive land. It will also aim an appropriate distribution of networks that connects to the existing city as well as the self-sufficiency in terms of food and energy.

Industrialized Agriculture |

Product Comparison

Production in Mexico, Spain and Netherlands. Three of the most important cases of concentration of greenhouses are in the western part of Netherlands, the state of Puebla, in Mexico, and southern Mediterranean seaside of Spain, Almeria. In the case of Mexico, the infertile soil which the states of Puebla and Queretaro laid on makes farming unlikely to succeed. On the other hand, the low rainfall regime and high temperatures are suitable for the installation of greenhouses. The mix of clay, sand and manure converts this arid soil into the appropriate one for most of crops. Nowadays, this type of industrialized agriculture occupies 2500 hectares.

Image2. Greenhouse in Spain Source: Google Earth

Netherlands is the major exporter of flowers, plants and bulbs. The industrialized horticulture, distributed over 39000 hectares, in the region of West land is focused towards the production of flowers and plants, rather than food. Nevertheless, this country production is number 3 in the world ranking of nutritional products exporters. They are the main exporter of potatoes. Its geographical good location and its soil make this fact possible. A mix of clay and sand is added to make the land more fertile and suitable for crops. The production costs are 3 times bigger than those in Almeria due to the use of heating systems. Since 1980’s the area of El Ejido, in Almeria, has developed the largest concentration of greenhouses in the world, over 42000 hectares. With the addition of imported clay, sand and manure to this land and the tariff-free exports within European union, this area has been intensively used for agriculture. Tomato is the most important product and it grows on more than 11000 hectares.

Since the three previously compared cases don’t produce only edible products, but also plants and flowers. Furthermore, the main product of all of them is not the same, therefore is not possible to compare them solely in terms of production per area. Consequently, this research was focused on the production per area of their major product, getting surprising results from the two fruits, as shown in graphs and below. How much does a tomato weight? The weight of a tomato is about 5 oz. which means between 0.14 kg. A tomato plant usually has an average of 10 fruits by the time is harvested. Therefore, the product weights 10 times 0.14kg, i.e. 1.4 kg. How much does a tomato plant occupy? For a tomato plant to grow successfully, it should occupy on its own 5 squared feet, i.e. 0,46 m2.

Image2. Tomatoes farming Source: https:// farmtek.wordpress. com/2012/07/17/ultimate-guide-to-growing-tomatoes/

How much does a potato weight? The weight of a medium size potato is about 5 to 6.5 oz. which means between 0.14 and 0.18 kg.W A plant of potatoes usually has an average of 3 fruits by the time is harvested. Therefore, the product weights 3 times 0.18kg, i.e. 0.54 kg. How much does a potato plant occupy? According to some advices from BBC Gardener’s World magazine, one potato seed must be 30 cm. apart from the next one, and rows should not be closer than 60 cm. one to another.

There was a prediction say that greenhouse will play an important role in the Mediterranean climate environment as a means for sustainable crop intensification leading to optimization of water-use efficiency in an environment of water scarcity. However, using greenhouses in industrialized agriculture has already optimized product quality, safety and fulfilled market demand by the benefits of greenhouses effect.1

The main purpose of greenhouse is to collect solar energy. The greenhouse captures light through its walls and converts it to heat where it takes only a few minutes for light coming in for raise the greenhouse temperature to significantly higher than the outside similar to cars with closed windows. Also colour of material also significant where darker darker colour within the greenhouse helps to store heat and warmer the air inside.

By collecting light and converting it to heat, greenhouse stores thermal energy and releases that energy suitably for plants. It can help moderate temperature and produce a controlled environment for plants to flourish. Furthermore, greenhouse helps to protect undesirable weather and secure the plants from pest.

Moreover, greenhouse usage improve the thermal energy release by heat up and cool down gently. Rather than high heat in the daytime and cold temperatures at night provides a suitable atmosphere for plants to grow.

Greenhouses Ventilation

Cooling effect

One of the most crucial element in greenhouse is ventilation. Successful greenhouse has either active or passive ventilation such as circulation fan, vent or even simple opening. Due to climatic zone,ventilation system of greenhouse may varies. With proper ventilation, plants could thrive prominently. Ventilation helps the regulation of temperature and humidity to the acceptable level for plants to grow. It also decrease the air flow that can harm the plants and prevent increasing of pest.

One of the last discoveries related to greenhouses has been the accidental breakthrough about its cooling effect. It has been observed that while in the whole Spanish seaside the average temperature has been increasing above the world average over years, in the case of the Almerian so-called ‘Sea of plastic’, the values have decreased 0.3 degrees per decade. Spanish scientific have linked this fact to the reflecting effect of the white plastic which cover the greenhouses. The polythene reflects the sunlight into the atmosphere as if it was a mirror, slowing down the warming of the surface.

By having proper ventilation system, Photosynthesis could be effectively done,important pollinators allow to access crops in greenhouse, improve plant respiration, and may enable important pollinators to access the greenhouse crops.

After analysing the temperatures in the 2 major stations, they shown how the values had fallen 0.9 degrees since 1980, when greenhouses expansion began. At the same time, in Murcia, Granada and Malaga, adjacent provinces, the increase has varied between 1 and 3 degrees. This study concluded that if the greenhouses have a cooling effect in Almeria changing global land use could have a really important role in global warming, much more than previously realized.

Greenhouse in Mediterranean Basin While in adjacent areas the average temperature has been increasing above the world average over years, in the almeria so-called ‘Sea of plastic’, the values have decreased 0.3 degrees per decade. The polythene reflects the sunlight into the atmosphere, slowing down the warming of the surface. If the greenhouses have a cooling effect in Almeria, changing global land use could have a really important role in global warming, much more than previously realized. Greenhouse in Mediterranean basin area usually are very low cost structures with a little climate control such as porosity or windows for natural ventilation without any high technology device. By using local materials such as wood or Polyethylene plastic film, the local workers could possibly build the greenhouse by themselves without any help from experts where it allow the expansion of greenhouse by these costs of material and availability of installation expertise. However, there are important design problem with the current greenhouses; low radiation transmission, lack of good ventilation as a result of low ventilation surface area , inefficient ventilator designs and use low porosity insect screens. Where good agriculture require good ventilation and light transmission, computer simulations show that in winter time, rising the roof slope to 45o can increase daily light transmission by almost 10% It is also recommended to build the greenhouse with an E-W orientation and with regard to ventilation, it is advisable to build the ventilators of the roof perpendicular to the prevailing winds to increase the air flow.

Although Newly design arch shaped multi-span greenhouses bring benefit to greenhouses such as low maintenance structure and continuation of farm, they are not free from drawbacks. Condensation which caused from round shape roof resulting dripping in humid and cold weather. By increasing the roof slope with pointed arches can relief the situation but it is not entirely solve the problem. While the popular of low cost plastic greenhouses expand , the glasshouse is limited in southern Europe countries. Mainly because the high costs which made glasshouses occupy less than 1 percent of total greenhouses area in country such as Spain. Glasshouses are excellent greenhouse structures Whereas if glasshouses are to be constructed in warmer area such as southern Europe, the ventilation must be improved.

In such an area like Mediterranean basin, multilayer cover material are recommended since they allow addition of the positive properties of each of the components where it could block long-wave IR radiation so as to reduce heat loss. Also Diffuse films are preferred as they improved the uniformity of light. Ventilation reduction can be modulated by emphasis the ventilation surface as in concertina shaped screens where screens with a small diameter of thread is the key to improve the ventilation as they are more porous but still can prevent insects to go inside greenhouse. One thing to be considered is that Photo-selective or “Coloured“ screens has a possibility to protects against pests. Blue and Yellow colour is likely to reduce the risk of pest invasion than other colours.

