2 persons per second move into cities every day, an estimated of 180,000 (one hundred and eighty thousand) per day. By 2030, the world’s population is expected to be 8.6 billion people, with 3 billion of them living in cities of at least 1 million inhabitants. This projected urban expansion will result in 5% reduction of rural land in Europe. 60% of the world population would live in an urban area by 2030, from which the 15% would live in the projected 41 megacities (defined as the cities with more than 10 million inhabitants) and they are. Studies have shown that due to human activities, density and construction materials, cities are, on average, 5 to 10 degrees warmer than their surrounding landscapes. With this in mind, the projected increase of megacities means an increase in global heat flux. The zones where the megacities are projected to be will face, a bigger increase of heat (translated to an increase in temperature, greenhouse gases and global warming). *M a p ela borate d by Ni c k y H oln e ss for th e te a m

In UK , there are 5 prevalent winds from different points of the island. The most prevailing ones are the winds coming from south west. This tropical winds goes through the lowlands, territories in which temperature is higher than in highlands (coloured red in the map). Higher temperatures can decrease wind speed. That is why the south east and west part of UK is less windy than the rest of the country. As it is showed, all the main cities in UK are located in depression lands where temperatures makes the wind speed lower. Most of the population lives in the east coast protected from the wind, and the lower wind is located in London. Warmer land with less wind means also climates with less rain fall. This weather different from the rest of the island is the one we use for landscapes studies. *G raphic by Ju a n Pa blo D e lla M a g gi ora for th e te a m

The city of London, can be analyzed by materials classified by their absorption or reflection capacity. These conditions, including infrastructures and programs that generate and emit heat, allow us to classify the activities inside the hot pockets of the greenbelt. We catalog them by general categories depending on the principal behavior of the present materials and activities, and the overall dome created.

HOT SPHERE WIND CONDITION
The urban heat dome has a very scientific measurement, which is related to the heat flux, area and diameter of the area or emitting entity. The domes generated by the hot pockets inside the greenbelts can give us an anthropogenic topography of microclimates that may shape our landscape. It is important to mention the fact that the dome can experience a deformation because of the wind that is how we are relating the two systems. *G ra phic by Ju a n Pa blo D ella M ag giora a nd Nick y Holnes s
CELLPHONE WITH INFRARED CAMERA
To understand heat and wind behaviour and their relation with material heat storage a physical experiment is created. The objective is to understand how heat moves beyond emitting objects through the air. Using an infrared camera, several compositions of hot and cold clay and concrete emitting pieces where registered as a library of conditions to understand heat phenomena. A wind source was also used. Finally we understood that heat can be controlled to move through the space using cold to transfer energy from one place to another. *Ex p er iment by Ju an Pa blo D ella M ag giora for the team

We are studying the heat and not the temperature, because the air temperature is just a measurement of the average internal kinetic energy of air molecules, but heat refers to the energy stored in an object. Through movement of the molecules we can increase the temperature.

Our objective is to create or mitigate heat and/or wind in the hot pockets inside the greenbelt, in order to produce diverse microclimates and enhance activities within the zone. A new landscape generated from the urban heat island that can connect or separate activities and produce new relationships and synergies between apparently diverse programs and ecologies.

As our cities continue In this way, there is an opportunity for long-term design thinking, as the phenomenon will continue, and increase, through the years. There are several opinions and facts that may be discussed as good or bad, but is hard to classify these effects with only one tag because there are opportunities of design in each of them, as we can mention the increase of rainfall downwind, the reduction in the range of freezing temperatures, drier landscape and much more.

