S U M M A RY This narrative follows the prelimenary investigations of the Amazon flora placing species in groups depending on traits, through moments of serendipity reflecting on the relevance of biomimicry, leading into the final device design, that utilized and provided for plants directly instead of mimicking them. Discussing the issues and possibilities of the approach, both pragmatic in terms of microclimatic capability, as well as the complications and potentials of incorporating living organisms in architecture.

Even with ceased deforestation, and a 5% anually reduced global carbon emission, the frequency of abnormal climatic events in the Amazon appear of seasons wil rapidly increase, boding a prolonged dry season with increasingly limited rainfall, and a wet season of localized intense rainfall. Both scenarios having impact on the vegetation, ecosystems and biodiversity of the region, with some species left that are adapted to the climatic change, and some species going extinct. The genetic basis lost forever. One part human deforestation, another part global climatic change; both decreasing biodiversity. which eventually limits the ecosystem services, which onment.

Amazonian fungi come in a wide range of colors, sizes and textures. Although many fungi are edible, in general native Amazonians do not eat fungi. This may be because of the risk of accidentally eating a poisonous species, with potentially fatal consequences. Despite the ecological importance of fungi, they are in much need of more detailed scientific investigation.

BROMELIADS The Bromeliads are a family of monocot flowering plants of around 3,170 species native mainly to the tropical Americas. The most well known species of the family is the pineapple (Ananas comosus). Many bromeliads are able to store water in a structure formed by their tightly-overlapping leaf bases. However, the family is diverse enough to include the tank bromeliads, grey-leaved epiphyte Tillandsia species that gather water only from leaf structures called trichomes, and a large number of desert-dwelling succulents. A bromeliad can serve as a

and relies on nutrients from the air, falling rain, and the compost that lies on tree branches. Their epiphytic way of life gives these plants advantages in the rainforest, allowing them access to more direct sunlight, a greater number of canopy animal pollinators, and the possibility of dispersing their seeds via wind. Despite a commonly held belief that all plants must have soil to grow, epiphytes may never have their roots come in contact with soil. Hemiepiphytes differ slightly since they may grow from a seed dropped on the ground and then climb the host or grow downwards from the host until their roots reach the soil.

Perhaps the most famous hemiepiphyte is the strangler fig tree which starts life as a tiny seed in the canopy of a host tree. The roots grow down to the forest floor where they take root and begin to take nutrients from the soil. Gradually the roots wrap around the host tree, widen, and slowly form a lattice-work that surrounds the host's trunk. The fig's crown grows foliage which soon overshadows the tree. Eventually,

CARNIVOROUS There are several types of carnivorous plants endemic to the Amazon area, that feed on smaller prey. They range from plants with simple traps that act passively to catch insects, like “pitfall” traps, specialized “pitcher” bromeliae, that drown insects who may fall into the plant, subterranean hollow branches with digestive nodes at the end preventing prey from escaping, to traps that spring into action to capture a potential meal. Often growing in nutrient-poor soil, these plants need the

Freshly sawn wood has a characteristic and distinct smell of latex. Since the timber is only moderately durable when exposed to the elements, it should not be used for exterior purposes. The wood is soft, weak and very light in weight; it is extremely vulnerable to decay when in contact with the soil. The fibre from the inner wall of the fruit is light (one eighth the weight of cotton). water repellent and buoyant, making it ideal for life jackets, lifeboats and other naval safety apparatus.It is an excellent thermal insulator, being used in iceboxes, refrigerators, cold-storage plants, offices, theatres and aeroplanes.

PRELIMENARY INVESTIGATION My investigation is anchored in the discovery of microclimatic conditions in specific epiphytic plants, that do not require soil to grow. The device provides the necessary water and nutrients through a ceramic rainwater buffer, and the plants extend the evaporative cooling capabilities. Besides the comfort and performance driven aspects, I wanted to discuss how integrated ecology could be beneficial in an urban context. In the investigations prior to the conceptualisation of the device, it became clear that not only does the climate differ dramatically when comparing the environments of the Brazilian Amazon to Northern Europe, but so does the fundamental aspects of plants, biology and rainwater composition. The investigation went into remarkable cases regarding the fundamental technologies and misconceptions of plants. How the timespan of millions of years through natural selection have created sophisticated ‘biological technology’ that has enabled vascular plants to function in ways, which should be impossible through our current knowledge of physics. The project situates itself in contrast to conventional biomimicry, as the natural technology is not imitated, but directly used and applied. Developing into an alternate discourse that capitalize on existing locally available resources; epiphytic air plants and nutrients in collected rainwater.
Impossible. The pressure required for drawing water more than 10 meters from the roots of a tree to the leaves, exceeds that of a perfect vacuum. The evolutionary adaptation, and sophisticated growing pattern is not possible to replicate by contemporary technology.
The fibre from the inner wall of the fruit is unique in that it combines springiness and resilience and is resistant to vermin making it ideal for stuffing pillows, mattresses and cushions. Wood is susceptible to termites.