In agriculture, basic use for growing plants and trees is Soil. While soil could provide a wide range of plant and tree growing, drawbacks are very dominant to global problems .Other kinds of cultivation techniques has been raise and developed to tackle the farming and planting technique especially in industrialized agriculture field. In our proposal, cultivation techniques will take a role to increase the food production in the greenhouse volume as a reflection of occupying space sufficiently which allow the residential unit to fit in the area where still have similar production rate or more in overall total area.

Assuming this projects will take place on the arid Mediterranean basin region which has average of daily sunlight more than 5 hours, therefore the renewable energy based on sunlight turn out become the most important and also the main energy resources for supplying the project needs. The relation of this renewable energy with the project is as the diagram above shows, the photovoltaic cell will be embedded on the surface of the greenhouse which has the most sunlight exposure in all year round from the calculation, then the energy that produced by these photovoltaic cells will be used to fulfill the population electricity needs, and also can be used for heating the greenhouse temperature in the winter season. The strategy of using sunlight as renewable energy create potential for the project to become sustainable environment urban tissue.

The potential of biomass become very important for decreasing the residues from agriculture and households organic waste, considering the project dealing with agriculture issues which produce vast amount of organic waste. By changing the disadvantage become the benefits for example biogas as the result from biomass conversion will be used to produce heat energy for residential and greenhouse, and for biofuel it can be used for filling the agriculture machinery or public transport for the urban tissue. The renewable energy from biomass also contribute to turn this project become even more sustainable.

Management of water is the dominant issue to this element. Nearly one fifth of the world population is already facing water shortages on a daily basis. 500 million people in water stressed areas and almost one quarter of the population living in countries that lack the necessary infrastructure to take water from natural sources.2

Morrocan Techniques

Water consumption has been growing at more than twice times faster than the population increase rate in the last century. By 2030, the population in the world will reach 10 billion people. Moreover, one fifth of these will live in areas affected by desertification. This fact comes along the difficulty to access to a water source. In most of the cases, the solution carried out has been an expensive desalination plant. One possibility to tackle this issue is by having desalination tank which it will converts seawater into fresh water by applying a reverse osmosis process. This process is only viable where there is no other option at isolated areas or the water networks will signify an extremely high cost of construction. In this design system, not only the elements are the designed items, but also the connections and relations between them. In addition, the effort is put in an efficient recycling cycle of fossil fuel, energy and water. As previously mentioned, water could be used for either drinking, irrigation or industrial processes.

Water Scarcity

The water scarcity is a phenomenon caused both naturally and man-made. The water is distributed unevenly, a huge part of it is wasted, polluted or sustainability managed. When we talk about fresh water, this is not only the water used for drinking and domestic use, also agricultural irrigation and industrial processes should be taken into consideration.

Water Management |

One of the most promising techniques from the ancient time using by most traditional farmer in Mediterranean is Moroccan techniques. Invented by Arabs in the sixteenth century, The irrigation system of ditches and drainages is a reflection of the circulatory system of the human body. Two largest canals come directly from the river as the main ditches, taking the waters and distributing them among other second biggest channels then the second canal ditches, branching out into other successively smaller channels (Hijuelas) and will be ditches again to smaller channels which called “Armbands and Showers�. These are the last capillaries of the intricate and gigantic circulatory system responsible for driving the liquid element to each of the terraces to irrigate crops. The system also works for another important function which operating the other way around. In this second system, the surplus of water after having watered terraces and farmland, will be lead back to be exploited again. By discharging it into the river or the veins so that farmers on riverbed or located below, also able to gather water for irrigation necessities.

Tradition soil cultivation waste an amount of water in farming where in Hydroponic method are able to reuse water in the system and have zero run off which possibly effect the surrounding ecosystem. Hydroponic and Aquaponic seems to share the same features of soil-less cultivation with close loop water management. There are slightly different in many way. Firstly, Hydroponic need to be controlled by human where Aquaponic is the symbiosis system where it required less maintenance. Despite a long start up time of Aquaponic system, If able to provide an area for aquarium tank for fish, using this system require less work and could provide more benefits in a long run.

Nowadays, dripping method has been developed and become most innovative irrigation method in agriculture after the massive impact of sprinkler in 30’s.In this particular system, pump and valves may be manually or automatically operated by a controller. Micro-spray head has been used to pray water in a certain area instead of dripping emitters. Tree and vine crops which has widen root are basically used by this method. Subsurface drip irrigation (SDI) is other dripping technique which buried dropper line or tape below the plants roots. It is becoming prominent method in areas where water supplies are limited. Relevant factor such as land topography, type of soil,climate need to be analyse to match with the most suitable dripping system.

Using hydroponic system are no longer limited by climate or by season0as the plants can grow al year round by using a right amount of nutritions where temperature condition has to be considered as it may be to cold or to hot for plants to grow.

By using a proper dripping system to the conditions above,water conservation could be achieve but also by design a newer system by reducing evaporation and deep drainage when compared to other types of irrigation such as flood or overhead sprinklers since water can be more precisely applied to the plant roots. Moreover,many diseases can be eliminated by using this dripping method because it require small amount of time to contact with air. Finally,in some regions where there is water scarce, arid regions or on dry soils, water needed to be carefully used and as slow as possible to avoid waste.

Urban Farming | Ludwig Karl Hilberseimer Ludwig Karl Hilberseimer (1885-1967) was a German architect and best known urban planner, most of his essays were under strong influence by Nietzsche’s work. He became very famous because of his urban and architectural productions in his 20’s and 30’s, during these times he was very critical to Expressionism and Capitalism. Hilberseimer was interested in theorizing modern architectural practice which responded to development of industrial technologies and the corresponding transformation of the individual in society. He was also influenced by a radically abstract and technological art and architecture. By 1915 his theories on scientific management were widely applied throughout the western world. In 1922 Hilberseimer participated in the international competition of the Chicago Tribune, he became the first European response to a specifically American brief, and also ties to the first ‘tall buildings’ of 19th century. Hilberseimer criticized the lack of order of American skyscrapers, its ornament and individuality.

INHABITABLE PRODUCTIVE LAND Emergent Technologies and Design

Hilberseimer’ s idea of the city was based on an organization scheme of relations between parts, the communal block will replace the single house. The importance of the collectively in the block overcomes the individual. His model was conceived for a system with a strong central power. The city is the centre of that power, the city should be the base of the organization of large economic complexes into the nation state. At the larger scale, nation states should organize in larger units. Any individual expression is erased by order and rationality. Therefore High Rise City was a socialist city, which also Hilberseimer main interest because if the architecture icon was removed what remained behind is a diagrammatic organization scheme for the city. Activities in the High Rise City were organized vertically in it. Vertical and Horizontal circulation systems were going from home to work and thereby solving the commuting problems of centrality of the satellite city. In 1938 Mies van der Rohe invited Hilberseimer to Chicago, United States, later then he published The Decentralized City as a respond to the problems caused by industrial revolution. The first stage of industrialization was based on concentration of production and a separation between city and country, as second stage decentralization and diversification of production, both agricultural and industrial, and also closer relation between city and country. Basic settlement unit of Decentralized City contain production, agricultural, industrial, and living.

Image4. Hochhausstadt Source: https://rosswolfe.files.wordpress.com/2013/04/ hilberseimer-hochhausstadt-1924.jpg

He also explained that the cities are not just the place to life but cities also need to serve life, they must be planned for living. Bringing agriculture into closer relation with city would contribute benefit solutions for social and economic problems. Connecting urban farming directly with the house is become one option for low density area, however when the population is denser such gardens might be grouped in the adjoining open area. This farming also could contribute to provide biomass, local based food products, reducing fossil pollution caused by transport therefore this plan also could avoid the costing problems.