As we mentioned before, we took two sample sites to experiment. The first one is the King George V water reservoir, located north-west to the city. This place is particularly interesting because water is a cooling material, but we find this big heat generating area just beside. And also, it a popular place for birdwatchers because of the migrations during summer. We made some interactions to analyze which is the behavior of the different domes when we increase or decrease heat and cold. *Exper ime nt by Ni c k y H oln e ss for th e te a m

We are looking for the isotherms and their behavior with the wind. We explore different patterns with cement and clay, several positions and temperatures. The first approach was done with simple geometries and arrangements to understand the behavior on the isotherms, then we add complexity by building a bigger model. This exploration gave us a result we can translate to urban scale and the heat domes. They merge between each other, but what actually gives the shape are the cold objects, guiding heat in certain direction. The systems fight to find the balance of temperature by losing it always from the hot to the cold one (2nd law of thermodynamics). *Exper ime nt by Ni c k y H oln e ss for th e te a m

The second sample site is the Heathrow airport, known as the second busiest airport in the world. It is located 23 km to the west from central London. It also has water bodies very near, but in a different composition. Contrary to what is happening in the King George V reservoir, the water bodies do not have a heat point before the wind, so they mitigate in a better way the heat produced in the airport, deforming the dome.

The domes can merge, as we saw in our physical experiment, but never completely losing their shape. They share and interact energy, this applies to the cold and the hot ones. With the explorations of increasing or decreasing heat, we can build a topography from the isotherms the dome is giving, allowing us to reshape and manage the heat flux, which would also affect wind patterns in the zone. The increase of heat may increase the temperature creating different wind patterns (it can also be created through the increase of radiation to create low or high pressure areas, wind always go from high to low pressure). *Exper ime nt by Ni c k y H oln e ss for th e te a m

The experiment aimed to explore la interactions between energy. We interpreted the cooling bodies as isotherms in downward direction, below the ground level. While the hot bodies or infrastructures as isotherms above ground. These two opposite interpretations allowed us to build a topography from the isotherms coming from the activities existing in ground. The aproximations respond to variations in land use as well as densifying the heat in some point to exagerate the results, having a benefit to harvest all the energy that has been increased.

The energy transfer is never done from black to white, it always behave as a gradient, as Phillipe Rahm explains. Processes that are not defined by a line but by a range. Our second exploration allow us to see these interactions and gradients the domes face during the thermodynamic events. The lines never remain the same as this is a dynamic phenomenon that may never repeat the same pattern. As the cities and modern life is an intense life, as the French philosopher Tristan Garcia explains, we reshape this landscape with a variation of intensities, through the material gradient property. The phenomenon that is not treated as good or bad but as an opportunity to design through the gradient. *Exper i m e nt by Nick y H o l n e s s fo r th e te a m