DEVICE
Precipitation Condensation of water vapour in the atmosphere causes rainfall.
Condensation
Evaporation
As air has a threshhold for how much water it can contain related to it’s temperature a decrease in temperature causes the air to release the vapour as water. This is most noticable when warm humid air is in contact with a cold surface.
The surface of a liquid is vapourized if the air around it is not fully saturated with vapour of the liquid. This threshold is determined by temperature, as hotter air holds more vapour. The change of state, absorbs energy, and results in a temperature drop in the liquid.
Transpiration
Difussion
Through a (organic) material that doubles as insulation. Humid air is condensed, then moved through capillaries to the outside where it evaporates.
Evaporation of water from leaves and plant cells, causing an increase in humidity.
Capillary Action
Due to the polarity and surface tension of H2O. Water will “climb” tubes smaller than 200 micrometer against gravity.
The spontaneous movement of molecules going from a high to low concentration.
Using Capillary Action to transport humidity
As aircondition systems use evaporation and condensation to cool the air and dehumidify it, a biproduct is distilled water, that could be filtered and use as a source for drinking water.
Organic Fibers
Xylem The plant fibers that move water from the roots to the leaves use capillary action to move water vertically in tubes of a 200 MiMeter D.
‘Wicking’ Wicking is a term used in describing the diffusion of water through a material. EX. water going against gravity through concrete, or sweat clothes.
Includes wool, Kapok endemic to the region, and other materials based on small tubing, allows capillary action.
Utilizing refrigerative properties of evaporation from capillary alternatives The porous structure of earthenware has unique properties, that can be used in layers with water, as a primitive refrigerator. Has been used for centuries in Egypt and India; known as the Zeer pot.
Earthenware One of the most simple clay based ceramics, has not been fired to vitrification, and is permeated by water.
Insulation
Trapped airpockets provide insulation properties. Capillaries in insulating materials can facilitate water transport, through ‘wicking’.
S UB J E C T D E F I N I TI O N Leading on the notion of plants utilizing highly sophisticated properties, that are evolutionary adapted to the context, and exceed our current understanding of physics. A sense of biomimicry was further investigated, through contextual studies on climate, condensation and evaporation. The vertical water movement within trees, that should be impossible, lead to an understanding of the importance and properties of capillary action. The intention was developing methods of creating autonomous cooling systems.

EVAPORATIVE RESIDUE As the ceramic investigations and fabrication went on, a moment of serendipity occured. The first evaporative cooling experiment, had developed white residue on the surface of the terra cotta. Turning out to be mineral deposits contained in the water used for evaporation, the minerals were left as the water molecules evaporated. Proving in integral observation, it lead the study into the chemical composition of rain, and epiphytic plants.

A device is a designed, constructed and deployed instrument of investigation, being an essential part of the Architecture & Extreme Environments masters course. In the preliminary studies, I was imitating the evaporative cooling and capillary action effects discovered in trees. Through a moment of serendipity, a nutrient-rich residue was building up on the experiments, unintentionally. This changed the investigation into using and providing for actual plants instead of biomimicry.

RAINFALL Due to the high levels of rain in the Brazilian Amazon, the plants have developed a water and nutrient cycle, that is independent from the soil. Molecules necessary for metabolism and growth are emitted through decomposition into the atmosphere as aerosols, where water released through transpiration of the trees condense around the particles, generating perspiration. This process essentially makes all of the amazon one cohesive hydroponic system, allowing life to exist in all areas of the region, as well as causing widespread implications when interfered by intense localised deforestation.
MICROCLIMATE To test the occurence of microclimatic conditions within the vegetation of the rainforest, I went to the Botanical Garden of Copenhagen. Studying epiphytic growth endemic to the Amazon region, with thermometer, I was astounded to record microclimatic conditions not just within the plants, but adjacent to the stem as well. First noted in a study from 1983, the microclimatic conditions provided by evaporative cooling and transpiration, provide a lowered temperature creating localized eco systems in and around the plant. Attracting species that are beneficial to the survival of the plant, the microclimate is the fundamental condition for symbiotic relationships.