Settlement units which have gardens and surrounding parks will bring the city into close relation with nature, in the end the city itself will becomes part of the productive lands. For example the one-storey dwelling will disappears among trees and farming land, a natural camouflage will appear as the result. In the end when we compare the High Rise City with Hilberseimer’ s Decentralized City, both have quite different approach, however they share similar principles they became one project in two different contexts.

Placing the farming area in the adjoining open area has essential advantages such as economy potential, become productive park system, reducing the cost of maintenance because the land will be cultivate by society. The extension of this farming area would be depend on conditions such as climate and culture in that particular area, also the number of people which the area need to provide. The farming area need to be enough to produce food supply for projection population, therefore to have additional agricultural land is necessary. Some particular concentration patch would have to receive their food demand from other farming areas.

Rainwater is captured and reuse in three out of four season even though Canada has not effected by water scarce. There are two reasons to do so: First, is to avoid over-burdening the city water supply and second, is to prevent nutrient-rich wastewater from entering the public water system, where it might contribute to high algae development or the overgrowth of other plants. Greenhouse on top of an urban structures could help to reduce the transportation cost, emission and money. The heating system absorbs heat from the sun and bring to the heaters. During night time, energy curtain are applied to reduce energy needs. climatic controlled rooftop helps to create a modulate temperature in both humidity hot in summer and freezing cold in winter. In conclusion, Lufa model could be beneficial to a company where they have free space on the rooftop but there is no interaction between local community. However, there is some idea of putting greenhouse on rooftop that can decrease the sun radiation effected to the building to continue investigation furthermore.

Organoponicos , Havanas Urban agricultural system that usually found in Havana, Cuba. It was invented when Cuba hit by food crisis during the lost access of cheaply oil from Russian being cut off. During that period the urban agriculture even not exist in the Havana, on the other hand the food demands need to be provide, as the president during that time Fidel Castro proclaimed all the land should be cultivated. This policy forced the people in Havana to produce their own food supply resources such as growing vegetables also raise animals.

A low-level concrete walls filled with organic matter and soil , with lines of drip irrigation laid on the surface of growing media was invented and named Organoponicos. Many new urban individual farmers are grown in every part of Havana which than called Parceleros emerged. Usually the unused old parking lots, abandon building sites turned to be Organoponicos. In fact more than 35,000 hectares of land is turn to urban agriculture site in Havana. With this method the city of Havana believed become self-sufficient that able to provide all the food demand for the residence. However the Havana city still need to import their basic staples such as (wheat, vegetables oils, rice, etc) because the limitation of the plant variety that could be grown in limited space urban agriculture.

Frontier Cities, Africa As the continent with the fastest growing population, this project presents a way to a more prosperous cultural and economic future, erasing old colonial borders and reintegrating the continent, yet recovering lost identities. The frontiers become attractive places for human settlements. Highly density urban patches are separated by rural stripes, creating strong and clear boundaries between neighbourhoods. This fact, beside the commercial pedestrian street, that every neighbourhood has, allows for a recovery of old identities and values, formerly erased by colonialism. These new settlements present a main transport axis and the maximum length of the urban stripes are dictated by human scale and ensure a maximum 20 minutes walk to reach the axis from every spot. From the main axis, water canals provide irrigation to the agricultural plots. The energy needed is provided from renewable sources that are inside huge infrastructures whose aspect remind of that of the old and harmful sources. These pieces become appealing public spaces instead. To deal with the extreme climate in these zones, the architectural solution proposes building morphologies inspired in the local crafts patterns with long perimeters which allow for double facade and cross ventilation. The vacant land left for agriculture is owned by state and developed on a concessions scheme, within an efficient network of connection with other cores. Projects like this for trans border cities in Africa blur a border like that between countries by using intelligent and efficient mechanisms, but at the same time it creates new borders between neighbourhoods at the city scale

Bi-City Biennale of Urbanism, Shenzhen The differences in social classes, between rich and poor in the city of Shenzhen have created a segregated area, not only as a physical boundary but also as an intangible frontier. These proposals are to rethink urban phenomena and relationship between segregated spaces by revealing the facts and images behind them.

Cuisine Project uses cuisine as an important factor in the expression of local population and so it does with restaurants, which are a make up of the society. This project provides the different restaurant models with a frame made out of wood that allows for a flexible exchange area. Some urban villages of Shenzhen show vibrant streets with businesses that lead to disorder and lack of spatial quality due to competition and reduced exterior space. Market project looks for a new instrument to maintain the activity and vitality of a city but keeping it tidy and clean. It divides the street space into organic groups based on a overlaid gridded market. With a wide range of urban furniture it forms a varied and complex outer space that still looks uniform as a whole. These two projects are clear examples of urban acupuncture solutions for borders encountered in the city by exploiting small interventions in order to generate not only huge urban impact but also social changes.

Homefarm, Singapore Fully urbanized places such as Singapore has one thing in common, lack of agricultural land where farmers do not have an area to grow their crops and infrastructure projects, housing and industry are move forward to their land. As the consequence, most of its food has to be imported. Home farm project considered the technique that has been used in Singapore’s building today, Aquaponic system has been adapted to use as a building facade where the traditional soil based farming will take place in a lower ground as well as the linear soil-based will be planted on roof top and higher level. Since the proposal is to be a retirement housing. This would provide jobs for them such as planting, harvesting, delivery, sorting, cleaning, packing, tours, sales on site, and so on. The architecture has been conceived for economic construction using simple materials and modular parts. The concept offers multi-dimensional benefits related to economics, food security and quality, social engagement, health, sustainability, place making, and healthcare provision. While this project focusing on involvement of dwellers and the farm, still the system of farming are work as a passive system while the architectural application between these buildings and the system has not been merged yet with using vertical farming idea as a façade or either grow it on the ground.

Integrate vertical farm, New York This vertical farm project take place in New York City where all the area has been occupied like Singapore. 90% of its food has been imported from around the world which could effect to the overall economic status of the city and the country The idea is to integrated food growing and create an inhabitable areas. Study has to take place to collect the data needed for design the project while existed vertical farming idea use the hydroponic crops, this project included also legumes and grains which create more diversity of farming and these plant can be produce all year round. Introducing the expandable system that can grow vertically as an aggregated cells, the manipulation has been program according to site condition and program. The outer skin of the cell will be used for farming while the inner volume occupied as retail and for irrigation. The project aim to cut the transportation cost and will reducing the usage of fossil fuels as the food product do not have to travel from outside of the city for city dweller. This project shows possibility in terms of continuous system that can grows over time. However, it seems that there is only one scale in this system as a building scale, the capable of growing in to a group of buildings and in urban scale would be possible.

METHOD This design project deals mostly with an urban system. Therefore, it is not related to a minimal scale or material aspects, so the experimentation on physics tests is practically irrelevant. For a clear understanding and development of this system the methods used have been carried out using computational tools. These digital techniques have been used from the analysis of solar exposure on the first buildings designs to the evaluation of the network and cells distribution on the patch for the design proposal.

Algorithms-Aided

Image1. Darwin’s finches Source: Wikipedia

A traditional way for architectural design has been to design by drawing, a technique as well known as an additive process with no relations between elements.1 Two limits of this additive logic are firstly, the fact that the act of drawing differs from a parametric paradigm in that it works through adding information rather than establishing interrelations. Secondly, the traditional process of drawing could not include real physical information such as external forces or modify the design or form after a feedback is given. In the past ten years, Form- finding techniques have became a significant strategy through parametric design. This process aims an optimized form by organizing heterogeneous data such as dynamic force, environment, social data, etc. Parametric design has been brought up and many designers and architects realized that it could manage complexity beyond human capabilities due to it relies on programming languages which express instructions called Algorithm.