The second law of thermodynamics states that heat does not flow spontaneously from a colder region to a hotter region, or, equivalentl, systems tend toward an equilibrium state in which entropy is at a maximum. This means that energy is always moving and changing, from hot areas to colder ones, this movement reprersent to us an ever changing system which respond to our reinterpretation of borders. *Exper ime nt by Ni c k y H oln e ss for th e te a m
II_IDENTIFYING THE P ROBL EM
4 billion tons
of waste will be generated yearly in the world by 2100
1.3 billion tons of waste are generated yearly in the world. This amount is projected to reach 4 billion by 2100, according to Ede Ijjasz-Vasquez, senior director for the World Bank’s Social, Urban, Rural and Resilience Global Practice. The world’s garbage is predicted to grow exponentially in the coming decades as people become richer and increasingly move to urban areas, as we explained before. By 2025, according to a World Bank study, the waste produced by cities around the globe will be enough to fill a line of rubbish trucks 3,100 miles long every day. “There is no end in sight to this trend,” the United Nations Environment Program agency says. “Public waste systems in cities cannot keep pace with urban expansion; rapid industrialization is happening in countries that have not yet developed the appropriate systems to deal with hazardous and special wastes.” The UK exports almost two-thirds of its total waste to China, with UK businesses shipping more than 2.7 million tons of plastic waste there and to Hong Kong since 2012, behavior that may be affected because of the new legislation in China. China will stop imports of recyclable waste from January 2018, including mixed paper, plastic bottles and 24 types of solid waste, saying much of the waste it imports from the UK and other countries is too hazardous to recycle and is causing them an increasing problem. “Instead of confronting our growing problem with throwaway plastic at home, we have been shipping it off to places like China where it’s easier for us to ignore,” said Elena Polisano, oceans campaigner for Greenpeace UK.
UK EXPORTS ALMOST TWO-THIRDS OF ITS TOTAL WASTE TO CHINA, WITH UK BUSINESSES SHIPPING +2.7 MILLION TONS OF PLASTIC WASTE SINCE 2012 UK with an imminent Brexit, is facing a more complex position on this topic. EU has a targeted to restrict all the countries to only landfill 35% of their biodegradable municipal waste of the 1995 baseline by 2020. This target may be affected because of the uncertainty of the costs UK may face to export waste for energy use to other EU countries. London generates an enormous amount of waste every year. In 2016, local authorities collected 3.7 million tons of waste – enough to fill more than 1,500 Olympic-size swimming pools 1. Despite attempts to reduce waste through reuse and repair, the total amount of waste generated in London has only slightly reduced over the last decade. More is being incinerated than ever before, and recycling rates have now dropped back down to 2010 levels. A rising population means more waste and an increasing challenge to waste infrastructure in London. In 30 years, London’s population is estimated to grow to between 10-13million. 2 If Londoners continue to produce the same amount of waste per person it would require local authorities to collect nearly an extra one million tons of waste, equal to an extra 500,000 refuse trucks of rubbish on London’s roads each year 3. Experts have warned that this growth will be unsustainable and put an increasing strain on waste infrastructure, land and resource. 1.

by uses that degrade the future for waste, changing
landscape, there is a need to dethe way city deals with waste.
Garbage is a problem with which the city is dealing, because of the quantity of waste produced despite the recycling policies, problem we cannot hide. If we consider the amount of waste generated per year, in 25 years city of London will produce mountains of garbage of about 3 meters. From this view of reality in city, we need to design a resilient view of garbage for reality by how the city deals with waste. Cities can benefit changing the concept of waste. It is possible to change an unwanted material into a construction one, to build something which scale is beyond architectural possibilities, changing even natural systems like climates. This adaption and reanalysis of waste as a construction material By changing the way waste is deposed and reanalyzing it as a construction material will help support the future city expansion. Using waste as a processed material it is possible to create a landform to produce a microclimate that increases heat in the greenbelt modifying natural systems and brownfield, restoring land, creating energy and providing future farming for London. *G ra phics by Ju an Pa blo D e lla M a g gi ora for th e te a m

_ NATUR A L SYSTEM Wind a nd la nd for ms
It is possible to force the rise of moist air over hills and condense it into clouds just by modifying heights in the existing landscape. Consequently, this fascinating effect on the weather can result in an increase of rainfall. As an output effect, the air loses its moisture after flowing over the altered topography, and increases temperature as it descends again into low lands. This natural condition presents a unique opportunity to manage future farming around London, where conditions of prevalent winds can be used. Rising land over flat existing land surface increment also the productive area. Anabatic winds can blow up heat from a slope that is heated by sunshine. This means that creating a surface that can storage heat will increase the possibilities of warming land and flowing upslope the mountain for produce rain to the other side. This action has a tremendous impact locating properly hotspots. It is possible to produce artificial insolation of the slope for increase wind condition: a landform that changes climatic conditions of landscape. *G ra phic by Ju a n Pa blo D e lla M a g gi ora for th e te a m

The experiment consisted in simulating a slope with different levels using a concrete cast. The objective was to udestand how the heat can be moved in space. Using heated iron bars tested at different levels at the slope it was setted a certain static temperature in one particular layer (condition phase N°1). WIND SOURCE

Using an opposite T° source, cold water, the concrete model was then slowly fooded in the lower levels (pase 2). It was observed that the higher levels started to rise temperature gradually after several minutes (phase 3 and 4). After 20 minutes it was observed that there was a gap with raw difference of temperature between water (lower levels) and the levels above the heated object (phase 5). So it was tested that when flooding certain gap temperature will rise getting out of it. *G raphics by Ju an Pa blo D ella M ag giora for th e te a m

The system is informed by programs that define the shape, orientation, height, and other parameter taken in consideration to design the landform. These programs aim to lead a reinterpretation of the greenbelt, its perception and actual identity. The landform will be built from waste and is planned to have a biomass power station circumscribed on it to generate more heat as well as processing the crops generated by the other activity, which is agriculture.