M A N AU S HEAT ISL AN D The City of Manaus within the Amazon rainforest, in the state of Amazonas, where Rio Negro and Rio Solimoes meet to form the Amazon river. The urbanization process produces significant changes in land surface and atmospheric properties, such as the energy partitioning between urban and adjacent areas, thereby creating a new urban climate, which can be understood as a local inconsistency of the regional climate. Data collected from two different sites, in an urban area and from a region of forest about 30 km from the city, for the period of 2000–2008, show that the urban environment creates a local increase in temperature and a decrease in relative humidity. The annual average observed between the urban and forest sites can reach differences of temperatures around 3 °C and relative humidity close to 1.7%. The urban area tends to heat first and more slowly and cool down later and faster than the forest. This heat differential is the product of an in the city missing biological cycle, that acts as a source of cooling primarily through evaporation. The high thermal mass of the city is mitigated by imported airconditioning systems primarily of Asian origin, that are poorly adapted to the hot-humid climate. eventually posing a health risk, as biological growth forms in the filters, releasing unhealthy pathogens.

E P I PH Y TIC CON D IT ION IN G In the investigations prior to the conceptualisation of the device, it became clear that not only does the climate differ dramatically when comparing the environments of the Brazilian Amazon to Northern Europe, but so does the fundamental aspects of plants, biology and rainwater composition. The investigation went into remarkable cases regarding the fundamental technologies and misconceptions of plants. How the timespan of millions of years through natural selection have created sophisticated ‘biological technology’ that has enabled vascular plants to function in ways, which should be impossible through our current knowledge of physics. The project situates itself in contrast to conventional biomimicry, as the natural technology is not imitated, but directly used and applied. Developing into an alternate discourse that capitalize on existing locally available resources; epiphytic “air plants” and nutrients in collected rainwater. The system has 3 main parts; the ceramic water buffer that can be connected through tubes to a water source or aircondition run-off, the capillary water retaining fabric, and the aluminium frame, that can fold into a backpack size, while protecting the plants in the collection phase. The implications in moving plants from their natural habitats into the unnatural context of an artificial ecosystem, was essential to the project. The notion that some plants would die, some compete and others bring unanticipated fungus and growth into the system, was considered a value that would eventually contribute to the ecosystem it could become. It would develop its own time, rhythm and biological composition, as a temporal ecology.
SUMMARY The Biotube is a fabricated prototype of a cultivation biotope. Comprised of 2 vertical growth chambers both monitored and the bottom regulated by an Arduino microcontroller to sustain the humidity, temperature and light conditions for epiphytic plants. One part automated cultivation, the other and experiment of placing selected plants at the interface of the two chambers measuring the effect of the plant as a active biological transition between two conditions.
BIOLOGICAL DEHUMIDIFICATION GAS EXCHANGE & TRANSPIRATION The main experiment in the biotube, is the notion of epiphytic plants being aplied as an active component in the structural membrane. Effects of dehumidication is monitored, by increasing the humidity of the buttom chamber, and recording an increase in the top. only interface being the roots and leaves of the plant

EPIPHYTIC CULTIVATION GROWTH CYCLES & Plant MORPHOLOGY Through the experiment period, the growth under different conditions is monitored, as well as recorded in photos. The main interest being the capabilities of growth on purely synthetic elements. As epiphytes do not draw any nutrients from the host body, the application range is tested.

NOTE: The first test was an unexpected success, the humidity level increased rapidly with no measurable loss in the bottom chamber, at about 1% per minute. No effect on the top chamber, even with a small 9mm hole connecting the two. The sensor matched readings on external measuring devices, and fell to a steady 38% as the chamber was ventilated by the end of the test. No condensation and an interesting phenomena of a cloud building up at the bottom as the chamber fills. Shutoff as expected. Ventilation can be increased for a more frequent humidification event.