This procedure can not rearrange such as you can not eat a cookie before you spread it in a pan. Nonetheless, some may argues that it is not purely algorithm since the instruction has not well-defined what are the ingredients as Algorithm is an unambiguous set of properly defined instructions.

Algorithm Algorithm follows the human aptitude of splitting an issue into a set of steps. They are highly associated to computer. However, it could be defined as a simple procedure such as baking a cookie by introducing a step by step instruction:2 0. Mix Ingredients. 1. Spread in pan. 2. Bake a cookie in oven. 3.

Genetic Algorithms

Multi-Objective optimization

A genetic algorithm is a class of adaptive optimization mimicking the natural selection. 3 The GA is commonly used to create optimized generations of designs. A criteria set, previously defined, marks the objective pursued during this process. The iterations start with the development of a population, or generation zero, of candidate solutions to an optimization problem that can be continually evolved towards better solutions according to a single or multiple fitness criteria. It is an evolutionary process where the first population is created from random values of genes and it is then implemented pursuing the desired conditions.4

Genetic algorithms involving more than one criteria simultaneously may produce different solutions with each set optimized according to different fitness criteria.6 The multiobjective optimization algorithm allow for the option to assess the advantages and trades-off between different design morphologies comprised of mutually concurrent and often conflicting criteria.7 Utilizing multi-objective genetic algorithms in the development of an urban system allow for the investigation on environmental and cultural performances in a complex way. They will be used to decide the best orientation in order to get maximum exposure on surfaces of buildings or to define the location of the main nodes within the primary network.

The GA creations are commonly known as individuals that acquire their shapes, properties and characteristics by managing a group of parameters. These parameters, or genes, can be modified, mutated or altered throughout the process. During this iterative process, a mutation rate can be established in order to define the degree of control over the process and ease of tracking the genes. For each generation, the values of each individual are evaluated and ranked. The individuals that scored best from each generation are selected and theirs characteristics are recombined to create the subsequent generation. The process terminates when a user-defined number of generations has been reached or the population have an established satisfactory fitness level for the optimization criteria.5

Solar Analysis

Sunlight hours

Sunlight refers to direct sunshine throughout the day and experiences changes in intensity at different latitudes and times of year.8 At urban scale, it is an important factor to evaluate and test. From these experiments, some design decisions are taken in order to either obscure a specific area or let light in at some other zones.

Another important action of the sun on the Earth is the hours of sunlight on a determined surface. This project deals with the integration of industrialized agriculture and residential areas. For the industrialized areas, in this case produced within greenhouse the sunlight hours are a crucial factor. The studied greenhouse type needs 6 sunlight hours daily for a good performance.

Radiation The power per unit area produced by the sun on a determined surface is known as radiation. This energy, measured in Kilowatts heats up the space next to the surface. At urban scale, this factor becomes a relevant measurement of the increment of temperature at a given space due to the radiation of the surface. The albedo index for the material studied is necessary to know the radiation value. Once this index and the surface area of the material is known, the radiation can be found out. Therefore, the effect on the adjacent space temperature will be used as an aspect to control during the design of surfaces and streets. This system is to be tested on cities along Mediterranean basin. The reduction of the heat on the streets, particularly in summer months is one of the main ambitions of the project carried out in this dissertation.

Graph theory

Minimum spanning tree

In maths and computer sciences graph theory is the study of mathematical structures used to model relationship between entities.9 Many practical problems can be represented by graphs to demonstrate pairwise relations among objects and to process dynamics in physical, biological, social and information systems.10 A graph consists of nodes, as objects, and edges as the connections between them. In this project graoh theory has been used for area tessellation, subdivision and networks distribution.

From a given set of connected points in a graph, Minimum spanning true of that graph is created by connecting these points with the shortest length of edges and without closed loops.11 A single graph can have several minimum spanning tree and the minimal spanning tree is found by summing the lengths of each edge and comparing them to one another.12

Shortest path In graph theory, Dijkstra’s algorithm is utilized to find out the shortest path between nodes. With a given set of nodes this algorithm will find the edges between nodes so as to the sum of the lengths of its constituent is minimized. These edges can represent physical entities on a map and its length can be considered as the proper distance of a road. This subset is used in some experiments of this dissertation to define the location of main collection points or nodes. Aiming to serve the same number of cells for each collection node, the cells centroid will be connected to a collection point via the shortest path.

Overview The current condition of urban patch in Almeria region has been analysed, the grey colour defined as greenhouse, and the black colour defined as other function such as housing, retail shop, office and university. As shown in the picture, greenhouse function is occupying almost 90% of the site, this condition need to be analysed and evaluated to know either the current condition has possibility to become more effective and useable in terms of function, condition, quality, effectiveness and also take into consideration that this patch will be used for living territories in the future time.

70

The analysis will evaluate the condition of current network connectivity and the result will be compared with the developed cities in Mediterranean region, because as mentioned before that this area will accommodate population in the future, which mean that it need to meet the standard for people to life in good condition there. This analysis also evaluated the public space quality and behaviour. Considering that right now public space in greenhouse patch in Almeria doesn’t exist, by using the result from this experiment, the right place to put the public space will be able to evaluate.

Connectivity

Agent base analysis

The image shown in the evaluation later is depicts the “connectivity” value of the “Euclidean Maze,” in the form of a heat map. Red patches in the maze have a greater number of immediately connected spaces (convex partitions) than blue patches (i.e. red areas are more connected to the rest of the maze than blue areas).

An agent-based model is a simulation of individual movement behaviour in which ‘agents’ choose their direction of movement based on a defined visual field derived from visibility graph analysis, in which agents have access to pre-computed information about what is visible from any given location in the map.

Measure to indicates level of visual connectivity as the most visual space shown in red colour. Different function required different connectivity condition.

The agent-based model allows the programmer to simulate the likely behaviour of people as they navigate through the environment. The agent moves using the random next step rule. Each grid square is incremented every time an agent steps on it.

Greenhouses area, Almeria Connectivity The result from connectivity analysis of Almeria greenhouse morphology shows that network on site is in good condition in terms of connectivity. However it is not well organized and also doesn’t have hierarchy.

High Connectivity

Even though most of the networks are covered with green colour, but the blue colour at some road show that it is not accessible for logistic function because the roads are to narrow. The street width need to be increased for better logistic requirement. Low Connectivity

Agent base Analysis The result from agent base analysis show 30% of green colour cover the area which means it has potential to turn become public space or facilities and amenities. However because the greenhouse area was not planned before, the growth of the greenhouse caused inefficient network development (showed in blue colour).

High Activity

This inefficient and unplanned network should be modified to accommodate additional function such as living space, tourism attraction, amenities, and etc. Low Activity

71


Madrid, Spain Connectivity High Connectivity

The result from connectivity analysis for the network in Madrid shows it has very integrated network and also well organized in terms of hierarchy. Main road has high connectivity which showed in green colour, this network also connecting square which also function as public space. The network in Madrid has characteristic which create sequence of some narrow street will meet at some point, and later on this point become public space.

Low Connectivity

Agent base Analysis High Activity

The result from agent base analysis defined which network has high activities and also defined the most crowded area. An ideal planned, the most crowded and busy area should be where the store and commercial functions are located. As expected, the result from the analysis is match with the current existing condition, the network that covered by green colour is where the stores, amenities, and public facilities are located in Madrid. By placing the public space in the busy area, it able to increase the quality of the adjacent condition.

Low Activity

72

INHABITABLE PRODUCTIVE LAND Emergent Technologies and Design


Rome, Italy Connectivity The result from connectivity analysis for the network in Rome shows that even though the roads are very wide but it doesn’t provide better connectivity.