Landfills are classified according the material they can storage: Construction and industrial waste are that produce more garbage and have some toxic components that cannot be buried (60% of all the waste produced yearly. Other deposals are spetialiced for household waste (municipal solid waste) and agricultural waste, which produce methane gas and can be used to remediate soils. All the landfill types are located beyond the limits of the city, around greenbelt in east, south and west, in territories where the poorest soils are located. Poor soils means not only in terms of agricultural production but also in drainage capabilities. Landfill infrastructures looks for sites with no drainage for not contaminating drain water. By this characteristics and the waste heat capacity of the materials buried or storage, landfills are an important component of heat arising anomalies in the landscape. *G ra phics by Ju an Pa blo D e lla M a g gi ora for th e te a m

Waste deposals have toxic components that does not affect non-comestible crops. In this way, it would be extremely useful if this hybrid system can make grow bio fuel vegetation. Along several years of waste deposal many specific sites can be created for an efficient agriculture that supports the current UK energy crisis. Landfill sites can be used to harvest biofuel crops to generate renewable energy from former rubbish dumps. *Graphics by Juan Pablo D ella M aggiora for the team

After a research about landfills, their characteristics and sizes, we arrived to the conclusion that the average size was 150 x 400 m. The shape exploration started as a simple rectangle with the basic dimensions to find the behaviour of wind, that is one of our major design tool. By flexing the rectangle into a more boomerang alike shape we discovered it produced a bigger shadow of wind, which represent more agricultural area for the system, as well as much more stability by the reduction of vortex in sharp cornes (scenario faced with the rectangle). *Exper iment by Nick y Holnes s for th e te a m

The microclimates we are generating by the distribution of these landforms, will be used for agriculture lands. We aim to generate this new paradoxical concept of the greenbelt that feeds the city with the energy generated from the waste. The borders will be invisible and dictated by these new microclimates, limits without lines. In other words, sensorial limits would be the reinterpretation of the greenbelt into a girdle. As we mentioned before, there are several elements that influence in the aerodynamic of a shape, reason why we started creating a smother face to wind and a more rough one to the shadow of it. This duality of faces is also related in the visual effect of the lanform, as it has a more smooth and natural for the hillside that is covered with materials with heating properties. The opposite side, with a more rough and man mande shape has a natural use with the rapeseeds for biofuel. *Simu l ati on by Ni c k y H oln e ss for th e te a m

Landfill program require buffers to mitigate wind in order to protect the waste that is being deposited. By this principle, we tested buffers shapes with a smoth shape to avoid vortex in the corners.

Landfills require vegetation while they are been filled in order to avoid waste to blow away, as well as giving privacy. By understanding this, we explore the buffers for the system as elements that will protect the landfill activity but also help in the stability and reduction of vortex in the system. Buffers are related to the landfill activity, reason why they do not have a static position but they must be reshaped as the construction on the landform goes. *Simu l ati on by Ni c k y H oln e ss for th e te a m

The microclimates we are generating by the distribution of these landforms, will be used for agriculture lands. We aim to generate this new paradoxical concept of the greenbelt that feeds the city with the energy generated from the waste. The borders will be invisible and dictated by these new microclimates, limits without lines. In other words, sensorial limits would be the reinterpretation of the greenbelt into a girdle. *G ra ph i c by Ni c k y H oln e ss for th e te a m

The metropolitan greenbelt is in great debate, as the housing crisis increases in London. There are several studies that discuss either there is enough or not brownfield to cover the “deficit” in housing. The truth is that this type of concerns and debates, makes us rethink this belt as a girdle (how it was originally conceived) that allows a more permeable development for the always growing city. We propose to decompose the metropolitan greenbelt in several landforms, that may transform and frame the city as well as evolve in time. As the same city have been able to change and adapt through time to different events, we propose to blur the lines in a process of rebirth. The landforms will start with one appearance, but they will change during time until they become part of an active landscape and a real community serving belt.