High Connectivity

This condition is because some of the road in Rome have dead end, not connected to the other road. Increasing the road width is not the effective solution to increase the connectivity for the network. However because Rome is a grid planned city, which make the public space is still well connected. Low Connectivity

Agent base Analysis Considering Rome as a grid planned city, the result from agent base analysis showing an equally distributed public activities. The public space and road in Rome has the similar crowded and activities frequent almost in every part, the hierarchy can be categorize as the same for all without defining the main functionality and purposed.

High Activity

This can be good proposal if the function of urban patch is singular, however if the function are more than one, the network need to be clarified in terms of hierarchy. Low Activity

Conclusion Many major cities in the world offer high quality urban space due to sufficient amount of public space per person. However, not only that ratio makes the public space better but also the walking distance to a public square or park. Any residential unit should have a maximum limit of walking distance to a public park which can vary from a small pocket park in the corner of the block to a large public park. After the analysis of public spaces in Madrid and Rome, while having a different area of public space compare to each other, still the area within a walking distance from them is approximately the same; 770,000 m2. Having different population density, 5304 people/km2 for Madrid and 2,232 people/km2 for Rome, it has been observed that the total area of public parks rises in relation to population density number. On the other side, Almeria greenhouse area is not a high density patch. However, it has a sufficient amount of open public spaces for that particular area. By having the population density at 150 people/km2 the ratio of public space per person rose steeply to 182 m2/person. This figure is far behind a proper urban desired value therefore the population could be much higher. To conclude, Although having such a decent ratio of public space per person in the example of Madrid and Rome the urban quality should also be achieved by a integrated and connected distribution of public spaces reachable for every resident in the site. Further step will be to measure the quality of public space in terms of temperature for this particular climate area by quantifying amount of sunlight hour per day and radiation of the enclosing faรงades.

Conclusion Analysing the differences between major cities in Mediterranean such as Madrid or Rome and comparing these with the existed “Greenhouses city� fabric in Almeria, it has been observed that due to hot and arid area of the Mediterranean, for people to live in liveable condition the urban patch needs shading. In the building itself if there are sufficient thickness of wall or has eaves, people are able to gain comfort condition. However, on the public area outside buildings the control of shading is achieved by appropriate streets widths and buildings heights. Building height is one of the elements that have a relevant effect to the public space. The heights have a direct influence on streets shading. From the Arabic influence, streets N-S are wider street than those with E-W orientation since the buildings beside can block the sunlight through out the day except at noon. E-W street may need narrower street since it may not benefit from building much. After analysing, one thing should be mentioned is that Rome and Madrid have the same average height of building at approximately 25 metres height, according to Google Earth data, and in the Almeria greenhouses area, the height is around 3 metres. By that circumstance, the street exposed area in both cities is almost the same. In Almeria’s greenhouses, it raised to 61 %. Also by having greenhouses on ground level, the Polyethylene plastic reflects sun light and, in summer, when the temperature in greenhouse rises up to 50oc, the heat can transfer from greenhouses to outside area which will be explained further in the next chapter.

INHABITABLE PRODUCTIVE LAND Emergent Technologies and Design

The greenhouse in Almeria mostly used polyethylene as the building envelope. The climate in Almeria mostly has temperature between 8oC to 42oC. The ideal scenario will be to keep the temperature inside the greenhouse 27oC. In winter season, greenhouse in Almeria still able to produce food because the temperature does not drop insignificantly. However, during the summer season there is an issue needed to be tackle. Eventhough introducing ventilation system probably modulated temperature, it will not drastically changed. Therefore in Almeria, during summer season, the greenhouse will be emptied, which mean no cropping times. This condition is seen as potential for the public space to accommodate the greenhouse area during summer.

As the result of the calculation, we manage to calculate the temperature change that caused by 2 causes of energy transfer. The highest is at July (summer) because the energy from solar radiation contributed huge amount of energy, however during summer season there is no cultivation inside the greenhouse. By comparing and evaluating these 3 distinct morphologies, some relation are conclude.

Overview Traditional Typologies

Material Studies

Investigating traditional type of building in this particular area is to be used in this project as the base for optimized proposed typologies. The study of existing ones will feed the new designs revealing important concepts that have been developed throughout time.

Although in urban design, concerning about material behaviour or aggregation seems irrelevant. However, in some circumstances, it can contribute the system. By knowing the properties of material used, several integration logics may be specified in relation to material chosen.

Integration Techniques

Overall Tactical Opportunities

There are several tactics to combine greenhouse with habitation units. One is Juxtaposition where two things are placed together with contrasting effect. Hybridisation is another method where some areas are turned into different functions creating a hybrid area. Embedded and Attached are other potential integration techniques that offer potential to be explored further.

By investigating all these introduced aspects, the developing typologies that meet the requirement of having productive area and inhabitable area would be broadened. Bearing in mind such aspects will also benefit to further scale where tackling network or urban space.

Aggregation Logic By exploring the different logic of aggregation a wide variety of spatial combinations is achieved using the same built up area and volume. For instance, if stacking the unit as a stair instead of stacking vertically, bigger surface area could be dedicated to greenhouse use while creating shadow for the residential part. Different orientations can either offer or decrease a suitable area for placing greenhouses. Differently orientated block would create different spaces and provide varied solutions in combination with adjacent buildings.

Mediterranean Building Typologies Traditional architecture is essential to be investigated and analyse as it is an collective knowledge through generation of designing. From earth material to concrete, people in different places learnt the idea throughout experimented where the benefits will be kept and the drawbacks of existed generation will be abandon for next generations. It is crucial step not to start from bottom but to gain the true generational design to run a genetic algorithm. The result were aimed to get directions for designer who understand Mediterranean condition and able to design further.

Image3. Alhambra city Source: Writers

As in Mediterranean, there are several types of building clusters. Take a look at building cluster from Greece, it showed that there are groups of building clustered around the shore area and as the shores are mountain, the buildings were built as step to get from below to the peak of the mountain while in Morocco, it can be noticed that most of the traditional buildings were made from earth material where it is convenient to get and provides a suitable thermal comfort where the building has less perforation or opening and has ventilation through series of building placed in unaligned grid. In Spain, probably the most famous Cerda’s building block in Barcelona has been widely took into consideration because of its emerged behaviour from the primitive block that is manageable to study and it is worth to investigated further to develop the system .

Two critical season that affected living condition in this particular area are Winter and Summer in which winter, the temperature can go down to 5-8 oc. However in Summer, the temperature can raise up to 35-42 oc. Take a look at Habitation area, it needs shading or cooling device in summer time while in winter, the temperature inside is warm but in some months it could be cold and people who live inside need heating device to constrain the comfort temperature. On the other hand, Greenhouse need to constrain temperature from 20-27 oc to able to cultivate which mean in every season, plants can be cultivated except in summer where the temperature in greenhouse can climb up to 40-50 oc. This season there is no cultivation and the greenhouse has been left over.

Criteria:

Criteria for integration has been set for finding the suitable solution of mixing greenhouse and habitation area together. Firstly, In winter season, Greenhouse needed to be heat generator for habitation area. By knowing that in greenhouse, the temperature will be more than temperature outside, it has more benefit to release the heat to residential area than release it to where else. While in Summer, knowing the typical material used for greenhouse surface in Mediterranean helps to indicate that by using white-semitransparent Polyethylene, it can help for shading the residential area while ventilation needed to be applied in summer to allow hot air inside greenhouse area to release to the air and keep only shading benefit for residential area.

These 3 types have same characteristic, they all have public space in the inner part that can be used by the inhabitant but also can be turned to become urban space. This phenomena is very common in Mediterranean region culture, when small square is connected by narrow street with other small square, it becomes public space able to increase the quality of adjacent environment. Inspired from the Mediterranean culture behavior, the project sees potentials to turn this semi-public space to be the basis of Inhabitable Productive Land project. Based on the previous research, if some areas want to become productive land, it needs to receive sunlight at least 5-6 hours/ day. The step is introduced. By simply changing the level of the ground, the shading is able to be manipulated. Using this integration strategy, the area which is shaded by the building or unproductive area, will be able to be modified and turned into productive area that receives sunlight more than 5 hours a day.

Take into consideration that the plot size is always 72mx72m, therefore 2 staggered logics are introduced: 1. If the building height is less than 6 meters, the productive area can be placed on the roof because it still has 1:12 incline ratio, acceptable for circulation and water irrigation. 2. If the building height is higher than 6 meters, the productive area just occupy the steps and ground area.

Conclusion Based on the evaluation from solar analysis, it show promising result that the staggered step integration strategy has potential to increase the production rates with more than two times from the current condition (without staggered step). Staggered step strategy works guide : 1. The system will evaluate which ground area has shadow cast that caused by the building. 2. The shaded area (unproductive area) will be subdivide based on how many sunlight hours it received per day. 3. Then the subdivison surface will be moved vertically within range of (0.1 m - 1m) to gain sunlight more than 5 hours to become productive 4. The vertical movement should me within the incline ratio (1:12) in order to be able to be cultivated and access by farmer. As the result, almost all the potential ground area become productive land that received sunlight more than 6 hours. However the second strategy, which is using different plant size according to the height of the plant. This strategy will allow every plant to gain sunlight without changing the ground condition, the benefit of this strategy is in summer season, the X-Large plant able to create shading for surrounding building.

INHABITABLEPRODUCTIVE NETWORK

Network Analysis |

Connecting Urban and Agriculture Territory

Figure1. Existing Network Source : Writers

Overview

Conclusion

Analysing the existing network One of the first objectives in this project was to improve the current situation in the unidentified territory, which is left between urban and rural areas in Mediterranean cities. To do this, an integration analysis has been done on the existing networks. The red colour shows the integration of a line in network. Therefore, the more blue the line the less integrated in the whole system. The analysis has shown how there is no connection between rural and urban areas. This fact, together with the lack of different uses apart from residential, creates not only connectivity issues but also social and economical problems as mentioned in the Urban Borders exploration at the chapter of case studies. It should be highlighted how the basic addition of a line bridging the gap through the patch modifies the entire network even in the farthest nodes.

102 INHABITABLE PRODUCTIVE LAND

Emergent Technologies and Design

From a set of different proposed options of networks through the patch, the most effective as well as the shortest part of network is chosen to be the primary network in the new inhabitable and productive patch. As main criteria for developing further one of these results has been the most improvement done on the existing networks with the shortest overall distance within the new patch. After carrying out this studies has been observed how part of the existing network within the patch does actually improve and makes a clear contribution to connection urban-rural. Furthermore, using some of the existing roads will improve the connection between the new patch and the existing zones. Due to that fact the decision of keeping one current road has been taken and this road has been turned into the main artery of the new inhabitable.

Overview As explained in the analysis of public space chapter, the streets width has an important effect on the quality of the public spaces and streets. This, together with the buildings height will be the parameter to make shaded areas on the street, so necessary on these places.

Conclusion An important design decision taken in this project has been to rotate the grid 45o. By doing this, two problems are solved at different scales; firstly, the self-shading of the buildings in clusters, this would reduce the productive area if they were on a northsouth orientation. Secondly, at an urban scale, deals with the shading on the roads, in this case the shaded area is maximized as wanted. The experiments on this chapter show how the shaded area is way bigger when the grid is rotated than in that orthogonal and purely north-south and east-west orientated.

Overview Once these existing roads are maintained for the new development one of these roads is considered as the main artery within the new patch. This road does not follow the grid orientation and distribute the rest of the primary network in a branching pattern. This artery will also host the collection points for production. For the rest of the network levels, a grid is plotted on the site, based on the cell dimension 150x150m. Cells are separated creating streets that could be 12m or 6m wide. The 12m streets will be the ones dedicated to the production transport and will connect the cells to the collection points. This level of the network tend to cover the most area possible on site, meaning that all the cells should have at least one side facing this road. The rest of the streets are 6m wide which determined as urban network and also will be related to pedestrian use. Introducing the gaps between building in clusters are also 6m wide. This network will be able to access by pedestrian and also allow to use chart and trolley in terms of transporting products.

Network that has hierarchy order will be able to perform effectively and also optimum. Considering the site will be accommodated with 2 different functions. The hierarchy of the network is created based on the function requirement. The artery network which will accommodate large lorry and refrigerate truck needs the widest dimension 18m. The productive network which will be used for transporting products from every cell to collection points, will have 12m wide. The last one is urban network, which will be used for urban transport and circulation, in order to provide good quality for pedestrian, this network need to be shaded on partial part, 6m road wide is difined as the result.

DESIGN DEVELOPMENT On the basis of data and strategy which were obtained from research experiments, the design strategy able to be developed further. The priority of this stage is to set up the base for design proposal such as : proposing an integrated system from the combination of urban and agriculture, developing network which functioned for both urban and agriculture needs, population and production distribution strategy which has most benefits, and also the plot subdivision creation. All of these developments are evaluated and analysed in sequence to provide symbiotic relation.

System Application | Image1. Site in Almeria Source: Google Earth

Mediterranean basin region has specific conditions in terms of sun light hours, temperature average, rain regime and has been chosen to be the site application for the system. Among the Mediterranean cities, the southern Spanish city of Almeria is of interest due to the fact that hosts the largest concentration of greenhouses in the world, on an infertile soil, desertification issues and extreme climate. The current situation of this area has been analysed and prospective figures have been estimated according to future expectations and own ambitions. Furthermore, as it happens in many Mediterranean cities, there is a presence of an unidentified territory between the urban and rural area without any particular use. This fact creates network and urban problems at this peri-urban area and adjacent areas. The location of the chosen site is of particular interest due to the sea next to one side.

Cluster aggregation is created from aggregation of four building that are extracted from the building integration experiment. Using the best result, building which the highest productive area, is chosen from previous experiment to form a cluster of four buildings. The building clustering method is also inspired from the typology of Mediterranean cluster that has common public space on the ground that is articulated with several narrow streets. These narrow streets will be perfectly shaded because it is surrounded by buildings of 2, 3 or 4 floors. This condition is really common in Mediterranean situation. As explained before, this region is exposed to an extreme climate where the temperature during summer season is very high. It needs shaded street and public space. In contrast for the inhabitable productive land, it needs to maximize the production area by exposing the ground to the sun. However by clustering 4 building, the production rates have decreased because it creates self-shading from one building to other building. Therefore new modification rule rotation is introduced to optimize the production rates. The optimization logic will make each building able to rotate inside the cell with different degrees 90,180 or 270.