The first site is located in South East, Surrey county, Reigate and Banstead district; which belongs to the south part of the Metropolitan Greenbelt. As the map shows, there are several hot spots refering to abnormal heat production in the edge of the legally defined greenbelt zone. At the same time, we can also appreciate the location of the spot is before the choosen site, meaning the wind will affect the dome of heat to the site. *M a p ela borated in team by Ju an Pa blo D e lla M a g gi ora a n d Ni c k y H oln e ss

This facts mean for us that we can take advantage of this unwanted conditions to grow vegetation for biofuels, as they can be harvested in poor quality soils.

The site itself does not have a ver y scattered topography, meaning the landfor m will have a bigger impac t. As the map shows, the site is located in a simulated valley, having in consideration that each of the contour lines represent a 5 meter height. All of the previously mentioned fac ts, will shape the way wind and heat is conduc ted to the sytem. The 5m contour lines are presented in brown orange, water bodies in blue, roads in light gray.
As we have previ ously analysed in the hot spots map, the greenbelt has abnor mal heat ac tivities. When we star t analyzing in more detail which is the or igin of this phenomena, we can see that there are pockets of devel opment that allow industr ial uses which are the biggest heat producers. O ur site is situated r ight by the edge of the M etropolitan Greenbelt de fined border (which is represented in a dashed red colored line). The dar k green areas represent the greenspace, while the light green rep resents the area within the greenbelt definition.
R esidential clusters and industr ial par k compose the major it y of the infra struc tures located beside the elec ted site. I t is ver y impor tant to notice that these heat producing infrastruc tures are located to the lef t of the site, meaning the wind will move the dome they generate (as we stated in previous exper iments). The greenspace is defined in green, the blue shows the water bodies, the densified gray indicates the areas that are not within the greenbelt border, while the light pink indicates the occupied land.

The site is located in one of the hot pockes that are generating an irregular heat activity in the limits or borders of the Metropolitan Greenbelt. If we zoom in the site in order to analyze the activities and patterns of infrastructures producing heat, , on the left side of the site we can find residences (in the lowest part) and an industrial park alike zone (in the upper part) that are generating the abnormal heat. *G ra ph i c by Ni c k y H oln e ss for th e te a m

Understanding the wind flow through the shape by the previous studies, we tested what the shape that has given us a more stable wind shadow to see the interac tion when it has a built evironment. As we can see in the grap hic, is not giving the most efficient wind shadow for the agr icultural area.
We made an exploration having different heights in the t wo edges and the middle of the landfor m, understanding we can include the biomass power stations program inside the landfor m to generate more heat. The difference i heights respond to the different chimneys the power stations neeed.

B y adding the agbots (robots used in agr iculture) program to the projec t, we were able to increase the slope of the landfor m as there are no man operated machines needed for the hillside rapeseed agr iculture to take place. As we can see, it makes the system more robust.
As mentioned before, the landfill ac tivit y needs bar r iers to control the wind to avoid the waste to be spread. B y this premise and also by the need to give more stabilit y to the system, we made explorations to understand how this changing vegetation buffer may affec t the wind shadow in the system.

As a strategy, the system must be tested and analyzed within each specific site conditions as the available space for agriculture may vary. By creating a project as a strategy for the Metropolitan greenbelt evolution dealing with the abnormal activities that are taking place, the space available for the project will guide the total height of the landform. Each site may have different characteristics to address. *Simu lation by Nick y Holnes s for th e te a m