As the result 765 combinations were created. This experiment also used sunlight vector of Almeria Latitude Longitude 36.8403oN, 2.4681oW. The calculations were run at winter season from 9.00 am – 18.00 pm, means the calculation using the least sunlight hours in entire year. Surfaces that are hit by sunlight more than 6 hours were considered as potential area to become productive land. Surfaces that have sunlight hours less than 6 will be used for public space. This result then defined the cell type which will be used as the Inhabitable Productive System, which applicable to be tested in the Mediterranean basin region which has high sunlight hours. Followed are 9 cell identity condition. 1A (high population , high production) 1B (high population, medium production) 1C (high population, low production) 2A (medium population, high production) 2B (medium population, medium production) 2C (medium population, low production) 3A (low population, high production) 3B (low population, medium production) 3C (low population, low production)

Conclusion Having two objectives lead the aggregation to 9 different variation types. Types which combined high, medium and low in terms of population and production. The result from the sunlight optimization shows that the building type which has higher number of floors, also means higher population will have less production area because most of the areas are covered by shadow. On the other side, the building with just 2 floors, which means low population, will have the highest production rates because it has less shaded area and also the roof top from the building will be able to be occupied by productive land. In general the result shows that the building with south facing stepped slope has the highest surface area affected by sunlight. On the other hand when the building has slope facing north, it has the lowest sunlight affected surface. The building that has slope facing east and west also has contribution for the productive area. The optimization progress tends to rotate the building orientation to the north and middle of the cluster to allow the sun reaches ground floor area and create higher shaded area for public space, i.e. streets. The result of this combination is then placed on the desired site according to the network. The overall population and production will be achieved by changing the total amount of cell from different variation condition. For example, by simply increasing the number of cells that has high population, the system will increase the total population number. On the other hand by adding more cell that has high production rates, the system will increase the overall production rates.

Overview Cells distribution is generated as the result of overlaying the distribution from population and production distribution gradient. Since this project is dealing with integration of two different functions, it is also necessary to specify the importance of the products management. Once the urban network has already begun to be developed. The local production requires places where products are stored, prepared and distributed. After studied the existing cooperatives and preparation centers, it is necessary to have at least two collection points to serve the proposed site area. These 2 collection points are located on the main artery, in a reachable place to avoid future logistics issues. By managing the influenced distance from the defined attractor line and points, the distribution of cell types is controlled. In this case, using the distances influence from the peri urban border line and those others from the collection points. Density Distribution Through the previous population growth, the starting point will be the peri-urban area, it grows to the rural area where the available spaces are located. Therefore, the distribution will be started from the previous peri urban border and also both of the collection points as the attractors, the area where the highest population cell will be located. Production Distribution As for the production area distribution, the cell with the highest production rates will be placed close to the collection points due to the logistics purposes. These cells with highest production rates also will be placed along the border of agriculture territory considering the growth tend to start from the previous area.

Conclusion The system application at the global scale is a 2 layers system as mentioned before, merging production and population gradient, the cell identity content is found. By managing the influenced distances from the attractor lines and points, the distribution of cell types is controlled. In this case, the distance influenced that has been used for both population and production rates distribution are : High Population Cells and High Production Cells are distributed within the distance less than 300 m from attractor line and points. Medium Population Cells and and Medium Production Cells are distributed within the distance range from 300 to 600 m from the attractor line and points And Low Population Cells and Low Production Cells are distributed at the range further than 600m from attractor line and points. By using this influenced distance the total production and population meets the target number that has been set on previously.

Overview As the result from the design experiment chapter, the first stage of new networks creation in the proposed patch was created. This first stage contains some new network that afterward will become the base guideline for the network development in the proposed patch. The new networks from the first stage are lines that connect urban territory and agriculture territory directly from side to side. These additional networks were proved and the increase on the quality, connectivity and integration of adjacent existing network has been observed. During this stage, the existing network alongside the river path has potential to be re-functioned as the main artery of the network. This first stage development also divides the patch in 9 subdivisions which lead to the positioning of 2 collection points that have been mentioned in the distribution development. These 2 collection points will be placed on the side of the artery network. Using the additional networks which connected urban and agriculture and also using the existing network a long side the river bed to be the primary network, makes the adjacent existing network becomes more integrated. However the site still requires a larger network in order to fulfil the determined function which are to become proper inhabitable place and also productive area that works alongside the logistic purposes.

Productive Network According to the network experiment, the diagonal grid has some benefits in terms of providing the needs from determined function. Therefore the productive networks appeared as diagonal lines which are connecting perimeter border with artery network and collection points, this is due to the purpose of transporting products from every cells to the determined places. Due to the requirement of the specific needs, this productive network will be 12 meters wide road. These productive networks also become the parameter to control the positioning of production field. Therefore all the productive area within the buildings will be facing this network.

Urban Network The same as the productive networks, urban network also appeared as diagonal lines. In order to match the system with the site, the plots should have dimension not smaller than the cells size, which is 150mx150m. In the next development, the cell will be modified accordingly to the site condition and other objective such as important junction, public amenities placement, and other functions.

Resulting Network development on the site

The analysis of the existing network using Space Syntax has shown that, the current condition of the existing network demonstrated a lot of blue colour which means it is not well integrated between urban territory on one side with the agriculture territory on the other side, and some of the roads, i.e. the one alongside the river bed, are showing blue colour because it just has intersection on the north and south part, no connection in the middle part.

After the new networks were introduced then the analysis is run again.

The purpose of this network development is to integrate 2 distinct territories and bridge the gap territory to be inhabitable and productive in proper conditions.

Emergent Technologies and Design

The result from the analysis shows that with the new network, the two distinct territories become more integrated, and also this networks make the adjacent network perform better in terms of connectivity and accessibility.


Conclusion Using the result from the network experiment, the network development stage was carried out. The most efficient way to connect the urban with agriculture territory is by introducing bridges like network that go along from east to west. The network development also takes into consideration the current existing network with the aim to provide integrated network between 2 territories. The preferred method is connecting the discontinued road ending in the site from both territories, with just introducing small changes and modification, so that the overall network becomes more integrated. The network hierarchy is also introduced to determine which network is related to which function, this hierarchy does not only provide more organized network but also it is able to increase the public quality. The 6m wide roads network will be shaded during the daytime. This condition is needed for Mediterranean area. On the other hand the productive network is 12m wide, this width will allow the logistic requirement to function effectively. The main artery is 18m wide. The reason for this number is again due to logistic efficiency plus the possibility to be used as space for pedestrian also. Managing the hierarchy of the road by changing the width of the road, the system seems to have potential benefits.

Overview The subdivision of the plot is corresponded to the network development. It appeared in the same time whenever the network is created. Therefore when the first stage of network development was created, the first plot subdivision also created. The artery network along the riverside, divide the site become east and west area, and the bridge like network divide the site horizontally. The subdivision on the most south will be used to place the public amenities function because it has direct access to the sea side and also it has the existing network that connect urban and agriculture territory.

Preliminary Diagonal Grid According to the research and case studies from Mediterranean basin region, the most suitable planning for the urban tissue to work efficiently and beneficially will be grid planned city. However with the parallel grid plan, it will cause problems for some of the networks especially the horizontal because it will be fully exposed to the sun orientation, therefore rotating the grid 45 degrees will allow the network to be partially shaded which is needed for improving public quality and also the most important 2A 2A 2A 1A 2A thing is, this diagonal arrangement will allow the sunlight to hit 1A 1A 1A 1A 1A the ground more efficiently which also mean the productive area 1A 1A 1A 1A will increased. 1B 2A1B 2A 1A1A 1A 1A 1A 1A 1B 2A 2A 2A 2A 2B 1C 2B 1C 2A 2B 2A 1C 2B 1C 2A 2B 2A 2C 2B 2C 1C 3A 1C 2B 3A 2B 3A 1C 3A 1C 1C 3B 1C 2C 3B 1C 2C 1C 3A 2B 3A 1C 2B 3A 3A 2C1C 2C3B 2A 1C 3B 2A 1C 2B 1C 2B 1C 2A 1C 2A 2B 1C 2B 2B 2B 2B 2A 1C 2A 2B 2B 2B1C 2B 2B 2A 1C 1A 2A 1C 1B 1A 1A 1A 1B 1A 1A 2B 2B 2A 1B 1A 2A 1B 1A 1A 1B 2A 1A 1A 2A 1C 2B 1B 1A 1A 1A 1C 2B 2A 2B 2A 2B 2B 1B 3A 2B 2B 1B 3A 2B 2B 1C 2C 2B 2B 3A 1C 2C 2B 3A 1C 3C 3B 2C1C 3C 3A 3B 2C 3B 2C 3A 3B 2C 3B 3C 2C 3B3B 3C 2C 3B 3B 3C 3B 3C 3B 3C

This diagonal grid with the size of 150m x 150m (following the cell cluster size) will not directly become the network or plot subdivision, but this diagonal grid will become imaginary line to help the next stage of network development.

The next subdivision is caused by the productive network development.

Following the sequence from network development, the urban network creation will be the next development.

The main idea of this subdivision step is to create access that able to serve every cell on the site, Diagonal lines which connect the perimeter line of the site with the nodes on the artery network were appeared as the productive network.

This urban network will divide the plot by following the imaginary diagonal grid, this subdivision also become the final subdivision for the plot development, because the plot size in this stage will be around 150mx150m of even smaller.

This diagonal line is overlaying the imaginary diagonal grid as the guideline. This subdivision stage is mostly divide the plot become triangular shapes, and also with this subdivision will allow every cell to have access to the artery network.

If the plot size is to small, the cell will not fit inside some of the plots that has smaller dimension than cell size. Therefore, the plot subdivision need to have the next development to prevent the plot size becomes to small.

Plot Merging and Identity Definition

Conclusion

Merging between two plot or three plot was introduce in the final stage in order to prevent having a very small plot subdivision.

The Plot development has direct relation with the network development. For instance, every time the network was created, the plot will be subdivided accordingly.

The merging rule was set, whenever the plot has total area smaller than 50% of cell dimension (150mx150m), the plot will merge to the neighbouring plot which also has area smaller than 150mx150m. Using this final modification, the final plot was created. As soon as the final plot subdivision was created, the cell identity will be able to be applied inside every plot.

The plot subdivision is also developing in the same time with the network development from the very first stage. However after the urban network creation, the plot development will be the one who controlled the next overall development. This development stage is when the plot started to merge if it has size smaller than 50% of cell size (150mx150m), it will prevent from having very small plot size and also this merging behaviour able to reduce the problem that appear in the intersection node from some network. After the final plot is created, the cell identity ready to be placed in the determined location based on the previous distribution development.

Shows by orange to red colour, It can be noticed that with the stepping strategy, the area assigned to be an agriculture land has become more productive with sun light exposed to such areas more than 5 hours. Habitation areas also benefit from steps in which it could get warm temperature from greenhouses temperature during winter season.

DESIGN PROPOSAL The design proposal is appeared as the result from integrating the most potential possibility and tangible result from design development stage into the desired site which is Almeria. In this stage, small changes to optimized the overall performance were introduced and also to provide more articulated final design plan. Emerging behaviour can be seen in this stage, some of the locations such as productive intersection, urban intersection, high populated cell appeared to have different condition between each other. The more detailed visualisation will be show in this stage.

As in urban scale, the experiment take place in order to distribute the clustered blocks to get the achievement goal of number. In design proposal regional patch has been sectioned to be the area investigated. The section area has been chosen as it is the most congested area with main collection point node and the variation of building block can been seen.

Regional Scale Evaluation Our proposed system aim to integrate the function of agriculture and habitation area. Compare with other existed projects where usually dealt with high density area consequently the vertical building emerged as self sufficient building. This project dissimilarly tackle the low density area of Almeria city where there is greenhouses expansion issue happening and the unidentified land in between has been experimented. The area on top of the picture is the area that connected to existing urban area of Almeria city where people tend to migrate from the city centre to this area. As a consequence, the area next to it is predicted to be dense where it still allow greenhouses to integrate with in the block. Contradictorily, The area on the bottom of the picture shows the existing areen houses area in which the area next to it tend to have building blocks emerged to the greenhouses. Noticeably, building block in that area has low number of storeys(2-3 storeys) with the 2-storeys block the greenhouse area capable to climb up to the top of the building due to applicable incline.

Collection Point With in the tested site, There are two main collection points emerged by the mean of number require per production area. The collection point will be used as the main node where all the networks are easily connected to these area. Collection point as mentioned in typologies section, does not require high ceiling (Approximately 4-6 m) and require few amount of natural light because it mend to be the place where it can stock the product for long time and sun light could harm those products. In the design, collection points has been

153


2-storey blocks The 2-storey blocks can be used as public space when there is no cultivation season. However, when the cultivation season occurs, it can be use as a base for greenhouse where the step has already optimise the area of the block to become a productive greenhouse area. This particular type of building blocks has the height of 6 m in which the step can benefit the top floor of the building to become a cultivation area likewise the courtyard area.

3 & 4- storey blocks Correspondingly, 3&4-storey blocks has the same logic of 2-storey block where the steps benefit the area to become productive. Nonetheless, the steps may not climb to the roof top of the building block because basically it is too high. However, the step help the greenhouse quality and greenhouse when it attach to one side of the building, it also modulate the temperature in both winter and summer season for the building block to become more comfortable.

Stepping Strategy The Primary strategy is the stepping strategy where the step inclined the cultivation area to get the acceptable amount of sun light without light interception from the building itself. Steps also contribute the building where it can be use as a public terrace in which it is still the conceptual idea that could be investigate and experimented in further development.

156 INHABITABLE PRODUCTIVE LAND

Plant variation Strategy In some area, where stepping strategy could not be introduced to the building in some circumstance, Plant variation strategy was introduced to tackle that issue where it still gain the acceptable amount of sun light as trees and plant will be placed correspondingly to sun exposed. One thing to point out is plant use their leave to photosynthesis, as a consequence, the plant variation strategy is valid.

157


Greenhouses usage in cultivation season Most of the year greenhouses will be use as usual, to be a cultivation land. It mostly use for commercial purposed where it designed for easily collect the products to the collection point ready to be exported. In this season, greenhouses will be closed with few amount of ventilation voids as typical passive greenhouses in Mediterranean area.

159


Greenhouses usage in summer season In contrast, when there is summer season. Plants can not be grown due to high temperature when greenhouse was closed. However, by open up the greenhouse side facade and introduce ventilation on the roof of the greenhouse, the temperature decreased. Also, greenhouses in this particular area use diffuse polypropylene . By that circumstance, the translucent surface filter short radiation UV and the high temperature could be spread out by such opening introduced where it will be investigated further development.

Conclusion As a conclusion, the system developed throughout this dissertation tackles complex urban issues at a global scale as well as tend to deal with architectural symbiosis between two quite different functions. Therefore it faces a wide range of problems at different scales. The experiments carried out to inform all these designs have been a crucial element during the process, without them there would have been almost impossible to take such relevant design decisions as seen throughout this presentation. The authors also consider that a wider range of experiments would improve in an important manner the result of this design project. These to-do experiments could be related to the creation of networks and its evaluation in a deeper way, making use of others computational techniques.

The focus now is going to a more profound level into the architectural scale and the clear resolution of the integration greenhouse-residential uses. The concept of using existing greenhouses cover material has been chosen but deeper investigation must take place to verify the hypothesis of multi-use area between greenhouses and public space. Moreover, increasing number of unit that can be benefit from greenhouse temperature must be take forward in relation with differentiation of units. At the same time another scope is put on a more detailed combination of public spaces, roads, and amenities to adjust and refine this new inhabitable and productive settlement as our little contribution for more sustainable and responsible future cities design systems.

It has been observed that integrating the 2 distinct functions is not the only way to create decent territory for people to live. In addition to that, by introducing highly integrated network and providing public facilities and amenities on the appropriate locations would increase the quality of the urban space. In certain parts, the system integration needs to be investigated in terms of mutability and more flexibility.
